Humic acid in peat particle and preparation method thereof

Abstract

The present invention belongs to the field of soil and fertilizer, and is especially one kind of organic material comprising turf and humate and its preparation process. The organic material is granular organic fertilizer prepared through spraying humate to turf and granulating, the turf is grass peat with medium decomposition degree and ash content below 50 %, and the humate is potassium humate, sodium humate or ammonium humate from turf, lignite or weathered coal. The organic material of the present invention can increase organic matter content in soil, improve soil aggregate structure of and proportion among solid phase, liquid phase and gas phase in soil, promote plant growth, raise potash fertilizer and phosphate fertilizer utilizing rate and raise agricultural product quality, has other advantages, and is suitable for various types of soil.

Description

technical field

[0001] The invention belongs to soil fertilizer, in particular to an organic material composed of peat and humate and a preparation method thereof. Background technique

[0002] Preventing land degradation and improving soil organic matter is a long-term basic measure. Organic matter is an important indicator of soil fertility. It can affect the physical, chemical and biological properties of soil, maintain and improve soil structure, supply soil microorganisms with carbon sources, and promote their reproductive activities. Therefore, organic matter is an important indicator in organic fertilizers, organic-inorganic compound fertilizers, compound fertilizers and BB fertilizers. At present, the method of increasing soil organic matter is often to add organic materials to the soil or add various granular fertilizers made from these organic materials.

[0003] The main materials for making organic fertilizers in my country come from the following aspects: 1. T...
