Abstract The most effective doses of the modified organic-mineral fertilizer (MOF), produced from non-contact pig manure in the conditions of the Rostov region for the purpose of soil reclamation, were determined. Experimental studies were carried out to determine the most effective dose of MOF based on non-contact pig manure. The dependence of the spring wheat yield on the use of a modified organic-mineral fertilizer based on liquid waste from pig farms fermented bird droppings and mineral fertilizers is determined. The equivalence of the effect of a modified organic-mineral fertilizer based on liquid waste from pig farms and fermented bird droppings, introduced in an equivalent dose, on plant biomass was established. When comparing the effects of different types of fertilizers, their toxicity was not established. The introduction of a modified organic-mineral fertilizer based on liquid waste from pig farms at a dose of 2 t / ha provided the highest biomass yield of 34-day-old plants of spring wheat of the “Zlata” variety, which reached 0.9 g/vessel and was 28.5% higher than the control value. A new organic mineral fertilizer with a pH of 8-10, with an organic content of up to 73% per dry weight, can be used for supporting the quality of liming and improving soil.

O mamoeiro é umas das plantas frutíferas mais comuns em quase todos os países da América Tropical. Um dos principais problemas na cadeia produtiva da cultura de mamão é obter bom manejo do material propagativo e garantir uniformidade e qualidade de estande, sendo para isso necessária a obtenção de mudas de qualidades fisiológicas e sanitárias adequadas.  A utilização de produtos alternativos vem demonstrando efeitos significativos no desenvolvimento radicular de várias plantas, o que beneficia a formação de um pomar de maneira rápida, homogênea, permitindo assim a antecipação da colheita e maior lucratividade ao produtor. O objetivo deste trabalho foi avaliar o efeito do organomineral em diferentes doses na produção de mudas da cultura do mamoeiro da cultivar Sunrise Solo Line 72/12, em condições de ambiente protegido. O experimento foi conduzido no viveiro de mudas do Centro Universitário de Santa Fé do Sul - UNIFUNEC, Campus II. O delineamento experimental utilizado foi de blocos inteiramente casualizados, com seis tratamentos (0; 0,050; 0,100; 0,200; 0,300 e 0,400 kg tratamento de organomineral) e quatro repetições (6X4), utilizando 5 saquinhos por repetição, totalizando 120 saquinhos. Os dados biométricos analisados foram altura da planta (cm); comprimento da raiz (cm); diâmetro do caule (cm); massa úmida e seca da área foliar (g) e massa úmida e seca da raiz (g), aos 60 dias após plantio. Com base nos dados obtidos dos caracteres agronômicos analisados, conclui-se que o uso das doses 0,050; 0,100; 0,200 e 0,300 kg por tratamento de fertilizante organomineral promoveu a obtenção de mudas de mamoeiro com maior qualidade fisiológica que são imprescindíveis na formação de pomares comerciais.   REVIEW OF DIFFERENT DOSES OF ORGANIC MINERAL FERTILIZERS FOR PAPAYA SEEDLING DEVELOPMENT   ABSTRACT The papaya tree is one of the most common fruit trees in almost all Tropical American countries. One of the main issues in the papaya cultivation production chain is obtaining good management of propagative material and provide uniformity and quality for sales quality assurance, being to this end necessary to obtain physiological and sanitary appropriate seedling. The use of alternative products has demonstrated significant effects on the root development of several plants, benefiting a fast, homogeneous formation of an orchard, resulting in the anticipation of the harvest and higher profitability for the farmers. This paper aims at reviewing the organic mineral in different doses to produce papaya tree seedling from cultivar Sunrise Solo Line 72/12, in environment-protected conditions. The experiment was carried out at the Centro Universitário de Santa Fé do Sul - UNIFUNEC, Campus II greenhouse. The trial design chosen was the completely randomized blocks, with 6 treatments (0; 0,050; 0,100; 0,200; 0,300, and 0,400 kg organic mineral treatment), and four repetitions (6X4), using 5 small bags per repetition, total 120 small bags. Biometric data analyzed was the plant height (cm); root length (cm); stem diameter (cm); wet and dry mass of the leaf area (g), and wet and dry mass of the root area (g), 60 days after planting.

