e0“On average, 100 kg/ha magnesium as kieserite increased the mean sugar yield of 7·55 t/ha by 0·17 t/ha whereas 200 kg/ha magnesium as calcined magnesite increased it by only 0·08 t/ha; on fields with less than 15 ppm exchangeable magnesium the magnesium fertilizers increased sugar yield by 0·34 and 0·10 t/ha respectively and there was no response to either fertilizer when the soil contained more than 25 ppm of exchangeable magnesium.”

- Observation Fertilizers were almost equally effective on slightly acid soils.
- Observation At pH above 7.6, little magnesium was taken up from calcined magnesite.
- Intervention effect Grinding calcined magnesite increased magnesium availability.
