Foreword

GB/T 17767 "Organic - inorganic compound fertilizer and method" is divided into three parts. --- Part 1. total nitrogen content; --- Part 2. phosphorus content; --- Part 3. The total potassium content. This section is GB/T Part of 117,767. This section of the American Association of Public Analysts Manual of Analytical Methods (AOAC) (1984) in 2.061, "Determination of the total nitrogen content of fertilizers party Law --- Improved Synthetic nitrogen Law ", the former Soviet Union national standards ГOCT26715. 1985" Determination of the total nitrogen content of organic fertilizer, "a Consistency not equivalent. This Part replaces GB/T 17767.1-1999 "Organic - inorganic Compound Fertilizers - Determination of total nitrogen content." The main difference between this version and the GB/T 17767.1-1999 are. --- Sodium hydroxide standard titration solution from 0.1mol/L to 0.5mol/L; --- The calculation formula of total nitrogen content was rewritten. This part is proposed by the China Petroleum and Chemical Industry Association. This part of the National Standardization Technical Committee and soil conditioners Fertilizers (SAC/TC105) and focal point responsible for the interpretation. This section drafted by.
