The correct answer is: d) All of the above
Mizoram is a state in northeastern India. It is a mountainous state with a high population density. The state’s economy is based on agriculture, but the limited availability of arable land, soil erosion and landslides, and low levels of soil organic matter are all challenges associated with Mizoram’s soils.
Limited availability of arable land
Mizoram is a mountainous state with a high population density. This means that there is a limited amount of land available for agriculture. The state’s topography also makes it difficult to cultivate land.
Soil erosion and landslides
Mizoram is a state that is prone to soil erosion and landslides. This is due to the state’s mountainous terrain and the heavy rainfall that it receives. Soil erosion and landslides can damage crops and infrastructure, and they can also make it difficult to access agricultural land.
Low levels of soil organic matter
Soil organic matter is important for soil fertility. It helps to improve the soil’s ability to hold water and nutrients. Low levels of soil organic matter can lead to problems such as poor crop yields and soil degradation.
In conclusion, the challenges associated with Mizoram’s soils are limited availability of arable land, soil erosion and landslides, and low levels of soil organic matter. These challenges make it difficult to cultivate land in the state and can lead to problems such as poor crop yields and soil degradation.
