Effect of agronomic practices in soil properties in hillsides.

Trials were established in a highly eroded Ultisol soil of sandy loam texture, of poor fertility, acid, and low in phosphorus and organic matter, located in the locality of La Leña in Pinar del Río province, Republic of Cuba. A study was carried ont in 1996 in two watersheds, in which were implement...

A study was carried ont in 1996 in two watersheds, in which were implemented conservation practices consisting of live barriers of Gliricidia Sepium L. (in the first watershed) and Vetiveria Ziznoide L. (in the second watershed) complemented with ground cover of maize associated with legumes followed by beans in succession. Results showed slight changes in slope between barriers with respect to the initial value (10% vs 9%). Values of total dry biomass in the associations were 17 and 15 t/ha, and ground coverage at 30 days was more than 70%. Profuse root colonization presented by the associations indicated an improvement in porosity of the soil, reflecting a positive tendency in the internal structure that has evolved to a porous state. Yields of maize were 2900 and 2000 kg/ha, and of bean were 1800 and 1630 kg/ha, which are relatively high values, considering the degraded condition of the soil.En un suelo Ultisol de textura arenosa, fuertemente erosionado, de baja fertilidad en fósforo, materia orgánica y ácido, ubicado en la localidad de La Leña en la provincia de Pinar del Río, en la República de Cuba, se realizó durante el año 1996 un ensayo en dos segmentos de microcuencas, en las que se implementaron medidas de conservación de suelos consistentes en barreras vivas de Gliricidia sepium L. (primer segmento) y Vetiveria zizanoide L. (segundo segmento) complementadas con coberturas de maíz asociado con Mucuna d. y Canavalia e., como precedentes del Frijol. Los resultados mostraron ligeros cambios de la pendiente intrabarreras con respecto al valor inicial (10 y 9%). Los valores de la biomasa seca total de las asociaciones fueron de 17 y 15 t/ha, la velocidad de cubrimiento a los 30 días fue mayor al 70%, la colonización radical profusa presentada por las asociaciones indican una mejora de la red poral del suelo, reflejándose en la tendencia positiva del estado interno de la estructura que evoluciona hacia un estado (G) poroso. Los rendimientos de maíz fueron de 2900 y 2500 kg/ha y los de frijol de 1800 y 1630 kg/ha.
