Home Gardens Management: Improving Soil Fertility and Total Microbe State (Case on Pacitan District, East Java, Indonesia)

Research has been carried out to explore the potential for living the biological properties of the soil in three different home gardens systems. The research was conducted in Pacitan Regency, East Java on three home gardens systems namely the active home gardens, the passive home gardens (home gardens with low maintenance), and the critical land home gardens system (degraded land). Each consists of 20 sites. Observations were made on potential hydrogen (pH), organic carbon, organic matter, total N, total P2O5, available P2O5, total K2O, and total microbe. The results showed that the degraded home gardens were on poor soil fertility and total microbe state. Passive home gardens (low maintenance) could improve the quality of soil fertility and total microbe, especially on active management home gardens.

Evaluation on soil fertility quality under biochar combined with nitrogen reduction

A two-year consecutive field experiment was conducted in purple soil in southwest China, to clarify the effects of biochar (0, 10, 20 and 40 t ha−1, namely, B0, B10, B20 and B40) combined with nitrogen reduction (100%, 80% and 60% of conventional nitrogen application rate, namely, N100, N80 and N60) on soil fertility. The performance of thirty-four indices related to soil chemical, physical and biological properties was evaluated by gray correlation analysis, principal component analysis and cluster analysis to determine the most appropriate mode for soil fertilization, and to identify the main soil environmental factors affecting rapeseed yield under the biochar combined with nitrogen reduction. The results indicated that available phosphorus, geometric mean diameter of water stability, fungi number, and the utilization of sugars, amino acids, polymers and carboxylic acids by microorganisms could be used as the main soil factors affecting rapeseed yield. The highest score of soil quality was observed in N100B10 treatment, followed by N80B10 and N100B20 treatments, which were almost in line with the results of rapeseed yields. Cluster analysis classified 12 treatments into 5 main groups on the basis of the measured parameters, which was mostly consistent with the result of soil quality scores. Considering both economic and environmental benefits, 10 t ha−1 biochar combined with 144 kg ha−1 nitrogen was the best combination to restore crop productivity and soil quality, and to achieve nitrogen decreasing and benefit increasing. This study provided scientific basis for the rational fertilization and scientific management of biochar combined with nitrogen fertilizer in purple soil area of southwest China.

Economic and biological value of pea varieties in solving the protein problem under environment the Trans-Urals

Under the conditions of the Trans-Urals the cultivation of varieties of field pea allows us to get high yields, not inferior to grain, provides high profitability and solves the problem of protein in animal husbandry. Its inclusion in the crop rotation contributes to the improvement of soil fertility, yield and product quality of subsequent crops. Pea seeds depending on the variety and cultivation conditions contain (in % per dry matter): 9–15 water, 18–35 protein, 46–60 nitrogen-free extractives (including 20–50 % starch, 4–10 % sugars), 0,6–1,5 fat, 2–10 fiber, 2–4 ash. The purpose of the research was to determine the economic and biological value of varieties of field pea and the influence of biotic and abiotic factors on crop yield under the conditions of the Trans-Urals. According to the results of three years of study a good level of yield was noted in the varieties recommended for cultivation in the Ural region, which includes the Kurgan region: Aksaysky Usaty 55–2,47 t/ha; Agrointel – 1,88 t/ha, Zauralsky 3–2,12 t/ha, Samarius – 2,40 t/ha. Among the new varieties the high yield was shown by the varieties Kulon – 2,75 t/ha, Yamal 305–1,94 t/ha, Chevron – 1,84 t/ha. The increase in the seed yield of pea varieties with the use of urea (N₃₀) was noted for all the studied varieties. So, for example, for Sibur 2 variety by 1,11 times, for Aksaysky Usaty 55 and Samat varieties by 1,12, for Samarius variety by 1,15 times. The use of urea and double superphosphate (N₃₀P₃₀) to obtain the maximum yield for the studied varieties of peas allowed to increase the yield for the variety Aksaysky Usaty 55 by 1,18 times, Samat and Sibur 2 by 1,17, Samarius by 1,2 times.

