A non-electronic instrument that measures how ‘hard’ it is for water to move in the soil (water tension).

Use heat accumulators, in the form of water or molten salt tanks, to allow the storage of energy for heating.

The initial expense to purchase and install the system, often high but with long-term savings.

Technique that applies fertilisers in different quantities according to the specific needs of each area of the field.

A value (e.g., NDVI, EVI) calculated from spectral data to assess plant health.

Physical phenomenon in which a moving fluid creates a vacuum that ‘sucks in’ another liquid (e.g. the fertiliser solution).

The difference between water input and output in a system (e.g., soil, farm).

Monitoring the amount of water used, to save and optimise costs.

A sensor worn by animals (e.g., on a collar or ear tag) to monitor their health, activity, or reproductive cycle.

The amount of energy produced depends on the sun, wind or rain, so it is not always stable
