Leaf Blotch

Leaf Blotch: Leaf blotch is a disease of cereals (Rhynchosporium secalis) where dark grey lesions with dark brown margins occur on the leaves. Managing leaf blotch through disease prevention and control measures can protect cereal crops and improve yields.

Lymph

Lymph: Lymph is a colorless liquid containing white blood cells, which circulates in the body, carrying waste matter away from tissues to the veins. It is an essential part of the body’s defense against infection. Understanding lymph and its role in the immune system can aid in managing livestock health.

L

Leek

Leek: Leek is a hardy winter vegetable (Allium ameloprasum) with a mild onion taste. To produce high-quality leeks, the lower parts of the stems need to be blanched. The stems are used in soups and stews. Growing leeks can provide farmers with a nutritious and versatile crop for market sales.

Lambing Season

Lambing Season: Lambing season is the period of the year when a flock of ewes produces lambs, usually between December and January. The object is to produce lambs for the market when the price is highest, usually between February and May. Timing lambing season correctly can maximize profits for farmers.

L

Lamb Dysentery

Lamb Dysentery: Lamb dysentery is a bacterial disease which enters the lamb from the pasture. The bacteria infects the land for a very long time. The disease can be avoided by vaccinating the lambs as soon as possible after birth or by vaccinating the ewes before lambing. Understanding and preventing lamb dysentery can save farmers from significant livestock losses.

L

Lehmann System

Lehmann System: Lehmann system is a system of pig breeding developed in Germany, where bulk food such as potatoes and fodder beet are fed after a basic ration of meal. Implementing the Lehmann system can optimize pig nutrition and improve breeding outcomes.

L

Locust

Locust: A locust is a flying insect which occurs in subtropical areas, flies in large groups, and eats large amounts of vegetation. Managing locust infestations through pest control measures can protect crops and ensure farm productivity.

L

Light Leaf Spot

Light Leaf Spot: Light leaf spot is a disease (Pyrenopeziza brassicae) which affects oilseed rape, causing light green or pale areas to appear on the leaves. Managing light leaf spot through disease prevention and control measures can protect oilseed rape crops and improve yields.

L

Ladybird

Ladybird: Ladybird is a beetle of the Coccinellidae family, which is useful to the farmer because it feeds on aphids which would damage plants if they were not destroyed. (NOTE: The US term is ladybug.) Encouraging ladybirds can be a natural pest control method, reducing the need for chemical pesticides.

L

Larch

Larch: Larch is a deciduous European softwood tree that has cones. It is fast-growing and used as a timber crop. Genus: Larix. Growing larch trees can provide farmers with a sustainable source of timber.

L

Lynchet

Lynchet: Lynchet is 1. a strip of land formed as the result of a movement of soil down a slope as a result of cultivation. Negative lynchets form at the top of the slope and positive lynchets at the bottom. 2. an unploughed strip of land forming a temporary boundary between fields. Lynchets on former prehistoric fields can still be seen in the form of steps on the sides of hills. Understanding lynchets and their formation can aid in effective land management and erosion control.

L

Land Suitability

Land Suitability: Land suitability is the suitability of land for a certain agricultural purpose. Land suitability is similar to land capability but defines its usefulness for a particular purpose. Suitability tends to emphasize the positive value of land, while capability emphasizes its limitations. Assessing land suitability helps farmers choose appropriate crops and farming methods.

L

Ley

Ley: A ley is 1. a field in which crops are grown in rotation with periods when the field is sown with grass for pasture. Leys are an essential part of organic farming. 2. land which has been sown to grass for a time. Utilizing leys in crop rotation can improve soil health and fertility.

L

Lush

Lush: Lush refers to vegetation which is thick and green. The cattle were put to graze on the lush grass by the river. Lush tropical vegetation rapidly covered the clearing. Managing lush vegetation can enhance pasture quality and livestock nutrition.

L

Leach

Leach: To leach means to be washed out of the soil by water. Excess chemical fertilizers on the surface of the soil leach into rivers and cause pollution. Nitrates have leached into groundwater and contaminated the water supply. Managing leaching through proper fertilizer application can protect water quality and soil health.

L

Layering

Layering: Layering is 1. a method of propagation where the stem of a plant is bent until it touches the soil, and is fixed down on the soil surface until roots form, and 2. a process by which the half-cut stems of hedge plants are bent over and woven around stakes set in the ground to form a new hedge. Utilizing layering techniques can enhance plant propagation and hedge formation.

L

Louse Disease

Louse Disease: Louse disease is an external parasitic disease of cattle. Severe infection leads to loss of condition, wasting, and anemia. Managing louse disease through proper treatment and prevention measures can protect cattle health and productivity.

L

Lysine

Lysine: Lysine is an essential amino acid in protein foodstuffs, essential for animal growth. Understanding amino acids like lysine can help farmers formulate balanced animal feeds and manage livestock nutrition.

L

Limestone

Limestone: Limestone is a common sedimentary rock, formed of calcium minerals and often containing fossilized shells of sea animals. It is porous in its natural state and may form large caves by being weathered by water. It is used in agriculture and building. Limestone is formed of calcium minerals and often contains fossilized shells of sea animals. It is an important source of various types of lime. Utilizing limestone can improve soil health and fertility, supporting crop growth.
