Abstract

Kmetijstvo je največji porabnik vode, saj porabi več kot 70 % sladke vode na svetu, zato je še toliko bolj pomembno, da se avtomatizirani namakalni sistemi razširijo po svetu in postanejo cenovno dostopni tudi manjšim kmetom. Z uporabo avtomatiziranega namakalnega sistema privarčujemo z vodo do 65 %, poleg tega pa zmanjšamo izpiranje hranil in sredstev za varstvo rastlin iz tal. Zaradi nepravilnega namakanja se izgubi do 50 % vode, z avtomatiziranim namakanje pa se njegovo produktivnost poveča za dvakrat. Avtomatiziran sistem deluje na podlagi algoritma, ki združuje razpored namakanja na osnovi vodne bilance s pomočjo meritev senzorjev, ki neprekinjeno merijo količino vode v tleh. Glavni komponenti avtomatiziranega namakalnega sistema sta terenska in programska oprema, kjer se po podatkih senzorjev za merjenje količine vode v tleh in podatkov vremenske postaje, izvede namakanje brez posega človeka. Za pravilno delovanje morajo biti meritve senzorjev kakovostne, na kar vplivajo hidravlične lastnosti tal, struktura korenin in lokacija senzorjev.

Secondary title: Automatic irrigation systems to reduce water consumption during irrigation
Secondary abstract: Agriculture is the largest consumer of water, consuming more then 70% of the world's available water, which is why automated irrigation systems must be spread around the world and become affordable to smaller farmers as well. Using an automated irrigation system that saves up to 65% water is also minimizing leaching losses from the substrate. Incorrect irrigation loses up to 50% of water, but with automated irrigation, its productivity is doubled. The automated system works based on algorithms that combine distributed irrigation based on a water balance using sensors that continuously measure the amount of water in the soil. The main components of the automated irrigation system are hardware and software, which is based on the date from sensors for measuring the amount of water in the soil and the data of weather stations, performed without human intervention. For the best results, measurements must be as correct as possible. Sensors measurement is affected by the hydraulic properties of the soil, the structure of the roots and the location of the sensors themselves.
