Abstract
Despite the benefits of no-till practices, soil compaction is a problem that can cause, among other things, mechanical impediment to root growth and less response to soil fertilization. The objective of this study was to evaluate the effect of subsoiling and doses of phosphate fertilization on soybean that have been cultivated over ten years under no-till systems in the Brazilian Cerrado. The experiment consisted of a randomized complete block design in a 2 × 4 factorial arrangement. Two managements in consolidated no-tillage area were considered: with and without subsoiling, along with four levels of phosphate fertilization: 0, 100, 300 and 400 kg ha-1 of P2O5. The practice of subsoiling in an area with ten years of no-till system provided an increase of 124.38 kg ha-1 in soybean productivity. Soybean plants grown under no-tillage system, with subsoil management, showed better development and pod production. The maximum phosphorus efficiency, with subsoiling, was achieved with the dose of 172 kg ha-1 of P2O5, yielding 5,693.4 kg ha-1. In the no-tillage system, the maximum efficiency dose and crop yield were 159 kg ha-1 of P2O5 and 5434.2 kg ha-1, respectively.
