Possible Interaction: Phosphorus and Potassium

“Additionally, the magnitude of elevations in potassium and phosphorus concentrations appear to be related.”

“It also abolished the fall in plasma phosphorus but appeared (if anything) to augment the increase in potassium.”

“A significant correlation was observed between the phosphorus and potassium uptake of the aerial and underground parts, respectively (P < 0.05).”

“The response to lime also depended on the type of nitrogen applied; there was no relationship between lime treatment and species … sulfate, where species richness increased sharply with increasing soil pH. The addition of phosphorus reduced species richness, and application of potassium … phosphorus reduced species richness … were applied together.”

“The results indicated that application of nitrogen fertilizer accelerated a large deficit of soil phosphorus, and the use of nitrogen and phosphorus accelerated the deficit of potassium.”

“In a casein hydrolysate medium, potassium alone produced this effect; however, in a synthetic (amino acid) medium, phosphorus was found to cause a slight increase in yield of diol especially in the presence of potassium.”
