Evaluation of Mehlich 3 as a Micronutrient Extractant on Irish Grassland Soils [PDF]
, 2002 The use of multinutrient extractants has been increasing in recent years, Mehlich 3 (M3) being one that has gained wide acceptance. The objective of this study was to see how M3 compared with methods currently used in Ireland for Cu, Zn, Mn and Fe extraction, and to investigate if it could be used to determine available Mo.
