The use of fertilizer particularly for the inorganic fertilizers has increased annually to cope the global demand of crop production. Nevertheless, inorganic fertilizer is expensive and associate with the negative effects to the environment and the soil structure. Alternatively, agricultural waste can be composted and used as organic fertilizer. Although such fertilizer has low nutrient concentration and solubility, it releases nutrients slowly which makes them available for a longer period. Moreover, this agricultural waste such as biomass and manure from plantation and livestock farms are available in abundance. Therefore, this study was conducted to determine the effects of different types of fertilizer treatments as listed; T1 – inorganic fertilizer (control), T2 – chicken manure, T3 – cow manure, T4 – empty fruit bunch and T5 – cocoa pod husk on the production of cocoa mature tree and its soil fertility. The results have shown that organic fertilizers with its consistency application has produce comparable production with inorganic fertiliser and have no differences in the soil chemical properties between the treatments. Hence, this study has clearly demonstrated that agricultural wastes act as organic fertilizers were able to increase crop production and improved the soil fertility in cocoa cultivation.

With the continuing 20% growth rate in the organic industry, organic vegetable crop production has increased to 98,525 acres in the United States. The requirement for certified organic vegetable producers to implement a soil-building plan has led to the development of soil fertility systems based on combinations of organic fertilizers and cover crops. To determine optimal soil fertility combinations, conventional and organic bell pepper (Capsicum annuum) production was evaluated from 2001 to 2003 in Iowa, comparing combinations of two synthetic fertilizers and three compost-based organic fertilizers, and a cover crop treatment of hairy vetch (Vicia villosa) and rye (Secale cereale) in a strip-tilled or fully incorporated cover crop system. Organic pepper growth and yields equaled or surpassed conventional production when nitrogen (N) was provided at 56 or 112 kg·ha−1 from compost-based organic fertilizer. Soil analysis revealed higher N in plots where cover crops were tilled compared with strip-tilled plots, leading to recommendations for sidedressing N in strip-tilled organic pepper production. Increased incidence of disease was also detected in strip-tilled plots. Postharvest weight loss after 6 weeks in storage was similar in organic and conventional peppers. The addition of calcium and sulfur products in conventional or organic fertilizer regimes did not increase pepper production or postharvest storage potential. Despite application challenges, cover crops will remain as critical components of the organic farm plan for their soil-building benefits, but supplementation with approved N sources may be required for optimal pepper production. Organic growers should conduct their own tests of organic-compliant soil amendments to determine cost effectiveness and value for their site before large-scale application.

Barley is a crop, requires the availability of available nutrients in the soil, especially at the be-ginning of the growing season. The aim of the research was to determine the effectiveness of the aftereffect of using vermicompost when growing spring barley on different backgrounds in the Donetsk region. The studies were carried out according to the methodology of the field experiment of B. A. Dospehova. Research methods: field, supplemented by analytical studies, measurements, calculations and observations. The studies were conducted in 2017–2019 by laboratory-field method in field crop rotation in the experimental sections of the Donetsk SSES NAAS. The repetition in the experiments is 3-fold. The location of the plots is systematic. The soil is alkaline-chernozemic carbonate, having an average supply of mineral nitrogen and mobile phosphorus, low – potassium. The humus content of 4,2 % indicates a high potential soil fertility, but to realize the potential of the culture, additional application of phosphorus-potassium fertilizers is necessary. The technology for growing crops is generally accepted for the farms of the region, with the ex- ception of the factors studied. Variety of barley spring Avers. The experience scheme provides for: control (without fertilizers); background – saturation of crop rotation with vermicompost granular 2 t/ha; background + N30P30K30; background + N60P60K60; N30P30K30. The use of organic fertilizers under the predecessor in crop rotation provided improve nutriti-on conditions for plants, which positively affected the growth and development of spring barley plants. So, on the variants with the use of mineral fertilizers, the highest indices of the number of productive stems and the structure of the crop were noted in the background. The variant where N60P60K60 was added in the background produced the largest mass of 1000 grains – 49,8 g, which is 4,6 % higher than the control. Analysis of the study indicates the positive effect of the aftereffect of organic fertilizer (ver-micompost) on the yield of spring barley. The maximum yield of spring barley was obtained against the background of aftereffect of vermicompost 2 t/ha and the application of mineral fertilizers N60P60K60 – 5,05 t/ha, but due to high production costs, the profitability level is 114,9 %. The application of organic fertilizers under the background provides a yield of 3,67 t/ha and the highest level of profitability of 140,6 %. The optimal technological option provides for the introduction of mineral fertilizers in the norm N30P30K30 amid predecessor saturation with vermicompost. This allows increasing the yield up to 4,90 t/ha (by 1,46 t/ha or 42,4 % to the control) and obtaining a profitability level of 136,1 %. The use only of mineral fertilizer N30P30K30 in severely arid weather conditions of the steppe zone allows increasing the yield by 0,70 t/ha compared to the control but, due to the high cost of pro-duction, leads to a low production profitability of 99,6 %. Key words: spring barley, background, vermicompost, mineral fertilizers, yield, economic effici-ency.

