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 ...
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&#...
In Brazil, there are extensive areas of degraded pastures. It is necessary to establish degradation levels using quality indicators for different biomes and regions. It is also essential that the evaluation of degradation levels be easily measurable. The objective of this study was ...
The Class A Pan is widely used for estimating reference evapotranspiration (ETo), a key parameter in irrigation management. Traditionally, water level readings are taken using a micrometric screw, which requires daily manual collection and is prone to operational errors. This study proposes&...
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 fertili...
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 indica...
Identifying practical, low-cost indicators for diagnosing pasture degradation is crucial for the sustainability of Brazilian livestock farming. This challenge is especially relevant in humid tropical regions, such as Cachoeiras de Macacu, RJ, where extensive livestock farming occurs in hillside areas&...
This study evaluates the feasibility of the commercial sensor S5-E200 as an alternative to the traditional micrometric screw used in Class A evaporation pans for estimating reference evapotranspiration (ETo). Commonly employed in fuel tanks, the sensor was coupled to an Arduino microcontroll...
A adoção de plantios mistos de eucalipto com espécies fixadoras de nitrogênio é uma prática que visa reduzir o uso de fertilizantes e melhorar a qualidade do solo através do sequestro de carbono orgânico no solo (COS). O objetivo do estudo foi avaliar o efeito de pla...
A principal fonte de nitrogênio utilizada em plantios florestais no Brasil é a ureia, que apresenta vantagens pela alta concentração de nitrogênio (N) e o menor preço por unidade de produto. No entanto, essa utilização está fortemente ligada as emissões de óxido nitroso (N2O). ...
