Updated on April 20, 2026
Soil pH of 6 – 6.8 is ideal. Banding fertilizers and foliar feeding are common application methods but should be considered only when conventional methods are not satisfying. Soybeans grains have a nitrogen content of 40%, therefore an adequate fertilization of nitrogen is a key factor in achieving high quality yields.
How can I increase the yield of soybeans?
- Spend time on variety selection. …
- Know your fields and consider your cropping system. …
- Maintain your fertility foundation. …
- Plant early and consider prescription planting and variable variety placement. …
- Use of seed treatments and inoculants. …
- Use a preemergence herbicide.
When should you apply nitrogen to soybeans?
Apply N from full bloom (R2) through beginning pod (R3) or full pod (R4). Apply 20 to 50 pounds of N either as liquid or dry urea either dribbled on the soil surface, or broadcast. Apply a foliar feed with some N to make sure the plant’s metabolic machinery is working at optimal capacity.
What is a good starter fertilizer for soybeans?
Phosphorus promotes early root growth and potassium has been shown to increase soybean root nodulation and biological nitrogen fixation. Small quantities of nitrogen – 10 to 20 pounds of actual N per acre – may promote early growth, but have rarely increased soybean yields in university research trials.Do soybeans need nitrogen fertilizer?
The soybean crop has a high requirement for nitrogen; the crop takes up nearly 5 pounds of nitrogen per bushel, and about 75 percent of that is removed in the harvested crop. … Nitrogen fixation takes a considerable amount of energy in the form of sugars produced by photosynthesis in the crop.
Do soybeans need sulfur?
Soybeans have more complex nutrient needs than previously thought and require nutrients throughout the growing season. As a secondary nutrient, sulfur (S) plays a critical role in the growth and development of high-yielding soybeans: Necessary for optimum growth during the vegetative and reproductive stages.
Do soybeans need potash?
Answer: Soybeans are big users of potash. A 60 bu/A soybean crop removes 87 lbs K20 which is equal to 145 lbs potash (0-0-60) per acre. A 200 bu/A corn crop removes 58 lbs K20 which is equal to 97 lbs of potash. So yes, soybeans need potash as well as does corn.
What do you need to grow soybeans?
Plant soybeans in full sun; soybeans will tolerate partial shade but the yield will be reduced. Soybeans grow best in loose, well-drained soil rich in organic matter. Soybeans prefer a soil pH of 6.0 to 6.8. Soybeans are tolerant of poor soil.Does starter fertilizer pay on soybeans?
Soybean is a crop that can remove significant amounts of nutrients per bushel of grain harvested. Because of this, soybeans can respond to starter fertilizer applications on low-testing soils, particularly phosphorus. In many cases, corn shows a greater response to starter fertilizer than soybean.
How long does it take soybeans to come up?It commonly takes a soybean seed about two days to germinate. The plant doesn’t emerge from the ground until about one week after planting. Each plant can produce up to 80 pods and about 160-200 seeds per plant.
Article first time published onShould I fertilize my soybeans?
The fertilizer needs of the crop are often neglected while attention is mostly directed at fertilizing other crops in the rotation. Soybean crop yields will decrease when it lacks essential nutrients. Therefore, it’s important to develop a profitable fertilizer program to maximize crop yields.
Will liquid fertilizer work on soybeans?
Soybeans have a critical need for phosphorus and potassium from germination through reproductive stages, where maximum yield potential is determined. … ALPINE liquid fertilizers can also be tank-mixed with most glyphosates and fungicides to save soybean growers time and money!
Why don t farmers put nitrogen fertilizer on soybeans?
Soybean crop residue contains considerably more nitrogen than corn residue, which speeds up the process of residue decomposition and ties up less N in the subsequent corn crop. Thus, less N needs to be applied to corn following soybean.
What is the best row width for soybeans?
Row spacing is a management decision that often comes up as a priority for achieving high-yielding soybean. Research across the Midwest over several years has consistently shown that soybean planted in narrow rows (<30 inches) has a yield advantage compared to wide rows (≥ 30 inches).
Do soybeans add nitrogen back into the soil?
