Ground magnesium limestone contains high amounts of Ca
and Mg and so does ground basalt and organic fertilizer
(Table I). Additionally, ground basalt and organic fertilizer
contain significant amounts of K and P. Hence, application of
these amendments to the soil should boost its chemical
fertility somewhat. However, the changes in solutions Ca,
Mg and K due to the application of these amendments were
erratic for both cycles 1 and 2, and therefore, the results are
inconclusive. This is also true for the changes in exchangeable
Ca, Mg and K. The exact reason for this phenomenon is
unknown at this stage. It may be that the ground basalt
applied into the soil was not completely dissolved within the
experimental period. A past study indicated that it took more
