As a controlled release N source, PSCU has the potential to increase total and marketable tuber yields with a single pre-plant application compared to urea source. However, there are still risks of leaching urea-N from a PSCU after the first few leaching events in sandy soils. Heavy early-season rainfall can deplete available soil N; thereby side-dress fertilizers might be still required to produce optimum tuber yields for both PSCU and urea treatments. Besides leaching, urea and urea-based… CONTINUE READING
