Functionality is in addition to manure fertilizer plant nutrition and soil fertility has the function of special functions other than fertilizer . It should be suitable for the particular soil and crop , and not the primary purpose of a special function . Functional fertilizers do not have a particularly accurate classification . Because it is functional fertilizer , so are classified according to the function . There improving soil type , water -based , growth-promoting type , weed type , insecticide type , sterilization type. In addition to nutritious plant functions, the other functions in addition possess , we should all be called functional fertilizer.

Only meet four requirements , we can put it referred to as functional fertilizer. First, the plant itself is able to directly provide the necessary nutrients nutrition or fertilize the soil ; Second , you must have a particular object ; Third, can not contain laws and regulations do not allow substances added ingredients ; Fourth , you can not to enhance or improve the main function of fertilizer .

Functional fertilizer is not only a new type of fertilizer , and the market potential is great. In the functional positioning of fertilizer to strictly emphasize three demands: First, it must be additional features of fertilizers , can not be the main function ; Second , it is best not to be fertilizer additives ; Third , a major increase fertilizer costs.

Now the development of functional fertilizer in China is still just getting started, though already used in agricultural production , but as a new variety in terms of fertilizer , application and promotion efforts is still relatively small . Current problems mainly in the following aspects: first , the lack of reliable scientific data to support . In this respect , we hope that the relevant functional departments of fertilizer development and production , there must be a complete and scientific data to support . And it is free of such control functions such as nutrient fertilizers job , so, in order to have credible benefits ; Second , the mechanism is not clear . Often deliberately exaggerated effects, which for us is the development of functional fertilizer very unfavorable ; Third , the lack of specification. Functional capabilities vary due fertilizer , how to measure this feature requires the introduction of a specific regulations and standards .

Functional fertilizer will face three trends: First, green or eco- trend ; Second, specific trend ; three are simple trend .

Functional manure fertilizer is the emergence of a new family member , we can explicitly call it a new type of fertilizer , manure is also our functional one important direction for the development of fertilizer , which is indisputable. Although our current laws and regulations in the fertilizer is not allowed inside the added plant growth regulators, or pesticides, but now there are many users , experts have been discussing , is not it conditionally added . So the development of functional fertilizer direction need to be overcome in the development and use of more problems . Functional environment for the development of fertilizer industry, we also need hard work and self-discipline, so as to make functional fertilizer gradually prosper together .
