Food production fertilizers

The additional and steadily increasing demand for biofuels could lead to a situation where production of biomass derived fuels finally compete with food production. People who can afford cars can pay more for biomass for fuels than people in non-industrialised countries can pay for food production. Fertile soil in non-industrial countries might then be used for energy crops instead of food. This may eventually lead to a situation where only bad soil is left for food crops and the poor, which in addition would eventually also lead to further deforestation of the World s rainforests.

Fertilizer Use. The worldwide use of fertilizers has an important, positive effect on the environment. Conservative estimates (112) iadicate that about 30% of world food production is direcdy attributable to fertilizer use. Without fertilizer, therefore, at least 30% mote virgin land would have to be devoted to agriculture, and 30% more labor and other resources would have to be expended. Even more serious would be the effects of land tillage and cropping without nutrient replenishment. Past experience has shown that, under such a condition, crop yields progressively decrease, the land eventually becomes barren, and forces of wiad and water erosion prevail. 

Capacity, Production, and Consumption. Ammonia production has worldwide significance about 85% of the ammonia produced is used for nitrogen fertilizers. As the primary source of fertilizer nitrogen, it is key to solving world food production requkements. The remaining 15% goes into various industrial products such as fibers, animal feeds, explosives, etc. 

Plant nutrient sulfur has been growing in importance worldwide as food production trends increase while overall incidental sulfur inputs diminish. Increasing crop production, reduced sulfur dioxide emissions, and shifts in fertilizer sources have led to a global increase of crop nutritional sulfur deficiencies. Despite the vital role of sulfur in crop nutrition, most of the growth in world fertilizer consumption has been in sulfiir-free nitrogen and phosphoms fertilizers (see Fertilizers). 

According to [18], 29% of emissions produced within the EU is related to the food production. However, these emissions arising within food production are related not only to the field cycle but also to the production of fertilizers and agrochemicals, processing or all process transport. 

Feeding a world population of over 6 billion requires the use of tools of all types. Not only is the machinery of agriculture important, but so are the chemicals of agriculture. The use of effective fertilizers is essential to increase food production from a tillable land mass that (at least in the United States) is shrinking. Phosphates are an important constituent in many types of fertilizers, and their production involves primarily inorganic chemistry. 

At present most of the pesticide and fertilizer storehouses are in a very bad condition. None of them answer to environmental and sanitary demands. Transportation, usage, distribution and storage of chemicals are not regulated. Hazardous chemicals are in sale everywhere - in the market, on the roads, in the boxes with food products, often without labeling. It is impossible to control chemicals. There is not a special waste disposal.

A large increase in biomass energy production has the potential to cause serious environmental problems. Land use issues and concerns about pollution are major concerns. Areas with fragile ecosystems and rare species would need to be preserved. Agricultural lands would also compete with food production. The loss of soil fertility from overuse is a concern. Biomass production would need to be varied and sustainable while preserving local ecosystems. 

A titrimetric method that has been used for many years for the determination of nitrogen or protein in a sample is the Kjeldahl method. Examples of samples include grain, protein supplements for animal feed, fertilizers, and food products. It is a method that often makes use of the back titration concept mentioned above. We will now describe this technique in detail. 

Contrary to popular belief, application of chemical substances, such as pesticides or fertilizers, in food production is not as harmful as rumors and urban myths would seem to indicate. Pesticides eliminate pests that would otherwise be a frequent cause of poisoning of grains, vegetables, and fruit due to the toxic products of their metabolisms. Chemically synthesized fertilizers are more easily detectable in food than their natural substitutes, which facilitates their adoption for use on food products (Moghissi 1998). 

The manufacture of phosphorus-derived chemicals is almost entirely based on the production of elemental phosphorus from mined phosphate rock. Ferrophosphorus, widely used in the metallurgical industries, is a direct byproduct of the phosphorus production process. In the United States, over 85% of elemental phosphorus production is used to manufacture high-grade phosphoric acid by the furnace or dry process as opposed to the wet process that converts phosphate rock directly into low-grade phosphoric acid. The remainder of the elemental phosphorus is either marketed directly or converted into phosphoms chemicals. The furnace-grade phosphoric acid is marketed directly, mostly to the food and fertilizer industries. Finally, phosphoric acid is employed to manufacture sodium tripolyphosphate, which is used in detergents and for water treatment, and calcium phosphate, which is used in foods and animal feeds. 

Some of these government agencies and private companies, because of the nature of their business, will utilize the services of an analytical chemistry laboratory as part of their overall need to assure the required quality operation. For example, municipal governments will employ the use of an analytical chemistry laboratory to test their water supply on a regular basis to make sure it is free of toxic chemicals. The pharmaceutical company will house an analytical chemistry laboratory within its facility to routinely test the products it produces and the raw materials that go into these products to make certain that they meet the required specifications. A fertilizer plant will utilize an analytical chemistry laboratory to confirm that the composition of its product meets the specifications indicated on the individual bags of fertilizer. Companies that produce a food product, such as snack chips, cheese, cereal, or meat products, will have an analytical chemistry laboratory as part of their operation because they want to have the assurance that the... 

The single largest use of ammonia is its direct apphcation as fertdizer, and in the manufacture of ammonium fertilizers that have increased world food production dramatically. Such ammonia-based fertilizers are now the primary source of nitrogen in farm soils. Ammonia also is used in the manufacture of nitric acid, synthetic fibers, plastics, explosives and miscellaneous ammonium salts. Liquid ammonia is used as a solvent for many inorganic reactions in non-aqueous phase. Other apphcations include synthesis of amines and imines as a fluid for supercritical fluid extraction and chromatography and as a reference standard in i N-NMR. 

This work will greatly enhance the reliability and effectiveness of sulphur fertilization and greatly improve the efficiency of agricultural food production. In light of present and forecasted world food needs, this will be a significant accomplishment. ...