Conservation agriculture is becoming a priority for Ukraine as well as for many countries of the world. It is a known fact that high content of heavy metals in the soil impairs fertility and carries the risk of crops translocation. An agroecological effect of obtaining and applying organic-mineral fertilizers has been insufficiently studied so far. The purpose of the work is to determine possibilities to produce new organic-mineral fertilizers based on sewage sludge with enhanced adsorbing properties, to establish their agroecological efficiency. Methods. Field, laboratory-analytical, statistical-mathematical. Results. From the agroecological point of view, the production process of organic-mineral fertilizers based on the sewage sludge of Kharkiv is justified. It allows us to expand functional capabilities of reagents, enhancing adsorbing properties of heavy metals. It is proved the advantage of organic-mineral fertilizers over the traditional ones on chernozem typical. After fertilization, the content of total carbon in the soil increased, the content of humic acids increased by 1,5 – 2,8 times, fulvic acids – by 1,1 – 1,7 times, the total sum of humic substances – by 1,3 – 2,1 times compared with no fertilizer option. It is established that application of organic-mineral fertilizers promotes blocking of heavy metals in soil and prevents translocation to plant. Maximum yields of corn were obtained after the local application of granular organic-mineral fertilizers – the yield increase was 41% compared to the control, after introduction of bulk fertilizers – 32% compared to the control. Profit was $ 23 -36 per hectare. Conclusions. The process of organic-mineral fertilizers production on the basis of sewage sludge in Kharkiv is substantiated from the agro-ecological point of view. Agroecological and agrochemical efficacy of sewage sludge use as compared to organic and mineral fertilizers applied in equivalent doses separately was established on the typical heavy loam chernozem. After introduction of organic-mineral fertilizers based on sewage sludge a significant increase in the concentration of trace elements and heavy metals was found in the black soil but these indicators did not exceed the established maximum permissible concentrations. The implementation of the proposed technology will reduce bioavailability of heavy metals and their mobility in the soil which, in turn, impedes their accumulation in products. It is expected to increase soil fertility, crop yields and obtain environmentally friendly and safe products due to the stable composition of innovative fertilizers.

Analysis of modern scientific literature and patents has shown the absence of acid-free production technology of a mechanically activated multicomponent mineral fertilizer containing water-holding substances. Experimental researches connecting with mechanochemical activation and physicochemical properties of Karatau phosphorites prove a possibility of development of a new multicomponent mineral fertilizer. Application of inorganic and organic activators considerably improves qualities of fertilizers because the developed fertilizer mixtures contain nitrogen, phosphorus, potassium, humate and microelements. The suggested technology intends to use wastes of coal mining that leads to presence of humates and microelements in the end product. It was determined, that content of total nitrogen, phosphorus and potassium depends on a form of nitrogen-phosphorus-potassium-containing substances. The given article contains data of researches connecting with use of multicomponent mineral fertilizers in field conditions for cotton cultivation on irrigated light sierozems consisting of soil-forming rocks of loess and loess-type clay loams. The research results show the increase of soil’s fertility and cotton’s productivity. Studying of agronomic efficiency of the new kinds of mechanically activated multicomponent mineral fertilizers at the cultivation of a bean-cereal mixture has been carried out in the Negorelsk experimental nursery-garden of the Belarus State Technical University on a sod-podzol sandy-loam soil and has shown the essential influence on productivity and quality of the bean-cereal mixture. The researches fulfilled on a sod-podzol sandy-loam soil have revealed the essential increase of key indicators of feed productivity. Application of the mineral fertilizers has promoted increase of nitrogen, phosphorus and potassium content in green plants. In so doing content of calcium and magnesium in green mass depends from quantity of the fertilizer used to a smaller extent. An essential difference of crop capacity and feed productivity indicators depending on forms of the applied mineral fertilizers has not been found.

