degressivity: A proposed reduction in the amount of subsidies paid under the CAP. This proposal was rejected as a method of keeping the CAP budget under control. Understanding subsidy policies and their impacts on farm income is important for financial planning. Farmers should stay informed about changes in subsidy programs and explore alternative income sources to ensure economic stability. Adapting to policy changes and diversifying farm activities can mitigate the effects of reduced subsidies.

dove: A white domesticated pigeon. Doves are often kept for ornamental purposes and as pets. Proper care includes providing adequate shelter, nutrition, and protection from predators.

dieback: A fungal disease of some plants which kills shoots or branches. A gradual dying of trees starting at the ends of branches. Half the trees in the forest are showing signs of dieback. COMMENT: There are many theories explaining the environmental cause of dieback. Sulphur dioxide, nitrogen oxides, and ozone have all been suggested as causes, as well as acidification of the soil or acid rain on leaves. Managing dieback involves implementing proper disease control, monitoring, and care practices. Farmers and foresters should identify the cause of dieback and take corrective actions to maintain tree health. Understanding the environmental factors contributing to dieback will aid in developing effective management strategies.

dioecious: Referring to a plant species in which male and female flowers occur on different individuals. Monoecious. Understanding dioecious plant species is important for managing pollination and fruit production. Farmers should implement proper planting and pollination practices to ensure successful crop yields. Knowledge of plant reproductive systems will aid in effective cultivation and management practices.

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.

disinfection: The removal of harmful organisms such as bacteria, viruses, or fungi from a place or an object by cleaning it with a disinfectant. Proper disinfection practices are essential for maintaining farm hygiene and preventing disease outbreaks. Farmers should implement regular disinfection routines and use appropriate techniques for effective disinfection. Understanding the benefits and applications of disinfection will aid in maintaining a healthy and productive farm environment.

discus: The method used to identify the structure of a species. Understanding discus methods is important for identifying species and managing soil health. Farmers should work with soil scientists and agronomists to perform accurate soil analysis and make informed decisions about soil management. Understanding the benefits and applications of discus methods will aid in effective soil management and crop production.

drone: A male bee. Drones do not gather nectar or pollen but are essential for mating with the queen. Beekeepers should manage drone populations to maintain a healthy hive.

diversion: The practice of changing the direction of water flow for irrigation or drainage. Managing water diversion is important for optimizing water use and preventing soil erosion. Farmers should use appropriate techniques and equipment for effective diversion. Understanding the benefits and applications of diversion will aid in effective water management and crop production.

drought: A prolonged period of abnormally low rainfall. Farmers need to manage water resources effectively to mitigate the impacts of drought.
