Availability studies on magnesium in magnesic limestones, serpentine, olivine, and magnesium ammonium phosphate

Summary

The availability of magnesium in different magnesic limestones, Serpentine, Olivine and ammonium magnesium phosphate was studied in pot cultures using Irish Cobbler potatoes grown in a magnesiumdeficient soil as the plant indicator. In a similar manner the effect on tuber yields of the addition of calcium carbonate, magnesium sulfate, and extra potash to this soil has been determined. The results may be summarized as follows:

Potatoes were shown to be very responsive to applications of magnesium in the forms of magnesium sulfate and other carriers.

High levels of potash accentuate magnesium deficiency.

Tuber yields indicate a variation in the availability of MgO in the limestones used.

The magnesium in this particular Serpentine and Olivine is in a form available to potato plants, to approximately the same extent as in the poorer magnesic limestones.

Magnesium ammonium phosphate supplied magnesium in a very readily available form.
