Effect of Sulfur and Boron Fertilization on Alfalfa

Historically, sulfur (S) deficiency has not been an issue for crop production in Iowa. Research results as recent as 2002 on corn and soybeans were consistent with previous results. The exception was a long-standing suggestion to apply S as commercial fertilizer or livestock manure for alfalfa production on sandy soils.

Potato Response to Boron and Sulfur Fertilization

This trial was conducted to investigate how potatoes respond to boron and sulfur fertilization when grown on coarse sand soil with low organic matter.
