Effects of pasture practices on root distribution
1943
Haynes, J.L.
A study of root growth of pastures as affected by management and treatment practices is reported. An increase of roots near the surface and decrease of roots below 2 inches was associated with surface fertility application. Positive correlations were found between potash and root growth at low potash concentrations and between root growth and phosphate at high phosphate concentrations. As evidenced by effect upon root growth, continuous moderate grazing of nitrogen-fertilized pastures did not prevent carbohydrate storage during the summer grazing season under conditions of the study. The significance of an increase in root concentration near the soil surface in relation the control of erosions is noted.
