sodium: a chemical element which is a constituent of common salt and essential to animal life. Ensuring adequate sodium levels in livestock diets supports overall health and productivity.

specific weight: the bulk density of a grain sample measured in hectolitres or bushels. Monitoring specific weight helps farmers assess grain quality, supporting market value and consumer trust.

stigma: the part of a flower’s female reproductive organ that receives the pollen grains. (NOTE: It is generally located at the tip of the style.) Understanding the structure and function of stigmas helps farmers manage plant reproduction and optimize yields.

spinney: a small wood with undergrowth. Managing spinneys provides farmers with valuable habitats for wildlife and supports biodiversity on farms.

synthetic pyrethroid: a chemical compound used as an insecticide, similar to a pyrethroid but manufactured artificially. Understanding and using synthetic pyrethroids effectively supports pest control and healthy crop growth, enhancing farm productivity.

saturate: To fill something with the maximum amount of a liquid that can be absorbed. Nitrates leached from forest soils, showing that the soils are saturated with nitrogen. Farmers benefit from understanding saturation to manage irrigation and prevent waterlogging or nutrient leaching.

specific: clearly defined and definite. Understanding specific agricultural practices helps farmers achieve targeted outcomes, supporting productivity and sustainability.

set to: An orphan lamb given to a foster mother. Farmers benefit from fostering orphaned animals to ensure their survival and growth.

sweeper bull: a bull used to serve cows that have not been artificially inseminated. Properly managing sweeper bulls ensures efficient breeding programs and livestock productivity, supporting farm profitability.

studded roller feed drill: a type of external force feed seed drill in which fluted rollers are replaced by rolls with studs or pegs. It is suitable for drilling most types of seed. Using studded roller feed drills ensures accurate seed placement and optimal crop establishment, supporting productive agriculture.
