How to improve Acid soil


Harm of acid soils

Damage one: an acidic soil will be to make the soil useful microbial reduction, inhibits the growth of beneficial microorganisms and activities, thus, it will affect the decomposition of soil organic matter and the cycle of soil nitrogen, phosphorus, potassium, sulfur and other elements. And it will also cause germs, root diseases increases as soil acidification will increase the breeding and spread of crop root nematode disease.

Damage two: acidic soils of nutrients can cause fixed, such as when the soil pH values below 6 , red soil with decreasing pH and phosphorus fixation rate is soaring, because phosphorus is fixed, greatly reducing the effective utilization of phosphorus, become one of the serious problems in agricultural development.

Damage three: acidic soil will promote some toxic elements (such as aluminium) release, activation, digestion. Such as aluminium ion on the growth of wheat seedlings in soil is toxic; also has a great impact on relative yields of barley, with the exchangeable aluminum content in the soil increased, the relative drop in the yield of barley. And planted crops on acidic soils, not full stand, formation of runt seedling and old seedlings, low production quality.

Method one: Using quicklime and acid, 40-50 kilograms per MU, in full uniform when applying. 1/2 reduction in future application until the modification is neutral or slightly acidic soils.

Method two: plant green manure, increasing organic matter. Application of organic fertilizers, farmyard manure.

Method three: to increase irrigation times (paddy field irrigation can be adopted), caught in the wash light acid damage to the crop.

Method four: acid crops, such as rice, rapeseed, mulberry, tea, sweet potatoes, sugar cane, and other acid-resistant and acid-resistant plants.

Method Five: basic fertilizer. Such as calcium, phosphate rock powder, ash, Ammonium bicarbonate, calcium cyanamide, ammonia, acidic soil and in effect.
