more profitable. Positive trends that have been established and proven were present again in 2023, such as early planting date, fall nitrogen, ATS, early season nutrition and season-long nutrition management with crop protection applications. A couple of highlights on corn this year were early season zinc (Zn) nutrition, specifically our new planter box option, BRANDT EnzUp SeedFlow Zn and the combination of BRANDT Smart K B with a fungicide application. On soybean, seed treatments continue to provide early plant health and vigor; also, season-long foliar management with nutrition and crop protection into the early reproductive stages yielded a return on investment.

We experienced some weather extremes, which have become more frequent. Periods of heavy rainfall proceeded a lengthy period of almost no rain. The research farm mostly missed the extreme wind event that hit hard throughout parts of central Illinois. These extremes provide learning experiences as we test ways to best manage through challenging climate scenarios.

Corn and Soybean Planting Date Location: BRANDT Research Farm – Pleasant Plains, IL 2023 Planting Date Trials: ■

Corn yields were maximized in 2023 when planted on March 30, yielding 49.8 bu/ac more than corn planted on May 11 when ATS was applied.

■

The application of ammonium thiosulfate (ATS) at planting was most responsive at the March 30 planting date, increasing yield by 40.1 bu/ac. ATS has consistently increased corn yields at the research farm when planted early due to lack of sulfur mineralization in cooler soils. Additionally, ATS lowers the pH near the band of application making other elements like zinc more plant available.

■

Minimal yield differences were observed between soybean planting dates in 2023 with the highest yield produced by the April 26 planted crop. The air temperature dropped below 30°F at the research farm on April 7 and April 24 including light frost damage to the cotyledons of the March 30 planted soybean.

2023 Corn Planting Date Study: Corn planted every two weeks from March 30 to May 11.

Pleasant Plains Research Farm Historical Planting Data: ■

Historical planting date data from the research farm shows that corn and soybean both follow a similar yield decline as planting date is delayed.

■

Soybean tended to benefit more than corn from being planted within the last two weeks of March and first week of April. Soybean can be more resilient than corn in cooler planting conditions and do not always require a perfect stand like corn to maximize yield.

■

On average, for both corn and soybean, 95% of maximum yield was achieved if planted by April 26, 90% of maximum yield was achieved if planted by May 7, and 80% of maximum yield was achieved if planted by May 29. However, the variance in yield potential drastically increased as planting date was delayed.

Top 5 Corn Insights 1. Highest corn yields continue to be achieved with early planting dates, and the response to ATS and starter fertilizer is greatest when planting early into cooler soils. 2. Nitrogen was best managed when banded beneath the future crop row in the fall and protected with a nitrification inhibitor. Soil moisture was not adequate to sufficiently move sidedressed nitrogen to the rooting zone. 3. Zinc application through the planter box, in-furrow, or early foliar all had positive impacts on yield. 4. Early fungicide and foliar nutrition helped prime the plant to better withstand the drought conditions through midvegetative stages. 5. Season-long foliar management was a viable tool for addressing transient nutrient deficiencies during periods of peak demand, especially in dry soil condition and at high plant populations.

Nitrogen Timing and Source Location: BRANDT Research Farm – Pleasant Plains, IL Summary: ■

To maximize yield potential, the corn crop requires a significant amount of N available in the soil near the row once the nodal root system begins to develop.

■

Nitrogen stabilizers or split applications of N can be used to better time the availability of applied N with crop demand in-season.

■

All nitrogen treatments produced similar yields except when applying all the N between the rows at the time of planting.

■

With the dry weather following planting in 2023, it is suspected that there was insufficient soil moisture to move N to the roots when applied between the crop rows.

Treatments: ■

All treatments were balanced for 160 lbs N/ac.

■

Fall: NH3 band injected directly below the future crop row with N-Serve (1 qt/ac) or Centuro (5 gal/ton).

■

Spring: UAN-28 applied with coulter directly between the rows with Anvol (0.75 qt/ton) immediately following planting.

■

Sidedress: UAN-28 applied with coulter directly between the rows with Anvol (0.75 qt/ton) at the V4 growth stage.

Continuous Corn Nitrogen Rate x MicroSURGE® Location: BRANDT Research Farm – Pleasant Plains, IL Summary: ■

MicroSURGE dry corn inoculant contains Azospirillum sp. which colonizes at the root surfaces and fixes atmospheric N into ammoniacal N than can be taken up and utilized by the plants.

■

Averaged across N rates, MicroSURGE increased corn yields by 10 bu/ac.

■

The greatest yield increase, in response to MicroSURGE, was at the 150 lbs N rate.