When legumes die, their residue is easily broken down by microorganisms that release nitrogen back into the soil. … Soybeans are one of the most common legume crops grown in Missouri. Soybeans can add 30 to 50 pounds of nitrogen per acre to the soil.
How do I get more soybean pods?
Plant early and use a longer maturity group to get more nodes which increases number of pods. Fertilize properly. Fertilization improves pod set in the middle and top regions of the plant and increases seed weight in the bottom and middle regions. Keep plants healthy.
What fertilizer is high in potash?
Fertilizers that are high in potassium include: burned cucumber skins, sulfate of potash magnesia, Illite clay, kelp, wood ash, greensand, granite dust, sawdust, soybean meal, alfalfa, and bat guano.
What is a good phosphorus and potassium fertilizer?
Choose a blend that has at least as much phosphorus and potassium (the second two numbers) as nitrogen (the first number), such as 10-10-10. If your soil is moderately to severely deficient in phosphorus and potassium, opt for blends that are higher in the last two numbers, such as 5-20-20 or higher.
How many pounds of potash can you get per acre?
125 pounds of nitrogen, 50 pounds of phosphate, and 265 pounds of potash per acre.
Do soybeans need zinc?
Zinc is critical in the early growth stages of soybeans, and is a necessary nutrient to produce chlorophyll and carbohydrates. Plants deficient in zinc will suffer from shortened internodes and stunted leaf growth. Boron aids soybeans in developing proteins and assists in seed setting.
How much potassium do Soybeans need?
Potassium is a vital part of a robust nutrient plan More specifically, it helps regulate the opening and closing of the stomata, which facilitate the exchange of water and gas vapor in and out of the plant. In soybeans, K needs are especially high: Around 1.4 lbs potash (K2O) is removed per bushel.
How do you apply sulfur to corn?
It’s a good practice to add sulfur to your starter fertilizer program as ammonium thiosulfate: 12-0-0-26S. Rates of 3 to 5 gallons per acre placed next to or above the germinating seed are ideal for a starter practice. A second option would be to broadcast ammonium sulfate, 21-0-0-24S, at or after planting.
How do you grow soybeans in Michigan?
- Plant in the early afternoon to allow soils to warm up.
- Avoid planting when rain is imminent within 24 hours after planting. …
- Plant later-maturing varieties as they are less susceptible to imbibitional chilling injury than early-maturing varieties.
Can you broadcast soybeans?
Broadcast-seeding soybeans can create multiple challenges for farmers, experts contend, and it’s not recommended for every part of the country and soil type. There are no rows or tram lines, so some soybeans are run over while spraying. Depending on timing and boom width, this can equate up to a 2.5% yield loss.
What type of soil is best for growing soybeans?
The best soybean yields occur on well-drained, but not sandy, soils having a pH of 6.5 or above. The critical stage for soybean yield is in August and droughty soils that typically dry out in August will have disappointing yields.
What grows well next to soybeans?
- Corn.
- Squash.
- Potatoes.
- Cucumbers.
- Strawberry.
- Celery.
- Summer Savory.
How long do soybean plants live?
Under these conditions, soybean seeds will remain viable for three to four years.
What happens when you plant soybeans to deep?
However planting soybeans too deep can result in reduced stand and seedling vigor. This occurs because soybeans need to expend their energy reserves trying to get the seed out of the soil which can delay emergence.
Do Soybeans need a lot of water?
Soybeans require approximately 15 inches to over 25 inches of water per year depending on planting date, maturity group, location, and weather conditions. … Significant reductions in yield can occur if soybean does not receive enough water to meet ET demands during this critical water use period.
Do soybeans need lime?
Optimum soybean yields cannot be achieved without adequate lime. Soybeans are more sensitive to high levels of soil acidity than most other field crops. The optimum pH for soybeans on sandy and clay-textured soils ranges from 5.8 to 6.2.
What is the best planting depth for soybeans?
Soybean should be planted at 1 to 1.5 inches deep, but no deeper than 2 inches. Ultimately, soybean planting depth should be field specific and based more on soil conditions at the time of planting.