Environmental Impact Analysis in the Cement Industry with Life Cycle Assessment Approach

The cement industry is one type of industry that has implications for the emergence of environmental pollution problems and a decrease in environmental quality due to dust pollution. The cement industry can also increase air temperature and noise in operational activities by using machines. In addition, the impact of the cement industry is the decline in the quality of soil fertility due to clay mining. Thus, an analytical study is needed that can be used as one of the policy bases in the operational process of the cement industry. This study aims to conduct an analysis of environmental loads at each stage in the product life cycle, make decisions to identify environmental loads, and evaluate the environmental impact of a product that plays an important role in sustainable development. This method is known as Life Cycle Assessment (LCA). In this study, the boundary system used is cradle to gate with a three-scenario approach. The first uses 100% coal fuel, the second uses 90% coal fuel, and the third uses 10% rice husk biomass. Then the analysis was carried out using the OpenLCA software. The results of the analysis showed that the most significant emission load was carbon dioxide of 1229.31 kg CO2eq. The third scenario produces the lowest carbon dioxide emission load compared to other methods of 849.1 kg.

Variability in Soil Chemical Quality in Traffic-dependent Zones within Field Headlands

ABSTRACT There is increased stress on soil and crop quality caused by machinery traffic during field operations in tillage systems, especially the area where the machinery turns, known as the headlands. While the influence of traffic on soil physical quality is understood, the impact on soil chemical quality and soil fertility is less so. Furthermore, correcting soil fertility and chemical quality in fields under cereal tillage requires strategic sampling due spatial variability, specifically in headlands. Using a simplified sampling strategy, the objective of this study was to examine the variability in soil chemical quality within traffic-dependent zones in the headland. In a case-study in Ireland, 41 fields under tillage were surveyed, and soil sampling zones delineated within headlands based on typical field traffic patterns. Soil phosphorus (P), potassium (K), lime requirement (LR), pH and organic matter (%OM) were measured at two depths. Elevated values of major nutrients (P, K) were recorded around the main headland tramline. Using a generalized linear mixed model, significant differences in P, K, LR and pH were found between headland zones, whereas %OM values did not vary significantly. In addition to laboratory analyses, predictions from mid-infrared spectroscopy (MIR) models resulted in similar patterns in %OM and LR with comparable statistical significance, which highlights the potential of MIR as an alternative to lab analysis of soil in traffic-dependent headland zones. Sampling headland zones to determine soil chemical quality coupled with the application of MIR for rapid soil analysis will improve decision support for soil management in tillage systems.

The Foliar Spray Application of Selected Organic Fertilizers and Their Effects on Selected Plants

Fertilizers are any organic or inorganic natural or synthetic materials [other than liming materials], which is applied to a soil to provide one or more plant nutrients necessary for plant growth. One of the most extreme conditions that have a detrimental impact on the climate is sandy soil. The use of different organic amendments is a tool for developing sustainable development that is both economically and environmentally viable. The aim of this study is to see how milk tea waste extract, banana peel extract and coconut peat extract affect the growth of coriander and spinach plants when applied as a foliar spray. Different pots for various organic fertilizers were used. In this study we discussed how they affected plant growth and how they improved the biochemical properties of sandy soil. The different concentration (2g, 4g, 6g) of banana peel powder, milk tea waste powder and coconut peat were used in this study. The result showed that the highest plant height, root height, number of leaves and shoot height was found in 4g milk tea waste powder in both plants spinach and coriander compared to other fertilizers and control plant. This observation is suggested that the use of milk tea waste is feasible amendment strategy for improving the growth and soil fertility quality of sediments.

