The basis of effective agriculture is correct irrigation, taking into
account a huge set of indicators: climatic conditions, soil type,
features of moisture absorption, rate of evaporation, plant species,
growth stages, length of root penetration and many others.
Watering according to the degree of drying of the soil layers, which
is determined "by eye" or according to the norms of water consumption
of plants, does not take into account important indicators, depends on
the human factor and can neither contribute to the saving of resources
nor influence the productivity of the crop.
