Explanation

Statement 1 (Correct) Micro-irrigation delivers water directly to the plant's root zone, minimizing evaporation and water wastage. This allows for a more targeted application of fertilizers and nutrients, reducing their loss in the soil.

Statement 2 (Incorrect) While micro-irrigation is very efficient in water usage, it's not the only option for dryland farming. Other methods like drip irrigation or rainwater harvesting can also be used.

Statement 3 (Correct) Micro-irrigation uses less water compared to traditional methods like flood irrigation. This can help conserve groundwater resources and potentially slow down the receding water table in some areas, depending on the specific water management practices employed.
