Macro-Sorb Foliar + Quelant-Minors Seedling Establishment Trial
Introduction: Seedling establishment of turfgrass is often challenging, particularly during the spring months. In order to have a successful establishment from seed, the turf plants need to mature quickly and increase density as quick as possible. A trail was established to evaluate Macro-Sorb Foliar + Quelant-Minors at improving turfgrass seedling establishment.
Materials & Methods: In this trial, tall fescue was seeded at a rate of 5 lbs/1000 ft2 into 4” pots consisting of a sandy loam soil. Starter fertilizer (15-23-10) was applied to all pots at 0.25 lbs. N/1000 ft2 during time of seeding. Pots were lightly watered 3 times daily until seed germinated, after germination, seedlings were watered once a day with 0.25” of irrigation. Seven days after germination, treatments (Table 1.) were foliar-applied to seedlings. Plants were either treated with Macro-Sorb Foliar + Quelant-Minors or left untreated. Both Macro-Sorb Foliar and Quelant-Minors were applied at 2.0 fl oz. per 1000 ft2. Seven days after the initial application (or 14 days after germination) Macro-Sorb Foliar was re-applied to treatment two. Plants were evaluated for establishment rate, density and turf quality (Figures 1-3).
Discussion: Turfgrass seedlings treated with Macro-Sorb Foliar + Quelant-Minors demonstrated an increase is density and quality just 3 days after application (Figure 1.). Three weeks after germination, seedlings treated with Macro-Sorb Foliar + Quelant-Minors had a much greater density, higher quality and greater maturity than untreated plants. Applications of Macro-Sorb Foliar and Quelant-Minors will greatly improve seedling establishment of turfgrass.
