Product Description
Our Agricultural hydrated lime powder is specially built for agricultural production scenarios, produced from high-quality limestone through calcination, hydration digestion and classification grinding. It is a commonly used soil conditioner and plant protection raw material in agriculture. The product can effectively neutralize acidic soil, supplement calcium, improve soil aggregate structure, and can also be used for pesticide preparation, fruit tree whitewashing and soil disinfection, helping crops grow healthily and increase yield.
Different from industrial-grade products, our Agricultural hydrated lime powder optimizes fineness and reaction rate for agricultural application scenarios: with moderate particle size gradation, it releases alkalinity slowly after being spread into soil, continuously regulates soil pH without causing local over-alkalization and root burning; meanwhile, harmful impurities are strictly controlled, which will not damage soil microbial communities or cause phytotoxicity to crops. Our Agricultural hydrated lime powder can not only improve acidic soil and eliminate aluminum toxicity, but also supplement soil calcium nutrition and promote root development. When used with pesticides, it can improve disease prevention effect, making it a cost-effective agricultural material in planting production.

Application Fields
● Acidic soil improvement: Neutralize soil acidity, eliminate active aluminum toxicity, improve soil aggregate structure and aeration, and promote microbial activity.
● Soil heavy metal stabilization: Increase soil pH value, promote heavy metals to form hydroxide precipitation, reduce their bioavailability and decrease crop absorption.
● Pesticide preparation: Mix with copper sulfate to prepare Bordeaux mixture fungicide for disease control of fruit trees and vegetables.
● Fruit tree whitewashing protection: Whitewash trees in winter to prevent frost and sun scald, and kill eggs and bacteria in bark gaps.
● Farmland disinfection and acid adjustment: Used for soil disinfection in facility agriculture to regulate the environment of soil-borne diseases and reduce continuous cropping obstacles.

FAQ
Q1: How much Agricultural hydrated lime powder is needed per mu?
+
-
A1: According to different soil acidification degrees, the conventional dosage is 50-100kg per mu for moderately acidic soil, and can be increased to 100-150kg for severely acidic soil. The specific amount should be determined based on soil pH test results.
Q2: When is the best application effect?
+
-
A2: It is recommended to spread before plowing and incorporate into soil to fully mix the product with soil; fruit tree whitewashing is recommended to be carried out in autumn and winter.
Q3: Can it be used together with acidic pesticides?
+
-
A3: It cannot be directly mixed with acidic pesticides, as neutralization reaction will occur and reduce efficacy; it is recommended to apply separately at an interval of 7-10 days.
Q4: Is there any risk of root burning to crops?
+
-
A4: When applied at the recommended dosage and fully mixed by plowing, root burning will not occur; avoid excessive concentrated application, and it is not recommended for saline-alkali soil.
Customization Capability
We can customize Agricultural hydrated lime powder with different fineness and packaging according to customers' application methods and scenarios. Coarser particle size can be selected for manual spreading and furrow application to reduce dust and achieve sustained release; finer particle size can be selected for mechanical spraying and pesticide preparation for good dispersibility and uniform mixing. Meanwhile, we provide different packaging specifications such as 25kg small bags and 1-ton ton bags, adapting to different needs of agricultural material retail and base bulk procurement.
After-sales Service
We have agronomic technicians to provide full after-sales service for customers. We can provide scientific application schemes of Agricultural hydrated lime powder according to customers' soil types, planted crops and acidification degrees; give targeted dosage and application method suggestions for different planting scenarios such as orchards, farmland and facility agriculture. We can follow up soil conditions during the crop growth cycle and provide adjustment guidance to help customers achieve the optimal effect of soil improvement and crop yield increase.
