ANÁLISES QUÍMICAS DE SOLO EM DIFERENTES SISTEMAS DE ILPF

Abstract

Faced with a growing demand for food, the adoption of sustainable production systems is a pressing need. Among these systems, Crop-Livestock-Forest Integration (CLFI) and Crop-Livestock Integration (CLI) have stood out in recent years. The aim of this work was to analyze the chemical attributes of a Cambissolo, located on the soil of the IF Goiano School Farm - Campus Iporá, under the ILP and ILPF systems. The experimental design was entirely randomized (DIC) with five replications, with four ILPF systems with different forest components: T1 (Angico), T2 (Baru), T3 (Eucalyptus Clone I144) and T4 (Eucalyptus Clone VM 01), as well as two monocultures (corn and soybeans). The data was evaluated using Student's t-test at a 5% significance level. Regardless of the forest component, the ILPF system was more promising in improving soil fertility levels, providing higher values for calcium, magnesium, CTC, copper and manganese. As for the forestry components, the ILPF system with Clone VM01 eucalyptus showed better fertility conditions, with higher levels of the nutrients calcium, magnesium, potassium, CTC, manganese, phosphorus and lower aluminum toxicity. The analyses also revealed significant differences in micronutrients between soybeans and corn. The conclusion is that pH and acidity correction practices are essential to optimize soil fertility and guarantee plant development and productivity.
