Subsurface tile drainage to remove excess soil moisture
Rainwater harvesting for supplemental crop irrigation
Continuous irrigation without adequate leaching fractions (Correct answer)
Drip irrigation with fresh, low-salinity water sources

Correct answer: Continuous irrigation without adequate leaching fractions

Continuous irrigation without adequate leaching (applying extra water to flush salts below the root zone) causes progressive salt accumulation in soils, reducing crop productivity and soil health.
