| dc.description.abstract | Three popular brand name fertilizers, Scotts, Agrico,
and Milorganite, and a Urea plus Potassium Chloride mixture
were applied to a Kentucky bluegrass. Fertilizers were
applied at a rate of 1 pound of actual nitrogen per 1000 ft^2.
Three weeks following fertilizer application, grass cuttings
occurred at 3 consecutive 3-week intervals. Fertilizer
response was measured by weighing grass clippings to determine
yield and analyzing grass tissue to determine nitrogen,
phosphorus and potassium uptake.
Analysis of variance indicated no significant difference
from one cutting to the next for yield, nitrogen, and phosphorus
uptake. Potassium uptake did vary significantly from
one period to the next. The study shows a statistically significant
difference.
Scotts, Agrico and Urea plus Potassium Chloride mixture
were equally effective in producing yield and supplying
nutrients. Milorganite, the only organic fertilizer tested,
was not effective.
Performance and price are the two most important factors
in selecting a fertilizer. Based on these two factors, the
Urea plus Potassium Chloride mixture proved to be the best
buy in this study. | en_US |
