 Macro-Sorb Foliar + Quelant-Minors Seedling Establishment Trial

Seedling Study (3)

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.
