Fertility management of seedlings and transplants is considered a key challenge in organic greenhouse production. This study was conducted to determine response of greenhouse-grown cucumber (Cucumis sativus) and nutrient release profile to two organic fertilizers and their combinations applied at three different concentrations in organic substrate. The organic fertilizers used were a turkey litter–based compost (TC) and a dairy manure vermicompost (VC). In addition, two control treatments [no fertilization (CK), conventional liquid fertilizer (CF)] were included. For TC, substrate leachate pH decreased for the first 17 days after addition and then increased, whereas electrical conductivity (EC), and calcium (Ca) and nitrate-nitrogen (NO3−-N) concentrations increased and then declined. For VC, EC decreased continuously over time from days 0 to 52, whereas pH increased. The Ca and NO3−-N concentrations decreased over time to 24 days and then did not change further. For TC/VC combinations, EC was stable for the first 17 days and then declined. For all organic fertilizer applications, potassium concentration was stable for the first 17 days and then decreased, whereas most of the sodium, ammonium-nitrogen, and chloride were no longer leached by 24 days. The VC and TC/VC combinations did not affect cucumber seed germination rate, seedling survival rate, seedling height, and leaf greenness (SPAD) as compared with CF. The stem length, leaf number, dry weight (DW), root index, and SPAD readings of cucumber transplants increased with increasing TC and VC fertilizer applications. The TC/VC combinations increased the biomass of cucumber transplants compared with CK, and did not differ from CF. The results of this study indicated that the 28.32 lb/yard3 of VC (high rate) or the 9.44 lb/yard3 of VC combined with 4 lb/yard3 of TC (medium rate) can be substituted for CF for the cultivation of cucumber seedlings. Based on DW, the 12 lb/yard3 of TC (high rate) or the 4 lb/yard3 of TC combined with 9.44 lb/yard3 of VC (medium rate) fertilizers were suitable replacements for CF for the cultivation of cucumber transplants.

In recent years, jackfruit production in Vietnam has been growing very strongly in both quantity and quality. However, most of the jackfruit is harvested and processed for meat, the rest is the jackfruit peels, and fibers are discarded, which will affect environmental sanitation. The study aims to enhance the value of jackfruit by taking advantage of nutrient ingredients in the peel and fiber of jackfruit to blend into organic fertilizer. Initial results show that the compost substrate samples mixed with rice husk ash and coir and the organic substrate sample mixed with coconut fiber had the best quality. Tested nutritional ingredients include including humidity is 76.1%, total organic carbon content is 27.3%, fulvic acid is 0.9%, humid acid is 0.9%, total nitrogen is 0.85%, total phosphorus is 0.57% after 35 days of incubation. Their quality meets the national standards of QCVN 01-189: 2019/BNNPTNT on fertilizer quality. After testing all three samples of organic substrates on the green mustard with germination rate (%), a number of branches, and total fresh weight (g), the results showed that test plants are grown with the compost from the shell - jackfruit fiber mixed with coconut fiber developed better than the control sample.

AbstractIn the context of black soldier fly (BSF) rearing, often the residues from production — mainly faeces but also undigested substrate — are addressed as frass in a broader sense. As BSF production is expanding, the valorization of BSF frass as organic fertilizer is gaining importance. However, in contrast to established organic fertilizers, little is known on the properties and variation of this by-product, which is essential for assessing possible application purposes. To elaborate a first overview on this relatively new waste stream, BSF frass analyses from the literature and anonymized frass analyses enquired from BSF producers were compiled. For a possible agricultural use as a fertilizer, their nutrient patterns were assessed. With a balanced nitrogen:phosphorous pentoxide:potassium oxide (N:P2O5:K2O) ratio of 1:0.9:1.1, BSF frass can be characterized as a slightly alkaline (pH 7.5), nutrient-rich compound fertilizer, with the nutrient and especially the micronutrient contents showing high variation. The comparably high carbon-to-nitrogen ratio and low shares of ammonium nitrogen indicate a limited immediate nutrient release and point to possible applications of frass as a long-term fertilizer. The use of frass as an organic fertilizer as one element in a fertilization strategy is promising. By improving nutrient cycling back to the field, BSF frass can represent an important element of sustainable circular agriculture. However, more information on BSF feed and production systems needs to be combined with the nutrient analyses to better understand the variation in frass nutrient contents.

