Zinc uptake by oats as influenced by application of lime and phosphate
1948
Rogers, L.H. | Wu, C.
A pot experiment was conducted with virgin Lakeland fine sand and Florida 167 variety of oats. Thirteen treatments were made, replicated four times, with varying lime, phosphate, and zinc applications to the soil. Average weights of two cuttings of the oats, as well as zinc and phosphorus contents, were determined. The zinc content of the plants decreased to an almost constant value with increasing rates of application of phosphate, while the phosphorus content increased regularly in diret ratio to that applied. Higher rates of application of phosphate resulted in significant increases in plant weights at the second cutting. The zinc content decreased with increasing rates of lime application but increase regularly with increasing zinc applications.
