International Wool Secretariat: A group which represents countries which export wool. Abbr IWS. Helps wool farmers with market support and research.

intensive agriculture: A method of farming in which as much use is made of the land as possible by growing crops close together, growing several crops in a year or using large amounts of fertilizer. Opposite extensive agriculture. Also called productive agriculture. Helps farmers maximize land use efficiency.

in-field: Formerly, the field nearest the farmstead, regularly manured and cultivated. In-fields are still preserved on some hill farms. Helps farmers manage land use and cultivation practices.

in-lay: A period when a hen is laying eggs. Helps farmers manage poultry production cycles.

indigo: A tropical plant of the pea family which is a source of blue dye. Genus: Indigofera. Helps farmers grow crops for natural dyes.

immunity: 1. The natural or acquired ability of a person or other animal to resist a microorganism and the disease it causes. The vaccine gives immunity to tuberculosis. 2. The ability of a plant to resist disease through a protective covering on leaves, through the formation of protoplasts or through the development of inactive forms of viruses. Knowledge of immunity helps farmers protect crops and livestock from diseases.

International Rice Research Institute: An organization established at Los Banos, Philippines in 1959. Abbr IRRI. Supports farmers with research on rice production.

intercrop: A crop which is grown between the rows of other crops. Helps farmers diversify crop production.

Indian game: A breed of table poultry, often black with yellow legs. Helps farmers choose suitable poultry breeds for meat production.

ICCO: International Cocoa Organization – an international organization set up to stabilize the international market in cocoa by holding buffer stocks to offset seasonal differences in production quantities. Supports cocoa farmers’ livelihoods.

IPM: Integrated pest management. Helps farmers effectively manage pests with minimal environmental impact.

incubator: A special unit providing artificial heat used to hatch eggs. Incubators are available as small trays, or as large rooms for large-scale producers. Helps farmers increase hatching success rates.

inorganic acid: An acid which comes from a mineral. Helps farmers understand chemical properties and applications.

immunization: The process of making an animal or person immune to a disease, typically through vaccination. Immunization is vital for preventing disease outbreaks and maintaining herd health.

infertility: The inability to reproduce or have offspring. Helps farmers understand and address reproductive issues in livestock and crops.

incorporate: 1. To apply chemicals such as slug pellets by spreading them in rows at the same time as the seed is sown, as opposed to broadcasting. 2. To plough back straw or green manure into the soil. Helps farmers integrate organic matter into the soil for improved fertility.

inoculation: 1. The act of inoculating. 2. An injection against a particular disease. A diphtheria inoculation. Helps farmers implement vaccination programs.

inherit: To receive a genetically controlled characteristic from a parent. Flower color is inherited. Helps farmers understand genetic traits and breeding outcomes.

infective: Referring to a disease caused by a microorganism, which can be caught from another person but which cannot always be directly transmitted. Helps farmers understand the nature and transmission of diseases.
