Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1.Structure and Drafting Rules of Standardization Documents". Drafting. This document replaces GB/T 6274-2016 "Terminology for Fertilizers and Soil Conditioners". Compared with GB/T 6274-2016, except for structural adjustments... Aside from integration and editorial changes, the main technical changes are as follows. ---Fertilizers and soil conditioners (see 2.1.1 in the.2016 version) and inorganic soil conditioners with added fertilizers (see.2016 version) have been removed. 2.1.22), compound fertilizers (see 2.2.7.1 of the.2016 edition), porosity terminology (see 2.3.13 of the.2016 edition); ---Changes have been made to fertilizers (see 3.1.1, 2.1.2 in the.2016 version), organic soil conditioners (see 3.1.23, 2.1.24 in the.2016 version), and ammonia. Water (see 3.2.1.1, 2.2.1.1 in the.2016 edition), compound fertilizers (see 3.2.8.1, 2.2.7.2 in the.2016 edition), water-soluble fertilizers (see...) The definition is found in section 3.2.11.1 (section 2.1.29 of the.2016 version); ---Added biostimulants (see 3.1.4.1), beneficial plant nutrients (see 3.1.4.2), inhibitors (see 3.1.16.1), and fertilizer nutrient release. General terms such as release rate (see 3.1.17), inorganic soil conditioners with added fertilizers and/or beneficial substances (see 3.1.20.2); ---The product terminology categories have been expanded to include other binary/ternary fertilizers (see 3.2.8) and micronutrient fertilizers (see 3.2.10), and polymers have also been added. Coated urea (see 3.2.1.14), potassium thiosulfate (see 3.2.3.4), fertilizer-grade urea phosphate (see 3.2.4.10), and compound fertilizer containing urea sulfate. Materials (see 3.2.8.6), water-soluble fertilizers containing amino acids (see 3.2.11.5), urea containing humic acid (see 3.2.12.11), and compound fertilizers containing seaweed extract (see 3.2.12.11). Product terms such as feedstock (see 3.2.13.8) and biogas slurry (see 3.2.14.12); ---Added the term "particle diffusion index" as a physical property (see 3.3.17); ---Added to the composition water (see 3.4.1.1), neutral ammonium citrate soluble phosphorus (see 3.4.6.1), and EDTA-extracted phosphate (see 3.4). 9) Physicochemical property terms such as the lime effect (see 3.4.18); ---Added the term "self-sustaining disintegration safety" (see 3.5.7). This document is modified to adopt ISO 8157.2022 "Fertilizers, soil conditioners and beneficial substances - terminology".
