S

sulphur deficiency: a lack of sulphur in the soil, leading to deficiency in plants. Properly managing sulphur deficiency ensures healthy crop growth and prevents yield losses, supporting farm productivity.

stakeholder: a person who has an interest in something such as a new environmental policy and is personally affected by how successful it is and how difficult it is to put in place. Engaging with stakeholders ensures collaborative decision-making and support for sustainable agricultural practices.

sheen: The bright shiny appearance of a surface, used of fruit, animals’ coats, meat, etc. Farmers benefit from understanding sheen as an indicator of quality and health in produce and livestock.

sulphate of ammonia: same as ammonium sulphate. Understanding and using ammonium sulphate effectively supports soil fertility and healthy crop growth, enhancing farm productivity.

sow: to put seeds into soil so that they will germinate and grow; a female pig. Proper sowing techniques ensure healthy crop establishment and growth, leading to better yields.

silver-laced Wyandotte: A dual-purpose breed of poultry. The feathers are silvery, with black edges, especially on the tail. Farmers benefit from raising silver-laced Wyandotte poultry for their efficient meat and egg production.

sentient: Capable of feeling and perception. Since 1997 EU law has recognised that animals are sentient, and this concept lies behind the animal welfare codes that set out guidelines for the treatment of farm animals in the United Kingdom. Farmers benefit from understanding sentience for ensuring animal welfare and compliance with regulations.

sciarid fly: A pest (Bradysia) affecting greenhouse pot plants. The larvae feed on fine roots causing plants to wilt. Farmers benefit from controlling sciarid fly to protect greenhouse crops and ensure healthy plant growth.

subculture: a culture of microorganisms or cells that is grown from another culture. Properly managing subcultures ensures effective laboratory practices and supports agricultural research.

soil conservation: the use of a range of methods to prevent soil from being eroded or overcultivated, by irrigation, mulching, etc. Also called conservation of soil. Implementing soil conservation practices ensures long-term soil health and fertility, promoting sustainable agricultural productivity.
