Soft Rock Phosphate is an important phosphate source that is actually a byproduct from the old time hard rock mining. In order to increase the purity of the higher analysis of the hard rock, the soft rock was a clay impurity which was washed and then it was sent in this water through to a settling pond.
Phosphate Rock is also often used in landscape and nursery applications to help plants adjust to the stress associated with transplanting. Phosphate Rock cannot burn roots like acidulated phosphate can, and liberal amounts can be applied directly to bare root stock.
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.
The term phosphate refers to any one of a wide variety of chemical compounds that contain phosphorus, a naturally occurring mineral, bonded together with oxygen. The term is used both in inorganic chemistry and organic chemistry. In inorganic chemistry, the phosphate ion combines one phosphorus atom with three or four oxygen atoms, forming the base for many different salts.
The element phosphorus is very important for many facets of life. Thus phosphate minerals in which phosphorus is oxidized in the phosphate group PO4 are part of a tight geochemical cycle that includes the biosphere, rather like the carbon cycle.

Jan 23, 2020· Flowers like roses love phosphate rock fertilizers as it helps them develop more buds and a stronger root system. The phosphates present in the formula are also used for a healthy lawn and tree root system development. It serves as an all-purpose fertilizer for different kinds of perennials and trees in the garden.
Like limestone, phosphate rock is deposited in sedimentary basins where the influx of detrital material is relatively low. That allows the phosphate to accumulate with very little dilution from other materials. Where the dilution rate is high, phosphatic shales, mudstones, limestones, and sandstones will form instead of phosphate rock.
The Mining Process. The mining process in Florida begins with a field study to determine the location and density of the phosphate deposits. Information like the location, size, and shape of the ore is determined to focus the mining effort.
Triple Superphosphate Triple superphosphate (TSP) was one of the first high-analysis phosphorus (P) fertilizers that became widely used in the 20th century. Technically, it is known as calcium dihydrogen phosphate and as monocalcium phosphate, [Ca(H₂PO₄)₂ .H₂O]. Despite its excellent history as a P source, its use has declined as other P fertilizers have become more popular.
