Please test your soil!
Under favorable conditions, apply 1 - 1.25 lbs of Nitrogen/day of planned growth should be available for ultimate growth, with little risk for nitrate poisoning.
For example, for a planned 40 day harvest, 40 - 45 lbs of Nitrogen should be available throughout the growing season.
Potassium levels should be maintained similar to that of cornIf soil pH is greater than 7.2, an application of Iron may be necessary to prevent Iron Chlorosis.
Seeding
Soil Temperature of 60 degrees F and climbing
Average Seeds Per Pound 14,000 - 16,000
Planting Depth should be 1" to 1 W', depending on soil moisture Follow recommended seeding rates for your area:
Higher Moisture areas: 50 – 60 pounds per acre
High Plains (lower moisture): 20 – 25 pounds per acre
Can be no-tilled into the stubble of winter and spring crops
Do not plant in soil with pH greater than 7.5 as Iron Chlorosis
Avoiding poisoning
To avoid nitrate and prussic acid poisoning:
Do not harvest drought stricken plants within four days following a heavy rain.
Do not apply Nitrogen prior to expected drought periods.
If in doubt, cut at a higher stubble height as nitrates tend to accumulate in the lower stalk If high Prussic Acid are found, wait one month prior to feeding.
Unlike excessive nitrates, prussic acid will escape from the plant over time.
