straw chopper: a device fitted to the back of a combine which chops straw into short lengths and drops it on the stubble. Chopped straw is easier to plough in. Using straw choppers ensures efficient straw management and soil preparation, supporting productive agriculture.

swede: a vegetable (Brassica rutabaga) with a swollen root. An important forage crop, it is grown for feeding sheep and cattle, either in the field or as winter feed for housed livestock. Swedes have a slightly higher feeding value and keep better than turnips, so they are often lifted and clamped. Properly managing swede crops ensures healthy growth and high yields, supporting farm productivity and profitability.

scab: 1. A disease of which the scab is a symptom. It affects the skin of animals. 2. A fungal disease of fruit and vegetables, including potato scab and apple and pear scab. Farmers benefit from preventing and treating scab to maintain the health of their livestock and crops.

sheep: A ruminant of the genus Ovis, family Bovidae. It is one of many domesticated varieties, farmed for their wool, meat and milk. Most sheep in the UK are kept for meat, and milk production is relatively unimportant. Wool is an important byproduct of sheep farming in the UK, but is the main product of sheep in some other countries, such as Australia. In 2005 the total sheep population of the UK was approximately 40 million, accounting for 30% of all sheep in the EU member states. Sheep are kept under a wide range of environmental and management conditions, from coastal lowland areas such as Romney Marsh to the upland areas of Wales, Scotland and the North of England. Lambs from the upland areas are moved to lowland farms for fattening. In the UK, a great many breeds of sheep have survived and there are some 50 recognised breeds as well as a variety of local types and many crossbreds. More recently, the introduction of continental breeds has increased the variety. A broad classification into three main categories may be made: the long-woolled breeds which include the Romney, Lincoln and Leicester; the short-woolled breeds including the Southdown, Dorset Down and Suffolk, and the mountain, moorland and hill breeds which include the Cheviot, Radnor, Scottish Blackface, Swaledale and Welsh Mountain. Farmers benefit from raising sheep for their versatile products, including meat, wool, and milk, and their adaptability to various environmental conditions.

summer: the season following spring and before autumn, when the weather is warmest, the sun is highest in the sky, and most plants flower and set seed. Properly managing summer crops ensures healthy growth and optimal yields, supporting farm productivity.

short ton: US same as ton. Farmers benefit from understanding and using standardized measurements like short tons for consistent and accurate trade and storage.

S symbol sulphur: Sulphur is an essential element for plant growth, contributing to the formation of proteins and enzymes. Farmers benefit from understanding sulphur’s role in maintaining soil health and enhancing crop yield.

saprophagous: Referring to organisms that feed on decaying organic matter. Farmers benefit from saprophagous organisms by utilizing natural decomposition processes to enrich soil fertility.

soil contamination: the presence of chemical or biological elements which affect the soil’s natural function. Preventing soil contamination ensures healthy crop growth and protects the environment, supporting sustainable farming practices.

scour: To wash wool to remove grease and contaminants. Farmers benefit from scouring wool to produce high-quality fleece for the market.
