About one-and-a-half acres of tropical forest, of known mass and chemical composition, was cleared and burned. Soil changes during clearing and two years' cropping were studied. Following burning, approximately all the K, Ca, and Mg in the vegetation were accounted for by the rise in exchangeable K, Ca, and Mg in the soil. There was a marked rise in soil pH. A small but significant increase in C and N was attributed to admixture of parts of the vegetation with the soil. Following cultivation… CONTINUE READING
