Soil Amendment Calcium Hydroxide Granules

Product features:

This product is made into granular calcium hydroxide by granulation process, which has better fluidity than powdered products, and is convenient for mechanical sowing and manual spreading, avoiding the problem of dust pollution during use. Its slow dissolution characteristics can ensure that the soil pH value is increased stably, and will not cause local excessive alkalinity to burn crop roots. It has been treated with heavy metal passivation, ensuring that the content of heavy metals such as lead and arsenic is far lower than the national agricultural environmental protection standards, and will not cause pollution to soil and crops. It can not only adjust the soil pH value, but also provide calcium elements for crops, promote the growth of crop roots and improve the stress resistance of crops. It has a long shelf life and is easy to store and transport.

Product specifications:

The specific technical parameters of this product are as follows: calcium hydroxide purity ≥90.0%, particle size 1-5mm, neutralizing value ≥85% (calculated as CaO), moisture content ≤1.5%, bulk density 0.8-1.0 g/cm³, PH value of 10% aqueous slurry is 12.0-12.5, heavy metal content ≤20mg/kg, 24-hour dissolution rate ≥90%, shelf life is 12 months. It is packaged in 50Kilograms woven polypropylene bags, and needs to be stored in a dry and ventilated place to avoid moisture and water immersion, which will affect the product's dissolution performance.

Product application:

This product is mainly applicable to agricultural planting scenarios such as field crops, vegetable planting, orchards, tea gardens and flower cultivation. It can be used for soil improvement of acidic soil in southern China, adjustment of soil pH in facility agriculture, and supplementation of calcium elements for crops. It can be applied by mechanical spreading or manual spreading, and the application amount can be adjusted according to the original pH value of the soil and the type of crops. It has been widely used in domestic and foreign agricultural planting fields, and has achieved good soil improvement effect, helping farmers increase crop yield and quality.
