Development of fishwaste compost and its effect on quality of soil and crop

The main objective of this research was production of compost from fish waste generated from the seafood processing industries at Tuticorin district, Tamilnadu and examine the effect of fishwaste compost on crop and soil quality. The fish waste was acidic in pH (6.1) with EC of 3.8 dS/m. The total NPK content of fish waste is 10.17%, 0.20%, 0.74% respectively. It has an appreciable amount of organic carbon 46.22% and secondary nutrients calcium (1.86%) and magnesium (0.15%) respectively. Fish waste was composted with saw dust under the windrow method of composting and analysed. After composting, fish waste compost (FWC) was neutral in pH (7.1) with low soluble salts (EC = 0.38 dS/m). It had a considerable amount of N (1.6%), P (0.16%) and K (0.21%). A pot study conducted on blackgram comprising of different doses of fishwaste compost (0, 1, 2, 3, 4, 5 t/ha) along with recommended dose of fertilizer (RDF). Among the different treatments, application of FWC @ 4t/ha enhanced the growth and yield of black gram and improve the soil quality. From the study, it is evident that fishwaste compost can play a significant role in enhancing the soil properties and performance of blackgram invariant of dose applied.

Effects of Arbuscular Mycorrhiza Fungi and Coffee Pulp Compost in Improving Soil Water Uptake by Chilli Around the Permanent Wilting Point Conditions

Soil water availability to the plants is a range of water content between the field capacity and the permanent wilting point (PWP) conditions. The PWP is defined as the lower limit of soil water content that the plant can extract water from the soil as indicated by the symptoms of wilting plants. This is because plant roots are unable to penetrate the soil micropores that contain the water. The study aims to analyze the effects of arbuscular mycorrhizal fungi (AMF) and compost in enhancing soil water absorption by the plant when the water content is close to the permanent wilting point. Four doses of AMF (0, 5, 10 and 15 g.plant-1) and three doses of coffee pulp-made compost (0, 5 and 10 ton.ha-1) were arranged according to a randomized complete block design with three replicates. Results showed that the application of AMF significantly enabled the plant to improve water uptake when the soil water content was about at the permanent wilting point conditions. The AMF addition of 15 g.plant-1 significantly prolonged the growing period of chili to wither and the plant showed the wilting symptoms at the soil water content of 5 to 7% lower than the no-AMF plants. Improved water uptake under water stress conditions was attributed to increases in the root colonization by AMF.

Tütün Atığı ve Kompostunun Typic Xerofluvent Bir Toprağın Sağlığı ile Kırmızı Biber (Capsicum annuum L.) Verimi Üzerine Etkileri

Tütün atıklarının tarımda kullanılabilme potansiyelini ortaya koyabilmek amacıyla gerçekleştirilen çalışma, tesadüf blokları deseninde ve 4 tekerrürlü olarak tesis edilmiş olup, 2008 yılında Typic Xerofluvent toprakta yürütülmüştür. Ham tütün atığı (T) ve tütün atığı kompostu (TK) 20 ve 40 t ha-1 düzeylerinde, kimyasal azotlu gübre ise 150 ve 300 kg N ha-1 dozlarında faktöriyel olarak uygulanmıştır. Çalışmada mikrobiyal biyokütle C’u, N’u ve P’u (Cmik, Nmik, Pmik), enzimler (alkalin fosfataz, ALKPA; β-glukozidaz, GLU; aril sülfataz, ArSA; proteaz, PRO; üreaz, ÜA; dehidrogenaz, DHG), mikrobiyal popülasyon (amonyum oksitleyici, AOB ve nitrit oksitleyici bakteriler, NOB; genel bakteri, GB; azotobakter, AZB; genel fungus, GF) ile bazı kimyasal özellikler (toprak reaksiyonu, pH; tuzluluk, EC; organik madde, Corg; toplam azot, Nt) belirlenmiştir. Organik materyaller Cmik, Nmik ve Pmik miktarlarını arttırmıştır. Enzim aktiviteleri üzerine azotun tek başına etkisi önemli olmazken, T tüm enzim aktiviteleri üzerine; TK ise ÜA dışındaki tüm enzimler üzerine etkili olmuştur. AZB dışındaki diğer mikroorganizma gruplarını en fazla uyaran T olurken, TK ile AZB’ler daha fazla uyarılmıştır. AOB, T ile % 585, TK ile ise % 354 artış göstermiştir. Corg ve Nt miktarları özellikle T ile artmıştır. En yüksek birim verim N2T2 ve N0T2 uygulamalarında sırasıyla 192.6 ve 192.3 t ha-1 olarak ortaya çıkarmıştır. Akdeniz ikliminin etki altında sulanabilir ürünlerde ham tütün atığı 40 t ha-1 uygulanabileceği gibi, tuzluluğa daha hassas olan bitki yetiştiriciliğinde ise 40 t ha-1 dozunda tütün atığı kompostunun daha iyi bir tercih olacağı görülmektedir.

