Погода и климат

Radiation balance

Radiation balance is the difference between the total solar radiation absorbed by the earth's surface and the effective outgoing radiation emitted by it.

Погода и климат

Relative humidity

It is the ratio of the actual amount of water vapor in the air to the maximum amount the air could hold at a specific temperature, expressed as a percentage.

Рост и развитие

Remontancy

The ability of plants to produce multiple crops or bloom continuously throughout a single growing season.

Цифровое земледелие

Remote field monitoring

A set of technologies involving satellite imagery, aerial photography, or drones to observe and analyze crop conditions and field development remotely.

Цифровое земледелие

Remote Sensing of the Earth

This is a method of gathering information about crops and soil conditions using satellites, drones, or aircraft without direct physical contact with the field.

Селекция и семеноводство

Reproduction

This is a successive generation of seeds or planting material obtained during the process of seed production from initial plant forms.

Селекция и семеноводство

Reproduction sowing

A method of sowing elite or high-generation seeds to produce quality seed material for future cycles while preserving the variety's specific traits.

Рост и развитие

Reproductive phase

The developmental stage of a plant during which reproductive organs are formed, leading to flowering, pollination, and seed or fruit development.

Посев и сорта

Reseeding (gap filling)

An agronomic practice of sowing additional seeds in areas with thin or failed emergence to achieve the optimal plant population density.

Защита растений

Residual activity period

The duration of time during which a pesticide remains biologically active to protect crops against target pests or diseases.

Защита растений

Residual effect

The impact of fertilizers or pesticides applied in previous seasons on the current crop growth and soil characteristics.

Хранение и экономика

Residual moisture

The amount of water remaining in soil or agricultural produce after natural drying, evaporation, or drainage processes have occurred.

Рост и развитие

Respiration rate

Respiration rate is the speed at which a plant or harvested produce consumes oxygen and releases carbon dioxide through metabolic processes.

Защита растений

Retardant

Retardants are plant growth regulators that inhibit stem elongation, helping to produce shorter, thicker, and stronger stems to prevent lodging.

Селекция и семеноводство

Roguing

The practice of identifying and removing off-type plants, diseased individuals, or weeds from a crop to maintain genetic purity.

Питание и удобрения

Root exudates

These are organic compounds released by plant roots into the soil, creating a nutrient-rich environment for beneficial soil microorganisms.

Питание и удобрения

Root feeding

This is a method of applying fertilizers directly into the soil within the reach of a plant's root system.

Питание и удобрения

Root nutrition

Root nutrition is the process by which plants absorb water and essential mineral nutrients from the soil through their root system.

Рост и развитие

Root pressure

The active force generated by plant roots that pushes water and dissolved minerals upward through the xylem vessels, ensuring nutrient transport independently o...

Питание и удобрения

Root system

The entire network of roots belonging to a single plant, responsible for anchoring the plant in the soil and absorbing water and essential nutrients.

Техника и орошение

Row spacing

The distance between adjacent rows of plants in a field or crop plantation.

Посев и сорта

Row spacing

The distance between adjacent rows of plants during sowing or planting, measured between the center lines of the rows.

Техника и орошение

RTK Base Station

A terrestrial receiver that transmits corrections to agricultural machinery to enable centimeter-level accuracy for satellite navigation systems.

Цифровое земледелие
