The impacts of simple fertilizer tr

The impacts of simple fertilizer treatments on many of
the chemical and microbial properties of the soil were
not significantly different from those of the control.
They also were not as beneficial as the balanced treat
ments in terms of grain yield returns. Overall responses
were positive in balanced fertilizer treatments, suggesting
that judicious use of inorganic fertilizers may, in the
long-term, maintain soil quality and productive capacity.
It might, however, be necessary to consider supplemental
liming to counteract the resulting acidifying effect and
decline in Ca2+ and Mg2+ levels.
