Lifting Unit: A lifting unit is a pair of wheels or a triangular-shaped share, used on a harvester to lift the roots and pass them to the main elevator. Also called lifter. The roots are lifted by being squeezed out of the ground in between the two wheels. The distance between the two wheels or shares can be adjusted to suit the size of the crop. The wheels should be set quite close together at the bottom when harvesting small roots. The wheels run at an angle to each other so that their rims lie close together when in the soil and farther apart at the top. Using lifting units can enhance the efficiency of harvesting root crops.

Lateral: A lateral is a shoot which branches off from the leader or main branch of a tree or shrub. Managing lateral growth helps farmers optimize fruit and nut tree productivity.

Land Drainage: Land drainage is the process of removing surplus water from land. If surplus water is prevented from moving through the soil and subsoil, it soon fills all the pore spaces in the soil and this will kill or stunt the growing crops. Well-drained land is better aerated, and crops are less likely to be damaged by root-destroying fungi. Aerated soil also warms up more quickly in spring. Plants form deeper and more extensive root systems, grassland is firmer, and disease risk from parasites is reduced. The main methods of draining land are underground pipe drains, mole drains, and ditches. Proper land drainage improves soil health and crop yields.

Lincoln Red: Lincoln Red is a breed of cattle bred from the shorthorn. The animals are deep red in color. The breed was originally dual-purpose, but now is mainly used for crossing with dairy cows to produce beef calves. Raising Lincoln Red cattle can provide farmers with high-quality beef and enhance farm profitability.

Lysimeter: A lysimeter is a device used for measuring the rate of drainage of water through soil and the soluble particles removed in the process. Using lysimeters can aid in effective water management and soil health monitoring.

Locust Bean: Locust bean is the broken-down pods of the carob tree, used as animal feed. Utilizing locust beans can provide a nutritious feed source for livestock.

Liquor: Liquor is a concentrated liquid substance. Rumen liquor, silage liquor. Managing liquor in feed and silage can improve livestock nutrition and fermentation processes.

Leasehold: Leasehold means possessing property on a lease, for a fixed time. To purchase a property leasehold. The property is for sale leasehold. Understanding leasehold arrangements can help farmers secure land and facilities for agricultural use.

Land Reform: Land reform is a government policy of splitting up agricultural land and dividing it up between those people who do not own any land. Land reform policies can increase access to land and promote equitable agricultural development.

Louse: A louse is a small wingless insect that sucks blood and lives on the skin as a parasite on animals and humans. There are several types, the commonest being body louse, crab louse, and head louse. Some diseases can be transmitted by lice. Genus: Pediculus. (NOTE: The plural is lice.) Managing lice infestations through proper pest control measures can protect livestock health and improve farm productivity.
