From the national chemical fertilizer quality supervision and Inspection Center (Beijing) was informed that, as of 2014 December, the Ministry of agriculture fertilizer registration statistics, a total of 6422 (is handling expired registration certificate 196), in which a large number of elements of water soluble fertilizer 1289, elements in the amount of water-soluble fertilizer 176, water soluble trace element fertilizer 1634, containing amino acid water soluble fertilizer containing humic acid 1575, 1461 water soluble fertilizer, organic water soluble fertilizer with potassium nitrate 88, agriculture 3, agricultural use of modified ammonium nitrate with calcium ammonium nitrate 4, 16 agricultural, agricultural use of potassium and magnesium sulfate 14, agricultural potassium chloride magnesium 1, agricultural use of calcium nitrate 4, with Magnesium sulfate 8 agricultural, elements in the amount of fertilizer 24, trace element fertilizer 24, urea ammonium nitrate solution 4, slow release fertilizer 21, synergistic nitrogen fertilizer synergist for 2, 3, 59 agricultural soil conditioner, water retaining agent 11, potassium dihydrogen phosphate and ammonium 1.

A large number of elements of water soluble fertilizer before 5 kinds of water soluble fertilizer fertilizer registration approval belongs to the product registration inspection, respectively is: a large number of elements of water soluble fertilizer for the 81% pass rate, the unqualified cause of arsenic and trace elements; water soluble trace element fertilizer qualified rate is 89%, the unqualified reason is cadmium and trace elements; content water soluble humic acid fertilizer qualified rate is 89%, the unqualified reason is humic acid; amino acid containing water soluble fertilizer qualified rate is 85%, the unqualified cause of free amino acids in the elements of water soluble fertilizer; qualified rate is 77%, the unqualified reason is medium elements. The other is the fertilizer registration review approval registration inspection qualified products, no worry for 69%, unqualified products are mainly for the slow release fertilizer in agriculture and forestry, water retaining agent, soil conditioner, organic water soluble fertilizer etc..

Analysis indicated that the unqualified raw materials, ammonium phosphate arsenic content exceed the standard, single trace elements in the material cadmium content exceed the standard problem is prominent, the agricultural product safety and environmental risks; and water soluble fertilizer containing humic acid, water-soluble fertilizer containing amino acids, elements in the amount of water soluble fertilizer mainly due to unqualified processing, feed shortage. Slow release fertilizer recent development is swift and violent, but registration inspection the problems reflected worrying, widespread problem of heavy metal materials into, more serious is the production enterprises on the release rate and cycle index in the quality control of the ability to release the existence of high instability, difference technology index and registration of most products inspection obvious again. For soil conditioner, mainly is the degree of controlled production enterprises source of raw materials is low, high and low volatility problems in registration index of calcium oxide, magnesium oxide, silicon oxide content.
