The issue of emitter clogging is a common phenomenon in drip fertigation systems, which causes uneven irrigation and fertilization. However, efficient environmentally friendly methods are scarcely available for alleviating clogging. In the present study, we investigated anti-fouling efficacy three magnetic field strength levels (0, 0.4 T 0.6 T) on systems. Our results show that magnetized water...

Nitrogen mobilization, nitrogen uptake and growth of cuttings obtained from poplar stock plants fertigated with different nitrogen (N) treatments and sprayed with urea in autumn were studied. Stock plants propagated from poplar cuttings were trained to a single shoot and fertigated with 0, 5, 10, 15 or 20 mmol l(-1) N during the first growing season. In October, a subset of stock plants from ea...
