The agronomic response of IBDU is compared to other nitrogen reaction products in Figure 4. In this study, various products were apphed to Kentucky bluegrass at 3 lb N /M (14.6 g/m ). Plant growth as measured by leaf fresh weight was monitored weekly.

In turf apphcations, SCU, with or without wax sealant, provides improved safety and longevity over urea. This is shown ia Figure 5 which rates the quahty of Kentucky bluegrass with time after being treated with 2 lb N/1000 sq ft (9.76 g/m ) of urea and two types of SCU. In this particular test, a quahty rating of 3 or less is acceptable. Urea provided acceptable turf quahty for 11 weeks, whereas the two SCU products (37% nitrogen) gave quahty turf for 16 weeks.

Cover designs The capillary barrier test section was installed in November 1999. From the surface downward, it is composed of 6 in. of topsoil, 18 in. of moderately compacted silt, and 24 in. of sandy gravel. The cover was seeded in March 2000 with a mixture of grasses, forbs, and shrubs, including bluegrass, wheatgrass, alfalfa, and prickly rose shrubs. A conventional composite cover test section was also constructed at the site. 

The site in Madera, CA, consisted of a tall fescue/rye mix. The Florida site, located in Keystone Heights, consisted of Bermuda grass. The Pennsylvania site, in Germansville, consisted of bluegrass. Thus, this study was performed on three major grass varieties in three distinctly different temperature zones in the U.S.

Plant Dicamba is hydrolyzed in wheat and Kentucky bluegrass plants to 5-hydroxy-2-methoxy-3,6-dichlorobenzoic acid and 3,6-dichlorosalicylic acid at yields of 90 and 5%, respectively. The remaining 5% was unreacted dicamba (Broadhurst et al., 1966). Dicamba was absorbed from treated soils, translocated in corn plants and then converted to...

In soil that has not had recent additions of plant residue or other organic material, microbial respiration proceeds at a low rate (13). Moreover, fungi apparently exist mostly as spores in a state of fungistasis. This microflora usually responds to the addition of plant residue by spore germination, increased respiration, and growth. These responses were induced by volatile components from alfalfa tops, corn leaves, wheat straw, bluegrass clippings, tea leaves, and tobacco leaves, even when the residue...
