Abstract Subsoil acidity restricts root growth and reduces crop yields in many parts of the world. More than half of the fertilizer nitrogen (N) applied in crop production is currently lost to the environment. This study aimed to investigate the effect of gypsum application on the efficiency of N fertilizer in no-till corn ( Zea mays L.) production in southern Brazil. A field experiment examined the effects of surface-applied gypsum (0, 5, 10, and 15 Mg ha −1 ) and top-dressed ammonium nitrate… CONTINUE READING
