Do farmers fertilize soybeans?
Soybean is an important crop in Minnesota and provides a significant return for many farms. The fertilizer needs of the crop are often neglected while attention is mostly directed at fertilizing other crops in the rotation….

Does soybeans need fertilizer?
Soybeans do not require high fertilizer application rates, yet, an accurate nutritional plan is necessary for increasing yields. Soybeans grains have a nitrogen content of 40%, therefore an adequate fertilization of nitrogen is a key factor in achieving high quality yields.
Can you plant soybeans without fertilizer?
Traditionally, soybean has been grown successfully without addition of N fertilizer. N management has been limited to rhizobia inoculation of fields new to soybean. An N “budget” developed from numerous research studies shows that soil and fixed N are generally sufficient to supply N needs at yields up to 60 bu/acre.
Which fertilizer is best for soybean crop?
Fertilizer Application
- Apply 20 kg N and 80 kg P2O5 and 40 kg K2O and 40 kg of S as gypsum (220 kg/ha) /ha as basal dressing.
- Soil application of 25 kg ZnSO4/ha under irrigated condition.
- Foliar spray of NAA 40 mg/l and Salicylic acid 100 mg/l once at pre-flowering and another at 15 days thereafter.
How much does it cost to fertilize an acre of soybeans?
Fertilizer costs increased more for corn than soybeans. As shown in Table 1, corn fertilizer costs increase $47 per acre (from $93 to $140 per acre) while soybean fertilizer costs increased $17 per acre (from $39 per acre to $56 per acre).
Can you plant soybeans every year?
Some years they grow soybeans exclusively. With soybean prices now, (continuous) soybeans is a no-brainer for some farmers. “If you stay on top of management, you can grow a heck of a soybean crop year after year,” he added. The Baileys’ soybean yields average 45 to 50 bushels per acre (bpa).
How much fertilizer do you put on soybeans?
Agronomists know that soybeans require 4.5-5 pounds of N per bushel produced. A 60-bushel crop will require about 300 pounds, and soybeans fix only enough nitrogen to produce about 50 or 60 bushels — and often, maybe only half of what the plant needs. So the rest of that nitrogen has to come from the soil.
How can I increase the yield of soybeans?
8 Tips To Higher Yields In Soybeans
- Scouting. Once a soybean crop is in the ground, weed control and pest and disease scouting is top priority.
- Fertility and pH Management.
- Weed Control.
- Irrigation.
- Harvesting.
- Variety Selection.
- Timing.
- Seed Treatments.
How do you make soybeans grow faster?
To increase your chances to attain ultra-high soybean yields, Davis provides the following top-seven tip list:
- Choose the right varieties.
- Consider soil fertility.
- Plant on time.
- Start with a clean field.
- Maximize light interception.
- Consider an inoculant and/or seed treatment.
- Scout often.
What are the growth stages of a soybean plant?
The soybean is a dicotyledonous plant, meaning that it has two embryonic leaves, or cotyledons. Soybean plants exhibits epigeal emergence, as the cotyledons emerge above the soil surface….Table 1: Vegetative stages.
Stage | Description |
---|---|
VE | Emergence: Cotyledons above the soil surface. |
What crop is most profitable per acre?
Bamboo is one of the most profitable crops to grow per acre. It can bring in lots of revenue, but the catch is it takes about three (3) years for the bamboo to get “established” once planted.
What is the break even price for soybeans?
The break-even on soybeans is around $10 per bushel. Most farmers who intend to plant next year can quote the markets by the hour. They know their market prices, their subsidy levels, their break-even costs.
When to fertilize soybeans?
You should fertilize based on a soil test taken every two years or more frequently. Phosphorus (P) and potassium (K) should be applied before soybeans are planted. In many states where soybean is in rotation with corn, P and K can be applied before the corn crop at amounts high enough for both the corn and soybeans.
Do soybeans need N fertilizer?
Traditionally, soybeans do not received much, if any, fertilizer . Soybeans are efficient in providing their own nitrogen through biological nitrogen fixation and typically, there has been enough residual phosphorus and potassium left behind by previous crops to provide essential nutrients.
How much fertilizer per acre for soybeans?
For a 60-bushel per acre soybean crop, this is 48 pounds per acre of actual P 2O 5 or 90 pounds per acre of monoammonium phosphate (MAP) or 100 pounds per acre of diammonium phosphate (DAP). Spring application of P fertilizers is recommended over fall application when soil pH levels exceed 7.4.
Could fertilizer boost soybean yields?
Large amounts of fertilizer did not boost soybean yields below that threshold, suggesting that the natural sources supplied enough nitrogen in those fields. However, the researchers found that nitrogen fertilizer consistently boosted yields above the 50-bushel threshold.
