Effectiveness of Biopelet Combination of Biochar, Chicken Manure and Fish Waste To Improvement of Chemical Properties of Sandy Soil and Soybean Plant Growth

Most of the activities of the use of organic fertilizers and natural additions of organic matter in agricultural intensification fields in Indonesia have not been able to compensate for the rate of decline in soil organic matter by the decomposition process. Biochar has high C levels and has The mean residence time (MRT) in long period in the soils. It was proven that biochar application may increase soil Carbon but has not been able to increase the production of plant. Therefore the use of biochar combined with organic waste rich in nutrients is important to be developed. The purpose of this study was to determine the effectiveness of some biochar compositions with sugar cane, chicken manure, fish waste in the form of biopelet fertilizer on improving the chemical properties of sandy soils and the vegetative growth of soybean plants. This study used a Randomized Completely Block Design (RCBD) with 2 factors, namely: the first factor (B): the composition of Biochar consisted of 3 levels, namely: 1) 70% biochar, 15% chicken manure, 15% fish waste (B1), 2) 50 % biochar, 25% chicken manure, 25% fish waste (B2), 3) 20% biochar, 40% chicken manure, 40% fish waste and the second factor were (D): The dose of biopelet fertilizers, consists of 4 levels, namely: 1) Control (D0 ), 2) 2.5 tons.ha-1 (D1), 3) 5 tons.ha-1 (D2), 4) 10 tons.ha-1 (D3). The results showed that the addition of biopelet fertilizer can effectively improve soil chemical properties (pH, C-organic, and CEC) and the availability of NPK of the sandy soil. The effectiveness of increasing the N-total of soil varies by an average of 32.42 to 75.79%; followed by available P varies between 17.46 to 40.69%, and Kexch between 8.7 to 25.67%. Improvement of soil chemical properties and the availability of NPK by biopelet fertilizer applications could increase plant growth, but reduce the weight of root nodules.

The increasing fertility of sandy soil and chili production through the application of organic fertilizers, zeolite and cane blotong

The aim of the research was to determine the increase in soil fertility and chile production on sandy soils due to the effect of giving organic matter, zeolite sand and cane blotong. The research started in May-November. The research was conducted in a greenhouse using a completely randomized design. The treatments given were the dosage of organic fertilizer (20 and 40 tonnes ha-1); the zeolite doses (20 and 40 tonnes ha-1) and cane blotong (20 and 40 tonnes ha-1). The observation variables included the level of soil fertility before and after and the chili production variable. The results of this study were the application of organic fertilizers, zeolites and cane blotong increased physical and chemical properties of sandy soil occurred after treatment. The effect of various treatments was only able to increase chili/fruit weight and chili fruit diameter, whereas zeolite was only able to increase the weight / plant of chilies and the number of chilies.

Productivity of seedlings of Scots pine on alluvial sands of natural and man-made origin

