Title A name given to the resource Evaluación de seis abonos verdes en un vertisol ústico en condiciones del Valle del Cauca Creator An entity primarily responsible for making the resource Bonilla C. C. R., Sánchez M. S., Salamanca W. F. Description An account of the resource En el Centro Experimental de la Universidad Nacional de Colombia-Sede Palmira, en un diseño de bloques completos al azar, se evaluaron seis tratamientos con tres repeticiones. (Cajanus cajan guandul arbóreo y arbustivo; Canavalia ensiformis, fríjol Canavalia; Cynodon niemfuensis, pasto estrella; Zea mays, Maíz y Cucúrbita moschata, zapallo). El pasto estrella y el zapallo fueron cultivos previos al ensayo; los otros materiales se sembraron por semilla a 50 cm en cuadro y se incorporaron al suelo a los 150 días cuando se cosechó el maíz (choclo). Maíz y canavalia aportaron mayor biomasa al suelo (10.068 y 9.748 kg/ha, respectivamente). C. cajan arbóreo y C. ensiformis aportaron las mayores cantidades de nitrógeno (254 y 213 kg/ha). El maíz y el pasto estrella, por sus altos contenidos de lignina, se descompusieron más lentamente. En casi todos los tratamientos se presentó incremento de la población microbiana, predominando la población de bacterias, seguida por hongos, fijadores de nitrógeno de vida libre y luego la población de actinomicetos.&#13; &#13; ABSTRACT&#13; &#13; Evaluation of six green manure materials in a Ustic Vertisol Soil of Cauca Valley, Colombia. This research was realized in the Experimental Center of the National University in Palmira. A design of a Randomized Completed Blocks, with six treatments and three repeticions was used. The treatments were two accesions of guandul (tree and shrub) Cajanus cajan, Canavalia Canavalia ensiformis Corn Zea mays, Star grass Cynodon niemfuensis and Ramkin Cucúrbita moschata. The plot size was 20 m x 10 m. The materials were incorporated with tractor and disk plough when the maiz was colected as ear. The results showed that corn and Canavalia had the higher yields of fitomass (10068 and 9748 kg/ha, respectively). The legumes C. cajan (tree) and C. ensiformis showed higher yileds of Nitrogen (254 and 213 kg/ha) and biomolecules. Z. mays and C. nlemfuensis were the treatments with lower descomposition rate in the soil.&#13; &#13; Key words: green manure, fitomass, nutrients, Canavalia, Guandul, star grass, corn, soil microbiology.
