Effects of phosphorus and organic fertilizers on phosphorus fractions in submerged soil

Effects of phosphorus and organic fertilizers on phosphorus fractions in submerged soil

This study was conducted in order to evaluate effects of phosphorous fertilizer (PF)s from sources of triple superphosphate (TSP) and di-ammonium phosphate (DAP) and organic fertilizer (OF)s from sources of cow dung manure (CDM) and municipal solid waste compost (MSWC) on phosphorous (P) fractions i...