Application of Tithonia Compost as Alternative Synthetic Fertilizer Source N and K on Young Oil Palm Plantation

Currently, large oil palm plantations are cultivated on ultisol. Ultisol has various constraints in its utilization for the cultivation of plants, because it has high exchangeable Al, low pH, low soil organic nutrient contained, and soil nutrients such as N, P, K, Ca, Mg. Large quantities and continuous fertilizer are needed for a long time. To solve these problems required to look for alternative fertilizers. These alternative fertilizers are expected to reduce the use of synthetic fertilizers without decreasing production and are available forever. Efforts to produce that location organic matter are the right choice. Tithonia can be grown in the form of alley cropping at young palm plantations. A series of experiments have been conducted at Andalas University experimental farm in Padang, West Sumatra Province. This study used the Factorial design. The treatments are tithonia compost and Lime application. There are 3 rd compost doses in 3 replication each treatment. The experimental obtained that tithonia compost dosage 25% and 50% + 25% and 50% synthetic fertilizer were changed soil chemical properties such as increased 0.94 units soil pH, availability of nutrient contained; 6.22% C-organic, 0.25% N-total, 0.37me/100g exchangeable K, 2.74 me/100g exchangeable-Ca, 0.29 me/100g exchangeable-Mg, in the soil, as well as the decrease of exchangeable Al. Furthermore supporting plant growth such as (plant height, plant length, and the number of the leaf). Liming not significantly different for soil chemical properties and growth of oil palm. The higher the compost dose is given the better the growth of oil palms. Cultivation of tithonia as alley cropping at oil palm plantation can be used as composite materials for synthetic fertilizer substitute source N and K

Effect of Manure Compost on Distribution of Cu and Zn in Rhizosphere Soil and Heavy Metal Accumulation by Brassica juncea

Manure compost has emerged as a method of soil amendment for phytoremediation of polluted soil by heavy metals. Pot experiments were carried out to study the effects of different dosages of manure compost (0, 20, 40, 60, 80 and 100 g/kg compost to soil) on the distribution of Cu and Zn in the rhizosphere soil and the accumulation of them by Brassica juncea during the phytoremediation process. The rhizosphere soil and plant tissues were sampled at 42 days after planting to determine the concentration of heavy metals in the samples by using flame atomic absorption spectroscopy. pH value, electrical conductivity, and nutrients (alkaline-N, olsen-P, and olsen-K) increased with the addition of compost. The percentages of exchangeable Cu and residual Cu decreased, while the proportion of other fractions increased with increasing amount of manure compost. The fractions of exchangeable Zn, Fe-Mn oxide-bound Zn, and residual Zn have the same variation tendency as Cu. The variation tendencies of exchangeable Zn, Fe-Mn oxide-bound Zn, and residual Zn are the same as that of Cu. Concentrations of Cu and Zn in the overground and underground parts of B. juncea had a significant increase up to a maximum at 60 g/kg compost and then decreased. Bioaccumulation coefficients reached maximum values of 1.44 and 1.35 in the overground and underground parts of B. juncea at 60 g/kg compost, respectively. The biomass of B. juncea and total metal accumulation in B. juncea increased to the maximum at 60 g/kg compost. Obtained results indicated that appropriate amount of soil amendment is very important aspects for phytoremediation of heavy metal-contaminated soil.

