Corn-Requires firm seed to soil contact for proper germination.
Sends narrow spiral shoot.
|
Firms soil tightly
around seed for necessary seed to soil contact. |
Not designed
for corn. |
Not designed
for corn. |
| Small Grain-Small seed requires
tight seed to soil contact without air pockets. Narrow spike emerges
from shallow depth. |
Not designed for small grains. |
Ideally suited for all cereal
grains. |
Precision depth control
ensures excellent stands if 10" minimum row spacing is acceptable. |
| Soybeans-Germination less dependent
on firmed soil surface. Must push wide fragile cotyledon to soil surface. |
Crusting caused by tightly
firmed soil over the row may compromise emergence. |
Poor depth control may require
overseeding. Packed soil over row may cause crusting. |
Uniform depth and seed firming
provide excellent germimation. Unpacked soil over firmed seed prevents
crusting and emergence problems. |
