Christina Sze, Benjamin Wang, Jiale Xu, Juan Rivas-Davila, and Mark A., Cappelli

TL;DR
This study explores plasma-fixated nitrogen as an innovative fertilizer for turf grass, demonstrating its effectiveness and potential advantages over traditional nitrate sources through experimental comparisons.
Contribution
It introduces plasma-fixated nitrogen as a novel fertilizer source and evaluates its efficacy relative to conventional nitrate fertilizers in turf grass growth.
Findings
Plasma-fixated nitrogen enhances turf grass growth more effectively than NaNO3 and KNO3.
Adding P and K to plasma nitrates improves grass biomass.
Growth depends strongly on nitrate concentration.
Abstract
We investigated the use of plasma-fixated nitrogen, which produces nitrates (NO3-) in water, as a possible nitrogen fertilizer for recreational turf such as ryegrass and bentgrass. Experiments were carried out to study the effects of nitrate concentration on growth, the further effects of adding phosphorous (P) and potassium (K) to the plasma nitrated solution to make an N-P-K complete fertilizer, and to compare the efficacy of plasma-fixated nitrogen to sodium nitrate (NaNO3) and potassium nitrate (KNO3). The results indicate that the growth and biomass of the plants were strongly dependent on the concentration of the plasma-fixated nitrogen. Adding P-K to the plasma-fixated nitrogen improved grass growth. Grass that was supplied plasma-fixated nitrogen had improved growth compared to those supplied with equal amounts of NaNO3and KNO3. This work highlights the potential use of…
