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/1183856 Título: Analysis of the competitiveness of fruit exports from Minas Gerais (2012-2022). Autoria: MOREIRA, A. C. S. D.; DONAGEMMA, G. K. Conteúdo: This study evaluated the competitiveness of fruit exports from Minas Gerais, Brazil, between 2012 and 2022, compared to other Brazilian states. The focus was on transaction dimensions (asset specificity, uncertainty, and frequency) and governance structure. The methodology employed two key indicators to measure performance: Market Share (MS), which reflects the proportion of a region’s exports relative to the national total, and Revealed Comparative Advantage (RCA), which identifies sectors where a region has a relative export advantage. It was observed that Minas Gerais fruit exports, although growing, remain insignificant in the national scenario, representing a small portion of the Brazilian total, despite the state being the fourth largest national fruit producer. The main difficulties identified include logistical bottlenecks, quality issues, and the concentration of production in a limited number of products. The practice of product triangulation, where exports are registered in other states, distorts Minas Gerais’ real data, masking its contribution and comparative advantage. Sustainability in Minas Gerais’ fruit export sector is driven by the adoption of technological innovations, such as genetic improvement, integrated pest and disease management, and soil and water conservation practices, which are crucial for differentiation in the international market. It is concluded that Minas Gerais faces structural and coordination challenges that limit its full insertion and competitiveness in the global fruit trade. The unification of fruit growers and the implementation of incentive policies are essential to overcome these obstacles and consolidate the state’s position in the international market. 2025-01-01T00:00:00Z
