Prudhomme said that between 2007 and 2008, the amount of nitrogen fertilizer increased by 4.6%, the amount of phosphate increased by 4.5%, and the amount of potassium increased by 5.9%.
He said that two-thirds of the increase in fertilizer use in the past five years was concentrated in Latin America, especially Brazil, Argentina, and Mexico. In Brazil, only nitrogen supplies are sufficient, and other fertilizers must rely on imports. Other Latin American countries also face such problems.
Thorleif Enger, an IFA official, recently stated that the current status of the fertilizer market is a complete manifestation of the supply and demand situation and the global supply is very tight.
Prudhomme said that by 2010, the fertilizer market will remain tight. He said that at present the capacity utilization rate of the fertilizer industry is 90%.
Brazil is heavily dependent on imports of fertilizers and is therefore seriously affected by the current supply and demand side of fertilizers. In 2007/08, Brazil’s crop production hit a record high, but high production costs have led to a reduction in planting profits.
The increase in food prices has prompted the Central Bank of Brazil to increase its inflation target this year to more than 5%, compared to the target of 4% at the beginning of the year. High fertilizer prices have caused food costs to rise.
Some farmers in Brazil have sued the fertilizer company and claimed that they control the supply so that fertilizer prices are high.
Application Field
Thin film scraper evaporator is widely used in heat interchange project. Particularly in Thermosensitive materials heat interchange, scraper are beneficial in heat interchange process, Through different design of scrapers, the distillation of complex products can be carried out. Quality result have been obtained for dissolution, stripping, reaction, degassing, deodorizing(gas) and so on.

Features
The equipment adopts centrifugal rotor of sliding groove, which is the latest structure evaporator abroad, The film can be formed even at low flow rate, The sediment in treatment solution attached to inner wall can be quickly removed by the movable scraper, evaporation can be increase to 40-69% compare to fixed gap scraper evaporator, listed below are features and functions:
1.High heat transfer coefficient value, high evaporative capacity, Evaporation intensity can reach up to 200kg/㎡high thermal efficiency
2.Short heating time, work under vacuum condition is much more beneficial to thermosensitive materials, keep various components without any decomposition to ensure quality.
3.It can adapt wide range of viscosity changes. High and low viscosity materials can be treated, and viscosity of materials can be as high as 100000 centipoise.
4.rotate the scraper groove can adjust material handling time in evaporator
5.Grinded and polished inner tube can avoid scaling
6.Easy to operate, production runs automatically under sealed condition.
7.Simple structure uses less area occupancy,convenient maintenance
