DEJETO SÓLIDO SUÍNO NO MANEJO QUÍMICO E BIOLÓGICO DO SOLO

Abstract

Increasing productivity is a growing demand, so it is necessary to find alternative solutions for inputs that may be lacking on the market, as well as studying ways of improving existing biological parameters. The experiment was carried out at Grupo Nova Terra - Bioativação Agrícola, located in the municipality of Rio Verde - GO specifically, at coordinates: 17° 45' 33''S, 50°41'00''W, altitude 742 m. Planting took place on November 8, 2021 using a randomized complete block experimental design, with 12 treatments distributed over 4 blocks. The treatments consisted of a control plot, complete chemical fertilization, isolated application of DSS at doses of 1, 2, 4, 8 and 16 tons ha-1 and the combined use of the same doses of DSS + fertilization. After harvesting and collecting the soil, laboratory and statistical analyses were carried out and it was found that the types of fertilization influenced the β-glucosidase levels. Chemical fertilization affected the activity of the β-glucosidase enzyme. The DSS + chemical fertilization interaction was significant for the potassium (K) content in the soil. Chemical fertilization influenced phosphorus (P) and potassium (K) content.
