| Abstract/Contents: | States that "we initiated in 1985 several studies to look at ways to improve centipedegrass color without using more than 2.0 lb N/1000 ft2/year" and "our two approaches were: (a) use of iron either with or without N, (b) use of slow release N carriers to slowly release N over the whole season." States that "three Fe carriers and rates were selected and evaluated in 1986 alone and in combination with N" and "eight slow release N-carriers were compared to ammonium nitrate (a fast release N fertilizer) and no N (control)." Results for use of Iron (Fe) include: "the foliar application of only 0.80 lb N/1000 ft2 as urea caused some phytotoxicity by 4 days after application," "in combination with 0 or 0.20 lb N/1000 ft2 several Fe carriers/rates did not result in excessive phytotoxicity," "however when the Fe was applied with the 0.80 lb N/1000 ft2, most of the combinations resulted in excessive phytotoxicity" and "when evaluating the visual quality data, the visual quality of the first few days after treatment is most important because it reflects any phytotoxicity." Results for slow release N-carriers include "all carriers resulted in better quality and color than did the 0-N control," "when using ammonium nitrate, splitting the annual N into two equal portions resulted in as good or better quality and color during the season as any of the slow release N-carriers," "using a split application of ammonium nitrate (i.e. 1+1), resulted in as good or better quality and color during the season as any of the slow release N-carriers," "of the slow release N-carriers, the best quality and color were observed for Escote 200, Escote 100, and IBDU (coarse), while ureaform was least effective" and "the SCU (coarse) provided better season long quality and color than the SCU + AN combination." |
