- Intervention effect Corn responded to fertilizer Zn in 6 of the 7 years of the field study.
- Intervention effect One initial broadcast of 8 lb Zn/acre gave a response equal to 8 to 10 lb Zn/acre applied annually.
- Intervention effect Response to 4 lb Zn/acre in the fertilizer band at planting was statistically significant only after several annual applications were mixed with the soil.
- Association Extractable soil Zn with DTPA and with sodium acetate (NaOAc) was highly correlated in the corn soil.
- Method / resource The DTPA solution extracted three times more Zn than sodium acetate (NaOAc) from the soil.
- Observation Less than 10% of applied Zn was accounted for by subsequent soil extraction with DTPA.
- Association In the greenhouse, corn Zn content increased with root-zone temperature.
- Association In the greenhouse, corn Zn content increased with soil Zn additions.
- Association Response to band-placed Zn was greater at a lower temperature, where root growth was reduced.
- Observation Zinc deficiency in young corn plants can be expected when DTPA-extractable Zn is 0.6 ppm or less.
- Observation Zinc deficiency in young corn plants can be expected when the Zn concentration of young corn tissue is 16 ppm or less.
