Inclusión de cultivos de cobertura en monocultivo de soja:: un paso hacia el mejor aprovechamiento del agua pluvial
Cover crops (CC) improve the management of the hydric resources, because it determine the pick up, runoff,infiltration and evaporation rates. The objective of this work was to study how winter CC affect soil wateravailability and how this can be altered by the moment of death of CC. In Sub-humid reg...

| Sumario: | Cover crops (CC) improve the management of the hydric resources, because it determine the pick up, runoff,infiltration and evaporation rates. The objective of this work was to study how winter CC affect soil wateravailability and how this can be altered by the moment of death of CC. In Sub-humid region it were seedingthree winter CC and this were death in three moment, comparing the effect with traditional fallow. The CCreduce significantly soil water, but this it caused the soil surface protection against spring rains by producingbiomass. In general, soil water availability for soybean seeding was not affected. Traditional fallow lost thewater accumulated from autumn rains by direct evaporation and it was less efficient to catch sprig rains,because of this soil water at soybean seeding was until 30 mm less that observed for CC. |
