Abstract :

The study was conducted over two years at INCDA–Bottom from Romania to the wheat crop. There were used complex chemical fertilizers NPK based and controlled release fertilizers (CRF). The experimental variants were: V1 = N0P0K0; CRF V2 = 60 kg / ha + 40 kg / ha N; CRF V3 = 80 kg / ha + 40 kg / ha N; V4 = N120P80K40. The experimental results showed that the use of the controlled release of fertilizers CRF in a dose of 80 kg / ha + combined with 40 kg / ha N were obtained production of 5682.50 kg / ha with 158.0% more compared to the control. These findings identify mechanisms through which drought–induced changes in root systems affect soil C and N availability, and contribute to our understanding of how root traits modify soil processes in a changing world.
