Does Foliar Zinc Application Boost Leaf Photosynthesis of ‘Wichita’ Pecan Fertigated with Zinc-EDTA?
Publikováno v:
HortScience, Vol 56, Iss 5, Pp 579-582 (2021)
Many growers fertigating their orchards with zinc–ethylenediaminetetraacetic acid (Zn-EDTA) are still using supplemental zinc foliar sprays because of a lack of confidence that soil-applied Zn-EDTA is supplying enough Zn to the trees. A field study

Pecan (Carya illinoinensis) has high kernel antioxidant activity and unsaturated fatty acid content, which contribute to its nutraceutical properties. In the western United States, where soils are typically alkaline, pecan trees require frequent zinc