Purpose. To find out quantitative physical and water indicators for which there are significant changes in forest vegetation properties in alluvial sands, as well as to trace their impact on the formation of pine seedling root systems and the accumulation of aboveground phytomass in their plantations. Methodology. The chemical properties of sandy soils were determined taking into account the current requirements of ISO, and their physical and water properties using volumetric cylinders, followed by the calculation of their density, porosity, as well as the coefficients of water content and aeration. The root population of the upper meter layer of sands was determined by the method of monoliths, and plant productivity was assessed by phytomass of medium model trees (7-year-old seedlings, plots 14) and by biometric indicators (22-year-old seedlings, plots 59). Findings. It was found that on alluvial sands with a density of 1.501.66 g × cm-3 in their upper meter thickness, 7-year-old seedlings of Scots pine form a superficial root system (1341.8 g × m-2), which provides accumulation of 2558 kg × ha-1 of aboveground phytomass in seedlings. As the density of sands increases, the production of seedling phytomass decreases. In the case of an increase in density by 14% (1.521.72 g × cm-3), there is a decrease in the mass of roots, in a meter-thick layer of sand (by 53.4%) and aboveground phytomass (by 36%). An increase in the density of sands by 510% with its maximum values (1.741.79 g × cm-3) in a 1030 cm layer causes a decrease in the mass of pine roots by 64.1%. The roots of pine seedlings, for such a density of sand, are not able to inhabit the inter-row space, as indicated by their content in the upper 20-cm layer of sand (2% of the mass of small roots recorded in a one-meter thickness). The phytomass of aboveground organs decreased by 81%, and the seedlings themselves were marked by dwarf growth (were grown by V class of productivity). On sands covered with humus mass of zonal soils, the one meter thickness contained fewer (by 51.4%) pine roots (482.8 g × m-2) than on the control. The share of small roots was smaller (by 61.5%) and that of coarse roots was higher (by 21.5%). Losses of aboveground phytomass per unit area in pine seedlings growing under such conditions can reach 31%, due to the compaction of sands at a depth of 2550 cm (1.671.72 g × cm-3) when they are covered by humus mass and row spacing are overgrown with herbaceous plants (root mass in 60-cm profile 3147 g × m-2) in the phase of their individual growth. Originality. Quantitative indicators of density, porosity and coefficients of water content and aeration of alluvial sands of natural and man-made origin are shown for which the seedlings of Scots pine feature delay in the formation of full-fledged root systems of the surface type, which is reflected in a decrease in the productivity of pine plantations cultivated on the sands, up to the visual manifestation of their dwarf growth. Practical value. The quantitative indicators of their physical and water properties obtained for alluvial sands explain the changes occurring in the structure of the root systems of Scots pine seedlings and the productivity of their aboveground organs. Maintaining the density of sands in the range of 1.501.66 g × cm-3 will allow growing pine seedlings on sands without covering their surface with humus mass, and no-till pre-planting loosening of sands in the rows of future crops allows ensuring the cultivation of multifunctional pine plantations.

Synthesis and characterization of nano bentonite and its effect on some properties of sandy soils

There is an emerging importance for improving the productivity of sandy soils, and enhancing the efficiency of feeding use, especially with the newly reclaimed soil in Egypt. The present study aims to assess the influence of bentonite and nano bentonite application on the physical and chemical properties of sandy soils. Nano-particles of bentonite were prepared by Sonochemical,and bentonite and nano bentonite were characterized by (XRD), (XRF), (AFM), surface area and (FTIR). Field and pot experiments were carried out for studying the impact of adding bentonite (T1)5 ton ha−1, (T2) 10 ton ha−1 and nano bentonite (T3) 250 kg ha-1, (T4)500 kg ha−1 on some sandy soil properties and its nutritional states; Total porosity (TP); Bulk density (Bd); available water (AW); water holding capacity (WHC) and availability of macronutrients. Data indicated that addition of bentonite and nano bentonite resulted in an increase of available water (AW) and water holding capacity (WHC), compared to the control in pot and field experiments (surface 0−20 cm). The increase in AW and WHC was highest at T4, and lowest at T1 treatment. Results showed that T4 treatments significantly increased the biological yield, grain yield and (100-grain weight, 1000-grain weight) of wheat, in comparison to all the treatments in both experiments. The best treatments of nano bentonite were ultimately T4, followed by T2 of raw bentonite, which gave the highest values of elements content (N, P and K) in the soil or grain and straw of wheat crop whether in pots or in field experiments.

