Machine Utilization Rate

A performance metric representing the ratio of actual operating time to the total available time a machine is held within a farming operation over a specific pe...

Nutrition and fertilizers

Macronutrients

These are chemical elements required by plants in relatively large quantities to support growth, metabolic processes, and overall productivity.

Breeding and seed production

Male parent

The plant providing pollen for cross-pollination to produce new varieties or hybrid seeds.

Storage and economics

Marketability of grain

A quality indicator representing the proportion of primary grain in a batch that meets trade standards and is suitable for commercial sale.

Breeding and seed production

Mass selection

A breeding method where a group of plants with desirable phenotypic traits is selected from a population to produce seeds for the next generation without indivi...

Digital farming

Material flow control

This is the process of monitoring and regulating the volume of agricultural material passing through a technological line per unit of time.

Breeding and seed production

Maternal form

A plant used as the female parent in hybridization to produce seeds with specific desired traits or hybrid vigor.

Weather and climate

Maximum hygroscopicity

The maximum amount of moisture a dry soil can absorb from the atmosphere under saturation conditions, expressed as a percentage of the soil's dry weight.

Storage and economics

Maximum permissible losses

An economically justified level of crop loss where the cost of control measures does not exceed the value of the saved yield.

Sowing and varieties

Maximum permissible seeding rate

This is the highest seed density per unit area that ensures optimal crop development without inducing excessive intraspecific competition for nutrients, water,...

Nutrition and fertilizers

Microbiological fertilizers

Agricultural products containing live beneficial microorganisms that enhance plant nutrient uptake and suppress soil-borne pathogens.

Nutrition and fertilizers

Microgranules

Microgranules are a formulation of fertilizers or pesticides in the form of small particles, 0.5 to 2 mm in diameter, designed for precise, localized applicatio...

Nutrition and fertilizers

Micronutrients

Micronutrients are essential chemical elements, such as boron, zinc, and iron, required by plants in small quantities for healthy growth and physiological devel...

Growth and development

Milk-wax ripeness

A stage of cereal crop development where grain contents transition from a liquid to a dough-like consistency, marking the onset of moisture reduction.

Nutrition and fertilizers

Mineral nitrogen

Mineral nitrogen refers to the inorganic forms of nitrogen, primarily ammonium and nitrate, that are readily available for plant uptake from the soil.

Nutrition and fertilizers

Mineralization

The process by which soil microorganisms decompose organic matter into simple mineral forms that can be absorbed by plants.

Soil and tillage

Minimum tillage

A conservation tillage system that reduces the frequency and depth of mechanical soil disturbance to improve soil structure and moisture retention.

Weather and climate

Moisture coefficient

An indicator representing the ratio of annual precipitation to potential evapotranspiration, used to determine moisture availability for crop production.

Storage and economics

Moisture conversion factor

This is a mathematical factor used to adjust the weight of agricultural commodities to a standard moisture level for accurate storage and trade calculations.

Breeding and seed production

Morphological traits

These are the external physical characteristics of a plant, such as shape, size, color, and structure, used for variety identification and field assessment.

Soil and tillage

Mulching

Mulching is the agricultural practice of covering the soil surface with organic or inorganic materials to improve soil health and plant growth.

Machinery and irrigation

Multicontroller

A centralized electronic control unit that integrates the operation of various agricultural machinery components into a single interface.
