Manejo de solo pós cultivo florestal para a implantação de grandes culturas

Abstract

Soil is considered the main natural resource for the development of a plant, providing nutrients and conditions necessary for its growth. Its physical and chemical conditions can be improved through periodic soil analysis and conservation practices, seeking a soil-­plant-­environment balance. Thus, the objective of this work was to carry out a diagnosis of conservation practices of soil management after forestry cultivation for the implantation of large crops of agronomic interest. The experiment was carried out in a private area located in the municipality of Goioxim­PR. The work was divided into two stages, in the first, soil management and analysis was carried out after forest harvesting, and in the second, planting and soil analysis were carried out after agricultural planting. Initially, mapping of the area was carried out in order to plan the subsequent processes. Subsequently, soil management was carried out for the implantation of agricultural crops in a contour line with terracing for subsequent implementation of a crop rotation system. Finally, the physical and chemical analyzes were carried out: pH in water, phosphorus, potassium and sodium content, potential acidity and organic matter to correct fertility and liming after soil preparation and after planting the first crop inserted. The results showed improvements in all chemical variables analyzed after soil correction, but the results are still lower than desired, as the period between soil correction and the second analysis was very short. It is concluded that the planning and use of conservation management techniques for planting, combined with correct soil correction, can provide a chemically balanced environment for the insertion of agricultural crops.
