| Abstract/Contents: | Mentions that high pressure water injection (i.e. the Toro HydroJect™) allows for subsurface applications of nitrogen fertilizers without disrupting the surface. Describes two studies conducted at Michigan State University whose objectives are the following: "to examine the interaction between deep nitrogen placement and aeration channels created by the HydroJect," and "to examine the differences in nitrogen uptake between surface and subsurface applications with regard to amount and duration of fertilizer nitrogen incorporated into turfgrass tissues." In the first study, evaluations of clipping yields, color ratings, quality ratings, soil moisture content, and root mass indicated that the 1 lb. rate of nitrogen per 1000 ft² provided more desirable results than the 0.5 lb. rate, and that injection treatments provided better results than surface applications. States that the second study "consists of two treatments: 1 lb. nitrogen per 1000ft² either injected of [or] surface applied"; the study will utilize coring to analyze different soil depths for nitrogen content. |
