Nitrogen Stress and Rain

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.

Maximize Your Yield With Foliar Nutrition

5 Considerations for Effectively Applying Herbicides

Spring is Right Around the Corner

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.

Dicamba Training

Due to label changes all producers that plan to utilize  Xtend® technology are now required to take a class on proper Dicamba usage training.

It is a requirement for ALL applicators who use Dicamba in-crop on Soybeans. You have to be a Certified Pesticide Applicator to both buy AND apply (this includes mixing and loading) these products.

We will continue to post any other future meetings in our area. This is the first of several to come. By attending one meeting this year, you will satisfied the requirement.

Monsanto is offering this class in Green Bay.

Tuesday, Febuary 13 – KI Convention Center – Green Bay, WI

9:30 am to 11 am or 1 pm to 2:30 pm

The Importance of Drift Reduction Agents

New Application Requirements

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.

Advantages to Fall Fertilizer

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.

K is for Potassium, Why soil K levels need monitoring.

 

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.