MINERALIZATION OF NITROGEN AND CARBON FROM ORGANIC COMPOST FROM ANIMAL PRODUCTION WASTE

ABSTRACT Elucidating the mineralization of organic composts makes it possible to understand the release of nutrients to plants. The objective of this study was to evaluate the mineralization of nitrogen (N) and carbon (C) from organic compost from residues of the production and slaughter of small ruminants, applied on a Neossolo Flúvico (Fluvents). The compost consists of remains of grass (forage), manure and slaughter residues such as blood, viscera and the carcass of goats and sheep. Under laboratory conditions, two experiments were conducted in a completely randomized design, considering the doses of organic compost at the following levels: zero; 3.75, 7.5, 15 and 30 Mg ha-1. For the N and C mineralization tests, 11 and 32 collection times (sampling periods) were evaluated, respectively. Inorganic N content (ammonium and nitrate) was measured in the N mineralization test, and CO2-C concentration was quantified in the C mineralization test. The largest increments between the applied doses of organic compost from residues of the production and slaughter of small ruminants were 70% and 69% for potentially mineralizable N and C, with amounts of 7.5 and 30 Mg ha-1 at doses of 3.75 and 7.5 Mg ha-1, respectively. Organic C and N from residues of the production and slaughter of small ruminants are rapidly mineralized in the soil (up to 45 days) due to their low C/N ratio.

Improvement of Soil Quality Parameters by Municipal Solid Waste Compost Application in Clay-Loam Soil

Organic matter (OM) content of the soils should be improved for sustainable productions. Municipal solid waste compost (MSWC) is an organic material used in several countries to improve soil OM contents. This study was conducted to determine potential use of MSWC as soil amendment. Field experiments were conducted for two years with single MSWC treatments. Experiments were conducted on 18 plots in randomized complete blocks design with 3 replications. Six different MSWC doses (0, 40, 80, 120, 160 and 200 t ha-1) were applied to experimental plots. Compost doses were calculated in dry weight basis, applied to 21 m2 plots and sunflower was sown as the experimental plant of the study. Following the sunflower harvest, disturbed and undisturbed soil samples were taken from the experimental plots and soil samples were subjected to various analyses. Applied MSWC doses significantly increased soil OM contents, electrical conductivity (EC) and cation exchange capacity (CEC), aggregate stability (AS) and saturated hydraulic conductivity (Ksat) and reduced soil bulk density (BD). Effects of MSWC on soil pH were not found to be significant. Effects of MSWC treatments were more remarkable with increasing doses. MSWC treatments increased soil OM contents about 3 folds and increased CEC by about 25%. MSWC treatments significantly increased salt contents of the soils. Such increases were found to be significant at 1% level in the first year and 5% level in the second year. Increasing OM contents also increase soil aggregation, thus reduced bulk density and increased hydraulic conductivity. Correlation analysis revealed significant correlations between OM and AS. Present findings revealed that MSWC positively influenced physical and chemical characteristics of clay-loam soils of arid and arid climates, but salt contents should carefully be monitored in repetitive uses.