Effectiveness of the combination of biopellet, biochar, chicken manure and fish waste to the improvement of chemical properties of sandy soil and soybean plant growth

Most of the activities of the use of organic fertilizers and natural additions of organic matter in agricultural intensification fields in Indonesia have not been able to compensate for the rate of decline in soil organic matter by the decomposition process. Biochar has a high C level and has the mean residence time in a long period in the soils. It has been proven that biochar applications may increase soil Carbon but have not been able to increase plant production. Therefore, the use of biochar combined with organic waste rich in nutrients is essential to develop. The purpose of this study was to determine the effectiveness of some biochar compositions with sugar cane, chicken manure, fish waste in the form of biopellet fertilizer on improving the chemical properties of sandy soils and the vegetative growth of soybean plants. This study used a completely randomized block design with two factors. The first factor (B) was the composition of biochar consisting of three levels, namely: 70% biochar, 15% chicken manure, 15% fish waste (B1), 50 % biochar, 25% chicken manure, 25% fish waste (B2), and 20% biochar, 40% chicken manure, 40% fish waste (B3). The second factor (D) was the dose of biopellet fertilizers consisting of four levels, namely: control (D0), 2.5 t/ha (D1), 5 t/ha (D2), and 10 t/ha (D3). The results showed that the addition of biopellet fertilizer effectively improved soil chemical properties (pH, C-organic, and CEC) and the availability of N, P, and K of the sandy soil. The effectiveness of increasing the soil total-N varied from 32.42 to 75.79%, P-available varied from 17.46 to 40.69%, and exchangeable K ranged from 8.7 to 25.67%. Improvement of soil chemical properties and the availability of N, P, and K by biopellet fertilizer application increased plant growth but reduced the weight of root nodules.

Utilization of the trash biochar and waste of sugarcane to improve the quality of sandy soil and growth of sugarcane

An abundance of sugarcane trash (ST) can be converted into soil amendment to improve soil quality. Pot research was carried out in Malang, East Java from October 2013 to October 2014. The research aimed to study changes in the properties of sand-textured soil due to the application of trash biochar and other sugarcane wastes, as well as its effect on sugarcane growth. The study was arranged in a randomized block design with six treatments and three replications. Treatment includes: 1) ST biochar 10 t ha−1; 2) boiler ash 10 t ha−1; 3) ST compost 10 t ha−1; 4) ST biochar 5 t ha−1 + ST compost 5 t ha−1; 5) boiler ash 5 t ha−1 + ST compost 5 t ha− 1; and 6) control (without soil amendment). The treatments improved the physical and chemical properties of sandy soil, namely bulk density, total porosity, available moisture content, aggregate stability, organic-C, total-N, available-P, exchangeable-K, and CEC. However, the improvement of this soil did not affect the growth and yield of sugarcane. Further research is needed to study the effect of residues from the application of biochar on ratoon sugarcane, and research on sugarcane development land.

Effect of Coapplication of Biochar and Nutrients on Microbiocenotic Composition, Dehydrogenase Activity Index and Chemical Properties of Sandy Soil

Biochar improves soil physical, chemical and biological properties. However, there is a very limited number of studies comparing the effect of various doses of biochar and wheat straw with nutrients on microbiocenotic composition of soil and their connection with selected biochemical and chemical parameters of soil. The aim of this study was to determine the effect of the addition to the soil of wheat straw (WS) and wheat straw biochar (WSB) (300 °C) at 0.2%, 0.5%, 1%, and 2% doses and the addition of nutrients (MF) on microbial community composition (bacteria, fungi, actinobacteria, Azotobacter spp., ammonifiers, nitrifiers, denitrifiers, C. pasteurianum), dehydrogenase activity index, carbon and nitrogen fractions contents and the content of water soluble Cu, Cd, Zn, and Pb. It was demonstrated that coapplication of WS and WSB with MF at 1% and 2% doses increased carbon and nitrogen contents in soil and, in particular, their water soluble fractions (DOC and DON). The synergistic effect of biochar and MF contributed to the increase in the population of soil microorganisms. Dehydrogenase activity index in treatments with the addition of WS, WSB and MF was 1.6–4 times higher compared to the control. The content of heavy metals significantly (p ≤ 0.05) affected dehydrogenase activity and the number of nitrifiers and ammonifiers. It was demonstrated that the content of C and N measured for soil microbial biomass in treatments amended with biochar and MF was much greater than in control treatment and MF. However, our studies suggest that the microorganisms’ response to the addition of biochar with nutrients increased the number and intensified the activity of soil microorganisms.Graphic