■

It is expected that N supplied by biological N fixation can help meet crop N demand in environments where N is limiting. However, it is not likely that biological N fixation can serve as an adequate replacement to synthetic N fertilizer in low-N environments.

■

Optimal N rate was between 150-200 lb N/ac.

TREATMENTS: ■

17th consecutive year of continuous corn.

■

Fall applied NH3 with N-Serve for 0-300 lbs of total N.

■

Within each N rate, corn was assessed for its yield response to MicroSURGE dry corn inoculant.

Skip-Row Solar Corridor Location: BRANDT Research Farm – Pleasant Plains, IL

Summary: ■

The concept of skip-row solar corridor planting configurations is to allow more sunlight to reach the lower canopy, which is the source of energy for the lower stalk and roots.

■

Two studies were established at the research farm in 2023 to evaluate any yield advantage to different row spacings, plant populations, fertilizer placement, and hybrid selection in a skip-row solar corridor system.

■

In Trial 1, skipping every third row decreased yield by 9.1 and 23 bu/ac in 20” and 30” row spacings, respectively. In skip-row configurations, yield was increased by 8.7-17 bu/ac when fertilizer was concentrated to only the planted rows rather than every row.

■

Skip-row configuration decreased yield across the 5 hybrids in Trial 2, and the yield decrease was more drastic as the in-row population increased. Similar or higher yields were achieved for 3 of the 5 hybrids in skip-rows when the in-row population was maintained at 44,000 plants/ac (29,333 plants/ac total population), suggesting the skip-row solar corridor may require a lower total population than in standard 30” row spacing to achieve maximum yield.

■

Past research farm data has shown that narrowing row spacing (i.e., switching from 30” to 20” rows) increases the optimal plant population because the plant-to-plant spacing within the row decreases. Opposite of narrowing row spacing, switching to a skip-row configuration increases the plant-to-plant competition within the row.

■

Multi-year data has shown that sizable yield increases can be achieved with skip-row configurations at high seeding rates when under optimal growing conditions.

BRANDT EnzUp Zn with Starter Fertilizer Location: BRANDT Research Farm – Pleasant Plains, IL

Summary: ■

Starter fertilizers can help meet early-season crop nutrient demand prior to adequate development of its nodal root system.

■

Zinc is the most common micronutrient deficiency in corn and is important for nitrogen assimilation, protein metabolism, and auxin synthesis. Auxins are growth hormones that stimulate cell elongation, which is why Zn is especially important during rapid vegetative growth and dry-matter accumulation.

■

Soil temperature impacts Zn availability, which is why even in soils with adequate zinc levels we see responses to row-applied zinc when planting early. Additionally, high soluble phosphate levels (e.g., starter fertilizers) can induce zinc deficiency.

■

Growth responses from Zn at planting were observed at the research farm through longer internodes and taller plants.

■

Minimal response was observed from phosphorus containing starter fertilizers 5-12-0 and BRANDT EnzUp P DS at planting without the addition of Zn.

■

Compared to 5-12-0 starter fertilizer alone, BRANDT® Sequestar® 9% Zn, BRANDT EnzUp Zn, and BRANDT EnzUp SeedFlow Zn increased yield by 6.6, 9, and 12.1 bu/ac, respectively.

■

BRANDT EnzUp SeedFlow Zn is a convenient product for planter box application that combines Zn and enzymes in a dry powder micronutrient encapsulation for improved seed retention and fluency.

Treatments: ■

5-12-0, BRANDT Sequestar 9% Zn, BRANDT EnzUp Zn, and BRANDT EnzUp P DS were applied in-furrow with the planter in 5 gal water/ac.

■

BRANDT EnzUp SeedFlow Zn was applied to the seed in the planter box at 2 oz/unit of seed.

■

All treatments, including the untreated plot, received 10 gal ATS applied 2x0 with the planter.

Zinc Plays an Important Role in Corn Production Role of Zinc (Zn) in Corn Zinc is critical for the development of corn and has several important roles including: ■

Enzymatic functions - Many enzymes include zinc as a cofactor, like alcohol dehydrogenase, superoxide dismutase, carbonic anhydrase, and RNA polymerase. In these cases, it is indirectly evident that zinc deficiency inhibits protein synthesis.

■

Nitrogen assimilation and protein metabolism – Approximately 10% of proteins in plants require Zn for structural function and integrity. Low Zn supply limits the plant’s ability to convert amino acids to proteins. Additionally, the rate of protein synthesis is drastically reduced in Zn deficient plants.

