Can hydrated lime improve acidic soil? What is the principle?

Hydrated lime can improve acidic soil and can be sprinkled in the soil when used. The advantages of improving soil with hydrated lime are: the cost of hydrated lime is low; Hydrated lime will not harm the soil, because it can absorb neutral substances in the air. Other methods to improve acidic soil: applying more green manure; Apply alkaline fertilizers, such as ammonia and plant ash fertilizer.

1. Can hydrated lime improve acidic soil?

Hydrated lime can improve acidic soil (although it looks acidic, it is actually alkaline), and it can be used when scattered in the soil. The advantages of using hydrated lime to improve soil are: the cost of hydrated lime is low; Excessive hydrated lime will not harm the soil because it can automatically absorb neutral substances in the air. Other ways to improve acidic soil: apply more green manure or increase watering times; Apply alkaline fertilizers, such as ammonia, lime nitrogen and plant ash fertilizer.

Second, what is the principle of improving acid soil with hydrated lime?

The main component of hydrated lime is calcium hydroxide, which is an alkaline substance. When dispersed in acid soil, it will react with acid-base neutralization, and the PH value in the soil will change after acid-base neutralization (thus removing acid substances in the soil), so hydrated lime can improve acid soil. The principle of chemical equation for improving acid soil with hydrated lime is: Ca (OH) 2+H2SO4 = CaSO4+2H2O Ca (OH) 2+2HCI = Caci2+2H2O.
