How is over-irrigation damaging to soil health and crop yield?

Over-irrigation poses significant threats to soil health and crop yield. By continuously saturating soil, over-irrigation leads to various issues that affect both the environment and agricultural productivity.

  • Soil Erosion: Excessive water can wash away vital topsoil, reducing its fertility and structure needed for healthy crops.
  • Nutrient Leaching: Over-watering causes essential nutrients such as nitrogen and phosphorus to leach deeper into the soil, making them inaccessible to plant roots.
  • Root Suffocation: Saturated soils restrict air flow, leading to oxygen-deprived roots and stunted plant growth.
  • Salt Build-Up: Irrigated water often contains salts, which accumulate in the soil over time, disrupting nutrient uptake by plants.
  • Disease Promotion: Wet conditions create ideal environments for fungal diseases, further diminishing crop yield.

Therefore, proper irrigation management is crucial for maintaining soil health and maximizing crop production.
