How do the test of an acid done humid season
Answers
Answer:
Explanation:
7 is neutral.
Soil with pH levels above 7 are alkaline; those of less than 7 are acidic.
The lower the pH, the more acidic is the soil.
Soils in humid regions tend to be acidic; those in semiarid and arid regions tend to be around neutral or alkaline.
Acidification is a natural process.
Most commercial nitrogen fertilizers are acid forming, but many manures are not.
Crops have different pH needs—probably related to nutrient availability or susceptibility to aluminum toxicity at low pH.
Organic acids on humus and aluminum on the CEC account for most of the acid in soils.
Management
Use limestone to raise the soil pH (if magnesium is also low, use a high-magnesium—or dolomitic— lime).
Mix lime thoroughly into the plow layer.
Spread lime well in advance of sensitive crops if at all possible.
If the lime requirement is high—some labs say greater than 2 tons; others say greater than 4 tons— consider splitting the application over two years.
•Reducing soil pH (making soil more acid) for acidloving crops is done best with elemental sulfur (S).
