Concept:Dry farming is a method of crop production in arid or semi-arid regions where crops are grown without irrigation by conserving soil moisture.
Explanation:Farmers store water in the soil during one season and use it for crops in the following season.
This is achieved through practices such as ploughing, mulching, and harrowing.
These practices reduce evaporation, improve water retention, and keep the land productive in dry conditions.
Arable farming simply means growing crops on land.
Intensive cultivation uses large inputs on small land, while extensive cultivation uses large land with fewer inputs.
Neither focuses on year-to-year moisture conservation without irrigation.
Answer:D. dry farming
