We will never recommend fertilizer rates at a local level. There are way too many variables that we do not know about. We leave the fertilizer rate recommendation conversation to the local agronomist. Our studies show that a full P rate treated with Avail T5 will give the grower the highest ROI. However, if you are in a situation where reduction of rates is a must (high P prices, lack of P supply, regulations etc.) Avail T5 WILL help the grower maximize their fertilizer investment.