<p>Low soil fertility, pests and diseases are major problems of growth and establishment of cacao seedlings on the field. Cocoa production increases by new plantings and rehabilitation of moribund farms, but a build-up of plant-parasitic nematodes (PPN) causing dieback and declining soil fertility has discouraged many farmers, leading to a reduction in crop productivity.  In this study, the potentials of some organic wastes as fertilizers and their effects on establishment of cacao seedlings in PPN infected soils was investigated at Ibadan and Owena of Southwestern Nigeria. Goat dung (GD), organic fertilizer (OF), organo-mineral fertilizers (OMF) and NPK 15:15:15 were applied at 200, 400 and 600 kg ha<sup>-1</sup>, respectively, to cacao seedlings one month after transplanting, while unfertilized served as control. Results from the experiments showed a significant increase in percentage survival of cacao seedlings under organic fertilizers at Ibadan and Owena compared to NPK and control even at the lowest rate of 200 kg ha<sup>-1</sup> 3 years after transplanting. The incorporation of GD, OF and OMF significantly reduced the population densities of PPN compared to control. Therefore, GD, OF and OMF at 200 kg ha<sup>-1</sup> are recommended for soil application to enhance the field establishment of cacao seedlings in the soil infected with PPN.</p>

Healthy soils are essential for progressive agronomic activities. Organic fertilization positively affects agro-ecosystems by stimulating plant growth, enhancing crop productivity and fruit quality and improving soil fertility. Soil health and food security are the key elements of Organic Agriculture 3.0. Landfilling and/or open-dumping of animal wastes produced from slaughtering cause environmental pollution by releasing toxic substances, leachate and greenhouse gases. Direct application of animal carcasses to agricultural fields can adversely affect soil microbiota. Effective waste management technologies such as thermal drying, composting, vermicomposting and anaerobic digestion transform animal wastes, making them suitable for soil application by supplying soil high in organic carbon and total nitrogen. Recent agronomic practices applied recycled animal wastes as organic fertilizer in crop production. However, plants may not survive at a high fertilization rate due to the presence of labile carbon fraction in animal wastes. Therefore, dose calculation and determination of fertilizer application frequency are crucial for agronomists. Long-term animal waste-derived organic supplementation promotes copiotrophic microbial abundance due to enhanced substrate affinity, provides micronutrients to soils and protects crops from soil-borne pathogens owing to formation of plant-beneficial microbial consortia. Animal waste-derived organically fertilized soils possess higher urease and acid phosphatase activities. Furthermore, waste to fertilizer conversion is a low-energy requiring process that promotes circular bio-economy. Thus, considering the promotion of soil fertility, microbial abundance, disease protection and economic considerations application of animal-waste-derived organic fertilizer should be the mainstay for sustainable agriculture.

