Explanation:
The advantages of fertigation in agriculture are include ncreased availability of nutrients to plants is possible and reduction in the leaching of chemical nutrients is possible. Fertigation, which involves the application of fertilizers through irrigation water, allows for better nutrient absorption by plants and reduces the loss of nutrients through leaching. While controlling the alkalinity of irrigation water (option 1) is a possible advantage of fertigation, efficient application of rock phosphate and other phosphatic fertilizers (option 2) is not specific to fertigation.
