Abstract
Sugar cane straw and/or P-fertilizer phosphorus-32 labelled were added to a Red Yellow podzolic soil from Goiana-PE. The treated samples were used in a pot experiment, growing sorghum plants for 4 and 6 weeks, and in an incubation experiment with incubation periods of 1, 2, 3, 4 and 6 weeks without plants in order to follow the dynamics of the P added. After each harvest and incubation period the soil were analysed for {sup 31} P and {sup 32} P in the microbial biomass and in sequential extracts with resin (Pi), 0.5 M Na H Co{sub 3} (Pi, Po) and 0.1 N NaOH (Pi, Po). The {sup 31} P and {sup 32} P contents of the sorghum in the pot experiment were also determined. (author).
