In this study, novel technology was developed to convert dolomite phosphate rock (DPR) into slow release P fertilizers. The DPR was powdered to <100 mesh and activated with organic molecules under optimal reaction conditions. As compared to original DPR, available P, estimated by watersoluble P released from the three DPRs activated with three types of organic molecules, increased by, 3 ...

differences in phosphate rock availability have not been fully clarified. Investigations generally have shown that acid soils allow a more favorable response to phosphate rock than do neutral or alkaline soils. Also, it is known that the rel ative response depends upon the crop grown. For instance, lu pine and buckwheat are much more efficient than barley or wheat in utilizing .

· To make phosphorus available in alkaline soils rock phosphate is partially acidified with inorganic acids before appliion (2). This approach is not applied in organic agriculture as it involves the use of inorganic compounds. An approach more welcomed in organic farming is the integration of rock phosphate with compost or the integration of rock phosphate, compost and phosphate solubilising ...

Phosphate rock used for fertilizer is a major NORM due to both uranium and thorium. Phosphate is a common chemical constituent of fertilizer. It is principally mined from apatite and phosphate rocks (phosphorite) in which the concentration of phosphate has been enhanced by sedimentary, igneous, weathering, and biological processes.

In almost all cases, the phosphate rock must be ground to liberate the calcite and/or dolomite so that it can be separated from the phosphate rock. However, with the level of carbonate contamination typically found in Florida phosphate rock, this type of processing scheme has not been adopted. This is due primarily to problems associated with grinding and handling the ground rock at the mine.
