Switchgrass (Panicum virgatum L.) is an important perennial energy crop. In this work, the uptake of NO -3-N by switchgrass as an index of soil quality improvement was studied in a pot experiment. Totally 24 pots with a peat-soil substratum of 1 kg were prepared receiving NO -3–N up to a concentration of 44 ppm. In half pots, a zeolite-bentonite 3:1 mix was added (total 10 gr per pot). Switchgrass variety Alamo was sown in...
