Hu et al (1996) The effect of direct application of phosphate rock on increasing crop yield and improving properties of red soil. The commercial rock phosphate fertilizers are commonly known as rock dust. In addition to rock phosphate, many gardeners also swear by the benefits of Azomite and bone meal for replenishing soil phosphorus. This is the result of a higher concentration of carbohydrates in plants. You can also use bones (such as from your kitchen,) if you have them in sufficient amounts.

However, most of them now use the processed rock phosphate fertilizers available on the market due to the lack of supply of rock phosphate and its low concentration of phosphorus. One of the most common signs of phosphorus over-fertilization is the yellowing of leaves between the veins. Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals.The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P 2 O 5).Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O 5.

Espoma Rock Phosphate is an all natural mineral that has been pelletized to minimize dust and add convenience. When supplemented with rock phosphate, rose plants not only develop strong roots systems and exhibit healthier overall growth but also produce more flowers. In general, rock phosphate works the best in acidic soils. Nisha et al (2014) Role of phosphorous solubilizing microorganisms to eradicate P- deficiency in plants: A review. Fertoz’ extensive research led to rock phosphate ore sources that are high in total and available phosphorus in favourable geographic locations. PhD thesis, University Of Agriculture, Faisalabad. Since phosphorus is largely soluble in acidic soils, it becomes more accessible for plants and hence, easily and more readily absorbed by roots. As a natural source of phosphorus, it avoids the use of inorganic fertilizers which contribute to green house gas emission during its manufacturing process. However, perennial flowering plants benefit the most from the use of phosphate rock as it encourages more and healthier blooms. This happens because when present in too much quantity, phosphorus makes zinc, iron, and manganese unavailable to plants. Roses, in particular, love rock dust application. In some parts of the world, phosphate rock is also used to make calcium phosphate nutritional supplements for animals.
