seed trials: Tests of new seeds to see if they germinate correctly. Farmers benefit from conducting seed trials to evaluate and select the best-performing seed varieties.

strip grazing: a system of grazing which allows animals access to a small part of the field. The rest of the field is protected by a temporary fence, usually electric. Properly managing strip grazing ensures sustainable pasture management and livestock productivity.

subtropical: referring to the subtropics. The islands enjoy a subtropical climate. Subtropical plants grow on the sheltered parts of the coast. Properly managing subtropical crops ensures optimal growth and yields, supporting farm productivity and sustainability.

suckling pig: an unweaned piglet. Properly managing suckling pigs ensures healthy growth and development, supporting livestock productivity and farm profitability.

surface drainage: the removal of surplus water from an area of land by means of ditches and channels. Properly managing surface drainage ensures healthy soil conditions and prevents waterlogging, supporting productive agriculture.

steerage hoe: a hoe mounted behind a tractor and steered by the driver to avoid crop damage. Using steerage hoes ensures precise weed control and healthy crop growth, supporting better yields.

secondary: 1. Less important than something else 2. Coming after something else. Farmers benefit from understanding secondary growth and development stages for better crop and livestock management.

Suckler Cow Premium Scheme: until 2005, a subsidy on female cattle forming part of a suckler breeding herd used for rearing calves for meat production. Now superseded by the Single Payment Scheme. Understanding and accessing support schemes ensures financial support for farmers, promoting sustainable agricultural practices.

sheet erosion: Erosion that takes place evenly over the whole area of a slope, caused by the runoff from saturated soil after heavy rainfall. Farmers benefit from managing sheet erosion to prevent soil degradation and maintain land productivity.

sustainable food chain: a food chain from producer to consumer which is environmentally responsible and sustainable at all stages. Properly managing sustainable food chains ensures responsible resource use and supports farm sustainability.
