Influência de doses de calcário na produtividade e nas propriedades químicas do solo cultivado com soja

Abstract

Soybean (Glycine max) is a crop of great importance to global agriculture, especially in Brazil, where it faces the challenge of being cultivated in acidic soils. This study aimed to evaluate the influence of different lime doses on soybean productivity and soil chemical properties at Fazenda Girassol, located in the municipality of Ribeirãozinho in the state of Mato Grosso. The research was justified by the need to define management practices that optimize acidity correction without compromising the absorption of essential nutrients. The experiment was conducted using a strip design, with six lime doses applied to raise base saturation to different levels, and productivity was analyzed through linear regression and statistical tests. The results indicated that intermediate doses of lime effectively increased pH and improved calcium and magnesium availability. It was concluded that balanced lime management is important to improve soil chemical quality and optimize soybean productivity in acidic soils, highlighting the importance of a detailed soil analysis to determine the ideal dose.
