"Amino Acid-Containing Water-Soluble Fertilizers" (NY 1429-2010) is an agricultural industry standard approved and issued by the Ministry of Agriculture and Rural Affairs of the People's Republic of China on December 23, 2010, and officially implemented on February 1, 2011, replacing the original NY 1429-2007 standard.
This standard specifies the core contents of amino acid-containing water-soluble fertilizers, including product classification, technical requirements, and test methods. It is divided into two categories: micronutrient-based and calcium-based. It requires that the free amino acid content be no less than 10% in solid form and no less than 100 g/L in liquid form, and that the content of micronutrients or calcium components meet the corresponding technical indicators.
As a currently effective fertilizer industry standard, this specification is applied to the quality control of government procurement projects and, together with standards for macronutrient-based water-soluble fertilizers, constitutes the water-soluble fertilizer standard system.
