Several soils were cropped with four concecutive crops of oats (Avena sativa, 'Garry') in the greenhouse. Changes in exchangeable Mg levels were used to indicate uptake from that source. The remainder of the uptake was attributed to the nonexchangeable source. Total uptake by the four crop did not appear to be related to total Mg level in the soil, percent clay in the soil, or exchangeable Mg level. Mg availability did appear to be related to the mineralogy of the medium clay fraction. |
