what is the best methodology for Management of Calcareous soils?
i want the simple method to manage calcareous soils to farming community
Calcareous soils are soils in which a high amount of calcium carbonate
dominates the problems related to agricultural land use. They are characterized by the presence of calcium carbonate in the parent material and by a calcic horizon, a layer of secondary accumulation of carbonates (usually Ca or Mg) in excess of 15% calcium carbonate equivalent and at least 5% more carbonate than an underlying layer.
SIMPLE MANAGEMENT OPTIONS
Addition of copious amounts of organic matter which release organic acids during decomposition for solubilising CaCO3 and to release the fixed P. Regular application of ZnSO4 @ 25 – 50 kg ha-1. Application of phosphatic fertilisers by placement method to overcome the
problem of P fixation. Foliar application of micronutrients in their respective sulphate form.
