What are the disadvantages of liming?
Disadvantages include the potential need for annual application, potential for higher cost than conventional liming and difficulty in getting large pH changes with relatively light applications of lime.
Why is liming done?
The primary reason to apply agricultural lime is to correct the high levels of acidity in the soil. Acid soils reduces plant growth by inhibiting the intake of major plant nutrients -nitrogen, phosphorus and potassium.
How do you determine the lime requirement of soil?
An LR is calculated based on three factors: 1) the soil's initial pH, 2) the desired or target pH and 3) the soil's LBC (in the current method, it is LBCEq). The LR is typically presented as the pounds of lime per acre needed to raise soil pH to the target value and can be calculated as shown below.
How long does lime need to be in the soil?
In the past, surface-applied lime was not recommended because earlier research indicated that 18 to 24 months might be required before a rise in soil pH was measured. This period of time was often needed to allow movement of the lime into the soil (0.5 to 1 cm each year) and to allow for the chemical reactions to occur.
