China (Mainland) Fertilizer, Urea Formaldehyde

Specifications: Atpresent,our country chemical fertilizer\'\'s annual output had achieved 150 million tons, urea occupies above 1/5.After the urea executes into the soil,can decompose and release out nitrogen under the urine enzyme\'\'s the urea solubility is big,can drain along with the moisture content in soil; In addition, also a part of urea may adhere to the soil pellet surface layer so that difficult to be absorbed by the crops.

Thus, causes the urea\'\'s effective availability generally isonly about30%.Therefore,the various countries was trying to find out the method f how to raise the urea use factor.

At the end of 40\'\'s last century,the researcher discov-ered the urea and the formaldehyde\'\'s condensation product releases the ammonia obviously is lower than the urea, and has carried on the experiment in the American pasture,confirmed this kind of condensation compound has the good fertilizer effectiveness.

Thus, many countries then start to take as the slow-releasing chemical fertilizer to conduct the experimental study.

In recent years according to the reports from Japan, Germany and so on, this kind of condensation compound also had the functions of promo-ting soil to form the granular structure,guaranteeing the soil moisture, preventing desertification and increasing crops root system penetrating the same time also has characteristic, for example, environmental prote-ction, resources economization, and labor force economi-zation.

The composition of formaldehyde urea cannot cause the burn and the leaching loss,can release the majority of nitrogen gradually in the entire growth season, other parts possibly change over to the next growth season.

Compared with solvable fertilizer, urea formaldehyde\'\'s release nitrogen speed is slower,but we have to know that most of the urea formaldehyde do not use always mix with dissolved nitrogen and mixed ferti-lizer for which has phosphorus and kalium components.

The solvable fertilizer provide early period nutrient,me-anwhile,the urea formaldehyde gives and effect to prolong the union of the soluble nitrogenous ferti-lizer and the urea formaldehyde\'\'s only result is to btain the nitrogenous fertilizer of which is evenly and can leng-then the releasing time,Pledge enough nitrogen within a certain long period.
