This week’s rain has been a blessing and a stressor together. With regards to the rain, I shift my summertime thoughts of weed and pest management to that of Nitrogen. Today’s corn crop ranges from v2-v7 and at this stage has taken up 5-10% of its total nitrogen need, meaning we have a lot of nitrogen to still take up this summer. This week’s rain ranged from 2-5 inches dependent on location. This was roughly 15-30% of the total rainfall this season, meaning nitrogen flow could be quite high in fields with a lower ability to hold its nitrogen. We know that the transient flow of nitrogen is quickly moving due to its negative charge and only moves in a vertical plane through the soil, so as the fields begin to dry out later this week, keep an eye on fields yellowing or showing signs of nitrogen stress that could affect yields if the bulk of your nitrogen has been applied already.
Applying foliar nutrients gives you the ability to apply nutrients the plant needs as it is developing. Plants have increased demands for certain nutrients during growth stages. Applying the foliar nutrients at the ideal time and in the appropriate form, improves plant health and development to increase overall crop yields.
Foliar nutrition should be an important part of your overall crop fertilization strategy to maximize crop yields. Be proactive with foliar nutrition rather than just using it to fix a problem. If you wait until you see a nutrient deficiency, a large amount of potential crop yield will have already been lost.
There are several factors to consider before and during herbicide spray application. Taking the appropriate steps to prepare for a successful application can save time, money and effort. While spray requirements may vary based on crop, location and herbicide formulation, there are steps that should be taken to ensure the best protection against weeds during the current crop season and to protect the effectiveness of the herbicide long term.
Mother Nature plays an important role in the success of herbicide application. In addition to the preventive and arbitrary actions necessary to increase herbicide effectiveness, working with natural conditions is extremely beneficial and mandatory since we do not control the weather or other natural factors.
Here are five considerations to get the most benefit when applying herbicides in the field:
With the planting season around the corner , have all the preparations been made to have maximize your profitability. Will you get a return on your investments and have we made the decisions that will create positive results? We can’t control the weather , what it does or does not do. We do control planting our seed in the right places at the right population, using the right crop protection products and making the right fertilizer decisions. Getting our equipment up to date and ready to hit the fields when they are fit to plant. There are a lot of variables deciding return on investments and profitability .We need to make the right choices that put us in the situation to sustain positive results. Contact your CHS Larsen Agronomist and YieldPoint Specialists to help you maximize your profitability so when planting gets here you are ready knowing the decisions we control are done and now it’s up to mother nature.

The agriculture industry understands that crop protection is necessary to ensure optimal yields, but we also understand that the damage caused by off-target drift can be detrimental. Current herbicide regulations are becoming more stringent to reduce off-target drift and minimize potential damage to surrounding plants or species, making it more important than ever to take the necessary precautions to make sure the herbicides only make contact with their intended targets.
Drift reduction agents (DRAs) reduce off-site movement of herbicides. This term has been around for a long time. However, with the approval of the new herbicide technologies, DRA has also come to be an industry term for an adjuvant or other product that is approved to be tank mixed with the herbicide to mitigate drift. DRA’s create larger droplets for the tank mix to prevent off-target movement during the application or from being carried away from the desired target after the application.
Minimizing drift, means less damage to surrounding crops and other unintended targets, which is better for everyone. With drift control being a top priority in the agriculture industry, approved DRAs are required with the new dicamba herbicide applications.
The new tank mix and DRA regulations have changed the way new products are developed in the agriculture industry. While previously the focus was on reducing small droplets and creating more uniform droplet sizes, with the development of new chemistries and herbicide technology, the necessary standard today is to develop adjuvants and other DRAs that create the larger droplets necessary to reduce off-target drift.
Optimize DRA Use for the Best Results
Industry professionals agree the proper use of DRAs yield the best results. They also know there are many factors that can affect the efficacy of a pesticide application, including, but not limited to the DRA.
Today’s goals include minimizing off-target application, while trying to maximize the efficacy of the particular chemistries you are applying. This is why product manufacturers are working with industry experts and the EPA to come up with the best solutions for pesticide applicators and growers. However, as you consider your crop protection recommendations for next season, keep in mind that there are factors beyond the tank mix that in cooperation with each other, can also affect off-target movement.
