Supplying Calcium and Magnesium for Cotton on Sandy, Low Cation Exchange Capacity Soils1
- G. D. McCart and
- E. J. Kamprath2
Results indicated that it would be desirable to lime sandy, low-CEC soils to a pH of 6.2–6.5 for optimum growth of cotton. The presence of soluble Al at pH levels of 5.5 and below appeared to be an important factor in reducing the growth of cotton. It was found that soil acidity had to first be reduced before cotton benefited from the presence of higher amounts of Ca in the soil. Additions of Mg SO4 at different pH levels did not increase growth of cotton.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
