The Influences of Magnesium upon Calcium Phosphate Mineral

Calcium phosphate minerals are typically the solubility-limiting phase for phosphate in calcareous soils. Magnesium (Mg) despite being present in high concentrations in calcareous soils has been largely neglected in the study of formation and stabilization of soil phosphate minerals due to the high solubility of pure Mg phosphate phases. In this study a series of four common calcium and

Chemical precipitate clogging caused by injected

Injecting many fertilizers that contain phosphorus may cause a reaction with calcium and magnesium in the irrigation water causing phosphate precipitates to form if the calcium or magnesium concentrations are higher than 2.5 meq/l or 40 to 50 ppm. These precipitates can be difficult to dissolve out of emitters.

Magnesium Impact Fertilisers

Magnesium and nitrogen are the only soil absorbed plant nutrients that are components of chlorophyll. When magnesium is in short supply plant growth will be reduced and potentially yield will be limited. Many soils contain sufficient magnesium however high yielding horticultural crops often have additional magnesium supplied to meet plant demands.

Mitigation of Cd accumulation in rice with water

The treatment of calcium-magnesium phosphate fertilizer and continuous flooding has reduced available content of Cd in soils by 28.57 . The content of Cd in brown rice was significantly diminished by 51.36 (P < 0.05). The continuous flooding has promoted formation of residual Cd in soil with application of calcium-magnesium phosphate fertilizer.