Effect of slow-release fertilizer on soil fertility and growth and quality of wintering Chinese chives (Allium tuberm Rottler ex Spreng.) in greenhouses

To avoid the negative impact of excessive fertilization on vegetable production, a decreased fertilization experiment was conducted in a multi-layer covered plastic greenhouse in 2017 to 2018. Treatments included no fertilizer (CK), traditional fertilization (TF), slow-release fertilizers (SRF), and decreased fertilization with slow-release fertilizers (DSRF). Results showed that the SRF and DSRF increased leaf length (13% and 8.3%) and chlorophyll content (7.1% and 8.2%) of Chinese chives compared to TF. Similarly, DSRF was found to increase the accumulation of dry matter accumulation of roots (22%) and the dry matter accumulation of shoots (36%) of Chinese chives. Flavonoid, soluble sugar, and soluble protein content were enhanced by 18%, 8.5%, and 4.6%, respectively, in DSRF compared to TF. Nitrate content of the SRF and SRFR decreased significantly by 26% and 35%, respectively. In addition, there was a significant increase in soil nutrient and enzyme activity in the middle and late harvest of Chinese chives under DSRF compared to TF, and there was a high correlation between soil nutrients and the quality of Chinese chives. The available P and total P content significantly differed among the different greenhouse soil samples, and this significantly affected the quality of Chinese chives. The content of available P and total P in greenhouse soil was 125.07 g kg−1 and 1.26 mg kg−1, respectively. Optimal quality was obtained. Hence, the application of DSRF promoted the growth of Chinese chives and improved soil fertility, thereby enhancing the productivity and quality of Chinese chives.

Collaborative Governance: Re-Enactment Share Understanding in the Process of Agricultural Food Management in Karawang Regency

Sustainable Food Agricultural Land Protection is a system and process in planning, developing, utilizing, controlling, and monitoring agricultural land that is determined to be consistently protected in order to produce staple food for national food security. Currently, food agriculture land in Karawang Regency is increasingly under threat along with the rapid development of the industrial sector in the area and threats from the surrounding area. Not only because of the conversion into industrial land, but the existence of factories around it also threatens soil fertility and water quality due to the factory waste itself. The focus in this paper is how the Karawang Regency Government carries out Collaborative Governance in protecting sustainable food agricultural land. In this study, the authors used a qualitative method with a phenomenological approach. The purpose of this research is to explain how to study and analyze the implementation of policies on the protection of sustainable agricultural land with one of the stages of collaborative governance from Ansell and Gash, namely share understanding. The results showed that the Government of Karawang Regency has succeeded in conducting share understanding in collaborative governance well because it has the same goal, namely to create national food security. Openness and interdependence with each other fosters a sense of understanding. However, the community's understanding regarding PLP2B is felt to be lacking because they have not received good socialization from the Karawang Regency Government.

Soil fertility quality assessment based on geographically weighted principal component analysis (GWPCA) in large-scale areas

Principal component analysis (PCA) has been widely used in the integrated soil fertility quality index (SFQI) (SFQIPCA) assessment. However, the traditional PCA, only established in variable space, does not consider the spatially varying relationships among soil fertility indicators in large-scale areas, and thus cannot appropriately determine the spatially varying relative importance (i.e., weight calculated based on communality) of soil indicators in the SFQI assessment. Moreover, uncertainty inevitably exists in the spatial distribution pattern of SFQI due to the limited sample points, which is critical to the precision management of soil fertility. To address these limitations, this study first proposed a novel assessment method for SFQI based on geographically weighted principal component analysis (GWPCA) (SFQIGWPCA). Secondly, SFQIGWPCA was assessed in Shayang County, China, and then compared with the traditional SFQIPCA. Finally, the spatial uncertainty of SFQIGWPCA was assessed based on the 1000 realizations generated by sequential Gaussian simulation (SGS). Results showed that (i) spatially varying relationships among soil indicators were revealed by Monte Carlo test and GWPCA outputs (i.e., the winning variable and the local percentage of total variation), while traditionally-used PCA was conducted in the assumption of spatially stationary relationships among soil indicators; (ii) in SFQI assessment, the spatially varying indicator weights were determined by GWPCA, but could not be determined by PCA; (iii) the areas with higher threshold-exceeding probability (≥ 0.95) mainly located in the northwest of this county, and the areas with lower threshold-exceeding probability (≤ 0.05) mainly located in the east of this county. It is concluded that GWPCA adequately considers the spatially varying relationships among soil indicators, and SFQIGWPCA is an effective tool in the SFQI assessment in large-scale areas.

