Avaliação da fertilidade dos solos em área de assentamento no município de Marabá

Abstract

Soil fertility is one of the most important factors for agricultural productivity. Soils in the state of Pará have serious fertility limitations that can hinder or restrict production on family farms. The objective was to evaluate the soil quality in settlement areas in the municipality of Marabá in relation to the physical and chemical attributes of the soil. 53 samples were collected at a depth of 0 to 0.2 m. The collected samples were analyzed in relation to the exchangeable contents of Ca+2, Mg+2 and K+, the available contents of P, organic matter (OM), were also determined. pH and Al+. With these results, the sum of bases, base saturation, effective and potential cation exchange capacity were calculated. The results show that in general The results showed average content of Ca classified in low range, average content of Mg, sum of bases, base saturation, effective CTC, potential CTC, P, Al and Ph classified in medium range and high range the average content of MO and K was found. In short, the data presented corroborate in parts with studies from the areas of Pará, showing the average content of calcium that differed from the others being in the lower class, highlighting the need to adopt strategies for soil management and conservation.
