Verbatim
e1“Maize, cv. Ganga-5, was grown as the test crop”
e3“In soils where this ratio was between 0·026 and 0·05, application of potassium fertilizer was beneficial only up to the intermediate amount of 11 mg K/kg soil. Beyond this amount of application, addition of magnesium was necessary to increase yields”

Other claims from this paper (6)
- Intervention effect Potassium fertilizer significantly increased dry-matter yield of maize in soils with an exchangeable cation ratio below 0.025
- Intervention effect Potassium fertilizer was beneficial for maize yields only up to 11 mg K/kg soil in soils with a cation ratio of 0.026-0.05
- Intervention effect Potassium fertilizer reduced maize yields in soils with a cation ratio above 0.05
- Association An optimum ratio of exchangeable calcium, magnesium and potassium is more important for maize than their absolute amount
- Intervention effect Magnesium application to high-potassium soils improved the cation equivalent ratio within maize plants
- Intervention effect Magnesium application to high-potassium soils improved dry-matter yield of maize
