e3“The results of the greenhouse study showed in the absence of leaching that the application of two Zn sources significantly increased maize (Zea mays L.) dry matter yield compared with the control treatment although the increase in the Zn dosage did not increase dry matter further”

Other claims from this paper (8)
- Observation Zn in the most labile soil fraction was detected only when Zn-CH fertilizer was applied.
- Observation A large portion of Zn applied to soil occurred in the amorphous Fe oxide bound fraction in all fertilization treatments.
- Intervention effect Addition of Zn-CH greatly increased the mobility of Zn through the column compared with the control and the Zn-AA source.
- Observation In the column study, 49% of Zn applied as Zn-CH was leached.
- Intervention effect Two Zn sources significantly increased maize dry matter yield compared with the control treatment in the greenhouse, in the absence of leaching.
- Intervention effect Fertilizer treatments significantly increased Zn concentration in maize plants, except the lowest dosage of Zn-AA.
- Intervention effect Zn-CH was more effective than Zn-AA for maize.
- Association Plant Zn uptake in the greenhouse was correlated with DTPA extractable Zn in the incubation experiment.
