Última Phosphorus analysis in soil under herbaceous perennial leguminous cover by nuclear magnetic spectroscopy PAB Canellas,Luciano Pasqualoto; Espíndola,José Antônio Azevedo; Guerra,José Guilherme Marinho; Teixeira,Marcelo Grandi; Velloso,Ary Carlos Xavier; Rumjanek,Victor Marcos. The availability and the reserves of organic phosphorus are controlled by its mineralization rate and are also influenced by changes in soil management. The objective of this study was to evaluate the influence of soil covering with different leguminous plant on soil organic P by 31P-NMR spectroscopy. Alkaline soil extracts were obtained from two depths (0-5 and 5-10 cm) of an Ultisol cultivated with herbaceous perennial leguminous plants (Arachis pintoi, Pueraria phaseoloides, Macroptilium atropurpureum). In an adjacent area, samples of the same soil cover with a secondary tropical forest and grass (Panicum maximum) were also collected. The leguminous management was divided into with removal and without removal of shoot parts after cut on soil surface....
