Set-Up Soybeans for Success in 2022

Hardin County – For soybean, pre-planting decisions are extremely important to set-up the crop for success. Soybean Extension Specialists from across the U.S. have been working together on the Science for Success initiative (funded by United Soybean Board) focused on leveraging local expertise to provide national soybean best management practices. Recently, we’ve focused on soybean planting date, row spacing, and seeding rate.

Soybean planting date has a large effect on yield. In Ohio, yield reduction as a result of late planting ranges from 0.25 to 1.0 bushel per acre per day. In our small plot research in Clark County, Ohio, soybean yield reduction in 2013 and 2014 was approximately 0.6 bushel per acre per day for each day planted after early to mid-May. Although early planting is important to maximize soybean yield, deciding on when to plant should be based on field suitability and soil temperatures at the time of, and following, planting as well as frost forecast.

Soybean can germinate and emerge when soil temperatures are at or just below 50°F. At soil temperatures between 50-60°F, soybean plants typically take about 15 to 20 days to emerge following planting. Planting into a wet seedbed or following too much tillage can result in compaction and soil crusting which could reduce stand establishment. At the same time, planting into extremely dry soil can also be detrimental to stand establishment due to insufficient soil moisture for germination and/or emergence.

For Ohio, in general, we recommend soybean be planted any time after April 15 in the southern portion of the state and any time after the last few days of April in the northern portion of the state IF soil conditions are satisfactory.

In Ohio, soybean is generally grown in narrow rows (7.5 to 15-inch row width). Soybean plants grown in narrow rows generally produce more grain than soybean grown in wide rows (30-inch row width) because they capture more sunlight energy, which drives photosynthesis. Across the U.S., soybean grown in less than or equal to 15 inch row width has a yield advantage of 1 to 4 bushels per acre compared to greater than 15 inch row width. However, these yield advantages are typically greater with later planting dates, earlier maturing varieties, and high temperatures, all of which reduce the time from VE (emergence) to R3 (initial pod set).

Soybean plants are incredibly flexible at adjusting to a wide range of plant populations. Soybean plants in low populations will produce more branches, more pods, and more seeds per plant. Soybean at higher populations will grow taller, produce fewer branches, pods, and seeds per plant. Because of this flexibility, soybean can often produce similar seed numbers per acre and similar yields over a wide range of plant populations.

In Ohio, for a crop planted in May, a final plant population of 100,000 to 120,000 plants per acre is generally adequate for maximum yield. Final population is a function of seeding rate, quality of the planting operation, and seed germination percentage and depends on such things as soil moisture conditions, seed-soil contact, disease pressure, fungicide seed treatments, etc.

Ensuring maximum yield requires farmers to plant at rates higher than the minimum required plant population. As a general rule, seed about 25% higher than the target plant population. For example, for a target plant population of 100,000 to 120,000 plants/acre, you may want to seed 125,000 to 150,000 seeds per acre.

Early Season Manure Application

Hardin County – Last fall was not favorable for manure application to farm fields. Thus, many producers are interested in spring application with an eye on capturing the nitrogen contained in the manure to reduce the need for purchased nitrogen.

In-crop applications of manure make the best use of the manure’s nitrogen content for crop uptake. At the early vegetative stages, the timing is close to the crop’s maximum nutrient uptake period. In corn, placement of the manure below the surface preserves a higher percentage of nitrogen through reductions in volatilization losses. When used as a substitute for purchased nitrogen fertilizer, the economic case for manure used in this way is very attractive and provides an incentive to haul manure greater distances.

Preplant applications of manure can work almost as well as in-crop manure application. The challenge is to get the manure incorporated, to capture the nitrogen, without delaying spring planting due to the field being too wet or the field made too rough for planting. An acre-inch of water is 27,154 gallons. Applying 7,000 gallons in the spring is like adding a quarter inch of moisture if spread evenly. If the manure is applied in strips, then the field could take longer to dry.

The Ohio State University conducted five years of research on preemergent manure application. The manure application was made after corn had been planted the previous day. Yield results were significantly higher than commercial fertilizer applied at the same time. Based on fall stalk-nitrate tests, the manure appears to stay with the growing corn crop much longer than the commercial fertilizer. This should give farmers confidence that spring applied manure can provide the nitrogen needed by the corn crop over the entire growing season.

The key is to apply the needed nitrogen and get the manure below the soil surface. Most swine finishing buildings contain from 30 to 40 pounds of ammonium nitrogen per 1,000 gallons. But there are exceptions to this guide so be sure to rely on previous manure tests. Dairy manure would be much lower at eight to 15 pounds per 1,000 gallons. Research also shows that some agitation of the manure source prior to application will produce more consistency of the nitrogen, phosphorus, and potash over the course of emptying the manure storage.

Another key is to do your best to avoid soil compaction. Manure tankers are heavy and soil compaction can be seen throughout the growing season and on combine monitors during the harvest season. This would be a good reason to favor using a drag hose for spring manure application if possible.

If a producer gets the manure application made, then the producer could utilize a Pre-Side-dress Nitrate Test (PSNT) to determine if additional side-dress nitrogen is needed or utilize tissue testing and Y-drop nozzles to determine if additional nitrogen is warranted.

The application of manure to corn focuses on the 4R’s of nutrient stewardship. These are the right product, the right rate, right placement, and right timing to maximize crop yield and minimize environmental impacts.

As the granddaughter of a Hardin County farmer, Jami Dellifield knew that agriculture didn’t easily make room for mental health care. “We pull ourselves up by the bootstraps and nobody talks about hard things – it’s a pride issue,” said Dellifield, a family and consumer science educator with Hardin County OSU Extension. When she started in her role, she realized that the office needed to do much more to help farmers seek care for the mental stress of their 24-hour-a-day jobs. So, she set to work. Dellifield was awarded the first Yvonne Lesicko Perseverance Prize, established to honor Lesicko’s work at Ohio Farm Bureau that helped create the "Got Your Back" coalition to combat farm stress.
