distribution: The spreading of something over an area. Proper distribution of seeds, fertilizer, or pesticides is important for achieving uniform application and optimal results. Farmers should use appropriate equipment and techniques for effective distribution. Understanding the benefits and applications of distribution will aid in effective crop and soil management.

defoliate: To make the leaves fall off a plant, especially by using a herbicide or as the result of disease or other stress. Defoliation can be a management tool or a sign of plant stress. Farmers should monitor crops for signs of disease or environmental stress and take appropriate actions to mitigate defoliation. Using defoliants judiciously can help manage crop canopies and improve harvest efficiency. Regular scouting and timely interventions will ensure healthy crop growth and productivity.

doubles: Twins of animals, especially lambs. Managing doubles requires careful attention to ensure both offspring receive adequate nutrition and care, maximizing their chances of survival and healthy growth.

double digging: A cultivation technique where a spit is dug out, the soil placed on one side, and a second spit dug. This loosens the soil at a deeper level than normal digging. Double digging improves soil aeration and fertility, promoting healthier plant growth.

distillation: The process of purifying a liquid by heating it so that it becomes a gas and then condensing it to form a pure liquid again. Distillation is an important process for producing high-quality products like essential oils and spirits. Farmers should use appropriate equipment and techniques for effective distillation. Understanding the benefits and applications of distillation will aid in optimizing production and product quality.

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.
