“…However, these benefits were not effective in increase grain yield (Figure 2), thus using OM fertilizers may be economically unfeasible. However, it is noteworthy that the treatments OM 100 and PL 100 presented higher values of AEI in the parameters SDMY and nutrient accumulation than FM 100, since these two add equivalent rates of N, P, and K. The presence of the organic component and micronutrients in the OM fertilizer and in the PL may bring some advantage to plant growth in comparison to strictly mineral fertilization (Grohskopf et al, 2019), but with no consequence in grain yield.…”

“…Dashed line represents AEI of 100% present in MF may result in greater efficiency of OM fertilizers (Antille et al, 2014;Borges et al, 2019). In addition, the presence of the organic fraction could reduce the solubility of the fertilizer, resulting in a more gradual release of nutrients into the soil (Grohskopf et al, 2019;Mumbach et al, 2019). However, these benefits were not effective in increase grain yield (Figure 2), thus using OM fertilizers may be economically unfeasible.…”

The use of organomineral fertilizers in agriculture instead of mineral fertilizers is a way to add organic compounds to the soil, potentially improving its properties and crop production. Our objective was to evaluate the agronomic efficiency of an organomineral fertilizer manufactured from poultry litter and mineral fertilizers. The experiment was carried out in a Humic Cambisol in the subtropical region of Brazil, with high organic matter content, low phosphorus content, and very high potassium content. The study consisted of six treatments: mineral fertilizer (monoammonium phosphate, KCl, and urea), at rates of 100 and 150% of the technical recommendation; organic fertilizer (poultry litter), at 100% rate; organomineral fertilizer (poultry litter + monoammonium phosphate), at rates of 100 and 150%; and control treatment (without fertilization). Between 2015 and 2017, common bean (Phaseolus vulgaris), wheat (Triticum aestivum L.), and corn (Zea mays L.) were sequentially cultivated. Before performing the experiment and at the end of the fourth crop, chemical properties of the soil were analyzed in the 0‐ to 10‐ and 10‐ to 20‐cm layers. The use of fertilizers increased crop yield, but there was no difference between the three fertilizer sources or between the 100 and 150% rates of the technical recommendation. Chemical properties of the soil were altered in a similar manner with fertilization, regardless of the fertilizer source used. According to the results, the organomineral fertilizer can replace mineral fertilizers with equivalent performance.

“…Caption: Mineral Fertilizer (MF) and Organic Fertilizer (OF) The increase in corn productivity was affected by the increase in the application of organic fertilizer in due points (OF5, OF4 and OF2 125, 100 and 25 kg ha -1 ) (Figure 5), while the best result presented in (Figure 6) was the use of mineral fertilizer at 200 kg ha -1 (MF2). Grohskopf et al (2019) using in one experiment two different fertilizers (mineral and organomineral), observed that when applying the organomineral the response in the release of phosphorus was higher in the soil.…”

A high productivity in a culture mainly the corn it is associated with many factors, like technological application, integrated management of plagues and diseases, soil fertility, primarily for the disponibility in soil nutrients. The present study has a its objective to analyze statistically the corn productivity with a different dosage of the 5-10-10 mineral fertilizers and organic bovine composting and develop a logic-based system Fuzzy of the agronomic parameters. The experiment measured corn productivity in five different dosages of mineral and organic fertilizers, being developed in the field at Colégio Agrícola de Toledo (CAET), Toledo/PR, Brazil. The results showed that a specific range of fertilizer dosages (mineral and organic) can increase corn productivity in the second crop. With the Fuzzy model developed, it was possible to verify the importance of the use of optimization tools that can assist in the analysis of experimental data and allow performing simulations capable of inferring points that have not been determined experimentally in the field.

“…Figueiredo et al (2012) observou aumento da produtividade de milho utilizando adubação organomineral. Em solos com alto teor de fósforo, a aplicação de fertilizante organomineral resultou em um aumento de 20% na produtividade de milho em relação ao adubo mineral (Grohskopf et al, 2019). A adubação organomineral apresentou um de ganho de produtividade de soja de 17,31% em relação a adubação mineral, (Duarte et al, 2013).…”

A sustentabilidade da produção de soja (Glycine max (L.) Merrill.) deve obrigatoriamente considerar a utilização de insumos alternativos, que reduzam o custo de produção e sejam sustentáveis do ponto de vista ambiental. Sendo assim, o objetivo do trabalho foi comparar duas formulações de adubação organomineral com adubação mineral, em três cultivares de soja. Objetivou-se também determinar a melhor dose de adubação organomineral para três cultivares de soja. Foram realizados dois experimentos distintos, ambos utilizando três cultivares de soja, de grupo de maturação distinto, submetidas a tipos de adubos (experimento 1) e a doses de adubo organomineral (experimento 2). Os experimentos foram realizados em blocos ao acaso com quatro repetições, sendo avaliados, massa seca de plantas, número de nódulos e componentes de produtividade da soja. O organomineral SQ/CP possui resposta intermediária em relação à adubação mineral, não diferindo do organomineral JN1, sendo superior a testemunha. No primeiro experimento não se observou interação entre adubos e cultivares para produtividade. O fertilizante mineral não diferiu do organomineral JN1, sendo ambos superiores à testemunha. No segundo experimento houve interação entre as doses e cultivares para a variável produtividade, em que a cultivar Nidera 7321 respondeu a até duas vezes a recomendação do organomineral SQ/CP.
