In cotton, the timing of applications is key. In a 2021 study conducted in Mantee, MS, all foliar applications happened at early bloom, which is a critical stage in a cotton plant’s life cycle.

This cotton was exposed to very heavy rainfall throughout the growing season and was 6′ tall in places, which is considered “rank” cotton. With so much vegetative growth, you would expect to see boll rot and fruit abscission, however in this study, the treated cotton did not experience any of this. The timing of the applications in this study was key.

Key findings from this research:

• The application of boron along with the micros and sulfur applied during early flowering contributed to the fruit retention and root health of the plant, and therefore the yield, in this overly tall cotton crop.
• If no other applications can be made in season, getting these products out at a critical timing point is key. The first 40 days is the most crucial and in this trial, the timing was the direct correlation to the yield
• Adding LintBooster to your tank mixes during peak reproductive growth can improve both overall yield and return on investment.

Lint Booster is a low-volume plant nutrition product designed to supply the N-P-K, secondary, and micronutrients cotton needs to thrive. With all the nutrients cotton plants need contained in one low-volume formula, Lint Booster makes it easy to maximize boll retention and extend fill.

 

 

 

 

Kapitalize is a fast-acting potassium with added calcium and sulfur designed to be foliar applied during the critical reproductive stages of plant growth. Kapitalize has been formulated to be combined and immediately applied with other AgroLiquid products.

Soybeans require large amounts of potassium (K), sulfur (S), and calcium (Ca). They also require micronutrients such as manganese and iron to meet their yield potential. In addition to soil applications of those nutrients, soybeans often respond to foliar applications. Sure-K® and fertiRain® products are well suited to provide cost-effective crop nutrition when applied as foliar treatments.

Sure-K

Sure-K was applied for 10 consecutive years in a corn-soybean rotation as a soil applied treatment and as a foliar treatment. Over the 10 years of the trial, the foliar application of Sure-K at 3 gal/A consistently performed as well as Sure-K applied at 5 gal/A in-furrow.

fertiRain

When applied alone, fertiRain provides excellent potassium nutrition along with nitrogen, phosphorus, and sulfur. Application timings are flexible, and it can be tank mixed with many crop protection products.

The Right Mix

Sure-K and fertiRain can be applied alone, or in combination with each other or other crop nutrients. Soybeans will often require more potassium than fertiRain alone can provide, and fertiRain can provide additional nitrogen, phosphorus, and sulfur to Sure-K.

Performance Consistency is Key

Product performance consistency is as important as individual trial results. AgroLiquid has evaluated yield response to foliar applied Sure-K across 165 locations from 1998 – 2019. Those trials showed a high level of performance consistency and economic benefit. The economic response was calculated using the soybean market price and fertilizer costs appropriate for the year each trial was conducted.

FertiRain is a valuable tool for sugarbeet growers

Nitrogen (N) management in sugarbeet production is crucial, having just enough N results in good sugar yields, but with too much N beet tonnage increases while extractable sugar decreases. Growers are paid on pounds of actual sugar produced, not beet tonnage. In our research over time we have found that foliar nutrition reliably increases sugar production, perhaps most notably FertiRain. With a perfect foliar ratio of N, phosphorus, and potassium, plus micronutrients formulated for efficient absorption through the leaf surface, FertiRain is proving itself to be a valuable tool for increasing sugar yields.

In 3rd party research in Minnesota during 2020, FertiRain at 1 gal/A added to Cercospora Leaf Spot fungicide treatments increased sugar yield by 1,000 lbs/A, with no detrimental effect on the efficacy of the fungicidal treatments.

These results support previous research at the North Central Research Station (NCRS) demonstrating the effectiveness of FertiRain of increasing sugar yields.

Reaching a crop’s full growth and production potential is about more than preventing deficiencies. It means making a complete range of nutrients available to the plant at every stage. FertiRain is a complete multi-nutrient liquid fertilizer designed for dynamic plant nutrition and optimal growth. With macronutrients, secondary nutrients, and micronutrients all included in carefully measured amounts, FertiRain supports all of the plant’s needs and growth stages. Combining nitrogen, phosphorus, potassium, and sulfur as the primary nutrients, we have included the crucial micronutrients iron, manganese, and zinc to support healthy plant metabolism at just the right time. FertiRain has been shown to increase plant sugars in other crops as well, including forages and fruit crops.

Foliar applications of Sure-K when soybeans are beginning to flower (R1) have a proven yield benefit. This timely application of Sure-K provides available liquid potassium at peak usage.

This trial from 2019 in LyCene, KS shows an increase of 3.4 bu/A with just 2 gal/A of Sure-K added to the grower’s standard treatment of 100# MAP and 100# potash.

All treatment: 100 lb/A potash + 100 lb/A DAP

Additional benefits of working with Kalibrate:

• Low use rate
• Ease of application
• High average return on investment
• Mixes with many other fertilizers and crop protection
• Proven response on high potassium soils

Research trials at the North Central Research Station (NCRS) have long shown that foliar fertilizers can push several more bushels of soybeans per acre. But like anything dealing with plant nutrition, it should be “customized” to plant and soil needs. See trial results below from the NCRS .

Because of the wet spring that we all remember from last year, these soybeans were planted late. Thanks to an extended warm and dry fall, yields were surprisingly very good. The low soil phosphorus made the application of Pro-Germinator at planting necessary. Additionally, we often have not shown a response to foliar-applied potassium if another nutrient like phosphorus is limiting, like Liebig’s Law says.

The soil potassium level was not bad, but the % Base Saturation indicated that there could be a response to added potassium. Sure-K is AgroLiquid’s best nutrient product for foliar-applied potassium, and it did result in a yield increase. FertiRain is an excellent foliar product, but is not as effective as Sure-K for feeding potassium. There has been some suggestion of yield response with foliar-applied C-Tech due to the carbon and biologicals. But there was not much response in this experiment where potassium was the missing link.