STRONTIUM CONTENT IN SANDY SOILS IN AGRICULTURE FIELDS (CASE STUDY: MOUNDOU, CHAD)

During evaluation of physical and chemical properties of sandy soils and theirfertility in Southern part of Republic of Chad it has been revealed that some soilshave very high content of strontium. Its content varies from 10 to 270 mg/kg ofsoil depending on type of soil, depth of soil layers, clay and organic content.Strontium content negatively correlates with total content of calcium andphosphorus in layers of soil. Low CEC (CEC - Cation-exchange capacity) of soilmay be a reason of possible translocation of strontium from higher to lower layersof soils. Strontium content in soils do not relates with level of radioactivity of soilmeasured. The highest content of strontium has been found in soils developed onsome eolian and colluvio-alluvium deposits. Some researchers hypothesize thatsome endemic and chronic diseases such as Kashin-Beck disease, `Dysostosisenchondralis endemic`, endemic hoiter, osteoarthritis might be caused by highcontent of strontium in water and plant foods contaminated with it. Absence ofconsensus on etiological factors of these diseases confirms that it is worthconsidering necessity of further studies of different affects of high content ofstrontium in water and foods on human health directly or indirectly throughcausing misbalance in mineral nutrition.

WATER-SAVING IRRIGATION REGIMES FOR VEGETABLE CROP PRODUCTION UNDER CONDITIONS OF VOLGA-DON INTERFLUVE

Soils of the southern region of Chad are developed on wind-drawn sand and colluvio-alluvium deposits of two main rivers Logone and Chari. This region of Chad is principal agricultural zone of Chad. Evaluation of physical and chemical properties of sandy soils and their fertility in this region revealed that some soils have very high content of strontium. With aim to locate areas with high content of srontium in soil, and to study its dependence on physical properties of soil and translocation of strontium in soil profile nine pedons were dug on different fields intensively used for agricultural production. Using X-ray spectrometric analysis and radiometric measuring of soil samples it has been revealed that Sr content in soil samples varies from 10 to 270 mg/kg of soil depending on type of soil, depth of soil layers, clay and organic content. Strontium content negatively correlates with total content of calcium and phosphorus in layers of soil. Low CEC of soil may be a reason of translocation of strontium from higher to lower layers of soils. Strontium content in soils do not relates with level of radioactivity of soils under study. The highest content of strontium has been found in soils developed on colluvio-alluviumdeposits. Very wide Ca/St ratioin soil samples of alluvial hydromorphic soils may cause increase of Sr content in vegetable food and drinking water. This may be one of etiological factors which directly or indirectly may cause misbalance in mineral nutrition and severe diseases of a man. It worth of considering necessity of further studies of Sr dynamic in soils under different crop production systems and how to mitigate negative effect of natural pollution of soils with this element.

A Study of some Sandy Soil Characteristics Treated with Combinations of Bentonite and Vinasse which Reflected on Productivity of Pea Crop

This study examined the different rates of both bentonite and vinasse as mineral and organic soil conditioners, in combinations, to improve soil chemical properties which should be reflected on pea (Pisum sativum. L,Variety Master B) productivity during the two winter seasons of 2014 and 2015, on sandy soil under drip irrigation system. The experiment was implemented in Ismailia Agricultural Research Station (latitude, 30o 35' 41.901 N and longitude, 32o 16' 45.834 E). The objective of the work is to study the effect of the treatments for bentonite applied were rates of 2, 4 and 6 ton fed.-1 but vinasse with five rates treatments at 0, 0.25, 0.5, 0.75 and 1.0 ton fed-1,respectively. The obtained results revealed that pH values decreased as affected by applied all treatments compared to control treatment, especially with the gradual concentration increase of vinasse. Conversely, both EC and organic matter values increased with increased rates of vinasse and bentonite, in combination. Furthermore, data indicated that values of soil availability nitrogen, phosphors and potassium rise with high rates of bentonite and vinasse as combination compared to control treatment. Moreover, evaluation of pea yield (pods, seeds, straw), as affected by treatments, revealed an increase in yield components. Similar trend was found with total content of macronutrients in pea crop (straw and seeds) in both two studied seasons. Finally, the combination of bentonite and vinasse, working together as mineral and organic soil conditioners respectively, improved the chemical properties of sandy soil, which reflected on the developed pea plant.

