Does corn need lime?
The need for lime
A pH of 6.0 is adequate for growing corn, soybean, sugar beets and most small grains. Alfalfa prefers a pH of 6.5. Most soil testing labs will test the buffer pH of soil when the water pH is less than optimum levels for crop growth.
Does lime help corn grow?
Managing pH levels becomes even more important if you’re growing continuous corn. … High-yielding growers hold soil pH constant, and don’t let it swing up and down. Yield losses because of acid soil occur gradually. But, when you add lime, it takes two to three years to bring yields back up.”
Is acidic soil good for corn?
The soil pH level for corn should be close to neutral or slightly acidic. This is the same pH level recommended for most vegetables. … In general, corn is highly adaptable, so it can tolerate a fairly wide pH range. Soil that is slightly acidic though, between 6 and 6.5, will provide the best conditions for growth.

Why is corn soaked in lime?
Lime and ash are highly alkaline: the alkalinity helps the dissolution of hemicellulose, the major glue-like component of the maize cell walls, and loosens the hulls from the kernels and softens the maize.
Can you add too much lime to soil?
Addition of excess lime can make soil so alkaline that plants cannot take up nutrients even when these nutrients are present in the soil. The soil may also accumulate excess salts. These conditions stunt plants and cause yellowing of leaves.
Can I add lime to soil after planting?
You can wait and add lime to your garden soil in the spring. However, this should be done several weeks before you plan to sow your garden. The more lead time you have, the better the lime nutrients will be worked into the soil.
