If Ca were to become limiting then one would expect decrease of Ca in the soil solution=C2=A0which would force the weathering reaction of Ca containing minerals. =C2=A0 =C2=A0=C2=A0=C2=A0 That being said, the Noseworthy thesis if useful with re= spect to aspects which are less affected by subtle readjustments.