Целью работы явились теоретические и практические разработки по системному применению органических удобрений и мероприятий для поддержания бездефицитного баланса гумуса в севообороте, представляющие научно-прикладной интерес для повышения эффективности растениеводства. Органические удобрения являются одним из основных средств производства Российского земледелия, средством, получаемым из собственных источников, которые уже в течение нескольких столетий улучшают плодородие почвы и повышают её продуктивность. Они играют решающую роль в поступлении органических и питательных веществ в почву. В современном земледелии постоянно осуществляется воспроизводство всех показателей плодородия почв до приведения их в состояние, близкое к параметрам модели плодородия для данного типа и вида почв. Однако первостепенное значение принадлежит воспроизводству наиболее важных из них. Таким важным интегральным показателем является наличие в почве сельскохозяйственного назначения органического вещества гумуса. Оно в этом случае рассматривается как вещественно-энергетическая и структурно-экологическая основа плодородия почвы. Эффективное развитие земледелия неразрывно связано с системным применением удобрений и постоянным совершенствованием технологий их внесения при возделывании сельскохозяйственных культур. Для решения этой задачи предлагается разработанная авторами методика применения органических удобрений в системе задач по производству продукции растениеводства и мероприятий для поддержания бездефицитного баланса гумуса в севообороте. При составлении баланса питательных веществ учитываются дозы внесения органических удобрений и вынос по основной удобряемой культуре. Приводятся схема по балансу питательных веществ с использованием удобрений в севообороте, а также классификационная характеристика качества навоза и химический состав соломы. В выводах показано, что основным показателем эффективности питательных веществ является количество валовой продукции, полученной от действия удобрений.The aim of the work was the theoretical and practical development of systematic use of organic fertilizers and measures to maintain a deficit-free balance of humus in crop rotation-those of scientific and applied interest to improve the efficiency of crop production. Organic fertilizers are one of the main means of production of the Russian agriculture, the means received from own sources which within several centuries improves fertility of the soil and increases its productivity. They play a crucial role in the flow of organic and nutrient substances into the soil. In modern agriculture is constantly carried out reproduction of all indicators of soil fertility to bring them into a state close to the parameters of the fertility model for this type and type of soil. However, the reproduction of the most important of them is of paramount importance. Such an important integral indicator is the presence in the soil of agricultural organic matter humus. In this case it is considered as a material-energy and structural-ecological basis of soil fertility. The effective development of agriculture is inextricably linked to the systematic use of fertilizers and the continuous improvement of technologies for their application in the cultivation of agricultural crops. To solve this problem, the authors propose a method of application of organic fertilizers in the system of tasks for the production of crop production and measures to maintain a deficit-free balance of humus in crop rotation. When drawing up the balance of nutrients, the doses of organic fertilizers and the removal of the main fertilized culture are taken into account. The scheme on the balance of nutrients with the use of fertilizers in crop rotation, as well as the classification characteristics of the quality of manure, and the chemical composition of straw are presented. The conclusions show that the main indicator of the effectiveness of nutrients is the amount of gross output obtained from the action of fertilizers.