■

Auxin metabolism – Zn deficiency causes reduced auxin levels, leading to little leaf syndrome, stunted growth, and reduced shoot elongation. An example is indole acetic acid (IAA). Indole requires Zn to produce tryptophan which leads to IAA. Reduced Zn leads to higher stress responses, causing production of more free radicals, leading to the degradation of IAA.

Growth Stages Where Zinc is Critical. Zinc is a vital micronutrient for corn throughout its growth, but there are certain key stages where its availability is particularly critical: Germination and Seedling Stage: n During germination and early seedling growth, zinc is crucial for root development and the function of enzymes that drive growth and energy production. ■

Vegetative Growth Stage (V3-V8): n As the corn enters the rapid vegetative growth phase (from the third leaf stage (V3) to around the eighth leaf stage (V8), zinc is essential for the formation of chlorophyll and carbohydrate metabolism. ■

■

Reproductive Stage (Tasseling and Silking): n During the reproductive phase, particularly at tasseling and silking, zinc plays a vital role in pollen formation and viability.

Grain Filling Stage: n In the grain filling stage, zinc is important for the development and maturation of kernels. It contributes to protein synthesis and the formation of starch in the kernels, impacting the final yield and quality of the grain. ■

Conditions Leading to Zn Deficiencies ■

Diffusion is the primary mechanism for transporting Zn to plant roots, so any factor that inhibits root development will impair Zn uptake.

■

Climatic factors resulting in reduced Zn uptake include cold, wet soils particularly early in the growing season. Plants may outgrow this early-season deficiency; however, some yield loss may have already occurred.

■

Waterlogged soils can also have lower available Zn levels due to the reduced conditions and subsequent precipitation of insoluble Zn compounds.

■

High soil phosphorous (P) levels and P fertilization rates can induce Zn deficiency in soils with marginal levels of Zn.

■

High soil pH decreases soluble zinc in soils, pH’s greater than 7 are often associated with Zn deficiency.

Identifying Best Criteria for Zinc Applications to Corn There are several criteria growers can look at to determine if crops are going to be responsive to Zn applications. One of the most common resources are published soil test levels and tissue test levels. Soil test values for critical levels vary but are often reported to be between 0.75 to 1.5 ppm of available Zn (M3 Test). The optimal published zinc concentrations tissue test typically ranges from 30 to 70 ppm for modern high yield corn varieties.

Summary: Application of BRANDT Smart Trio or BRANDT Smart Zn at V4 to V5 boosted yield across all locations by an average of 8.6 bu/ac compared to control. ■

23 out of 24 treatments (95%) responded positively to foliar BRANDT Smart Trio and BRANDT Smart Zn at V4 to V5. There was a statistically significant yield increase at a 90% confidence level for 10 of 24 treatments (41%).

■

Soil test levels below 1.5ppm Zn and P:Zn ratios above 15:1 were good predictive tools that the fields would be responsive to foliar applications of zinc. However, sites that had values above 1.5 ppm Zn soil test values and P:Zn ratios that were ideal also reported improved yield results with foliar Zn applications.

■

There was a significant decrease in Zn levels for the whole plant analysis (V4 – 6) vs tissue test values at R1, with R1 values being much lower. Utilizing whole plant analysis at early V stages may not be a good predictor when used alone. This dynamic should be explored more.

■

11 of 12 locations had Zn tissue test levels below 30 ppm at R1. Fields sites that have historically shown tissue test values <30 ppm Zn may be good candidates for zinc applications.

proposed sufficiency ranges for P:Zn. Research Trial Results A zinc fertility study was carried out across 12 locations in South Dakota, Minnesota, and Iowa. The study included 24 treatments of foliar zinc applications utilizing BRANDT Smart Trio and BRANDT Smart Zn. Phosphate (P) application rates were in sufficient amounts as not to be limiting at all sites. Nitrogen (N) application consisted of 180- 240 lbs/ac N dependent on location and grower. 8 sites exhibited low to moderate soil zinc deficiencies with soil test values < 1.5 ppm of Zn and / or P:Zn soil ratios higher 15:1. Further, 11 of the 12 sites had Zn tissue test levels below 30 ppm at R1. Soil and Tissue Test Values Indicated in table to the right.

Progressive Foliar x Plant Population x Row Spacing Location: BRANDT Research Farm – Pleasant Plains, IL

Summary: ■

Historical grain yield increases in corn have been matched with higher planting populations. Higher stands of corn require hybrids with greater density stress tolerance and precision placement of nutrition.

■

Narrower row spacing has been proven to be a better arrangement of higher plant populations and was the case at the research farm in 2023. The greatest responses to 20-inch rows were at planting densities of 44,000 and 48,000 plants/ac, which are well above typical seeding rates in the Corn Belt.