MEDIA TANAMORGANIK DAN POSISI TANAM BENIH PENGARUHNYA TERHADAP PERTUMBUHAN BIBIT KOPI ROBUSTA (COFFEA CANEPHORA )

The study aimed to determine the effect of organic planting media and the position of seed planting on the growth of Robusta coffee seedlings. The study is conducted at the Tabanan Agrotechnology Study Program, Tabanan University, which conducted from July 2019 to September 2019. The treatments are arranged in factorial in a randomized block design (RBD). Two treatments examined in this study were the doses of organic matter in the growing media (0g, 150 g, 300 g, 450 g) and seed position (prone position, upside down, tilted position). The results show that the interaction between organic planting media (soil + coffee leaf compost) and seed planting position did not significantly affect all coffee seedlings growth variables. The dose of organic compost in the growing media has a very significant effect on all growth variables except when growing and the percentage of growth. The dosing of 450 g organic matter gave the highest root fresh weight, fresh stem weight and fresh leaf weight (1.00 g, 2.97 g and 8.64 g respectively) and oven dry weight for the three variables (respectively 0.39 g, 0.55 g and 1.36 g). Seed planting position has no significant effect on all observed variables, but there is The tendency of planting position with the prone on average gives better growth compared to other positions.

Test of Corn Leaves (Zea mays) Compost and NPK Phonska Fertilizer on Plant Height and Peanut Yield (Arachis hypogaea L.). This study aims to determine the effect of giving corn leaf compost fertilizer and NPK phonska fertilizer and its interactions on the growth and yield of peanuts. The study used a Randomized Block Design with a 4x4 experiment with 2 factorial replications 3 times. The first factor is the dose of compost of corn leaf compost consisting of 4 levels, namely: o0 (control), o1 (100 g / plant), o2 (200 g / plant), o3 (300 g / plant). The second factor is the NPK fertilizer dosage consisting of 4 levels, namely: k0 (control), k1 (5 g / plant), k2 (10 g / plant), k3 (15 g / plant). The results showed that the treatment of corn leaf compost did not have a significant effect on plant height at 30.60, and 90 days after planting, pod weight and number of pods. Phonska NPK fertilizer does not have a significant effect on plant height at 30, 60, and 90 days after planting, but it has a significant effect on the number of pods and pod weight. The interaction between the compost dose of corn leaf compost and NPK phonska had no significant effect on plant height, pod weight and number of pods.

Soil chemical characteristics on coffee plantations fertilized with continuous application of compost and green manure

ABSTRACTSoil characteristics were determined in a coffee plantation after fertilization by five consecutive years with compost and green manure. Compost was applied to provide 25%, 50%, 75% and 100% of the recommended N dose for the coffee crop. Each compost dose was applied alone or combined with 3 t ha−1 of sunn hemp (SH). Linear increment of pH, sum of base (cmolc dm−3), base saturation (V%), cation exchange capacity (cmolc dm−3), effective cation exchange capacity (cmolc dm−3), concentration of P, K, Ca and Mg were detected with exclusive compost. Non-linear increments of pH, V%, concentration of P and Ca were obtained with combined fertilization. SH effect was obtained when associated with the dose 25% N. Higher ratio (Ca+Mg)/K was detected with compost 25% N + SH. The continuous and exclusive application of compost at 25% and 50% improves soil chemical characteristics, but at a dose of 100%, causes unbalance of soil characteristics like pH at slightly alkaline levels, high amount of P available and more probability of antagonism between K, Ca and Mg. The application of SH neutralizes the alkalinity of the compost, less antagonism probability between K, Ca and Mg and allows maintaining a better nutrient balance in the soil.

Effects of Chicken Compost and KCl Fertilizer on Growth, Yield, Post-Harvest Quality of Sweet Corn and Soil Health

This study aimed to determine the effects of chicken compost and KCl fertilizer application on the growth, yield, post-harvest quality of sweet corn (Zea mays L. var. saccharata), soil respiration and microbial population. The research was arranged according to a Factorial Random-Block Design consisting of two factors and three replications. The first factor was the dose of chicken compost (0 and 15 t/ha) and the second the dose of KCl fertilizer (0, 50, 100 and 150 kg/ha). The results showed that chicken compost stimulated the growth, yield, postharvest quality of sweet corn, respiration, and microbial activity of soil. KCl fertilizer increased SPAD values linearly and quadratically chlorophyll pigment, β-carotene, yield components, and yield. KCl fertilizer did not affect soil respiration, fungi, or bacteria populations. The use of chicken compost reduced the need for KCl fertilization by 25%. Therefore, the integration of organic and inorganic fertilizers are recommended to be applied by farmers in the tropics.

