Toxic Factors In Acid Soils Of The Southeastern United States As Related To The Response Of Alfalfa To Lime PDF Download

Excerpt from Toxic Factors in Acid Soils of the Southeastern United States as Related to the Response of Alfalfa to Lime: Production Research Report No. 80 Alfalfa plants on unlimed Rains soil showed some leaf marginal chlorosis that resembles manganese toxicity and also a stunting of growth, which is characteristic of aluminum injury. Although the manganese contents of plants were decreased with increased lime rates, the highest manganese content was probably too low to cause toxicity (appendix table Results of plant analyses suggest that calcium deficiency limited growth on the unlimed soil. Lime response was associated with a doub-ling of the calcium concentrations of plants. Yield increases obtained with lime were also related in a general way to decreases in extractable aluminum in soils. Mathers and Coleman (18) have concluded that low cal oium and aluminum toxicity limit plant growth on this soil.
