Abstract

The present invention is one kind of soil nutrient amendment and its preparation process. The soil nutrient amendment consists of turf, humate, botanical water retainer, trace elements, etc. in the weight proportion properly altered based on the soils and / or crops. It may be prepared into different forms, powder, pellet, etc. It has integrated functions of improving soil structure, nourishing, saving water and reducing pesticide consumption.

Description

technical field [0001] The invention belongs to a soil nutrition conditioning agent and a preparation method thereof, in particular to a soil nutrition conditioning agent composed of peat, sapropel, humic acid, large and medium elements and a biomass water retention agent. Background technique [0002] In order to improve desertification, desertification, degradation and other soil types with low fertility and unreasonable structure, various soil improvers have been developed and developed by countries all over the world. [0003] According to the type of improved soil, soil improvers are divided into common type and special type. The former refers to amendments suitable for various soil types; the latter refers to soils that are specially applicable to a certain type or a certain area, and are highly targeted. [0004] According to the raw materials used to improve soil, soil improvers can also be divided into inorganic type, organic type and organic-inorganic composite ty...
