droppings board: A bench under the perches in smaller poultry houses, on which bird droppings collect. Droppings boards help keep poultry houses clean and make it easier to collect and manage manure.

Derbyshire Gritstone: A black-faced, hornless hardy breed of sheep, which produces a soft fleece of high quality. The name comes from a type of rock, millstone grit, found in the Peak District of Derbyshire. Farmers raising Derbyshire Gritstone sheep should focus on proper grazing management, regular shearing, and health monitoring to maintain flock productivity. Marketing the unique characteristics of Derbyshire Gritstone wool can attract premium buyers and enhance farm profitability.

disk: Alternative spelling of disc. A circular agricultural implement used for tillage and soil preparation. Using disks can improve soil preparation and root penetration for crops. Farmers should select the appropriate type of disk for their needs and use it properly to achieve optimal soil conditions. Understanding the benefits and applications of disks will aid in effective soil management and crop establishment.

disclimax: The most stable community of plants and animals that an area can support, occurring as a result of disturbance. Understanding disclimax is important for managing ecosystems and maintaining biodiversity. Farmers should implement sustainable land management practices to support stable and resilient plant and animal communities. Understanding the factors contributing to disclimax will aid in developing effective conservation and management strategies.

dendrochronology: A scientific method of finding the age of wood by the study of tree rings. Dendrochronology can provide valuable information about tree growth patterns, climate history, and forest management. Farmers and foresters can use dendrochronology to understand the age and health of trees, aiding in sustainable forest management practices. Knowledge of dendrochronology can also support research and conservation efforts.

drawbar: A metal bar at the back of a tractor used to pull trailed implements. Some tractors have a drawbar that can be attached to the hydraulic linkage. Drawbars are essential for connecting various types of farm equipment.

dairy farm: A farm which is principally engaged in milk production. COMMENT: The UK is Europe’s 3rd largest milk producer, and is limited to an annual production quota of 14.2 billion litres. Although it is largely self-sufficient in milk, related products such as cheese, milk powder, cream and butter are heavily imported and exported between the UK and other EU countries. Running a successful dairy farm requires knowledge of animal husbandry, nutrition, milking technology, and farm management. Farmers should stay updated with the latest research and technology in dairy farming to improve milk production and ensure sustainable practices. Networking with other dairy farmers and attending workshops can provide valuable insights and support.

dry-stone wall: A wall made of stones carefully placed one on top of the other without using any mortar. Dry-stone walls are traditional structures that provide boundaries and shelter on farms and require regular maintenance to remain effective.

diffuse water pollution: Water pollution which is caused by several small sources such as runoff from farms. Managing diffuse water pollution involves implementing practices like buffer strips, cover cropping, and proper nutrient management. Farmers should adopt measures to reduce runoff and prevent contaminants from entering water bodies. Understanding the sources and impacts of diffuse water pollution will aid in developing effective water management strategies.

dairyman: 1. A person who works with dairy cattle. 2. A person employed in a commercial dairy. Dairymen are skilled workers who manage dairy cows and milk production. Proper training in animal care, milking procedures, and dairy management can lead to better milk yields and healthier cows. Farmers should provide ongoing education and support for their dairymen to ensure they have the skills needed to maintain high standards of dairy farming.