These other factors include:
Spray nozzle selection
Volume and pressure of sprayer
Pesticide tank mixes’ impact on droplet size
In the past, many people thought that if you have a product that minimized drift, it worked uniformly regardless of the other parameters. Now there is a much greater awareness among experts that all these factors in combination with each other have an important impact on the outcome of the spray application. This means an application can have quite different outcomes, even if only one of these factors are changed.
This is why it is important to make sure you follow the application requirements for each product. The manufacturers have online resources that are updated regularly and product labels are clearly marked with specifications and regulations for spraying conditions, boom height, mixing instructions and additional information. Be attentive to the label to ensure that you are using the products correctly and in turn, reducing the potential for off-target drift.
Proper use of DRAs with approved tank mix partners is important and helps avoid damage to crops in neighboring fields and other species. It will also allow the industry to continue using these herbicide technologies as part of an effective weed management plan.

CHS offers TRAPLINE PRO™ II, a DRA approved adjuvant with tank mix partners including XtendiMax® With VaporGrip® Technology, Engenia®, and FeXapan™ herbicide Plus VaporGrip® Technology. TRAPLINE PRO II contains a water conditioner, surfactant and defoamer and also includes unique drift control abilities that are approved for use with glyphosate, dicamba, 2,4-D and other herbicides with DRA requirements. In addition to being an all-in-one adjuvant, TRAPLINE PRO™ II has a convenient low use rate of 4 to 5 pints per 100 gallons of water.TRAPLINE PRO II has also shown to be a beneficial adjuvant with other herbicides, in addition to glyphosate and the new dicamba products.
There have been changes in the applicator requirements if you are applying any of the new formulations of dicamba to RR2 Xtend soybeans. These products currently include Xtendimax, FeXapan, and Engenia. You must hold a restrictive use applicator license to purchase and apply these products. In addition all applicators must attend an annual group 4 herbicide specific training prior to using these products. We will be keep you informed of training opportunities, so please contact us if you require additional information.
Many ask what are the advantages of fertilizing in the fall over spring? Usually in the fall there is less moisture to deal with then in the spring, which means less compaction from machinery. You also have less of a chance of runoff due to less rain fall compared to spring.
Fall Fertilizing is also more manageable. Your cooperative is more available with having more time, people and machinery to use and run in the fall. One of the greatest advantages as the Farmer is you don’t have to hold up spring planting while waiting for your fertilizer application.
In addition, fall tillage ensures that the fertilizer is incorporated into the root zones. All in all, fall tillage can save you time, money and the stress of getting your fields prepared and planted.
Lastly, you have a great opportunity to save money with our Fall Fertilizer financing programs. Contact your Agronomist today to ask about our Fall Fertilizer programs or to schedule your application.
Soil sampling for pH has become a staple in decision making on farms across the state that grow alfalfa. The second soil test nutrient that is monitored heavily is phosphorus, this is due to the need to maintain soil P levels for compliance and soil conservation. The forgotten tool in a routine soil sample is the soil K level. Potassium is the key nutrient that drives yields in corn silage, alfalfa, soybeans and grain corn.
The majority of potassium stays in the cells of plant tissue in the fall, meaning that any removal of Stover yields a large export of soil K from fields. Rock River Labs out of Watertown have followed trends in soil K levels. Their research has shown the levels of soil K have been increasing in the low and very low categories over the last 5 years for a total of an 8% increase in these categories. This paired with the research by UW Madison has shown a decrease level of 1.5ppm / year. This is problematic to crop production as the remedial process for soil K can be a 5-8 year adventure.
So my advice for you is to monitor your soil K levels before they become low or very low, and affect your yields for 5-8 years. Soil K removal for 60 bushel beans is 70lbs K , alfalfa at 5 ton is 245 lbs K, and corn silage at 20 ton is 145lbs K . Converted to Potash this is 115, 395, and 230 lbs respectively. This can become a huge amount of K removal from a field in a 4/5/or 8 year rotation. Ask yourself if your current rotation and fertility programs are able to address the yields that you have removed from the fields. If you feel that you have not replaced the soil K levels that have been removed, contact myself, or your CHS Larsen agronomist to talk about monitoring your soil K levels with soil testing and proper fertilization.
