Abstract

The soils physical quality is a determinant factor for the performance of grain crops. The objective of this work was to evaluate the influence of sources and doses of phosphorus on the physical attributes of a soil. The study was carried out in a clayey dystrophic Yellow Latosol in a randomized block design, in a 3x5 factorial scheme in three blocks, three sources (single superphosphate, triple superphosphate and Arad) and five doses (0, 60, 120, 180 and 240 kg ha-¹) of phosphorus. The following physical soil properties were determined: soil density (Ds), Total Porosity (PT), Gravimetric Humidity (UG), Particle Density (Dp) in three depths. The doses of phosphorus influenced the physical attributes of the soil Ds e PT.KEYWORDS: Phosphate fertilization, Physical properties, Soil management.