A comparative analysis of the seeds ash composition of the breed Rif (Brassica napus L.) rapeseeds grown in the Lipetskaya region was held. The plants were grown in the conditions of the agroecological experiment using mineral (NPK and zeolite) and organic (hen droppings) fertilizers. 6 variants of the experiment were studied – the plants are grown without fertilizers application (the control); the mineral fertilizer (N60:P60:K60) separately and together with zeolite (5 t.ha-1); the zeolite in pure form (5 t.ha-1); hen droppings (5 t.ha-1) separately and together with zeolite (5 t.ha-1). We studied the accumulation of 9 basic elements (in mass %) contained in Brassica napus. seeds ash using the method of energy-dispersive X-ray spectroscopy. The accumulation order of the elements was determined: P ≈ K > Mg ≥ Ca > Mo > S > Zn > Mn > Fe. The proportion of P fluctuated from 10.852 to 11.855 mass %; the proportion of K – from 9.933 till 12.343 mass %. The rapeseeds contained Mg, Ca, and Mo in similar concentrations within the range of 4.0 -5.8 mass %. The combined application of zeolite with organic fertilizer ensured the accumulation of the minerals in the seeds. Correlations between the elements were established. High correlation between elements K and Mo was found (r = 0.96); P and Mg (0.86); P and Fe (r = 0.94); C and Mo (r = 0.86). The positive effect of the combined organic-mineral fertilizers with poultry farms wastes usage on the mineral elements accumulation in rapeseeds was stated. It is noted that the accumulation of P, Ca, Mo, and S in rape seeds leads to a decrease in Zn.

The problem to provide the livestock industry of the North-West of Russia with forage grain has sharply escalated since 2010. Its successful solution is connected with the level and validity of the use of mineral and organic fertilizers. The purpose of the study, started by the Menkovsky Branch of the AFI in 2012, was to find effective options for the use of new organic-mineral fertilizer (OMF) which provides maximum agronomic effect and can produce grain of high quality. The methodological basis was the micro trials in polyethylene vessels without bottoms of 1 × 1 × 0.4 m in size with an artificially formed upper part of the profile of degraded sandy sod-podzolic soil. The soil was of 4.75 рНKCl, 3.46 mmol (eq) of Ng per100g, 3.20 mmol (eq) of Sch per100g, 1.83% of humus, 217 mg / kg of mobile compounds of phosphorus and 92 mg / kg of potassium. In the course of research, there was high agronomic efficiency of its use for winter wheat and satisfactory agronomic efficiency of its use for barley. When the winter wheat variety ‘Moskovskaya 56’ was fertilized with 5 t/ha of organic-mineral fertilizer containing 2.46% of Ng, 4.51% of P₂O₅ and 3.36% of K₂O, grain yield increased in 2.6 times. Fertilized with N75P50K50 the productivity improved in 3.8 times with a payback of 1 kg of NPK 7.4 and 5.6 grain units, respectively. It has been established that the combination of OMF with mineral fertilizers is accompanied by a significant yield increase with a decrease in its relative contribution from 153% to 59% and from 143% to 105% and a payback of 1 kg of NPK from 3.8 to 2.6 and from 6.9 to 4.7 of barley grain units and winter wheat grain units, respectively. The best indicators of the agronomic efficiency of OMF, both when applied in pure form and when fertilized with N75P50K50, corresponded to a dose of 4 t / ha. It has been found that the addition of 10 kg of potassium (К₂О) per 1 ton to OMF provided yield increase on 15% and the payback period of 1 kg NPK increased from 6.4 to 8.4 grain units. Qualitative indicators of wheat and barley grain fertilized with OMF improved due to the rise of raw protein percentage on 8–27% and a number of ash elements, such as CaO (from 0.07 to 0.11 mg/kg), MgO (from 0.16 to 0.21 mg/kg), Zn (from 21.5 to 23.6 mg/kg).
