An official catalogue of plant varieties approved by the government for commercial cultivation and sale within a country.

Хранение и экономика

Natural mass

The actual weight of agricultural products as measured at the point of receipt or sale, regardless of moisture content or purity levels.

Цифровое земледелие

NDVI (Normalized Difference Vegetation Index)

A remote sensing indicator used to quantify crop health and density by measuring the difference between near-infrared and red light reflectance.

Хранение и экономика

Negative allowance

A method of reducing the seed sowing rate based on superior seed quality, such as high laboratory germination and Thousand Kernel Weight (TKW).

Питание и удобрения

Nitrification

The biological process of oxidizing ammonia nitrogen by soil bacteria into nitrate, which is the form most easily absorbed by plants.

Питание и удобрения

Nitrogen fixation

The process by which atmospheric nitrogen is converted into ammonia or related nitrogenous compounds that plants can use.

Питание и удобрения

Nitrogen immobilization

The process by which soil microorganisms absorb mineral nitrogen, temporarily making it unavailable for uptake by crop plants.

Цифровое земледелие

Nitrogen sensor

An agricultural device that measures nitrogen levels in soil or crop canopy to assist in precision nutrient management.

Питание и удобрения

Nitrogen top dressing

Nitrogen top dressing is the application of nitrogen fertilizers during the growing season to promote healthy vegetative growth and increase crop yields.

Питание и удобрения

Nitrogen-fixing bacteria

Microorganisms capable of transforming atmospheric nitrogen into a form that plants can easily absorb and use for growth.

A replaceable component of a sprayer designed to atomize liquid into droplets of a specific size and create a spray pattern for uniform pesticide or fertilizer...

Техника и орошение

Nozzle

A mechanical device used in sprayers to atomize liquid into droplets and distribute it evenly over a target area.

Техника и орошение

Nozzle

A nozzle is a precision-engineered tip attached to a sprayer that regulates the flow of liquid and breaks it into droplets of a specific size and pattern.

Техника и орошение

Nozzle working pressure

The pressure at which the liquid is forced through the nozzle, determining droplet size, spray pattern, and flow rate.

Питание и удобрения

NPK

Азот–Фосфор–Калий — основные элементы минерального питания.

Питание и удобрения

NPK complex

This is a balanced combination of the three primary macronutrients — nitrogen, phosphorus, and potassium — essential for optimal plant growth and crop yield.

Питание и удобрения

Nutrient balance

This is the net difference between the amount of nutrients applied to the soil through fertilizers and the amount removed from the field by crop harvest.

Питание и удобрения

Nutrient deficiency

A condition in which a plant does not receive sufficient essential nutrients from the soil or fertilizers to support its healthy growth and development.

Питание и удобрения

Nutrient uptake

This is the amount of mineral nutrients that crops absorb from the soil and fertilizers to produce their total biomass and yield.

Питание и удобрения

Nutrient Use Efficiency

This is a measure of the proportion of nutrients actually taken up by the plant from applied fertilizers relative to the total amount applied.
