Effects of ammonium lignosulphonate and diammonium phosphate on soil organic carbon, soil phosphorus fractions and phosphorus uptake by corn

Abstract

Lignosulphonate (LS), a by-product of the pulp and paper industry, could have beneficial effects on fertilizer P. Effects of ammonium lignosulphonate (ALS) and diammonium phosphate (DAP) on corn (Zea mays L.) P uptake, extractable P and P fractions were measured. Soil organic C increased with increasing ALS addition and decreased with DAP additions. ALS had little effect on native soil P fractions. -from Authors
