What is Water Management?

Water Management is the systematic use, conservation, distribution, and monitoring of water for agricultural production. Its primary objective is to provide crops with sufficient water while reducing unnecessary losses.

Irrigation scheduling, drainage management, rainwater harvesting, soil-moisture monitoring, mulching, and efficient irrigation systems are important components of agricultural water management.

Over-Irrigation & Under-Irrigation

Both over-irrigation and under-irrigation can damage crops. Excessive irrigation may cause waterlogging, nutrient leaching, root problems, and salinity in some soils.

Insufficient irrigation can result in wilting, poor growth, flower or fruit drop, and reduced yield. Water stress can be identified by observing soil moisture, plant condition, crop growth, and weather conditions.

However, irrigation decisions should not be based only on surface soil dryness.

Efficient Irrigation Practices

Practical water management involves scheduling irrigation according to the crop, soil type, weather, and growth stage. Drip and sprinkler irrigation systems can improve water-use efficiency for suitable crops and farming conditions.

Mulching can reduce evaporation from the soil surface, while proper field leveling can improve the uniform distribution of irrigation water.

Water Conservation & Monitoring

Farmers should also consider rainwater harvesting, farm ponds, groundwater conservation, and appropriate drainage systems where suitable.

Regularly monitoring irrigation quantity and frequency can help identify water wastage. The goal should be to provide adequate water to the crop without creating unnecessary losses or unfavorable soil conditions.
