Unbalanced fertilizer use, as we have been practicing for decades in Ethiopia, results in low fertilizer use efficiency, leading to low economic returns and greater harm to the environment. It is therefore imperative that fertilizers are used in a judicious way based on crop demand and soil nutrient status. In addition, nutrient

even in the absence of air. AN, particularly the fertilizer grade, is difficult to detonate. The sensitivity to detonation depends on a number of factors such as bulk density, porosity and temperature. For fertilizer application, EU regulations require the use of the dense grade, which has low porosity and a high resistance to detonation.

Bacteria break down the dead organisms, a process that requires the use of oxygen. This results in a deficit of oxygen, creating a dead zone where plants and animals cannot exist. Such a dead zone exists in the Gulf of Mexico, and it is at its largest size since measuring began in 1985 — roughly the size of New Jersey.

A weak phosphoric acid (40-55%) is produced from the reaction of PR with sulfuric acid, using a wet- process. The obtained phosphoric acid is then used in the production of a series of liquid or solid fertilizers. The most important ones are single and triple superphosphates (SSP, TSP) and ammonium phosphates (MAP, DAP).
