 For crops to make more yield, they need more nutrients faster. I'm Darren Hefty with Hefty Naturals. Much of a crop's yield is determined during reproductive stages, requiring lots of nutrients in a short window of time. Keep your nutrients moving with NewTek CDA. Five years of university trials show foliar applications of NewTek CDA provide an average yield increase of 10.8 bushels in corn and 2.7 bushels in soybeans. Don't let your crops get hungry. Harness the next generation of nutrient transporter technology with NewTek CDA.
