“…Similar results were observed by Bhattacharyya et al (2008) when Differences were expected in the recovery efficiency of P because of the different formulations of the analyzed fertilizers (granular OMF or powder MAP), considering that their distinct contact surfaces could affect nutrient bioavailability to plants (Hansel et al, 2014). However, the recovery efficiency of the fertilizers did not differ significantly ( Table 2).…”

-The objective of this work was to evaluate agronomic and P recovery efficiencies of a granulated organomineral phosphate fertilizer (OMF) produced from poultry litter, compared with those of monoammonium phosphate (MAP), in soils with different textures. The experiment followed a 2x2x4+2 factorial arrangement, with two Oxisols (sandy loam and clay loam textures), two sources of P (OMF and MAP), four levels of P (50, 100, 200, and 400 mg kg -1 ), besides two control treatments without P application. The treatments were evaluated in 10-kg pots filled with soil, during four successive cultivations of corn without replacing the P absorbed by the plants, in order to evaluate the actual and residual effects of the fertilizers. Available P contents in the soil were higher with the MAP fertilizer in the sandy loam soil, with no significant differences between fertilizers in the clay loam soil. OMF had a greater immediate effect and promoted a higher dry matter yield in the first cultivation; however, the residual effects of the fertilizers did not differ in the other cultivations. P accumulation by plants was not affected by the fertilizer used. OMF had higher agronomic efficiency, but P recovery efficiency did not differ significantly between fertilizers. OMF performance indicates good potential use of poultry litter as fertilizer, in organomineral formulations.Index terms: Zea mays, biomass accumulation, phosphate fertilization, P recovery efficiency, tropical soils.Eficiência agronômica e de recuperação de P de fertilizante fosfatado organomineral granulado produzido com cama de frango em solo arenoso e argilosoResumo -O objetivo deste trabalho foi avaliar as eficiências agronômica e de recuperação de P de fertilizante fosfatado organomineral (FOM) granulado, produzido com cama de frango, comparadas às do monoamônio fosfato (MAP), em solos com diferentes texturas. O experimento seguiu um arranjo fatorial 2x2x4+2, com dois Latossolos (texturas areia franca e franco argilosa), duas fontes de P (FOM e MAP), quatro doses de P (50, 100, 200 e 400 mg kg -1 ), além de dois controles sem aplicação de P. Os tratamentos foram avaliados em vasos com 10 kg de solo, durante quatro cultivos sucessivos de milho sem reposição do P absorvido pelas plantas, para permitir as avaliações de efeito imediato e residual dos fertilizantes. Os teores de P assimilável no solo foram maiores com o MAP, no solo areia franca, sem diferenças significativas entre fertilizantes no solo franco argiloso. O FOM teve maior efeito imediato e promoveu maior produção de matéria seca no primeiro cultivo; no entanto, o efeito residual dos fertilizantes não diferiu nos demais cultivos. O acúmulo de P pelas plantas não foi influenciado pelo fertilizante utilizado. O FOM apresentou maior eficiência agronômica, mas a eficiência de recuperação de P não diferiu significativamente entre os fertilizantes. O desempenho do FOM indica bom potencial de uso da cama de frango como fertilizante, em formulações organominerais.Termos para indexação: Zea mays, acúmul...

“…Esses resultados indicam que aplicação de altas doses de fertilizantes minerais em solos com baixa e média capacidade de troca de cátions pode não elevar proporcionalmente o rendimento. Uma das maneiras de melhorar a sustentabilidade e a eficiência agronômica dos fertilizantes minerais é a utilização conjunta com resíduos orgânicos (BHATTACHARYYA et al, 2008;LIU et al, 2009). Essa melhoria na eficiência agronômica pode ser percebida no desdobramento da interação doses de cama de frango x doses de fertilizante mineral para altura de planta (FIG.…”

“…A partir desse ponto, a altura das plantas foi decrescendo, evidenciando que neste tipo de solo o aporte de nutrientes através de altas doses de fertilizante mineral pode não ser eficiente, visto que as perdas de nutrientes são grandes. Uma das maneiras de otimizar o uso dos fertilizantes minerais é a utilização associada à aplicação de resíduos orgânicos (BHATTACHARYYA et al, 2008;LIU et al, 2009), como a cama de frango. Observa-se que com a utilização de 3 Mg ha -1 desse resíduo, o efeito do fertilizante mineral sobre a altura das plantas foi linear, atingindo 84 cm com 400 kg ha -1 do formulado NPK, mostrando maior eficiência na utilização dos nutrientes, visto que o valor máximo não foi atingido neste caso (efeito linear).…”

“…Corrêa et al (2008), por sua vez, concluíram que a produtividade da soja é favorecida pela aplicação de lodo de esgoto centrifugado e de biodigestor, escória de aciaria (resíduo da indústria da fundição do aço e do ferro-gusa) e lama cal (resíduo da fabricação de papel e celulose). Bhattacharyya et al (2008) relataram que as culturas da soja e do trigo, cultivadas em sucessão, responderam à aplicação de NPK minerais, mas o rendimento máximo foi obtido com o NPK + esterco bovino, demonstrando a importância da matéria orgânica. Os autores observaram ainda que os rendimentos diminuíram com o tempo nas parcelas sem adubação e nos tratamentos com apenas fertilizantes minerais, ao passo que nos tratamentos onde foi utilizado o esterco foram observados incrementos, ainda relataram que a eficiência agronômica dos fertilizantes foram maiores nas parcelas que receberam adubo mineral mais o resíduo orgânico.…”