AbstractIn recent times, research attention is focusing on harnessing agricultural wastes for the production of value-added products. In this study, the valorization of Carica papaya (Pawpaw) fruit peels was evaluated for the production of quality organic fertilizer via anaerobic digestion (AD) while the effects of the fertilizer on maize crop were also assessed. Pawpaw peel was first pretreated by thermo-alkaline methods before AD and analyses were carried out using standard methods. The resulting digestate was rich in nutrients and was dewatered to form solid organic fertilizer rich in microbes and soil nutrients. When applied to maize plants, organic fertilizer showed a better effect on plant traits than NPK 15–15–15 fertilizer and without fertilizer application. These were more pronounced at mid to high organic fertilizer applications (30-to-60-kg nitrogen/hectare (kg N/ha)) rate. Comparison between the values obtained from the field experiments reveals that the organic fertilizer showed better performance in all parameters such as the number of leaves, leaf area, plant height, stem girth, total shoot, and root biomass, and length of the root. However, the chemical fertilizer outperformed all the organic fertilizer applied rates in the average highest size of the corn ear by 1.4%. After harvesting, nutrient elements were found to have bioaccumulated in plant organs (leaves, stem, and root) with the highest values being 29.7 mg/L for nitrogen in the leaf and this value was reported from the experiment with 50 kg N/ha. For phosphorus and potassium, the highest concentrations of 7.05 and 8.4 mg/L were recorded in the plant’ stem of the experiment with 50 kg N/ha. All the treated soils recorded an increase in values of all nutrient elements over the control with the highest values recorded in the experiment with 60 kg N/ha. In soil with 60 kg N/ha, the nitrogen, phosphorus, and potassium increased by 28, 40, and 22% respectively over the chemical fertilizer applied experiment while different levels of increases were also recorded for all other macro and microelements in all the experiments. Thus, agricultural practices by using anaerobic digestates as organic fertilizers is a sustainable method to overcome the dependence on inorganic fertilizers high rate.

Chemical fertilizers currently poison arable agriculture, so organic fertilizers are now a new trend for soil improvement. This study investigates the appropriate ratio of fertilizer use and materials mixed with sewage sludge in the anaerobic co-digestion treatment method, which will best support agriculture. In the study, bio-organic fertilizer was composted of the co-digestion anaerobic with sewage sludge and agricultural wastes such as rice husk, rice husk charcoal, water hyacinth, cassava peel, and then tested on rice. The specific criteria of fertilizers such as total organic (TOC), total nitrogen (TN), and effective phosphorus (P2O5) and plant growth parameters such as germination rate (%), tillering rate, total weight (g) were evaluated. Initial results show the untreated sludge can be impacted negatively on plant development. The concentration of nutrients in the co-digestion composts was meet the requirements of the Ministry of Agriculture’s standards of organic fertilizer. These bio-fertilizers will play an important role in soil productivity and sustainability. Hence, the widespread use of organic fertilizers from waste to partially replace chemical fertilizers will open up opportunities to reduce farming costs for farmers and develop agriculture sustainably.

