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 ...

Soil compaction, often the result of intensive mechanization, is a major concern because it increases the bulk density of the soil, fundamentally altering its structure and reducing its capacity to support essential ecological and agricultural functions. Therefore, soil monitoring is essential,&#...

O Jardim Botânico do Rio de Janeiro (JBRJ) constitui um importante espaço de conservação ambiental em meio a urbanizada cidade do Rio de Janeiro. Este trabalho teve como objetivo avaliar o balanço hídrico e estimar os serviços ambientais de regulação hídrica fornecidos pelo JBRJ.&#...

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 ...

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 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...

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...
