Intervention effect Phosphorus increased rye yield without lime, with greater response when lime was present.
Intervention effect Phosphorus increased rye percent P without lime, with greater response under liming.
Intervention effect Lime plus phosphorus produced larger millet yield differences than rye.
Intervention effect Lime plus phosphorus produced larger millet percent P differences than rye.
Intervention effect With added phosphorus, liming increased millet yield until pH about 5 to 6, then further lime decreased it.
Intervention effect Further lime beyond pH about 5 to 6 decreased millet yield.
Intervention effect Initial lime applications increased millet percent P.
Intervention effect Plants on limed soil were healthier and had better developed roots.
Mechanism The authors attributed higher shoot percent P to healthier, better developed roots on limed soil.
