Dryland farming

Dryland farming (pronunciation: /ˈdraɪˌlænd ˈfɑːrmɪŋ/) is an agricultural technique for non-irrigated cultivation of crops. Dryland farming is associated with dry areas, commonly referred to as arid and semi-arid regions, where rain is the primary source of water for farming.

Etymology

The term "dryland farming" is derived from the English words "dry" and "land", referring to the arid conditions where this type of farming is practiced, and "farming", which refers to the cultivation of crops.

Overview

Dryland farming is practiced in many parts of the world, including the Great Plains of the United States, parts of Australia, Africa, and the Middle East. The technique relies on the science of managing the residual moisture in the soil from the rainy season, and using it to grow crops in the dry season. The crops grown are usually drought-resistant varieties such as sorghum, millet, and certain types of wheat and maize.

Techniques

Key techniques in dryland farming include crop rotation, intercropping, and soil conservation. Crop rotation helps to maintain soil fertility, while intercropping allows for the efficient use of available water. Soil conservation techniques are used to prevent soil erosion and maintain soil health.

Challenges

Dryland farming faces several challenges, including unpredictable rainfall, potential for long periods of drought, and the risk of soil degradation. These challenges require careful management and adaptation strategies to ensure successful crop production.
