How many soybean seeds should I plant?
Table 4. The "new" seeding rate guideline for optimum planting conditions are:
|15 inch||125,000 to 140,000 seeds per acre|
|30 inch||125,000 to 140,000 seeds per acre|
Should soybeans be soaked before planting?
Do not soak seed before planting and do not overwater immediately after planting; too moist seeds may crack and germinate poorly.
What month are soybeans planted?
Do soybeans need nitrogen fertilizer?
Soybean has a large nitrogen (N) requirement. Except for a small dose of N fertilizer applied as “starter” in some fields, most soybean crops rely almost exclusively on N supplied by soil organic matter mineralization and N fixation. ...
Do soybeans add nitrogen to soil?
Soybeans can add 30 to 50 pounds of nitrogen per acre to the soil. When grown in rotation with corn, grain sorghum or wheat, outside nitrogen fertilizer can be reduced.
How do you fertilize soybeans?
Apply dry fertilizer (P&K). Last season, after not using P or K for about a decade, he applied about $50 worth of P and K per acre, based on soil-test results. Soybean yields averaged 59 bushels per acre.
How do you know when soybeans are ready to harvest?
When field mature, seeds, pods and stem turn yellow. About four to nine days later, all pods on the plant have turned brown. At this point, seed moisture is about 33%. With good drying weather, the beans should be ready to harvest four to five days after this.
Why don t farmers put nitrogen fertilizer on soybeans?
Soybean is able to fix most of the N it needs through its symbiotic relationship with rhizobia bacteria. It also takes up residual and mineralized N from the soil. Traditionally, soybean has been grown successfully without addition of N fertilizer.
Do soybeans improve soil?
Soybeans leave nitrogen-rich residue in the soil, which leads to vigorous growth of decomposer bacteria and fungi microbes. ... It may be possible to sustain or increase organic matter by introducing other grains and legumes as well as cover crops, such as rye or oats, into corn and soybean crop rotations, Hall says.
What deficiencies can soy actually cause?
Thousands of studies link soy to malnutrition, digestive distress, immune system breakdown, thyroid dysfunction, cognitive decline, reproductive disorders and infertility -- even cancer and heart disease.
Does fertilizing soybeans pay?
Traditionally, soybeans do not received much, if any, fertilizer. With more soybean acres and less fertilizer applications, many fields have seen nutrient deficiencies. ... In many fields soil test values have now slipped to the point where precious soybean yield is being lost.

For a 60 bushel per acre soybean crop, this is 48 pounds per acre of actual P2O5 or about 90 pounds per acre of monoammonium phosphate (MAP) or about 100pounds per acre of diammonium phosphate (DAP).
How much potash do Soybeans need?

Do soybeans need potassium?
Soybeans require potash and plenty of it and remove more than corn. A 200-bushel corn crop will remove 50 lbs. of potassium per acre, while an equivalent 70-bushel bean crop will remove 84 lbs.
Can you put to much potash on soybeans?
Too Much Potassium Can Sometimes Ding Corn, Soybean Yields.
Do Soybeans need more P or K?
Q: What are the optimum soil test P and K levels for soybeans? A: University researchers have correlated soil test P and K levels with soybean yields. As soil test P and K levels increase, soybean yields increase up to optimum levels where P and K are no longer yield limiting.
