Effect of heat on moisture retention in a pine (Pinus radiata) covered soil in Cajamarca, Peru

Abstract

The research was carried out on the soil covered by Pine (Pinus radiata) of the pine plantations of Granja Porcón, Cajamarca, the objective was: Determine the effect of heat on the physical-chemical properties of the soil covered by pine in Cajamarca and determine the effect of heat on the moisture retention of a soil covered with pine in Cajamarca. The results were the following: The granulometric fractions and textural class of the soil affected by heat have registered strong variations; The chemical properties that have registered an increase with increasing heat are: pH, EC, available P, base saturation; The chemical properties that have registered a decrease are: Al, MO, Nt, available K, change acidity. In normal soil subjected to 100 °C, the available water is 10.738 %, however, at 1000 °C, the amount of available water is 4.537 %; that is, it has decreased by 57.75 %.
