Response Curve

response curve: A graph showing the yield (or some associated factor) against fertilizer input, level of feed, antibiotics, etc. Using response curves helps farmers make data-driven decisions to optimize inputs and maximize productivity.

R

Resist

resist: To fight off or not be subject to the effects of something. Developing resistant crop varieties helps farmers manage pests and diseases, ensuring stable yields and reduced losses.

R

Rainfall

rainfall: The amount of water that falls as rain on an area over a period of time. Understanding rainfall patterns helps farmers plan irrigation and manage water resources effectively.

R

Ripper

ripper: A heavy cultivator consisting of a strong frame with long tines attached to it. It is used to break up compacted soil to allow free passage of air and water. Also called subsoiler. Using rippers helps farmers improve soil structure and enhance crop growth.

R

Replacement Rate

replacement rate: The rate of introduction of heifers into a dairy herd to replace aging cows or cows with low milk yields. Managing replacement rates helps farmers maintain productive dairy herds and optimize milk production.

R

Runt

runt: A small individual animal, one that is smaller than average for its kind; the smallest animal in a litter. Managing runts ensures they receive adequate nutrition and care, promoting healthy growth and development.

R

Regulator

regulator: Something or someone controlling a process or activity. Using regulators helps farmers manage farm operations efficiently and ensure compliance with industry standards.

R

Recommended Daily Amount

Recommended Daily Amount: The amount of a substance, e.g. a vitamin or mineral, that should be consumed each day for a person or animal to be healthy. Abbreviation: RDA. Understanding RDAs helps farmers ensure their livestock receive proper nutrition, enhancing growth and productivity.

R

Rut

rut: A period of intense sexual activity that occurs in males of various mammals such as cattle, sheep, and particularly deer. Understanding rutting behavior helps farmers manage breeding programs and livestock health.

R

Rooting Depth

rooting depth: The depth of soil from which plant roots take up water, or the depth of soil to which roots reach. Understanding rooting depth helps farmers manage irrigation and optimize crop growth.

R

Replant

replant: To grow plants in an area again; to put a plant in the ground again. Replanting helps farmers maintain continuous crop production and manage soil health.

R

Red Data Book

Red Data Book: A catalogue formerly published by the IUCN, listing species which are rare or in danger of becoming extinct. The information is now available in a searchable database. The Red Data Book helps farmers and conservationists identify and protect endangered species, promoting biodiversity.

R

Resistant

resistant: Referring to something which is unaffected by a disease, stress factor, process, or treatment. Developing resistant crop and livestock varieties enhances farm resilience and productivity.

R

Regeneration

regeneration: The process of vegetation growing back on land which has been cleared or burnt. Supporting regeneration helps farmers restore soil fertility and biodiversity, improving long-term farm productivity.

R

RSPB

RSPB: Abbreviation for Royal Society for the Protection of Birds. The RSPB supports farmers by promoting sustainable land management practices that protect bird habitats.

R

Rouen

Rouen: A breed of table duck. The drake has a green head and neck, rich claret-colored breast, and grey-black body. The female is mostly brown. Raising Rouen ducks provides farmers with a reliable source of high-quality meat and eggs.

R

Rothamsted

Rothamsted: The site of the Agricultural Experimental station, established in 1843 by John Bennett Lawes. The station specialized in research into plant nutrition and demonstrated the importance of nitrogen, phosphorus, and potassium to plants. Today it is important for its research into biotechnology and is to a large extent sponsored by the BBRSC. Rothamsted research supports agricultural innovation and best practices, benefiting farmers through improved crop and soil management techniques.

R

Royal Agricultural Society Of England

Royal Agricultural Society of England: An organization whose main task is running the annual Royal Show held at The National Agricultural Centre, Stoneleigh, Kenilworth, Warwickshire. Abbreviation: RASE. The RASE promotes agricultural innovation and best practices, benefiting farmers through resources and knowledge sharing.

R

Right Of Access

right of access: The right of someone to be able to get to land by passing over someone else’s property; the right of the public to walk in areas of the countryside, providing they do not harm crops or farm animals. Understanding right of access helps farmers manage land use and protect crops and livestock.

R

Rack

rack: A frame of wooden or metal bars which holds fodder, and from which animals can eat. Helps farmers efficiently feed livestock, reducing waste and ensuring animals have constant access to food.
