The correct answer is: d) All of the above

Soil acidity is a major concern in Meghalaya because it can limit crop growth, increase plant disease, and reduce nutrient availability.

• Limit crop growth: Acidic soils can limit crop growth by making it difficult for plants to absorb essential nutrients. This can lead to stunted growth, reduced yields, and even crop failure.
• Increase plant disease: Acidic soils can also increase the risk of plant disease. This is because many plant diseases thrive in acidic conditions. When the soil is acidic, it can damage the plant’s cell walls, making them more susceptible to infection.
• Reduce nutrient availability: Acidic soils can also reduce the availability of essential nutrients for plants. This is because many nutrients are bound to soil particles in a way that makes them unavailable to plants. When the soil is acidic, these nutrients are released from the soil particles and can be washed away by rain or irrigation water.

Soil acidity is a serious problem that can have a significant impact on agriculture in Meghalaya. There are a number of things that can be done to address this problem, such as liming the soil, using tolerant crops, and managing irrigation practices.
