A slow-release nitrogen fertilizer developed for the <br /> turfgrass industry was used on all fertilized plots. The material is a proprietary <br /> form of granular urea formaldehyde sold as Blue Chip Nitrofocm by Nor-Am <br /> Chemical Co. This product is 38 percent total nitrogen(elemental basis). The <br /> material was broadcast evenly by hand over each plot to be fertilized in accordance <br /> with the study design. Application rate was 50 lb/acre elemental N. The advantage <br /> of this type of fertilizer is that it will not provide a large initial release of available <br /> nitrogen in the soil. The urea formaldehyde is gradually converted to an available <br /> form of nitrogen by soil bacteria. <br /> SEED m xTURE. The seed mixture shown in the following table was sown on all <br /> plots. Small lots of seed were obtained with the assistance of Wendell Hassell of <br /> the U.S.D.A. Soil Conservation Service. The mixture contains five grasses and <br /> one legume. Germination and purity test data were not available for all species, so <br /> seeding rates were not calculated on a Pure Live Seed basis. A relatively high bulk <br /> seeding rate(in terms of seeds per square foot)was used to accommodate <br /> anticipated low germination and establishment by some of the grass species. Seed <br /> for each plot was weighed to the nearest 0.1 gram. Seed was evenly broadcast over <br /> each plot by hand and lightly raked <br /> Table 1.
