In the late 1940s, the researcher discovered that the
condensation product of urea and formaldehyde-Urea Formaldehyde
releases the ammonia obviously lower than Urea, and they have
carried on the experiments in the American pasture, confirmed
that the condensation has good fertilizer effectiveness.
Therefore, many countries began to use it as a slow-release
fertilizer and conduct experiment research. In recent years,
according to eh reports from Japan, Germany and so on, this
condensation also had the functions of promotion soil to form the
granular structure, guaranteeing the soil moisture, preventing
desertification and increasing crops root system penetrating
power. At the same time, it also has the environmental
protection, resource saving, labor saving, etc. Using Urea
Formaldehyde cannot cause crop burn and leaching loss, also it
can gradually release most of the nitrogen throughout the entire
growing season, the rest can be transferred to the next growing
season. In addition, it also has the environmental protection,
resource conservation, the advantages of labor
saving.
Compared with soluble fertilizer, Urea Formaldehyde itself
consists of water soluble parts and water insoluble parts, it
will release nitrogen in soil under moisture, urease,
temperature, etc. Working together. Due to the release speed of
nitrogen depends on water insoluble parts, made it possible to
control the release of fertilizer artificially. But Urea
Formaldehyde release of nitrogen is relatively slow, thus Urea
Formaldehyde is generally not used separately. They always used
in the compound fertilizer containing dissolved nitrogen sources
of rapid release and phosphorus, potassium. The fast release
nitrogen supplies corresponding nutrient in early growing
periods, and Urea Formaldehyde gives and effect to prolong the
efficiency. The result of mixing dissolved nitrogen and Urea
Formaldehyde is to obtain uniform the nitrogenous fertilizer,
which can lengthen the releasing time, and pledge enough nitrogen
for a long period.
Urea Formaldehyde researched & developed by ourselves can
accurately reach the release effect from 30 days to 180 days, and
can be adjusted AI, WIN and HWIN according to the
customers’requirement of the release period, at the same time we
refer to international quality testing standards to ensure that
its quality reaches the international advanced level.
