Title

Other claims from this paper (14)
- Observation Symptoms of magnesium deficiency and take-all disease occurred in wheat in 1967 on the Classical cereal site at Woburn
- Intervention effect Magnesium fertilizers cured magnesium deficiency symptoms in wheat in 1968 and 1969
- Intervention effect Magnesium fertilizers increased wheat yields in 1968 and 1969
- Intervention effect Magnesium fertilizers had no effect on take-all in wheat
- Association Leaves of take-all-attacked wheat contained less nitrogen and potassium than leaves of unattacked plants
- Association Leaves of take-all-attacked wheat did not contain less magnesium than leaves of unattacked plants
- Intervention effect Magnesium fertilizer did not increase spring barley yields in 1969
- Intervention effect Magnesium fertilizer did not affect take-all in spring barley in 1969
- Intervention effect Magnesium fertilizer improved clover establishment, especially on soil with the least magnesium
- Observation Exchangeable soil magnesium declined tenfold since 1888
- Intervention effect Magnesium losses were highest from soil given ammonium sulphate
- Association Magnesium losses were higher from the site where wheat was long grown than from the site where barley was
- Association Differences in soil magnesium did not explain yield differences in potatoes between experimental blocks
- Association Differences in soil magnesium did not explain yield differences in leys between experimental blocks
