The Effect of Various Fertilizers on the Botanical Composition and Yield of Grass‐Legume Hay¹

Continuation of Long‐Time Field Experiments by Transference to Cement Frames1

“…Where sufficient lime was applied, sulfate of ammonia was the better source of nitrogen for potatoes. Similar results were obtained on the corresponding fie] d plots ( 10). In the case of corn, liming was more important than the source of nitrogen.…”

Fertilizer Effects on Botanical and Chemical Composition of White Clover‐Dallisgrass Associations Grown on Sumter Clay1

“…In earlier studies Rich and Odland ( 6) reported that a reduction in potash fertilization lowered the proportion of legumes in grass-legume hay. However, Brown (2) reported that potash added to either superphosphate or superphosphate and limestone did not greatly affect the amount of white clover in a clover-grass sod.…”

Effects of Phosphorus and Potassium Fertilizers on Legume Composition of Seven Grass‐Legume Mixtures

“…Rich and Odland ( 9) found potash to have a very pronounced effect on both yield and the percent legume in the mixture. Reducing the potash level from 100 to 50 pounds lowered the proportion of legumes from 50 to 3% and hay yield from 3.08 to 1.63 tons per acre.…”