Organically grown greenhouse sweet pepper crops, as is the case with most year-around greenhouse crops, rely on pre-grown transplants. Production of adequately balanced (source and sink strength potential) healthy organic sweet pepper transplants is a challenge and is often related to early and total harvested yields. Liquid and/or solid organic fertilizers for greenhouse sweet pepper transplants were compared with a conventional liquid fertilizer. Transplants were grown under greenhouse conditions and inoculated, or not, with a beneficial microbial agent, Trichoderma harzianum Rifai, strain KRL-AG2 (Rootshield®). Medium respiration (CO2 efflux) and fluorescein diacetate (FDA) hydrolysis analysis showed a higher microbial activity in the liquid organic fertilizer treatment. Higher microbial activity was observed after 10 weeks than at 5 weeks after transplanting. Transplant development was greater in the liquid conventional fertilizer treatment compared with the two organic treatments. Transplants that received liquid organic fertilizer had greater development compared with transplants that only received water in addition to the initial solid fertilizer. Organic amendment mineralization did not completely fulfill transplant nutrient requirement compared with conventional transplants. Solid fertilization in the growing medium affected plant growth during the first 5 weeks but not after 10 weeks after transplanting. Solid and liquid organic fertilizers at a higher concentration should be provided to reach a similar transplant development because conventional seedlings or other slow-release sources of solid amendments should be added to the growing medium to keep an adequate and constant nutrient release. Providing a beneficial agent to the organic growing medium increased its biological activity but had no effect on seedling growth during this study. Solid organic fertilization (1600 mL·m−3 of shrimp meal with 50 mL·m−3 of kelp meal) combined with an organic liquid fertilization should be used in combination with inoculation with T. harzianum to obtain high-quality organic sweet pepper transplants.

Tomato (Lycopersicon esculentum); a member of the family Solanacea is a commercially important vegetable throughout the world both for the fresh fruit market and food industries. The research was carried out in the green house at Science Laboratory Technology of the Oke-Ogun Polytechnic, Saki, Oyo State. Improved dry seeds of tomato (Lycopersicon esculentum) was obtained from the Institute of Agriculture Research, (I.A.R&T), Ibadan, Oyo State and were subsequently treated with Sodium Azide aimed at determining the effects of Sodium Azide as a known mutagen on tomato grown with organic and inorganic fertilizer. All the parameters were monitored for six-months with everyday documentation of variants (variables). Highly significant differences were observed in the treatments with respect to the studied parameters (seed germination, seedling survival, seedling height, root length, number of leaves per seedlings, height at maturity, number of branches per plant and fruits per plant) and various chemicals found in the soil sample. Treatment and chemical interactions were similarly highly significant in tomato with Sodium Azide and organic fertilizer with respect to all parameters evaluated and the chemical composition showed better performance compared to tomato seeds grown with inorganic fertilizer. Conversely, Sodium Azide could be utilized as an induced of variability for the improvement of tomato likewise organic fertilizers

AbstractNortheastern Thailand relies on agriculture as a major economic activity, and has used high levels of agrochemicals due to low facility, and salty sandy soil. To support soil recovery and sustainable agriculture, local farmers have used organic fertilizers from farmed animal feces. However, knowledge about these animal fecal manures remains minimal restricting their optimal use. Specifically, while bacteria are important for soil and plant growth, an abundance and a diversity of bacterial composition in these animal fecal manures have not been reported to allow selection and adjustment for a more effective organic fertilizer. This study thereby utilized metagenomics combined with 16S rRNA gene quantitative PCR (qPCR) and sequencing to analyze quantitative microbiota profiles in association with nutrients (N, P, K), organic matters, and the other physiochemical properties, of the commonly used earthworm manure and other manures from livestock animals (including breed and feeding diet variations) in the region. Unlike the other manures, the earthworm manure demonstrated more favorable nutrient profiles and physiochemical properties for forming fertile soil. Despite low total microbial biomass, the microbiota were enriched with maximal OTUs and Chao richness, and no plant pathogenic bacteria were found based on the VFDB database. The microbial metabolic potentials supported functions to promote crop growth, such as C, N and P cyclings, xenobiotic degradation, and synthesis of bioactive compounds. Pearson’s correlation analyses indicated that the quantitative microbiota of the earthworm manure were clustered in the same direction as N, and conductivity, salinity, and water content were essential to control the microbiota of animal manures.
