Abstract
Istraživanje je postavljeno na pokušalištu Tenja, Fakultetu agrobiotehničkih znanosti Osijek. U nasadu jabuke su postavljena dva tipa senzora, odnosno Watermark senzor koji radi na principu elektrometrije te tenziometar koji radi na principu tenziometrije. Prije postavljanja u tlo, senzori su pripremljeni prema uputama proizvođača te je izrađena krivulja umjeravanja koja je služila za interpretaciju dobivenih podataka, odnosno za određivanje trenutka početka navodnjavanja. Količina oborine tijekom svibnja i lipnja su zadovoljile potrebu biljaka za vodom, odnosno nije bilo potrebe za navodnjavanjem. Tijekom mjeseca srpnja je ukupno dodano 454 mm u jedanaest obroka navodnjavanja. Tijekom mjeseca kolovoza je ukupno dodano 156 mm u četiri obroka navodnjavanja. Oba senzora su dobro reagirali na izmjene vlažnosti tla, posebice u gornjem sloju profila tla, odnosno na dubini od 20 cm i 30 cm gdje je i očekivana najveća dinamika vlažnosti. Obrocima navodnjavanja je uspješno sadržaj vode u tlu održavan na razini od 60 (80) do 100 % poljskog vodnog kapaciteta. Analiza korelacijske povezanosti između Watermark senzora i tenziometra je pokazala vrlo jaku statistički opravdanu (p < 0,01) povezanost (r = 0,8).
Abstract (english)
The research was set up at the Tenja experimental site of the Faculty of Agrobiotechnical Sciences, Osijek. Two types of sensors for measuring soil water content were placed in the apple orchard, namely the Watermark sensor that works on the principle of electrometry and the tensiometer that works on the principle of tensiometry. Before placing the sensors in the soil, they were prepared according to the manufacturer's instructions, and a calibration curve was created that was used to interpret the obtained data, i.e. to determine the irrigation time. The amount of precipitation during May and June satisfied the plants' need for water, that is, there was no need for irrigation. During the month of July, a total of 454 mm was added in eleven irrigation events. During the month of August, a total of 156 mm was added in four irrigation events. Both sensors responded well to changes in soil moisture, especially in the upper layer of the soil profile, that is, at a depth of 20 cm and 30 cm, where the highest dynamics of moisture are expected. With irrigation rates the soil water content was successfully maintained at the level of 60 (80) to 100% of the field's water capacity. The correlation analysis between the Watermark sensor and the tensiometer showed a very strong statistically justified (p < 0.01) correlation (r = 0.8).
