ABSTRACT: The use of mineral phosphate fertilizers associated with organic residues can improve fertilizer use efficiency and consequently decrease their usage costs. Soil application of filter cake (FC) can provide nutrients and enhance physical quality. This study aimed to evaluate the effects of different phosphate fertilizers [rock phosphate (RP) and triple superphosphate (TSP)] applied at different rates (90 and 180 kg ha-1 P2O5) associated with filter cake (10 Mg ha-1 dry matter) on the soil phosphorus (P) fractions after two […]

Soil cation availability as affected by the tillage system

Paulo Sergio Pavinato, Alexandre Merlin, Ciro Antonio Rosolem

01/Aug/2009

The management system normally affects soil nutrient availability, as a consequence of tillage practices, crop rotation and crop residues remaining in the cultivated area. The objective of this study was to evaluate the alterations in cation availability in two Oxisols in the Brazilian Cerrado under conventional and no-tillage systems for more than 10 years. The experiments were conducted in Costa Rica, state of Mato Grosso do Sul, and in Luziânia, Goiás. Both soils were Oxisols, but one being a Red Latosol […]

Effects of organic compounds produced by plants on soil nutrient availability

Paulo Sérgio Pavinato, Ciro Antonio Rosolem

01/Jun/2008

This review aimed to compile information on the effect of plant-produced organic compounds on soil nutrient availability, especially on the cations Ca, Mg and K, and on the anion phosphate. The tillage system alters the soil chemical and physical properties, especially the nutrient availability and soil physical conditions. Due to the absence of soil plowing and deposition of crop residue on the soil surface, nutrient accumulation has been observed in soil surface layers in the no-till system. Plant organic acids […]
