Crop protection
Latent infection
A state where a plant pathogen is present within plant tissues without causing any visible symptoms or damage.
Crop protection
Latent infection
A plant health state where a pathogen or pest is present in the tissues, but no visible symptoms of disease have yet appeared.
Sowing and varieties
Latent seed infection
The presence of pathogens within the seed tissues that cannot be detected by external inspection without specialized laboratory testing.
Nutrition and fertilizers
Layer-by-layer soil analysis
A method of soil testing where samples are collected from distinct depths separately to assess the vertical variation of chemical properties and nutrients withi...
Nutrition and fertilizers
Leaf analysis
A diagnostic method used to determine the nutrient status of plants by chemically analyzing their leaf tissue.
Growth and development
Leaf Area Index
A dimensionless measure of the total green leaf area per unit of ground surface area.
Growth and development
Leaf Area Index (LAI)
A dimensionless quantity that characterizes plant canopies as the ratio of one-sided green leaf area per unit ground surface area.
Sowing and varieties
Light regime
The combination of lighting characteristics, such as intensity, spectral quality, and photoperiod, that dictates the growth, development, and productivity of ag...
Growth and development
Light stage
A specific physiological phase in plant development where light duration and quality are required to trigger the transition from vegetative growth to flowering.
Nutrition and fertilizers
Liming
An agricultural practice of applying calcium-rich materials to soil to neutralize acidity and enhance overall soil fertility.
Machinery and irrigation
Linear move irrigation system
Agricultural irrigation equipment designed for rectangular fields that moves linearly across the area, drawing water from an open ditch or a flexible hose.
Machinery and irrigation
Liquid flow sensor
A technical device designed to measure the volume or velocity of liquid moving through the supply system of agricultural machinery.
Growth and development
Lodging
Lodging is the displacement of crop stems from their vertical position, resulting in the plants leaning or falling flat against the soil surface.
Machinery and irrigation
Low-pressure tires
These are specialized agricultural tires with a large footprint designed to reduce soil compaction and prevent heavy machinery from sinking into the ground.
