D

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.
