Title: STUDIES ON PHOSPHOROUS CHARACTERISTICS OF COMPONENT, ABSORPTION AND DESORPTION OF SHAJIANG BLACK SOILS IN THE SOUTH AREA OF SHANDONG PROVINCE
Abstract: The forms, composition, absorption and desorption of phosphorus of shajiang black soils were studied. The results showed: In the shajiang black soils, total content of organic phosphorus became higher with the increase of the fertility level of soils. Morderately active organic phosphorus and moderately stable organic phosphorus were dominantly involved, which were 83%~95% of the total organic phosphorus. In the shajing black soils, the content of apatite was 21%~55% of the total inorganic phosphorus, and that of accumulated phosphorus was 22%~47% of the total inorganic phosphorus. The content of absorption phosphorus of the shajiang black soils was comparatively high and became lower with the increase of the fertility level of soils, while the content of desorption phosphorus became higher.
