Autoria: BENITES, V. de M. Conteúdo: O Brasil é o quarto maior consumidor de fertilizantes do mundo, atrás apenas dos EUA, China e Índia. A cultura da soja é o carro chefe do consumo de fertilizantes no Brasil, sendo responsável por cerca de 35 % do total de fertilizantes consumidos (ANDA, 2010). A forte dependência por fertilizantes pela cultura da soja em solos brasileiros está relacionada à baixa fertilidade natural dos solos aonde essa planta é cultivada. Nas principais áreas de produção de soja no Brasil, predominam os Latossolos, que são solos que normalmente apresentam boa condição física, porém são naturalmente pobres em nutrientes em função dos fatores de formação desses solos. 2012-01-01T00:00:00Z https://www.alice.cnptia.embrapa.br/alice/handle/doc/1184209 Título: Avaliação fitossanitária em pomares de uva (Vitis spp.) na Zona da Mata de Pernambuco. Autoria: FARIAS, J. S. de; PEREIRA, A. P. da S.; SANTOS, T. C. G. dos; ANDRADE, G. P. de; PIO-RIBEIRO, G.; TAVARES, S. C. C. de H. Conteúdo: Visando a minimização de problemas fitossanitários e de impactos negativos ao ambiente, o presente trabalho realizou o monitoramento da incidência das doenças e pragas em videiras de pomares comerciais, localizadas no município de São Vicente Férrer da Zona da Mata de Pernambuco, a fim de observar nesta nova investigação se houve ou não redução de aplicações de agrotóxicos. 2010-01-01T00:00:00Z https://www.alice.cnptia.embrapa.br/alice/handle/doc/1183850 Título: Advances and potential applications of biochar-based organomineral fertilizers to improve nitrogen use efficiency. Autoria: MARQUES, A. K. M.; CARMO, D. de F. do; VEZZONE, M.; CAMPOS, D. V. B. de Conteúdo: Nitrogen (N) is an essential nutrient for plant growth, but its use efficiency (UNE) is often limited by losses due to leaching, NH volatilization, and denitrification, impacting both productivity and the environment. Factors such as fertilizer type, soil characteristics, climate, and crop directly influence UUE, with sandy tropical soils being particularly susceptible to N losses. Biochar derived from organic waste has proven effective in mitigating these losses, acting as a soil conditioner, increasing pH, moisture retention, porosity, and microbial activity, favoring greater N absorption by plants. This review summarizes recent evidence on the role of biochar in improving ENU, reducing N losses, and enabling innovative fertilizer formulations. Studies indicate that biochar modified or used as a coating for urea, as well as organomineral fertilizers, promotes the gradual release of N, increases macroaggregate stability, reduces leaching and gaseous emissions, and increases productivity. In addition, innovative formulations incorporating lauric acid or Hermetia illucens by-products increase the multifunctionality of biofertilizers and contribute to circular economy practices. These strategies link nutrient management to waste valorization, contributing to more sustainable fertilization approaches. 2025-01-01T00:00:00Z https://www.alice.cnptia.embrapa.br/alice/handle/doc/1183862 Título: Initial corn growth in pots fertilized with organomineral fertilizers made from dehydrated poultry manure. Autoria: LIMA, F. L. de O.; CAMPOS, D. V. B. de; SOUZA, K. A. M. de; ARAUJO, E. da S.; CARMO, D. de F. do Conteúdo: Brazil is the second-largest producer of chicken meat globally, generating substantial amounts of manure with potential environmental impacts if inadequately managed. Dehydrated chicken manure can be a technique used to reduce volume, lower emissions, and increases shelf life however, its fertilization efficiency can be lower than that of mineral fertilizers. This study aimed to develop organomineral fertilizers combining dehydrated manure with mineral nutrients and to evaluate their effectiveness in supplying potassium (K) relative to KCl and K2SO 4. Five NPK formulations were applied to nutrient-poor sandy soil in a greenhouse experiment using corn as an indicator crop. The aboveground biomass was harvested, dried, and weighed to assess dry matter production and agronomic efficiency. All fertilized treatments enhanced growth compared to the control. T1 achieved the highest dry matter (6.48 g·pot ¹) and agronomic efficiency (49.40%), followed by T5 (5.89 g·pot ¹, 43.48%), whereas T3 exhibited the lowest efficiency (10.78%). The results indicate that the organomineral formulations can viable alternatives in supplying K to corn. 2025-01-01T00:00:00Z
