摘要: Abstract Patterns of N mineralization and P release were determined in two characteristic soils the Andean-Patagonian Region (Andisol) transitional zone to steppe (xeric Mollisol) amended with fish residues biosolids. Residues applied at rates 10–20 g kg-1 incubated for 112 d under controlled temperature soil moisture conditions using a non-leaching procedure. Nitrogen mineralized from total added depended mainly on type residues, while firstly type, secondly residue type. Fish displayed potential as slow-release fertilizers, biosolids showed marked initial flush N. Due high content, might exert adverse environmental agronomic effects xeric Mollisol when meet crop requirements. In Andisol retention capacity, would cover both Nand Biosolids unable to...
