SUITABILITY OF SOIL FOR IRRIGATION
- Particle size, compactness, the position of the water table, depth of soil,
- The presence of organic matter in the soil, are the usual aspects
- that influence the depth of available water in the root zone of the crops.
- Heavy soils like matiar and domat, can retain water for a considerable time.
- As such are considered suitable for growing crops that require a larger amount of irrigation water.
- Sugarcane, rice, wheat, etc. are such crops that can be grown in matiar soils.
- Baluar or sandy soils cannot retain water for a considerable time.
- Such soils are considered suitable for crops that do not require much irrigation water.
- Baluar soils being easily drainable, require frequent watering
- whereas matiar soils require watering at considerable intervals because they can retain water.
- Suitable soil conditions for irrigation may be summarised as follows:
- The soil should be moisture-retentive type so that it may feed the crop for a considerable time.
- The soil should not suffer from erosion, so that fertile soils remain intact in heavy rains and winds.
- The soil should be adequately porous so that proper aeration of the root zone of the crops may take place.
- The soil should possess sufficient nutrients suitable for the proper growth of the crops.
- The soil should not possess an undue concentration of harmful salts.
- The soil should be free from impurities which may favour the development of parasitic organisms for the crops.
- The soil should be easily tillable so that it may be easily prepared for sowing new crops.
