Lodgepole Pine: Lodgepole pine is a slow-growing tree which thrives on poor soil and is used as a pioneer crop (Pinus contorta). Growing lodgepole pine can provide farmers with a sustainable source of timber and improve soil health.

Legume: Legume is 1. a member of the plant family that produces seeds in pods, e.g., peas and beans. Family: Leguminosae. 2. a dry seed from a single carpel, which splits into two halves, e.g., a pea. There are many species of legume, including trees, and some are particularly valuable because they have root nodules that contain nitrogen-fixing bacteria. Such legumes have special value in maintaining soil fertility and are used in crop rotation. Peas, beans, clover, and vetch are all legumes. Utilizing legumes in crop rotation can enhance soil health and reduce the need for chemical fertilizers.

Leaf Cutting: A leaf cutting is a piece of a leaf, root, or stem cut from a living plant and put in soil where it will sprout. Using leaf cuttings for propagation can help farmers multiply plants efficiently.

Let-Down: Let-down refers to the let-down of milk, the release of milk from the mammary gland. The hormone oxytoxin activates the release of milk. The let-down lasts between seven and ten minutes, when the extraction of milk from the udder is easiest. Understanding the let-down process helps dairy farmers optimize milking efficiency.

Leaf Area Index: Leaf area index is the area of green leaf per unit area of ground. Abbr LAI. Monitoring leaf area index can help farmers assess crop health and optimize irrigation and fertilization.

Liquid Fertilizer: Liquid fertilizer is a simple solution, not kept under pressure, of the normal raw materials of solid fertilizers, as opposed to pressurized solutions such as aqueous ammonia. Utilizing liquid fertilizers can improve nutrient delivery and crop growth.

Loam: Loam is 1. dark soil, with medium-sized grains of sand, which crumbles easily and is very fertile, and 2. a mixture of clay, sand, and humus, used as a potting compost. Utilizing loam can improve soil health and crop growth.
