Fire Does Not Reduce the Nutrient Value of Phosphorus Fertilizers
Fire strikes many fields in the Cerrado region of Brazil every winter due to weather conditions of high temperatures and low humidity. Some fires happen accidentally or farmers intentionally burn cover crops, crop residues, and pastures. Farmers wondered if the fire had an effect on their fertilizer, or if reapplication was needed so a partnership with IPNI and local researchers was established to investigate the effect of high temperatures on two common P fertilizers, single superphosphate (SSP) and triple superphosphate (TSP).
