Evapotranspiration (ET) is defined as the amount of water that is transferred to the atmosphere by the phenomena of direct evaporation from the soil and vegetation (interception) and transpiration of vegetation.
We speak of actual evapotranspiration when it represents the actual amount of water that is transformed into vapour by the combination of atmospheric factors and vegetation. Unlike potential evapotranspiration, real evapotranspiration depends on the water content of the soil in addition to climatic factors (temperature, wind, relative humidity, etc.).

Irreo is the only service that can distinguish between foliar transpiration and soil evaporation. Distinguishing between soil evaporation and foliar water consumption allows you to implement different irrigation strategies with respect to crop type and phenological status.

Vigour index

daily update, depending on cloud cover
The vigour index (NDVI) describes the level of vigour of the crop and is calculated as the ratio between the difference and the sum of the reflected near-infrared and red radiation.
The interpretation of the absolute value of the NDVI makes it possible to immediately recognise the areas of the field that show development problems.
The NDVI is a simple index to interpret. Values can vary between 0 and 1, each value corresponding to a different agronomic situation.

The NDVI is a simple index to interpret. Values can vary between 0 and 1, each value corresponding to a different agronomic situation.
The average NDVI of a field varies according to the variety and phenological stage of the crop. In the same field or in adjacent fields in which a crop is at the same phenological stage, areas in which the NDVI value is significantly lower than the average show problems in vegetative development, which can be caused by quite different factors such as:
- nutritional stress;
- parasite attacks;
- heavy hail or frost damage;
- low emergency.
To identify potential problem areas in each field, we identify the minimum and maximum NDVI value in the field.
The field is then recoloured on the map by associating brown colour with the minimum value, and green colour with the maximum value.

Leaf area index (LAI) is one of the main biophysical variables of vegetation and represents the ratio of square meters of foliage per square meter of soil (m²/m²). Irreo uses LAI estimation and its spatial distribution to define the phenological status of the culture, monitor crop growth, estimate yield, and monitor vegetation stress in order to suggest best practices for irrigation management.

Leaf cover index (FVC) is an important indicator of the degree of greenness of the crop and has a strong correlation with biomass. This parameter represents the fraction of the soil area covered by green foliage in the two-dimensional plane, and is expressed as a percentage.
Irreo uses this parameter to separate vegetation from soil in energy-balance processes, including temperature and evapotranspiration, and for characterization of crop growth status throughout the season to optimize precision irrigation management.

Chlorophyll content (CCC) is an excellent indicator of stress, including nitrogen deficiencies. It is strongly related to leaf nitrogen content and is expressed in milligrams per square centimeter (mg/cm²). This quantity can be calculated at both leaf and canopy level by multiplying leaf chlorophyll content by leaf area index.

Crop canopy water content (CWC) is an essential indicator of crop physiological status. Leaf water potential, expressed in milligrams per square centimeter (mg/cm²), and relative water content are important variables in determining water deficit and drought effects.
Soil moisture index

The soil moisture index (NSMI) represents the current soil moisture relative to the permanent wilting point and field capacity.
Index values range from 0 to 1, with 0 indicating extreme dry conditions and 1 indicating extreme wet conditions. It can be used before planting to check for drainage problems in the soil.

How does the satellite data work?
The sun emits radiation with different wavelengths and frequencies. The electromagnetic spectrum (EM spectrum) denotes the set of all possible frequencies of electromagnetic radiation. The entire spectrum is divided into the visible spectrum part, which originates light, and the non-visible spectrum parts with wavelengths longer or shorter than the visible spectrum.
Vegetation absorbs solar radiation in different bands, that is, in different frequency ranges and wavelengths, and re-emits a different percentage of it in each. The percentage of re-emitted radiation in specific bands, such as those of near infrared (NIR), red (RED), and short wave infrared (SWIR), indicates plant health or water stress.
