THE EFFECTS OF GYPSUM ON THE CHEMICAL PROPERTIES OF OXISOL IN THE AMAZON SAVANNAH

The majority of soils in the Amazon savannah have low natural fertility, with issues of high acidity and high Al3+ saturation that restricts root growth. Lime is an alternative for soil correction, but its effects are limited to the soil surface. In contrast, gypsum acts in the subsurface, reducing...

description The majority of soils in the Amazon savannah have low natural fertility, with issues of high acidity and high Al3+ saturation that restricts root growth. Lime is an alternative for soil correction, but its effects are limited to the soil surface. In contrast, gypsum acts in the subsurface, reducing the activity of Al3+. This study aimed to assess the impact of different surface gypsum rates on the distribution of the root system, soybean nutrition, and the chemical improvement of Xanthic Haplustox in the Amazon savannah. A study evaluated the effects of different gypsum rates (0, 1.5, 3, 6, and 12 t ha-1) on the BRS 8381 soybean cultivar in a no-till system. Leaf analyses were performed to determine nutrient contents and vegetative production analyses were conducted. Trenches were also opened to analyze the root system visually. The application of gypsum increased the foliar contents of nitrogen, sulfur, and zinc while decreasing magnesium in soybeans. Although it did not affect grain yield, it improved the chemical environment, particularly during periods of water deficit, by enhancing the distribution of the soybean root system in Xanthic Haplustox in the Amazon savannah.
