Zaria, Nigeria during 2015 and 2016 wet seasons to investigate the effect of phosphorus levels on the growth and yield of cowpea (SAMPEA 17). The treatments consisted of five levels of phosphorus (0, 10, 19, 29 and 39 kgPha-1) in the form of single superphosphate laid out in randomized complete block design (RCBD) and replicated four times.

Phosphorus fertilizers are manufactured from rock phosphate (Figure 2.2 ), but rock phosphate itself seldom is used directly as a fertilizer because of its low availability of phosphorus and transport cost. Instead, finely ground rock phosphate is treated with sulfuric acid to yield monocalcium phosphate monohydrate and is known as superphosphate.

Morocco remains the largest exporter of phosphate. However, the high cost of mining and threats of war has derailed the production of phosphate in the country. Chin is a distant second with 5% of the total reserves, translating to approximately 3.1 billion tons. However, China remains the largest producer of phosphate at 138 million metric tons.

Background: The Niger Delta region of Nigeria has a high concentration of companies using organo-phosphorus compounds with workers who have been exposed to these compounds for varying lengths of time resulting in toxic manifestations in some of the workers. Studies have revealed that plasma cholinesterase and red cell cholinesterase levels are reduced following organo-phosphorus toxicity.

Phosphorus is a chemical element found on Earth in numerous compound forms, such as the phosphate ion (PO43-), located in water, soil and sediments. The quantities of phosphorus in soil are generally small, and this often limits plant growth. That is why people often apply phosphate fertilisers on farmland. Animals absorb phosphates by eating plants or plant-eating animals.

The phosphorus in precipitation provides a significant fraction of the bioavailable phosphorus to fresh and marine waters. To identify the possible sources and interpret the atmospheric deposition processes of phosphorus, we measured the phosphate oxygen isotopes (δ 18 O P) in the precipitation monthly from October 2015 to March 2017 in Daya Bay, South China Sea.

Phosphorus found in animal foods is absorbed more easily than phosphorus found in plant foods. Phosphorus that has been added to food in the form of an additive or preservative (inorganic phosphorus) is found in foods such as fast foods, ready to eat foods, canned and bottled drinks, enhanced meats, and most processed foods.
