Recently, the Ministry of Agriculture released the people's Republic of China Ministry of agriculture Bulletin No. 235, the "notice", approved the release of the latest batch of agricultural industry standards, shall be formulated by the national fertilizer quality supervision and Inspection Center (Beijing) the fertilizer and soil conditioner and organic matter classification determination "NY/T2876-2015," of fertilizer synergistic agent dicyandiamide content determination of "NY/T2877-2015," the water soluble fertilizer poly aspartic acid content determination "(NY/T2878-2015) and the water soluble fertilizer Co, Ti content determination" (NY/T2879-2015) of four fertilizer standard name on the list. The four standard issued is to do a good job of the key link of product quality supervision, to further improve the China's fertilizer technology standard system and its implementation will effectively enhance the service level of fertilizer management and scientific guidance of fertilizer production and use, a strong impetus to the healthy and orderly development of the fertilizer industry. Standards will be implemented in April 1, 2016.
According to the existing research results, the same amount of organic materials because of the degree of maturity is different, in which different composition and structure of organic matter, effects on Soil and plants. The fertilizer and soil conditioner and organic matter classification determination of "standard method is proposed in order to solve the technical target of the product on setting unscientific. The standard provides related terminology, classification of organic matter and readily oxidizable organic matter content, organic matter content, total organic matter content and ash content test method, applicable to organic materials as the main raw material through fermentation degradation process of solid fertilizers and soil conditioners, also applies to non compost, agricultural waste and fermentation intermediates products solid organic materials. Standard innovation point is: is proposed to describe the degradation degree of organic materials readily oxidizable organic matter index, second is will with organic phase correlation of total organic matter content, ash content of grading system, to clarify the relation of inclusion, three is the moisture content determination of precision, the scientific evaluation to agricultural organic waste as the main raw material for fertilizer, soil conditioner, composting and fermentation process intermediates provide technical means.
The fertilizer synergistic agent dicyandiamide content determination ", the water soluble fertilizer poly aspartic acid content determination, and the water soluble fertilizer cobalt, titanium content determination," the promulgation and implementation of the standards, to fill the gaps in the fertilizer industry in China, changed quantitative test fertilizer synergistic agent dicyandiamide, water soluble fertilizer in poly aspartic acid, cobalt, titanium content no unified standard situation.
