A study of the inclined point quadrat method of botanical analysis of pasture mixtures
1942
Arny, A.C. | Schmid, A.R.
Data have been presented showing that percentages of certain species in pasture mixtures determined from readings from the inclined point quadrat apparatus were over- or underemphasized when compared with determinations from dry weights. A method of correcting for the overemphasis of Kentucky bluegrass alone, Kentucky bluegrass and crested wheatgrass together, and for the underemphasis of alfalfa from the readings from the point quadrat apparatus in the mixtures studied in 1941 was derived and used for that purpose. With a few exceptions, the percentages of these species as determined from the corrected readings from the point quadrat apparatus approached rather closely the percentages determined for them from dry weights.