Productivity, nutrients uptake and quality of forage oat (Avena sativa) and residual soil fertility as influenced by nitrogen and FYM

A field experiment was conducted during rabi season (2014-16) at Research Farm, R.B.S. College, Bichpuri, Agra (U.P.) to study the effect of nitrogen and FYM levels on growth, yield and uptake of nutrients in oat (Avena sativa L.) and soil fertility. The experiment was laid out in randomized block design with four levels of nitrogen (0,50,100 and 150 kg ha-1) and three levels of FYM (0, 5 and 10 t ha-1) with three replications. The results revealed that the plant height, yields of oat crop increased significantly up to 150 kg N and 10 t FYM ha-1 over control. The maximum values of green foliage (447.16 and 414,03 qha-1) and dry matter yield (64.98 and 60.30 q ha-1) were recorded with 150 kg N and 10 t FYM ha-1 , respectively. The application of FYM alone was also found to be more beneficial in terms of growth and yield of oat crop over control. The interaction effect between 150 kg N ha-1 and 10 t FYM ha-1 recorded maximum yield than other treatment combination. The maximum content (14.14 and 14.10 %) and yield of protein in oat crop (920.6 and 853.5 kg ha-1) were recorded with 150 kg N and 10 t FYM ha-1 but maximum value of crude fiber (32.96 and 33.7 %) were recorded under control, respectively. However, crude fiber content in oat was not affected significantly with N and FYM levels. The uptake of major (N,P and K) and micronutrients (Fe,Mn,Cu and Zn) by oat crop increased significantly with the levels of nitrogen up to 150 kg ha-1 and FYM 10 t ha-1, respectively. The status of organic carbon and available nutrients in post harvest soil improved with 150 kg N and 10 t FYM ha-1.The minimum amounts of available nutrients in post harvest soil were recorded under control treatment.

Effect of chemical fertilizers and organic sources on growth, yield and quality of turmeric (Curcuma longa L.) and soil fertility

Field experiment was conducted for two consecutive years (2018 and 2019) to evaluate the effect of different chemical fertilizers and organic manures on growth, yield and quality of turmeric in district Sangli (Maharashtra). The treatments consisted of 12 combinations of chemical fertilizers and organic manures (farmyard manure, vermicompost and neem cake) including unamended control. Results indicated that application of 50% recommended chemical fertilizer dose (RDF) + 50% N through neem cake was significantly better in improving fresh weight of primary and secondary rhizome, total weight of rhizomes per plant and marketable yield of rhizome (251.2 q/ha) compared to 100% RDF. The treatment of 50% RDF + 50% N as neem cake was also superior for enhancing the quality parameters of turmeric such as fats, protein, carbohydrates and curcumin content. The treatment combinations of 50% RDF + FYM or neem cake or vermicompost improved many of the soil fertility parameters compared to no application of organic manures. The present study reported that combination of organic manures, biofertilizers (Azospirrillium, P solubilizing bacteria) and inorganic fertilizer showed significant improvement in the growth, yield and quality of turmeric along with the improvement in soil fertility.

Effect of phosphorus and biofertilizers with and without FYM on mustard and soil fertility

A field experiment was conducted at Rajasthan College of Agriculture, Udaipur to study the effect of integrated phosphorus management on yield and quality of mustard and soil fertility. The experiment was laid out in split plot design with four levels of phosphorus (0, 20, 40 and 60 kg P2O5 ha-1), two levels of FYM (0 and 5 t ha-1) and four levels of microbial inoculum (no inoculum, PSB, VAM and PSB + VAM). The maximum seed and straw yield of mustard was significantly enhanced with 60 kg P2O5 ha-1, 5 t FYM ha-1 and PSB + VAM inoculation. Significantly higher available N, P, K and S content in soil after harvest of mustard was reported with 60 kg P2O5 ha-1, 5 t FYM ha-1 and PSB + VAM inoculation. Integrated application of 60 kg P2O5 ha-1 + 5 t FYM ha-1 reported significantly higher seed yield, straw yield, oil yield and available P and S after harvest of mustard. Application of 5 t FYM ha-1 along with PSB + VAM inoculation reported significantly higher available P.

