Abstract:

Application of organic fertilizers and charcoal increase nutrient stocks in the rooting zone of crops, reduce nutrient leaching and thus improve crop production on acid and highly weathered tropical soils. In a Weld trial near Manaus (Brazil) 15 diVerent amendment combinations based on equal amounts of carbon (C) applied through chicken manure (CM), compost, charcoal, and forest litter were tested during four cropping cycles with rice (Oryza sativa L.) and sorghum (Sorghum bicolor L.) in Wve replicates. CM amendments resulted in the highest (P < 0.05) cumulative crop yield (12.4 Mg ha