), aplicados em área total. As subparcelas constituíram as cinco doses do fertilizante mineral formulado NPK 04-30-10 (0; 100; 200; 300 e 400 kg ha -1 ), aplicados ao sulco de semeadura. A adubação com o fertilizante mineral proporciona aumento na altura de planta e de inserção do primeiro legume, número de legumes por planta e na produtividade de grãos da cultura da soja. A adubação com o resíduo orgânico "cama de frango" eleva a altura de planta e de inserção do primeiro legume, massa de 100 grãos, número de legumes por planta e o rendimento de grãos de soja, porém em doses mais elevadas favorece o acamamento das plantas. A utilização da cama de frango é viável em termos agronômicos e econômicos na cultura da soja. A adição de cama de frango eleva os teores de potássio e enxofre no solo.

Glycine max.Abstract -The objective of this study was to evaluate the effect of mineral fertilizer NPK associated with the organic waste "poultry litter" on the agronomic characteristics of soybean as well as nutrient levels in the Cambisol. The experiment was carried out in Itutinga, southern Minas Gerais state, Brazil, in a randomized blocks experimental design with three replications in split-plot. The cultivar used was BRS Favorita RR. The treatments applied to plots consisted on four doses of "poultry litter" (0; 3; 6 and 9 Mg ha -1 ), applied in the total area. The subplots were the five doses of mineral fertilizer NPK 04-30-10 (0; 100; 200; 300 and 400 kg ha -1 ), applied to the groove seeding. Fertilization with mineral fertilizers provides an increase in plant and first pod height, number of pods per plant and yield of soybean. Fertilization with organic waste "poultry litter" increases the plant and first pod height, weight of 100 grains, number of pods per plant and yield of soybean, however at higher doses favors the lodging of plants. The use of poultry litter is viable in agronomic and economic terms in the soybean crop. The addition of poultry litter increases the contents of potassium and sulfur in the soil.

“…Sufficient evidence indicates that the combined application of NPK fertilizers and organic fertilizers (NPK+OF) can generally achieve higher crop yields than any of them applied alone (Poulton, 1995;Greenland, 1997;Manna et al, 2007;Hati et al, 2007;Bhattacharyya et al, 2008;Xu et al, 2008;Pan et al, 2009;Zhang et al, 2009a, b, c;Diacono and Montemurro, 2010;Zhao et al, 2010). A long-term field experiment from 1973 to 2004 conducted in India indicated a significant downward trend in yield of soybean for both the control treatment and the NPK treatment compared with a statistically significant upward trend with time for the NPK + FYM treatment (Bhattacharyya et al, 2008).…”

-China is facing one of the largest challenges of this century to continue to increase annual cereal production to about 600 Mt by 2030 to ensure food security with shrinking cropland and limited resources, while maintaining or improving soil fertility, and protecting the environment. Rich experiences in integrated and efficient utilization of different strategies of crop rotation, intercropping, and all possible nutrient resources accumulated by Chinese farmers in traditional farming systems have been gradually abandoned and nutrient management shifted to over-reliance on synthetic fertilizers. China is now the world's largest producer, consumer and importer of chemical fertilizers. Overapplication of nitrogen (N) is common in intensive agricultural regions, and current N-uptake efficiency was reported to be only 28.3, 28.2 and 26.1% for rice, wheat and maize, respectively, and less than 20% in intensive agricultural regions and for fruit trees or vegetable crops. In addition to surface and groundwater pollution and greenhouse gas emissions, over-application of N fertilizers has caused significant soil acidification in major Chinese croplands, decreasing soil pH by 0.13 to 2.20. High yield as a top priority, small-scale farming, lack of temporal synchronization of nutrient supply and crop demand, lack of effective extension systems, and hand application of fertilizers by farmers are possible reasons leading to the over-application problems. There is little doubt that current nutrient management practices are not sustainable and more efficient management systems need to be developed. A review of long-term experiments conducted around the world indicated that chemical fertilizer alone is not enough to improve or maintain soil fertility at high levels and the soil acidification problem caused by overapplication of synthetic N fertilizers can be reduced if more fertilizer N is applied as NO − 3 relative to ammonium-or urea-based N fertilizers. Organic fertilizers can improve soil fertility and quality, but long-term application at high rates can also lead to more nitrate leaching, and accumulation of P, if not managed well. Well-managed combination of chemical and organic fertilizers can overcome the disadvantages of applying single source of fertilizers and sustainably achieve higher crop yields, improve soil fertility, alleviate soil acidification problems, and increase nutrient-use efficiency compared with only using chemical fertilizers. Crop yield can be increased through temporal diversity using crop rotation strategies compared with continuous cropping and legume-based cropping systems can reduce carbon and nitrogen losses. Crop yield responses to N fertilization can vary significantly from year to year due to variation in weather conditions and indigenous N supply, thus the commonly adopted prescriptive approach to N management needs to be replaced by a responsive in-season management approach based on diagnosis of crop growth, N status and demand. A crop sensor-based in-season site-specific N mana...
