Detailed Solution

Because laterite soil is acidic and poor in nutrients, a balanced fertilizer strategy is key. Simple, effective mixes can be created using both chemical and organic sources. Always conduct a soil test to get a precise recommendation.

Here are some simple fertilizer mixes suitable for lateritic fields:

General Purpose Chemical Mix (Basal Dose): This mix provides a balanced NPK (Nitrogen, Phosphorus, Potassium) supply.
- Nitrogen (N): Urea or Ammonium Sulphate.
- Phosphorus (P):Rock Phosphate is an excellent choice for acidic soils as it is a slow-release source and less prone to fixation than DAP or SSP.
- Potassium (K): Muriate of Potash (MOP).
- A typical NPK ratio to start with might be 1:2:1, reflecting the soil's high phosphorus requirement.
Effective Organic Mix: This mix improves soil health while providing nutrients.
- Base: Well-decomposed farmyard manure or compost (10-15 tonnes per hectare).
- For Phosphorus (P):Bone Meal is a superb organic source of phosphorus and calcium that works very well in acidic soils.
- For Potassium (K):Wood Ash can be used in moderation. It provides potassium and has a liming effect, helping to reduce acidity.