Land resource potential of the country as a basis for the development of organic agriculture

Today there is a tendency to deteriorate the quality of soils: lowering the level of humus, increasingtheir acidity, deteriorating the balance of nutrients inthe soil and so on. Therefore, the transition to organic production is one of the necessary conditions for improving the quality of agricultural land and solving the problems of rational use of land resources.The article considers the peculiarities of growingorganic products by producers in the lease of agricultural land, which contributes to the creation of an optimal environment for the development of organic movement and ensures food security.

The transition of agriculturalproducers to organic farming methods is possibleonly if the benefits of organic production comparedto traditional. Therefore, issues of improving the efficiency of organic production remain relevant andrequire further research. The problems that hinder the development of organic production in the conditions of land relations reform are also considered. The issue of effective use of the potential of agricultural lands of agricultural enterprises is considered. The problems of economic and ecological impact on land resource potential, factors that negatively affect the quality and fertility of land are analyzed.It is established that further research should beaimed at exploring the possibilities of using the world experience of organic farming to develop comprehensive programs to stimulate those areas and areas of agricultural activity that are developing internationally and meet consumer needs and protect and restore the environment.

Isolation, identification and characterization of phosphate solubilizing bacteria in soils of coal mines landfills of Chhattisgarh

Phosphate solubilizing bacteria have the ability to solubilize the insoluble phosphates and to improve the quality of soil health and fertility. Efficacy of phosphate solubilizing microorganisms has been identified on the basis of kinetics and phosphorus accumulation. In this study, twenty eight soil samples were collected from different coal mines landfills of Chhattisgarh and occurrence of phosphate solubilizing bacteria (PSB) was isolated, purified and identified. In addition, the phosphate solubilizing capacity of bacteria based on the formation of visible or halo zone on Pikovskaya agar plates (PVK) and broth having tricalcium phosphate (TCP) and rock phosphate (RP) as a phosphate source was estimated at Dr. C.V. Raman University, Kota, Bilaspur (Chhattisgarh). The result revealed dominance of Pseudomonas syringae as major phosphate solubilizers, along with Bacillus subtillis followed by Pantoea dispersa, Bacillus circulans. Use of these PSB as bioinoculants increased the available P in soil to the extent of 194 and 246 µg/ml of P. the soluble P in case of rock phosphate was less than tricalcium phosphate. The maximum solubilization was observed after 15 days follow by a decrease in amount of soluble P.

Quality-based soil fertility quality assessment of American ginseng main production areas in Shandong province

The soil fertility quality is one of the most critical indicators of soil productivity. It directly affects the yield, quality and agricultural efficiency of Chinese medicinal materials. In order to establish the American ginseng planting soil fertility quality evaluation method based on the effective components of American ginseng, Wendeng district, Weihai city, Shandong province, the main producing area of American ginseng, was cited as a case for the study. Twenty-two 4-years American ginseng sampling sites are located at 7 towns. The samples of soil and plant root were collected in the autumn of 2017-2019. The saponin contents of American ginseng and 11 soil chemical properties were measured. The minimum data set(MDS) for assessment of the quality of soil fertility quality was established by correlation analysis and principal component analysis. The evaluation indexes were normalized by membership function. Soil quality index(SQI) that indicates soil comprehensive fertility quality level was calculated according to the critical value of membership function and weight value of each soil index in MDS. The results showed that the total saponin(Rg_1+Re+Rb_1) content of American ginseng in samples ranged from 1.76% to 7.94%. The yield of 8 plots in 2019 ranged from 3 818.7 kg·hm~(-2) to 8 996.4 kg·hm~(-2). MDS includes organic matter, alkaline nitrogen, exchangeable calcium, exchangeable magnesium, effective iron, effective copper, and effective zinc. Based on the mean of 4.825% of total saponin, threshold value of SQI for the region was determined to be 0.15, and 86.36% of soil samples in the county were above the threshold value. The methods and parameters are applicable to selection of high quality American ginseng planting sites and guiding rational fertilization. It also provides a reference for the evaluation of soil fertility quality of other medicinal plants.

