5 Ways to Ensure Better Soybean Health

United Soybean Board

Although each crop has specific needs to be able to achieve their maximum economic yield, soybeans have earned themselves a reputation for being a lower-maintenance crop. Growers might be surprised to see that with a little extra effort, they can have more impact on their soybean yields by producing stronger and healthier plants. With this careful attention, yield results may prove surprisingly better come harvest.

Soybean growers will have a more successful season if they stay aware of the following soybean sensitivities:

1. Timing and Planting Environment

Soybeans, like corn, benefit from an earlier planting time. With longer exposure time, the crop receives more sunlight and water. In addition to finding the timing sweet spot for planting, growers should be aware of ideal soil temperature when planting soybeans. The benefits of an earlier planting date can be diminished if the soil is too cold to successfully germinate the seeds and encourage a strong emergence. Ideal soil temperature for planting beans is around 55° to 60° Fahrenheit.

2. Planting Depth

During the planting process, exact location of the soybean seed is vital to ensure uniform emergence. Soybeans are likely to prosper when planted about 1.25 to 1.5 inches into the soil. At this depth, the seeds will have access to the moisture they require to develop. With all seeds planted at or near the same depth and with access to appropriate moisture, growers should see better consistency across their field.

3. Seed Treatments

When it comes to soybeans, growers should understand what disease and pest pressures they need to be aware of for their respective fields. Their local ag retailer can help them develop a strategic plan to achieve their soybean yield goals. With current options in customized seed treatments, retailers can help their customer with a specialized seed treatment that best helps them get their crop off to a good start, but is also cost effective since it includes the active ingredients they need and not a lot of products they do not need.

4. pH Sensitivity

Soybean plants grow better in soils with a balanced pH level. According to Fred Below, Ph.D., plant scientist at the University of Illinois, the ideal range is between 6.0 and 6.8. The root system of the soybean plant leaves them vulnerable to soils that are more acidic or soils that tend to be heavily alkaline. The soybean plant’s single taproot only allows it to extract nutrients from one concentrated area. Acidity from the plant can be helpful to its growth initially, but if it is washed away by rain, the soil can become alkaline heavy. This makes nutrients unavailable to the plant. On the other hand, soil that is more acidic will shut down microbes in the soil. Maintaining a healthy, balanced pH level is an important to ensure the soybean plants are able to access an optimum level of nutrients at the time they need them to produce the best possible yields.

5. Soil Fertility

There are several nutrients that are critical to developing a healthy and high yielding soybean plant. Phosphorus and potassium are two key players in soybean health. Potassium helps with water management and disease prevention while phosphorus is used during growth and reproduction to store and help transfer energy produced by photosynthesis. It also helps enhance shoot and root growth and promote early maturity.

Micronutrients are also important to proper growth of soybeans. For example, soybeans need access to the appropriate amounts of soluble iron to develop into healthy plants. Iron is critical to the development of chlorophyll within the plant. Iron Deficiency Chlorosis (IDC) is a common soil issue in some areas of the country. IDC tends to occur in soil with high pH levels, which can prevent plant roots from reducing iron to a soluble state that can be used by the plant.

Celebrate National Ag Day on March 21

“Growing up in rural South Dakota, surrounded by farms and ranches as far as the eye could see, I never gave the food supply chain a second thought. It was intertwined in everything I did,” writes Mark Biedenfeld, vice president, CHS Aligned Solutions on the Ag Day blog. He goes on to emphasize the important role those in agriculture play in helping our broader communities understand where their food comes from.

Biedenfeld joins others in contributing to the blog in a nod to National Ag Day, coming up this Tuesday, March 21. The celebration is now a tradition across the U.S., created to recognize and celebrate the abundance provided by agriculture. Agriculture provides almost everything we eat, use and eat on a daily basis, and is increasingly contributing to fuel and other bio-products. (more…)

5 Ways to Ensure the Best Stand

LivingLandscapeArchitecture

Uniform stand establishment is a critical component in achieving maximum yield potential. With unexpected weather and other uncontrollable factors often impacting the crop’s stand, it is even more important to be proactive in the areas that can be controlled. Fortunately, there are steps to help get your crop off to a strong start and encourage a strong and healthy stand.

1. Seed Selection

Each season it all starts with selecting your seed. There are multiple considerations growers need to be aware of when selecting the appropriate seed, including the geography, any unique field conditions, potential impact from weeds, disease and pests, maturity timing, etc. These considerations need to be evaluated in cooperation with your farm management practices to ensure the best results. Read more on considerations for seed selection, for soybeans and for corn. (more…)

Preparing for a Successful Planting Season

As the weather begins to creep into warmer temperatures and the sun lingers in the sky longer in the evening, thoughts of spring come to mind.

With the 2017 planting season quickly approaching for many and even if still several weeks away for cooler geographies, it is a key time to make sure that plans are underway to help get the crop off to a strong start. Having a set schedule and list leading up to your key planting dates will provide extra time as necessary to be devoted to any unexpected issues as they arise. (more…)

The Future of Drones in Agriculture

Could drones be the future of agriculture – and a game-changer?

According to a late 2016 article in Successful Farming, drones also known as unmanned aerial vehicles (UAVs) were first received with hesitation in the agriculture industry. Although the new technology was known to provide growers with a way to see potential problems that wouldn’t otherwise be known from ground level, the new technology was taken with initial apprehension due to the lack of regulations, in addition to the sometimes challenging process of applying for a Section 333 exemption through the FAA.

Slowly but surely, the agriculture industry is realizing the benefits and discovering different strategies on how drones can benefit and move their crop production plans forward. (more…)

Fighting Hunger in Rural America with CHS Harvest for Hunger campaign

Harvest for Hunger 2017 children help fight hunger in the CHS Harvest for Hunger drive

It’s once again time for farmers, ranchers and cooperatives to come together in a powerful campaign to knock out hunger. The CHS Harvest for Hunger food and fund drive begins March 1 and will continue through March 20 at your nearest CHS location.

Using Soil Sampling Results To Improve Your Next Crop

We recently discussed the importance of soil sampling and what growers learn from testing samples from their field. Now we want to look more at what the results can tell the grower and how it can help them improve their next crop.

As growers receive information regarding organic matter, soil pH, Cation Exchange Capacity (CEC), Nitrate-N and extractable macro and micro nutrients from their soil sample results, they will be able to make more informed fertility decisions, and address potential issues in advance or during the early stages of the plant’s growth cycle.

The results also provide a holistic view of the health of the soil, and can help provide growers with an indication of success for their fertility philosophy by determining if the following are needed:

  • Building nutrient levels
  • Maintaining nutrient levels
  • Reducing of specific mineral levels
