Abstract
La presente investigación tiene como objetivo principal determinar y cuantificar las
formas químicas de fósforo con el propósito de incrementar la productividad y
sostenibilidad de los dos suelos en estudio (andisoles y molisoles).
Para cumplir con este objetivo se seleccionaron 24 parcelas sometidas a tres
sistemas de cultivo: papa-intensivo, papa-pasto y rotaciones en las tres provincias
de influencia del proyecto. Posteriormente se procedió a realizar la extracción y el
fraccionamiento del fósforo total del suelo utilizando como extractante bicarbonato
de sodio.
The present investigation has as an main objective to determine and to quantify the chemical forms of match for the purpose of increasing the productivity and sustainability of the two soils in study (andisoles and molisoles). For complying with this objective twenty plots were selected submitted to three systems of cultivation: pope-intensive, pope- grazing and rotations in the three provinces of influence of the project. Subsequently it proceeded to carry out the extraction and the división of the whole match of the floor utilizing like extractante bicarbonate of sodium.