The purpose of study was to determine the effect of oyster mushroom baglog compost on the growth and production of several local purple sweet potato genotypes (accessions of Dolok Perdamean with purple tuber, accessions of Silimakuta with purple tuber, accessions of Sumbul with purple tuber, and accessions of Parbuluan with purple tuber) on the various doses of oyster mushroom baglog waste compost application (0, 10, 20, 30 ton/ha). This research was conducted at Jl. Idi Gang Eka Dewi, Medan Johor Subdistrict, from the end of December 2018 to June 2019. The results showed that the administration of oyster mushroom baglog compost gave a good influence on the growth and production of some local purple sweet potato genotypes. The accession of Sumbul with purple tuber had produces the highest growth plant stem length, while the Dolok Perdamean accession with purple tuber had produces the highest on B class tuber grading. The application of oyster mushroom baglog waste compost markedly improves on A class tuber grading. The best dose of oyster mushroom baglog waste compost was 30 tons/ha.

Stable carbon isotope ratios of water-extractable organic carbon affected by application of rice straw and rice straw compost during a long-term rice experiment in Yamagata, Japan

ABSTRACT Hot-water- and water-extractable organic matter were obtained from soil samples collected from a rice paddy 31 years after the start of a long-term rice experiment in Yamagata, Japan. Specifically, hot-water-extractable organic carbon and nitrogen (HWEOC and HWEON) were obtained by extraction at 80°C for 16 h, and water-extractable organic carbon and nitrogen (WEOC and WEON) were obtained by extraction at room temperature. The soil samples were collected from surface (0–15 cm) and subsurface (15–25 cm) layers of five plots that had been treated with inorganic fertilizers alone or with inorganic fertilizers plus organic matter, as follows: PK, NPK, NPK plus rice straw (RS), NPK plus rice straw compost (CM1), and NPK plus a high dose of rice straw compost (CM3). The soil/water ratio was 1:10 for both extraction temperatures. We found that the organic carbon and total nitrogen contents of the bulk soils were highly correlated with the extractable organic carbon and nitrogen contents regardless of extraction temperature, and the extractable organic carbon and nitrogen contents were higher in the plots that were treated with inorganic fertilizers plus organic matter than in the PK and NPK plots. The HWEOC and WEOC δ13C values ranged from −28.2% to −26.4% and were similar to the values for the applied rice straw and rice straw compost. There were no correlations between the HWEOC or WEOC δ13C values and the amounts of HWEOC or WEOC. The δ13C values of the bulk soils ranged from −25.7% to −23.2% and were lower for the RS and CM plots than for the PK and NPK plots. These results indicate that HWEOC and WEOC originated mainly from rice plants and the applied organic matter rather than from the indigenous soil organic matter. The significant positive correlations between the amounts of HWEOC and HWEON and the amount of available nitrogen (P < 0.001) imply that extractable organic matter can be used as an index for soil fertility in this long-term experiment. We concluded that the applied organic matter decomposed more rapidly than the indigenous soil organic matter and affected WEOC δ13C values and amounts.

The effects of compost and biochar on the growth and yield of red chili plants

This research was conducted to examine the effect of compost and biochar on the growth and yield of red chili plants. This research is a factorial experiment using Randomized Block Design (RBD), which consists of two factors: compost (0, 10, 20, and 30 tons ha−1) and the type of biochar (bamboo and coconut shell). The interaction between compost and biochar did not have a significant effect on all variables observed in this study. The dosage of compost has a significant effect on fruit length, fresh fruit weight, and fresh weight of roots. The biochar treatment does not have a significant effect on the observed variables except for the number of fruits that have a significant effect. The treatment of various dosage levels did not show any significant difference, but the application of 30 tons ha−1 compost produced the highest fresh fruit weight of 185.35 g or increased by 20.94% when compared to the treatment without compost of 153.26 g. The treatment of this type of biochar only had a significant effect on the number of chili fruit, namely coconut shell biochar which gave the highest value of 17.17 chilies and was significantly different from bamboo-based biochar which produced 15.00 chilies.