SMART USE OF ORGANIC AND BIO-FERTILIZERS TO IMPROVE PHYSICAL PROPERTIES OF SANDY SOIL AND ITS PRODUCTIVITY, OF FABA BEAN AND MAIZE

The major goal of this study was to evaluate the impact of organic fertilizer (i.e town refuse, biogas and FYM) combined with bio-fertilizer (effective microorganism [EM] and the N2 fixer Compomax [CoM] on improveing some physical and chemical properties of sandy soil as well as productivity of faba bean –maize cropping rotation, an alternative cropping system under sprinkler irrigation system.

Effects of different biochars, compost and lime treatments on the chemical properties of sandy soils

Decrease in organic matter of the soil is one of the major threats to soils in Europe and other parts of the globe. Maintaining or increasing organic carbon is a great challenge in agricultural practices. Application of composts and other organic amendments is an important way of compensation of losses of organic carbon at the same time it is solving the placement and recycling of organic wastes and residues. The favorable effect of these amendments on physical, chemical and biological properties has been proved by different studies, however the stability and the rate of the influence is an issue that can be improved.The aim of the presented study was to investigate the effect of carbonates on the solubility of applied organic materials and selected soil parameters. Different biochars, compost and carbonate were added to light textured soil. The pH and E4/E6 rates were studied under laboratory conditions. Beside the increase of soil organic matter content, all studied parameters gave promising results. The decrease in E4/E6 rate suggests that the inorganic carbonates are stabilizing the fresh organic residues and prevent the leaching processes. Improved soil organic carbon stability is very important in light textured soils.Further investigations are undergoing to determine the optimal rate of components and extend the kinds of material available for application.

Conditioning Effect of Different Absorbant Polymers on Physical and Chemical Properties of Sandy Soil

Nowadays, the use of absorbant polymers (hydrogels) for soil conditioning is considered an effective way to solve the problems of water limitation of sandy soils for reclamation of newly desert areas. In this work, the physical and chemical properties of the sandy soil mixed with different concentrations of five types of hydrogels were studied. The used hydrogels were polyacrylic acid (Aquakeep, AKG); sodium polyacrylate (Aqurihop); vinyl alcohol sodium polyacrylate (Igata, IGG); cellulose (Jelfine, JFG); and starch (Was, WG). The used concentrations of each hydrogel were 0.05, 0.1, 0.2 and 0.4% of the soil weight. The results demonstrated that the maximum water absorption capacity differed greatly from hydrogel to another. AKG and WG had the highest water absorption capacity, while JFG was the lowest indicating that using of AKG and/or WG is the best for water conservation in sandy soils. Moreover, for all used hydrogels, the moisture content of the sandy soil increased with all applied pF values at concentrations of 0.05 or 0.1% hydrogel. A decrease in the bulk density and increase in total porosity of the soil was noticed with the increase of the hydrogel concentration. Soil infiltration rate and hydraulic conductivity were decreased due to the increase in water-holding capacity by conditioning the soils with the used hydrogels. Chemical properties were improved by conditioning the sandy soils with studied hydrogels. All hydrogels could lower the pH values but increase the cation exchange capacity (CEC) of the soil depending on the hydrogel concentration. Using high concentration (0.4) of each hydrogel, the soil pH was slightly lowered, while CEC and organic matter were increased noticeably with more available NPK content (nitrogen, phosphorus, potassium content) in the conditioned soils. From overall experiments, addition of WG, IGG, AKG to the sandy soil appear to be the best for retaining moisture at field capacity, which provides more available water to the plants and caused improvement of physical and chemical properties of the sandy soil.
