murflow - 8/7/2009 11:10 Heavy clay soils. We don't have any problems of high pH that I know of. My soil tests on these farms have a lower Manganese reading than my other farms. Thanks for explaining the relation between Manganese and nitrogen fixation. how do you know the paleness isn't moly deficiency? (which severely inhibits N-fixation in nodules) or even sulfur deficiency? |
