This is an important but the most neglected practice in farming. Lime is applied to the soil for the purpose of correcting the soil pH to levels suitable for crop production. Soil is the medium for root growth and development, therefore its pH has to be ideal for increased productivity
Generally, liming is done before the commencement of planting season to enable the lime to have an impact on the soil. The most ideal time to apply lime is three months before planting. The amount and type (Dolomitic or Calcitic lime) of lime to be applied is determined by soil analysis results.
Application of lime to the field depends on the state of the lime whether granulated, powdered or liquid. In all cases, lime should be evenly applied and be able to adjust the pH particularly around the roots zone. Lime should be incorporated throughout the plough zone.
