The correct answer is (c) 1, 3 and 4 only.

Fertigation is the process of applying fertilizers and other water-soluble products through an irrigation system. Some of the advantages of fertigation in agriculture are:

Controlling the alkalinity of irrigation water is possible: Fertigation can help to control the alkalinity of irrigation water by injecting acid-based fertilizers into the irrigation system. This can help to prevent the build-up of alkaline salts in the soil.

Efficient application of Rock Phosphate and all other phosphatic fertilizers is possible: Fertigation can help to ensure that phosphorus fertilizers are applied efficiently and uniformly to the root zone of the crops.

Increased availability of nutrients to plants is possible: Fertigation can help to increase the availability of nutrients to plants by applying them directly to the root zone in a soluble form. This can lead to better plant growth and higher yields.

Reduction in the leaching of chemical nutrients is possible: Fertigation can help to reduce the leaching of chemical nutrients into the soil and groundwater by applying them in a controlled and targeted manner. This can help to minimize environmental pollution and reduce fertilizer costs.
