Impact of the contributions of organic amendments on the degraded sialitic brown soil physical properties

Abstract

The work was developed with the objective of evaluating the effect of the contribution of organic amendments filter cake, (16.4 and 20 t.ha-1), cattle manure (14.5 and 17.4t t.ha-1) and compost (28 ,2 and 34.0 t.ha-1) on the physical properties of a degraded Sialitic Brown soil. Plots of 20 m2 were established where the different treatments were located plus a control treatment, distributed in random blocks with three replicates. indicators apparent density (g.cm-3), resistance to penetration (kg.cm-3) and infiltration rate (cm.h-1) A positive effect of the organic amendments on the physical indicators studied was observed, by reduce compaction in the first 20 cm The lower doses of cattle manure and compost show the lowest values of resistance to penetration and apparent density, while the infiltration of water into the soil was favored by the dose of 20 t. ha-1 of filter cake.