Application of biochar and compost to changes in physical and chemical properties of soil and corn yield on dry land

The purpose of this study was to determine the effect of biochar and compost fertilizer and their interactions on changes in the physical and chemical properties of soil and corn products on dry land. This experiment uses a randomized block design with factorial patterns. The first factor, the biochar dose consisted of 4 levels, namely: 0; 5; 10; and 15 tons ha−1. The second factor, compost dosage consisted of 2 levels: 0 tons ha−1 and 20 tons ha−1. The highest dry corn seed per ha was obtained from the treatment of 10 tons ha−1 biochar which was 9.21 tons which increased 35.56% compared to dry corn seeds per ha which were obtained from the treatment without biochar which was 6.79 tons. The treatment of compost doses of 20 tons ha−1 gave the highest value of dry corn seeds per ha, which was 8.73 tons, an increase of 16.58% compared to the lowest yield, which was 7.49 tons in the treatment without compost. The interaction between the treatment of biochar and compost dosages had no significant effect on all observed variables, except for organic C, available P, available K, and very significant CEC effect.

Critical parameters for integrating co-composting of POME and EFB into life cycle assessment models of palm oil production.

Palm oil mill’s co-products (empty fruit bunch – EFB and palm oil mill effluent – POME) management is a matter of concern in Indonesia. Co-composting is a promising waste management practice that would allow a reduction of environmental impact and a restitution of organic matter to the soil. This study is a part of a Life Cycle Assessment (LCA) project and aims to pinpoint the most environmentally impacting compartments of the palm oil production chain. It deals more specifically with the Life Cycle Inventory of data on the composting process based on site specific data. Data on the recycled biomass, energy demand and yielded compost properties were recorded in an industrial palm oil mill over one year. Due to the local conditions, high nutrient leaching from the compost were recorded and the compost remained very wet and hot (thermophilic phase). The composting process only led to 40% of methane avoidance compared to anaerobic digestion of POME, and the global nutrient recovery efficiency was below 50%. We identified the following critical parameters to increase environmental benefits from composting: i) the POME/FFB ratio from the mill ii) the roofing of the composting platform, iii) the POME/EFB ratio, iv) the turning frequency, v) the recycling of leachates and vi) the process duration and drying period. The nutrient recovery and the doses of compost applied in the field depend on all of those inter-connected parameters. The data presented will be used within LCA models to assess net environmental benefits from various POME and EFB co-composting systems.

The effect of chitosan, arbuscular mycorrhizal fungi, and compost applied individually or in combination on growth, nutrient uptake, and stem anatomy of tomato

This study investigated the effect of chitosan and a complex of arbuscular mycorrhizal fungi (AMF) on tomato plant (Solanum lycopersicum) grown in soil with four doses of compost (C0%, C5%, C10%, and C20%).Scanning electron microscopy with energy dispersive x-ray analysis revealed the interaction of NH2 groups of chitosan with compost nitrogen that was increased by 80% after 24 h of cross-linking. Growth and physiological parameters (root length, fresh and dry biomass of shoot and root, leaf area and Fv/Fm) and biochemical parameters (sugar and protein content) were improved in mycorrhizal plants grown in soil amended with chitosan and 10% of compost (Ch+C10%M+) compared to control plants (ControlC0%M−). This improvement was correlated with the increase of the diameter and the number of xylem vessels of tomato stems. In addition, the application of chitosan and AMF together on plants grown in a poor soil of mineral elements (Ch+C0%M+), increases the stem cortex that is involved in the distribution of minerals.Chitosan application with AMF and 10% of compost was found to be the best treatment for tomato growth. Therefore, adjusting soil with these three bio-fertilizers could be an interesting agricultural tool to help plants adapt in poor soil.