Evaluating Soil Quality for Some Soils of South East El- Qantara

The governmental strategy aims tothe reclamation and cultivation of about 400.000 feddans concentrated mainly in El-Tina Plain (50.000 feddans), South East El-Qantara (75.000 feddans), Rabaa (70.000 feddans), Bir El-Abd (70.000 feddans) and El-Serw and El-Qawarir (135.000 feddans) areas.. The current study revealed the variation in soil fertility status of soils developed on various landforms in the area as the soils were having low to high in organic carbon (1.4 to 21. 5 mg kg-1)and having low available nitrogen (4.32 to 58.30mg kg-1); low to abundant phosphorus (2.06 to 59.23mg kg-1) and deficient to adequate in available K (23.50to 1360mg kg-1) contents. The result showed the value of soil fertility quality index (SFQI) ranging from 0.022381to 0.665533with an average 0.310947. When fertility quality of the studied soils was examined (according to SFQI); only 27.692% of the soils has very low fertility quality, about 40.00% of the soils has Low, about 28.462% of the soils has moderate and 3.846 % has good fertility quality. The soil fertility quality index, easier to compute with fewer parameters, can be used as a quick tool to evaluate soil quality and to measure changes occurring after using different management practices. This study suggests that using soil fertility quality index to evaluate agricultural soil fertility quality can provide similar results even when different indicator methods and models have been used in the study area. In this study, SFQI determined to be the most accurate method for evaluation of soil fertility quality, because it took all soil parameters into consideration and gave the most consistent results. We suggest using the SFQI to evaluate agricultural soil fertility quality for desert soils because of its highest correlation with economic yield of desert soils.

Soil characteristics of Eucalyptus urophylla × Eucalyptus grandis plantations under different management measures for harvest residues with soil depth gradient across time

Abstract The clear-cut burning method for forest clearing has been widely used in Eucalyptus plantations in Southern China for successive planting generations. Harvest residues can provide a considerable nutritional supply for Eucalyptus plantations by affecting soil fertility qualities. Thus, harvest residue management is crucial. This study aims to investigate the effects of different management measures for harvest residues on the soil fertility of Eucalyptus urophylla × Eucalyptus grandis plantations and the changes in soil characteristics at different times and soil depths. We selected an evergreen broad-leaved forest (CK0) and a third-generation E. urophylla × E. grandis plantation (CK) as the control. The experimental plots were burned and retained the harvesting residue after CK harvesting. Soil samples were obtained one month, one year, and five years after burning (B1, B2 and B3, respectively) and retaining (R1, R2, and R3, respectively) the harvest residues. All measured soil properties were significantly affected by depth, stand, and interactions, except for the pH value. Discriminant analysis showed that the effects of different stands on the primary physicochemical properties of soil were higher than those on the microelement and biological characteristics. Varying stands had a significant influence on the primary physicochemical properties of soil across time. All stands were classified into four grades according to soil quality assessment values. The findings showed that CK0 obtained the highest score for grade I, followed by R2 (grade II); B1, R1, and R3 (grade III); and CK, B2, and B3, which had the lowest grade. Soil parameters were affected not only by soil depth but also by different management measures for harvest residues across time. In addition, although no significant difference was found in soil fertility quality between burning and retaining harvest residues in the short term (about a month), the soil fertility quality of a forest retaining harvest residues was significantly higher than that of a forest burning harvest residues in the long term.
