prostaglandin: A hormone that is used to make oestrus happen in many animals at the same time and to start the birth process or abortion. Helpful content: Prostaglandins are valuable for synchronizing breeding cycles and managing reproduction in livestock. Proper use can improve herd fertility and streamline breeding programs.

phase separation: The splitting of a mixture into two layers, e.g., in milk, the fat separates from the watery part. Understanding phase separation aids in food processing and ensuring product quality.

pedigree records: Records of pedigree stock kept by the breeder and by breed societies. Pedigree animals are registered at birth and given official numbers. Maintaining pedigree records ensures traceability and the quality of breeding programs.

phosphorite: Any rock that contains phosphorus, used to make fertilizers. Utilizing phosphorite in fertilizer production enhances soil fertility and crop yields.

paratyphoid: A disease of pigs caused by infection with salmonella bacteria. Young pigs run a high fever and may die within 24 hours. Preventing and managing infections like paratyphoid is essential for livestock health and farm profitability.

pulse: Crops harvested for their dry seeds, such as beans, lentils, and peas. Pulses are important for their nutritional value and ability to improve soil fertility through nitrogen fixation.

protectant fungicide: A fungicide applied to the leaves of plants. It can be washed off by rain, so removing the protection. Helpful content: Using protectant fungicides helps prevent fungal infections and protect crop health. Farmers should reapply as needed, especially after rainfall, to maintain effective disease control.

polled stock: 1. Animals that are naturally hornless. 2. Animals that have had their horns removed. Helpful content: Polled stock are easier to handle and pose fewer risks to other animals and handlers. This trait can improve farm safety and reduce management challenges associated with horned livestock.

polder: A piece of low-lying land that has been reclaimed from the sea and is surrounded by earth banks, especially in the Netherlands. Helpful content: Polder farming involves managing water levels and soil salinity. Farmers in these areas can benefit from advanced drainage systems and crop selection suited to reclaimed land conditions.

patch: A small cultivated area with one type of plant growing in it, e.g., a pumpkin patch or onion patch. Managing small patches allows for intensive cultivation and experimentation with different crops.
