2016-12-2  In the phosphate industry, the phosphate content of the rock is usually expressed as tricalcium phosphate and traditionally referred to as bone phosphate of lime (P2O5 × 2.1853 = BPL). The latter term is reminiscent of the time when bones were the principal source of phosphate in the fertilizer industry. Manufacturers of phosphoric acid

Introduction to the Chemistry of Fertilizers

phorus which can be used by plants is designated as bone phosphate instead of phosphoric acid. The bone phosphate content is roughly twice that of the phosphoric acid content, so that when the bene phosphate figure is given one can convert it to approximate terms of phosphoric acid simply by dividing by two. Many of the other

Phosphoric acid is supplied in the form of phosphates of lime, iron, and alumina. Some of the materials used are bone phosphate (phosphate of lime), raw bone, bone meal, steamed bone, bone black or animal charcoal, bone ash, South Carolina, Florida, Canada and Tennessee rock phosphates, iron phosphate, a by-product of the manufacture of iron phosphatic iron ores, and superphosphates (a product

Understanding phosphorus fertilizers UMN Extension

2021-5-23  Rock phosphate is the raw material used to manufacture most commercial phosphate fertilizers on the market. In the past, ground rock phosphate itself has been used as a source of P for acid soils. However, very little rock phosphate is currently used in agriculture due to low availability of P in this native material, high transportation costs

Rock Phosphate Fertilizer Garden Myths

Rock phosphate is accepted in the NOP because it is not synthetic and has not been treated by acids as in super phosphate and other more available forms. Gardeners would not use rock phosphate because at the scale at which most people garden, they can get their phosphorus from compost or bagged fertilizer

Discussion 62 Determination of phosphorus in fertilizers

2016-5-17  In about 1840, Liebig proposed treating bone phosphate with sulphuric acid to increase the availability of P to plants. However, the conversion of insoluble hard rock phosphate to soluble superphosphate by treatment with sulphuric acid was patented in 1842 by Sir John Bennet Lawes, who opened the world's first artificial fertilizer factory the
