ruddle: A red coloring material on a harness worn by rams so that ewes which have been mated will be marked and identified. Using ruddle helps farmers manage breeding programs and track mated ewes.

root crop: A plant that stores edible material in a root, corm, or tuber and is grown as food. Root crops include carrots, parsnips, swedes, and turnips. Starchy root crops include potatoes, cassavas, and yams. Growing root crops diversifies farm production and provides a stable source of nutrition.

rotational grazing: The movement of livestock around a number of fields or paddocks in an ordered sequence. Also called on-off grazing. Rotational grazing supports pasture health and productivity, improving livestock performance and reducing overgrazing.

residual herbicide: A herbicide applied to the surface of the soil which acts through the roots of existing plants and also new plants as they germinate. Using residual herbicides helps farmers control weeds effectively and protect crop yields.

rounds: Circular walls built to protect sheep from snow drifts. Using rounds helps farmers protect livestock from harsh weather conditions and ensure their safety.

ranching: An agricultural system based on commercial grazing on ranches; the raising of cattle on large grassland farms. Ranching supports sustainable livestock production and helps maintain open grasslands.

rotary sprinkler: A machine used for irrigation purposes. Sprinklers can be fitted with fine spray nozzles for protection of fruit crops and potatoes against frost damage. Using rotary sprinklers supports efficient irrigation and crop protection.

raise: To make plants germinate and nurture them as seedlings; to breed and keep livestock. Effective raising of crops and livestock ensures farm productivity and sustainability.

rotation of crops: Same as crop rotation. Rotating crops supports soil health, reduces pest and disease pressure, and improves overall farm productivity.

rainwater harvesting: The collection and storage of rainwater for agricultural use. Rainwater harvesting helps farmers manage water resources and reduce dependence on external water supplies.
