scabies: A very irritating infection of the skin caused by a mite which lives under the skin. Farmers benefit from recognizing and treating scabies to ensure livestock welfare and productivity.

strength: the ability of wheat flour to produce a yeasted dough capable of retaining carbon dioxide bubbles until the proteins in the bubble walls become relatively rigid, which happens at about 75°C. The milling quality of wheat is measured by the Hagberg test. Properly managing wheat flour strength ensures high-quality bread production, supporting market value and consumer trust.

salinised: Referring to soil where evaporation leaves salts as a crust on the dry surface. Farmers benefit from addressing salinised soils to prevent reduced agricultural productivity.

sorrel: a plant with a sour juice sometimes eaten as a salad. Varieties include the sheep sorrel and the wood sorrel. Cultivating sorrel provides farmers with a versatile crop for fresh and processed markets, enhancing farm income.

systems approach: a method of farming that uses management techniques and technology to optimise the productivity and sustainability of the entire farm. Adopting a systems approach ensures efficient farm operations and long-term productivity.

saturation: The point at which air contains 100% humidity. The various types of fog are classified by the manner in which saturation is reached. Farmers benefit from monitoring saturation levels for effective irrigation and crop management.

systemic fungicide: a fungicide that is absorbed into the plant through the root or leaf and moves around within the plant, killing fungi. Properly managing systemic fungicides ensures effective disease control and healthy crop growth, enhancing farm productivity.

stem: the main stalk of a plant that holds it upright; a subsidiary plant stalk, branching out from the main stalk or attaching a leaf, flower, or fruit. Proper management of plant stems ensures healthy growth and optimal yields.

strip cup: a container into which the first drops of milk are drawn by hand from the teats of the cow before the milking machine is attached to the udder. Properly managing strip cups ensures milk hygiene and quality, supporting dairy productivity and consumer health.

synthetic organic compound: a compound containing carbon and hydrogen manufactured from synthetic materials. Understanding and using synthetic organic compounds effectively supports efficient farm operations and productivity.