Пахотные угодья Республики Коми в основном представлены дерново-подзолистыми почвами с низким естественным плодородием, которые без применения удобрений быстро подвергаются деградационным процессам, что резко снижает их продуктивность. Цель исследований: оценка эффективности долговременного применения органических и минеральных удобрений при выращивании картофеля в кормовом севообороте в условиях Республики Коми. Методической основой выполнения работ были комплексные исследования дерново-подзолистых почв, клубней картофеля на участках многолетнего полевого эксперимента, заложенного на землях Института агробиотехнологий ФИЦ Коми НЦ УрО РАН в соответствии с «Методическими указаниями географической сети опытов с удобрениями». Длительный период исследований (более 40 лет) характеризовался различными климатическими условиями, которые отразились на количестве урожая и качестве клубней картофеля. Было проведено 7 ротаций (14 лет) с выращиванием картофеля. Вносили органические удобрения – торфонавозный компост (ТНК) в дозах 40 и 80 т/га (1 и 2 фон, соответственно) под картофель и минеральные удобрения – NPК в дозах 1/3; 1/2 и 1 для восполнения выноса растениями элементов питания. Установлено положительное влияние комплексного применения органических и минеральных удобрений на урожайность и качество картофеля, а также на плодородие дерново-подзолистой легкосуглинистой среднеокультуренной почвы в кормовом севообороте в почвенно-климатических условиях Республики Коми. В результате применения шестипольного севооборота и комплексного внесения удобрений с 1978 года к 2019 году в почвах снизилась обменная и гидролитическая кислотность; повысилось содержание гумуса на 0,5% (в контроле); на 0,2–0,5% (с тремя дозами минеральных удобрений); на 0,3–1,1% (с ТНК); на 0,2–1,6% (при совместном применении органических и минеральных удобрений). Наибольшие урожаи картофеля получены при совместном применении органических (80 т/га) и минеральных удобрений (1 NPК) и составили 37,1 т/га клубней (8,5 тыс/га кормовых единиц). При таком соотношении удобрений показано высокое качество клубней картофеля: содержание крахмала 15,5%, витамина С – 19,4 мг%, сырого протеина – 14,1%. Количество нитратного азота не превышало ПДК (ПДК 250 мг.с.м.). Экономические расчеты показали, что при внесении ТНК 40 т/га + 1 NPК в дерново-подзолистые почвы с.-х. использования в среднетаежной зоне Республики Коми при выращивании картофеля, условный чистый доход составит 68,4 тыс. р. с 1 га, себестоимость 1 т картофеля – 2,8 тыс. р., рентабельность 188,7%. The arable land of the Republic of Komi is mainly represented by dern-sub-ground soils with low natural fertility, which without the use of fertilizers are quickly subjected to degradation processes, which dramatically reduces their productivity. The aim of the research is to evaluate the efficiency of long-term use of organic and mineral fertilizers in the growing of potatoes in feed crop rotation in the conditions of the Komi Republic. The methodological basis for carrying out the works was comprehensive studies of dern-subhead soils, potato tubers on the sites of a multi-year field experiment laid on the lands of the Institute of Agrobiotechnology of the FRC Komi SC UB RAS in accordance with the «Methodological Instructions of the Geographical Network of Experiments with Fertilizers». A long period of research (more than 40 years) was characterized by different climatic conditions, which affected the number of crops and the quality of potato tubers. There were 7 rotations (14 years) with potato cultivation. Organic fertilizers – peat-avous compost (TNK) in doses of 40 and 80 t/ha (1 and 2 background, respectively) for potatoes and mineral fertilizers – NPK in doses of 1/3; 1/2 and 1 to replenish the carry-out of food elements by plants. The positive effect of the integrated use of organic and mineral fertilizers on the yield and quality of potatoes, as well as on the fertility of soddy-podzolic light loamy medium cultivated soil in fodder crop rotation in the soil and climatic conditions of the Komi Republic, has been established. As a result of the use of six-bed crop rotation and the integrated application of fertilizers, metabolic and hydrolytic acidity decreased in soils from 1978 to 2019; humus content increased by 0.5% (in control); 0.2–0.5% (with three doses of mineral fertilizers); 0.3–1.1% (with TNCs); 0.2–1.6% (with combined use of organic and mineral fertilizers). The largest potato yields were obtained from the combined use of organic (80 t/ha) and mineral fertilizers (1 NPK) and amounted to 37.1 t/ha tubers (8.5 thousand/ha feed units). The largest potato harvests were obtained with the combined use of organic (80 t/ha) and mineral fertilizers (1 NPK) and amounted to 37.1 t/ha of tubers (8.5 thousand/ha of feed units). With this ratio of fertilizers, the high quality of potato tubers was also determined: the starch content was 15.5%, vitamin C – 19.4 mg%, crude protein – 14.1%. The amount of nitrate nitrogen did not exceed the MPC (MPC 250 mg.s.m.). Economic calculations showed that if TNK is added 40 t/ha 1 NPK to the dern-sub-ground soils of agricultural use in the medium-sized zone of the Komi Republic when growing potatoes, the conditional net income will be 68.4 thousand rubles from 1 ha, the cost of 1 t of potatoes – 2.8 thousand rubles, profitability 188.7%.
