Size of irrigation norm count as a difference of stocks of the moisture corresponding to the smallest moisture capacity (NV) and 70-90 % for NV, taking into account factor of local moistening of the soil at a drop irrigation.
Tenziometra are simple on the technical device, are convenient in operation, rather inexpensive, and the principle of their work substantially corresponds to "work" of a root of a plant. Thanks to these useful properties tenziometry found very wide application both in scientific researches, and in practice of agricultural industry – for determination of humidity of the soil and diagnosing of terms of watering of crops.
The IGIM UAAN Crimean research center offers services in installation of sensors of humidity of the soil.
