Explanation:
Drip irrigation helps in:
Reduction in weed growth: Drip irrigation delivers water directly to the root zone of plants, which minimizes water exposure to weed seeds. This can help in reducing weed germination and growth.
Reduction in soil erosion: Drip irrigation applies water slowly and evenly, allowing it to be absorbed by the soil at a controlled rate. This helps in preventing runoff and soil erosion, as compared to traditional irrigation methods where water is applied in larger quantities and at a faster rate.
Drip irrigation however, does not reduce soil salinity and might increase in some cases.
