This investigation is being conducted on three different soil typos. A composite soil sample was collected from each soil type. This sample was dried and ground. A sub-sample of each was then supplied to five different labs (two University & three private). A NPK recommendation for two-bale cotton was requested. Input costs, net and total returns to producers are being compared.
