row crops: Crops planted in rows, such as corn, soybeans, and cotton. Managing row crops effectively includes proper spacing, irrigation, and pest control.

race: A group of individuals within a species that are distinct physiologically or ecologically; also an improvised wooden way along which animals are made to walk. Knowledge of different races assists farmers in selective breeding programs and improves animal handling during transportation.

rural planning: Same as country planning. Effective rural planning supports sustainable agricultural development and land use.

rabbit: A common furry herbivorous rodent (Oryctolagus cuniculus). Raised for meat and fur. Wild rabbits can be pests. Provides farmers with additional income sources from meat and fur production, though they need to manage wild populations to protect crops.

red fescue: A species of grass (Festuca rubra), used on hill and marginal land and in fine-leaved lawns. Red fescue is valuable for pasture management and soil erosion control.

rotating flails: Parts used on manure spreaders to distribute materials and on machines for cutting crops or grass verges. Using rotating flails supports efficient material distribution and vegetation management.

RASE: Abbreviation for Royal Agricultural Society of England. This society promotes agricultural innovation and best practices, benefiting farmers through resources and knowledge sharing.

refrigerated processed foods of extended durability: Prepared and chilled food such as ready meals, which can be kept for longer than fresh food. Abbreviation: REPFEDs. Producing REPFEDs allows farmers to add value to their products and reach broader markets.

roller table: A machine, consisting of a horizontal line of rotating rollers, used for removing stones and clods from a crop such as potatoes. Using roller tables ensures clean and high-quality produce.

runoff: The flow of rainwater or melted snow from the surface of land into streams and rivers; the flow of excess fertilizer or pesticide from farmland into rivers. Nitrate runoff causes pollution of lakes and rivers. Fish are extremely susceptible to runoff of organophosphates; the portion of rainfall which finally reaches a stream. Managing runoff helps farmers protect water quality and ensure sustainable land use.
