nanoparticles, derived from natural minerals, into nanosized mesoporous spheres. These tiny silica-based spheres (30-100 nm), with meso- sized pores and channels, function as carrier molecules; their porous structure and negative charge allows for the loading and encapsulation of smaller charged molecules. After entrapping a payload within their mesoporous channels, these nanoparticles are actively taken up into plants, more effectively delivering those inputs than conventional methods allowing turfgrass managers to deliver expensive inputs more efficiently.
RESEARCH FINDINGS
Research was conducted at Texas A&M University to measure nutrient uptake responses into turfgrass when the liquid nanotechnology
product NanoCharge was added to a spray solution. At issue is the poor nutrient uptake inefficiencies of traditional foliar fertilizer applications.
Prior turfgrass research estimates creeping bentgrass putting green turf has only 31-56% foliar N uptake (from a 5 g N/m2 application) within 8 hours of application, with little more occurring thereafter (Steigler et al., 2013; Chang et al., 2020). Improving nutrient uptake with nanotechnology can help turfgrass managers: optimize plant health, save money, and reduce environmental losses. This study used 15N-labeled urea (0.2 lb. N/ 1000 sq. ft.) paired with a micronutrient solution to track, recover and compare plant uptake. These nutrient solutions were applied tocreepingbentgrassfoliageeither with or without NanoCharge at 0.2
oz/1000 sq.ft. (8.7oz per acre). After applying, turf samples were analyzed for percent differences between those fertilizers treated with NanoCharge vs. the fertilizer alone.
Results showed a significant increase in nitrogen, phosphorus, and calcium uptake in the turfgrass, which received NanoCharge in the spray solution. These results were the first to quantify the benefits of NanoCharge as a technology for improving nutrient uptake and use efficiencies on turfgrass.
In summary, nanoparticles have emerged as a revolutionary tool, offering a multitude of functional applications today and on the horizon to address some of the most pressing challenges in many industries, now including professional turfgrass management.GM
