Abstract
A dense, 5 cm plow pan is commonly found on Plainfield loamy sands in Wisconsin. Measurements have shown that when potatoes are grown on these soils, little root growth exists below the plow layer. To determine if rooting below the plow layer is restricted by the plow pan, soil was plowed with a moldboard “breaker” plow to 40 cm, 12 cm below the plow pan. No significant increase in the root density below the conventional plow layer resulted from destroying the pan.
Resumen
En Suelos franco-arenosos de Plainfield, Wisconsin, se forma comunmente un pan denso de 5 cm de grosor. De acuerdo a datos tornados cuando las papas son cultivades en esos suelos, se he encontrado que hay un crecimiento muy reducido de raíces debajo de la capa arable. Para determinar si el enraizamiento bajo la capa arable es restringido por la presencia del pan, el suelo fue arado profundamente con un arado subsolador a 40 cm; alcanzando hasta 12 cm bajo el pan. No se encontró aumento significativo en densidad de raices debajo de la capa arable que pudiera atribuirse a la destructión del pan.
