Product Description

UF(Urea Formaldehyde)
MU(Methylene Urea) and UF(Urea Formaldehyde): Composed of a series of carbon-linked polymers, both MU(Methylene Urea) and UF(Urea Formaldehyde) provide usable carbon and nitrogen. Both products are made from reacting urea with formaldehyde under prescribed conditions. Because the formaldehyde is completely reacted in the process, there is no formaldehyde in the finished product. The end result is carbon-linked chains in different molecular lengths, which affect their rate of release. In both Methylene urea and Urea formaldehyde, the carbon-to-nitrogen(C:N) ratio is approximately 1:1, providing an ideal balance of food and energy resources for microbial activity.

Methylene urea consists of a greater proportion of sparingly soluble polymers than urea formaldehyde. The sparingly soluble nitrogen content does not behave like urea. It is "occluded", a protected urea molecule in a methyl molecule, which does not release fast like urea.

Balances the growth of roots and leafy parts.
Increases root mass and elongation.
Helps prevent growth flushes that weaken turf and generate excessive clippings.
Virtues of MU&UF
(1): High content, total Nitrogen is about 38%-40%,
(2):It is neutral, without any poisonous material. It will do no harm to the stem of plant by continuous apply.
(3):It will decompose slowly by the affect of microorganism. The decomposition process is almost similar to fish powder and bean powder does. So it can be the alternative for these high price products.
(4):It will be clinged to the soil strongly and less moved away by water. It can be absorbed by plant easily.
(5): With long-term effectiveness, it also will not produce any organic acid. So it is safe and harmless to the shoot-up and growth of plant. It is suitable for multi-fertilizer cultivation for the reason of low ion concentration.
(6): Can be mixed with all fertilizer. Please avoid using with highly water absorption fertilizer.
(7): What's more, with long-term effectiveness, it is very helpful to some long time growing plant as Turf, fruit trees, flowers. It can reduce the times of applying to save labor and fertilizer.

The decomposition principle of UF&MU: complete biology decomposition
When UF&MU are applied into soil, the microorganisms need to take in the carbon in the METHYLENE and decompose it. The urease will produce ammonium bicar-bonate, and then it would decompose into carbonic acid form and ammonium by adding water. Thus, it is slow release in lower temperature and quicker in higher temperature. Normal Urea could be decomposed to a ammounium form within 4 days under 25 condition, while Ureaform can withstand 2 months with a 50% decomposition rate. Therefore, its result is almost similar to fish powder and bean powder.
