| Abstract/Contents: | Presents a study conducted to compare different methods of evaluating turfgrass quality, including clipping yield as fresh and dry matter, the chlorophyll content, and "a commercially available optical sensing system." Details methods and materials used in the study, stating that "the trial was carried out at the turfgrass research field of the BASF Agricultural Center [in] Limburgerhof in the upper Rhine valley in southwest Germany in 2005 and 2006 on a mature polystand of Lolium perenne (Lp), Festuca rubra (Fr) and Poa pratensis (Pp)...During the vegetation period from April to September the following parameters were evaluated weekly: turf quality"; "clippings fresh biomass"; "clippings dry biomass"; "chlorophyll content of fresh leaves measured with a spectrophotometer after DMSO extraction"; "near infrared reflectance (NIR)." Also states that "in addition to this trial [researchers] comapred sensor ratings with ratings of turfgrass quality also on other trials of this research field with and without artificial wear to increase the data pool and broaden the scope of the study." Reports that "the closest correlation between the effects of the diferent fertilizer treatments can be observed by the ratings of turfgrass quality. The measurement of clipping yield, dry matter content and clorophyll content is quite labor consuming, but not to superior to rating." Concludes that researchers "found quite good correlations between the aspect and both the chlorophyll content and the clipping yields. There was only a weak correlation between ratings of turf quality and the sensor values of NDVI. The variation of the latter is not accpetable for research purposes on [the] research field." |