■

Averaged across plant populations and row spacing, application of fungicide with BRANDT Smart System products increased yield by 20.6 bu/ac when applied at V5 and an additional 8.8 bu/ac when a second application was made at V12. On average, there was no response to a third foliar application made at R2. However, the response to the 3-pass system was greatest at 52,000 plants/ac in 20-inch rows and 48,000 plants/ac in 30-inch rows, where crowding stress was the highest.

Boron in High-Yield Corn Production Boron’s Role in Corn Growth: ■

Critical growth stages: Boron is crucial in high-yielding scenarios, especially between the V10-V14 growth stages. Severe deficiencies (below 6 ppm, as per tissue tests) can lead to poor pollination due to delayed tassel development and reduced pollen viability.

■

Peak accumulation period: A substantial 65% of a corn crop’s total B is absorbed over just 1/5th of its growing season directly ahead of pollination, emphasizing the high demand for B ahead of reproductive growth (Figure 1).

■

Kernel development: Insufficient boron in the plant (below 9 ppm) from the blister (R2) to dough (R4) stages can hinder kernel development. Boron facilitates carbohydrate metabolism and sugar transport through membranes.

■

Availability in the soil: Boron deficiency correlates with soil type, organic matter, rainfall, and pH. It’s highly soluble and easily leached in well-drained or excessively irrigated soils. Its availability decreases in alkaline-calcareous soils and under drought conditions.

Boron Synergism with Potassium and Fungicides: ■

Why consider potassium application with boron: Potassium (K), like B, is in peak demand directly ahead of tassel and is vital for sugar transport in the plant. Nearly 75% of a corn crop’s total K requirement is accumulated prior to tassel (Figure 1), and, even with adequate soil test levels, potassium uptake through the roots may not be sufficient during periods of peak demand.

■

Synergistic response with fungicide: Boron applications typically perform well in combination with fungicides. A net positive increase in photosynthesis and carbohydrate production from the fungicide in combination with improved sugar movement and partitioning from the B and K can effectively improve yields.

Effective Application Strategies: ■

Optimal timing: The best results for boron application are seen between V10 and flowering (VT/R1), aligning with its peak demand and often coinciding with fungicide and insecticide treatments.

■

Product selection: Choose boron products that ensure effective mobility within the plant. BRANDT Smart K B, with BRANDT Smart System delivery technology, prevents B from binding to cell walls, enhancing translocation to developing kernels and growing points.

Corn Yield Response to Boron at VT/R1 Summary: Application of BRANDT Smart K B at VT/R1 boosted yield by an average of 8.8 bu/ac compared to fungicide alone. ■

■

Fungicide, K, and B played a large role in stress mitigation and late-season plant health during the dry conditions experienced in central Illinois in 2023. Because of the high demand for K and B prior to pollination, a foliar application can help overcome periods of transient deficiency and assist grain fill.

Top 5 Soybean Insights 1. With the use of a good seed treatment, soybean can be resilient in early planting conditions. Historical research farm data continues to show that maximum soybean yield is achieved when planted in early April. 2. Variety selection was crucial. Longer maturity varieties took better advantage of late-season rains to maximize yields. 3. The combination of starter fertilizer and planter box treatment including molybdenum and inoculant impacted nodule production and early vegetative growth and color. 4. Foliar application during flowering and beginning pod development continues to provide the largest impact on yield by reducing flower and pod abortion and protecting the trifoliates near the middle of the plant. 5. Foliar applications near R4-R5 aided in protecting against pod-feeding insects, extending photosynthetic capacity, and assisting carbohydrate partitioning to the pods.

Summary: ■

The application of BRANDT Smart Quatro® Plus or BRANDT Smart Sulfur Plus at V4 increased average yield by 6.5 or 5.5 bu/ac, respectively.

■

Application of Zn, Mn, B, and Mo during early vegetative stages can assist with nodule formation, nitrogen utilization, herbicide metabolism, and photosynthesis.

■

At R3, the application of BRANDT Smart K B and BRANDT Smart Trio with fungicide increased yield by 5.5 bu/ac compared to the untreated control and 3.2 bu/ac compared to fungicide alone.

■

Application of BRANDT N-Boost 5 with fungicide increased yield by 2.5 bu/ac compared to fungicide alone.

■

BRANDT Smart System products are designed for superior compatibility with crop protection products and maximum foliar uptake.

■

Pairing BRANDT Smart K B with a fungicide application improves plant health and photosynthesis, maximizes nodule production and plant utilization of N, and assists pod fill.
