deintensified farming: Farming which was formerly intensive, using chemical fertilizers to increase production, but has now become extensive. Extensification. Deintensified farming focuses on sustainable practices and reduced chemical inputs. Farmers should adopt practices like crop rotation, organic amendments, and integrated pest management to enhance soil health and productivity. Understanding the principles of deintensified farming can help farmers transition to more sustainable and resilient agricultural systems.

dipterous: Referring to an insect such as a fly with two wings. Managing dipterous insects involves implementing proper pest control measures and monitoring techniques. Farmers should use integrated pest management practices to reduce the impact of dipterous insects on crops and livestock. Understanding the characteristics and behavior of dipterous insects will aid in developing effective pest management strategies.

dag: A tuft of dirty wool round the tail of a sheep. Regularly removing dags (a process called dagging) is essential for maintaining sheep hygiene and preventing flystrike, a condition where flies lay eggs in the dirty wool, leading to maggot infestations. Keeping sheep clean reduces the risk of disease and improves wool quality.

Dartmoor: A breed of large moorland sheep, white-faced with black spots, and a long curly fleece. Dartmoor sheep are known for their resilience and quality fleece. Farmers raising Dartmoor sheep should focus on proper grazing management, regular shearing, and health monitoring to maintain flock productivity. Marketing the unique characteristics of Dartmoor wool can attract premium buyers.

dietary: Referring to diet. Dietary practices are crucial for maintaining the health and productivity of livestock. Farmers should ensure that animals receive a balanced and nutritious diet, tailored to their specific needs. Working with veterinarians and nutritionists to develop proper dietary plans will help optimize animal health and farm productivity.

dehorning: The process of removing or preventing the growth of horns on livestock. Dehorning can reduce injuries and improve safety in animal handling.

dichlorodiphenyltrichloroethane: Full form of DDT, an insecticide that was formerly used especially against malaria-carrying mosquitoes. It is now banned in many countries because of its toxicity and ability to accumulate in the environment. Formula: C14H9Cl5. Farmers should be aware of the historical use and current ban on DDT to avoid environmental contamination and legal issues. Understanding alternative pest control methods will help manage pests effectively while complying with regulations and protecting the environment.

deflector plate: An attachment in a slurry spreader which spreads the slurry over a wide area. Using a deflector plate in slurry spreading can improve the distribution of nutrients and reduce environmental impact. Farmers should ensure proper calibration and maintenance of slurry spreaders to achieve uniform application. Understanding the nutrient content of slurry and matching it to crop needs can enhance soil fertility and crop growth.

domestic: Referring to the home or kept as a farm animal or pet. Domestic animals like dogs, cats, pigs, and goats are integral to farm life, providing companionship, labor, and food. Proper care and management are essential for their well-being.

disintegrate: To break up into small parts. Proper management of disintegration processes is important for maintaining soil health and preventing pollution. Farmers should implement practices like crop rotation, organic amendments, and proper waste management to enhance disintegration and nutrient cycling. Understanding the factors contributing to disintegration will aid in developing effective management strategies.

diploid: Referring to an organism that has two matched sets of chromosomes in a cell nucleus, one set from each parent. NOTE: Each species has a characteristic diploid number of chromosomes. Understanding diploid organisms is important for managing breeding and genetic improvement programs. Farmers should work with geneticists and breeders to develop effective breeding strategies that enhance the productivity and resilience of their livestock and crops. Knowledge of genetics will aid in optimizing breeding programs and improving farm performance.
