4.11 Side Banding with Anhydrous

Ammonia

Extreme caution must be exercised when side banding with anhydrous ammonia

(NH

). If the separation distance between the seed and the NH

is not sufcient,

the germinating seedling can be damaged.

Several factors affect how far from the point of injection in the soil NH

will

move:

• NH

will move farther in dry soils than wet soils. Hilltops tend to have low-

er soil moisture content and are therefore more susceptible to NH

travel.

• NH

will move farther in light textured soils (e.g., sandy soils) than in heavi-

er textured soils (e.g., clay soils).

• NH

will move farther in soils with low organic matter.

• If the soil is lumpy or not closing behind the knives, NH

can move more

quickly through the cracks or between the lumps of soil.

• Higher concentrations of NH

will cause the product to move farther in the

soil.

Other Factors to Consider:

• Some crops are more sensitive to NH

burn. Generally, oilseed and pulse

crops are more sensitive than cereal crops.

• Turning, while seeding, can vary the relative position of the seed and fertiliz-

er knives. This results in a larger separation of seed and NH

• When the fertilizer knife trips, it raises the injection point of the NH

and

may affect the separation of the seed and NH

WARNING! Use extreme caution when applying anhy-

drous ammonia fertilizer. Inhalation, skin and/or eye con-

tact, or skin penetration can cause serious health problems.

Seek medical attention immediately if coming into contact

with anhydrous ammonia.

4.12 Drop Tube Extension with NH

The delivery drop tube should extend 0.5 in (13 mm) past the stainless steel

clips. This usually prevents mud from freezing to the fertilizer knife.

IMPORTANT! Seed Hawk

assumes no responsibility for any seedling damage

caused by anhydrous ammonia burn. The operator is responsible for checking

and setting the seeder in all eld conditions.
