How phosphate is mined and processed

phosphorus is often the limiting nutrient; the amount of available phosphorus determines the amount of plant growth and development. Where phosphorus is plentiful, plants thrive, and vice versa. However, plants cannot absorb limitless amounts of phosphorus. Phosphorus not used by plants remains in the soil or runs off in streams and groundwater.

Organic Phosphorus Fertilizers, Organic Phosphorus Sources ...

Organic phosphorus fertilizers come primarily from mineral sources, like rock dust or colloidal phosphate (also called "soft phosphate"), or from bone sources, such as steamed bone meal or fish bone meal. Mineral phosphorus sources are cheaper and last longer in the soil. Bone sources are more readily absorbed by plants.
