Embodiment approach

[0011] The organic raw material adopted in the invention is high-quality weathered coal produced in Lingshi area of ​​Shanxi Province, and the content of humic acid in the weathered coal reaches 60-65%.

[0012] 1. The humic acid organic-inorganic compound fertilizer used for flowers, lawns, forest trees, nurseries, and pastures is a fertilizer made of the following components by weight:

[0013] Urea 180kg, superphosphate 330kg, potassium chloride 100kg, humic acid organic fertilizer 390kg

[0014] The above raw materials are produced according to the preparation method provided by the present invention. The produced humic acid organic-inorganic compound fertilizer contains 20% of the nutritional three elements (N 8%, P 6%, K 6%), and the humic acid content HA≥20%.

[0015] 2. The humic acid organic-inorganic compound fertilizer applied to wheat, corn, millet, and sorghum is a fertilizer made of the following components by weight:

[0016] Urea 230kg Ammonium Phosphate 170k...

Abstract

A mixed fertilizer is prepared from urea, P fertilizer, potassium chloride, potassium sulfate and humic acid through proportional mixing, spherizing, low-temp pulverizing, and low-temp baking. Its advantages are high fertility increased by 20%, improving soil, balanced nutrient and high yield of crops.

Description

(1) Technical field [0001] The invention belongs to compound fertilizer, and in particular relates to a humic acid organic-inorganic compound fertilizer and a preparation process thereof. (2) Background technology [0002] Humic acid is an organic fertilizer used as base fertilizer or top dressing of crops. It can promote plant growth, increase crop yield, and play an important role in improving soil structure and physical and chemical properties, and improving soil fertilizer and water retention capacity. Weathered coal humic acid is used as natural bio-organic fertilizer and chemical three-element fertilizer to make organic-inorganic compound fertilizer, which can improve fertilizer efficiency and meet the needs of different crops for nutrients, and at the same time form with radioactive ions, heavy metals, and harmful elements in soil and water. Complexes and chelates protect and purify the environment and fertilize the soil. Farmers welcome granular compound fertilizers...
