Other claims from this paper (12)

Observation Corn responded optimally to P fertilization at 44 kg P/ha.
Intervention effect High P supply beyond the optimum rate produced severe Zn deficiency symptoms in corn without added Zn.
Intervention effect High P supply decreased grain and stover yields of corn.
Intervention effect High P supply decreased Zn concentration in corn shoots.
Intervention effect Increased Zn supply alleviated Zn deficiency symptoms in corn.
Intervention effect Increased Zn supply significantly increased Zn concentration and uptake in corn.

Method / resource P/Zn values above 7.5 in soil, 245 in grain, 130 in stover and 150 in leaves indicated severe Zn deficiency in corn.
Method / resource P/Zn values of 4 to 7.5 in soil, 150 to 245 in grain, 90 to 130 in stover and 100 to 150 in leaves indicated moderate Zn deficiency or response in corn.
