With the planting season starting to wind down, now is the time to plan on how you are going to maximize yields in 2015! We all know commodity prices are not where we would like them to be. The easiest way to combat low prices is to raise more bushels. In this post we are going to talk about Foliar Feeding, how it benefits multiple crops, and Side Dressing, feeding modern hybrids.
Foliar feeding is an easy way to deliver nutrient adjustments in season and fine tuning for those high yield environments. Foliar products are very diverse and range from simple NPK to full assortment of micronutrients that have specific application times based on what they help the plant accomplish and how they accomplish it. In this section we are going to concentrate on foliar feeding corn, soybeans, and alfalfa. The first step and most important part of any foliar program is a good tissue test. When we take our tissue tests we also take a soil sample at the same location to give us a reference of what is in the plant and what is in the ground. Tissue testing gives a base line to create a foliar program and to see what difference our applications have made.
Foliar feeding corn is different than soybeans and alfalfa. Corn has fewer points in which we can help influence yield. A product like Super 72 is a slow release nitrogen source that works well in combination with Zinc and Manganese to be applied with your post herbicide application around V4 to V8. At this time, the corn plant is determining the number of kernels around the ear along with the number of kernels long. If we can reduce stress and nourish the plant at this time we can have a positive effect of this process. Applying Boron prior to pollination can increase the effectiveness of the fertilization process. Boron helps the plant form the tubes in the silk where the pollen grains travel down and fertilization takes place creating the seed for you to harvest. If we can increase this, we can increase the number of seeds per ear. At this same application time we can add another round of Super 72 to help with the increased demand for nitrogen needed during the reproductive stage.
Foliar feeding soybeans take a little different approach than corn. Along with having an additive effect, micronutrients also have somewhat of a curative effect. When applying glyphosate to RR soybeans we have all seen the dreaded, Yellow Flash. This yellow flash comes from the plant digesting glyphosate and in doing so it ties up Manganese (Mn). By adding a product like Soy mix with 3 gallon of our 3-18-18 or 9-18-9 to every application of glyphosate, you can avoid the yellow flash and reduce the stress on the plant. Soybean reproductive stages are another great time to add micronutrients to your soybeans. At this stage of growth the use of the Super 72 is also very beneficial. As we all know the soybean plant fixes its own nitrogen in nodules, in the roots, but the demand for nitrogen in a soybean plant is actually greater than that of a corn plant. Soybeans produce enough nitrogen throughout the vegetative stages, but is at a defect during the reproductive stages. If we feed the plants products like Super 72 and 3-18-18 with Soy mix they can achieve amazing yields. They also put on a lot more pods on the top third of the plant.
Side Dressing Modern Hybrids
Side dressing 32% N is an easy and effective way to feed modern corn hybrids! Most new high yield corn hybrids have a different demand for nitrogen then the hybrids of our past. These new hybrids are designed to put most of their energy into yield and take less during their vegetative phase. In order to push high yields with these new hybrids we need to shift how we feed them! We can still get by with a typical N pass in the fall, but if you want to get the most out of them, we must change! The program a lot of top producers are going to is to put 1/3 to 1/2 of their Nitrogen needs down pre plant, depending on timing to get across your acres. Then use a high quality starter which matches your field's fertility. Follow this with the remainder of your Nitrogen needs as late as you can and still get across your acres. Using nitrogen stabilizers help to prolong the availability of nitrogen to the plants. If possible or necessary the use of highboy to dribble/coulter on 32% N is a great way to push even further towards tassel and pollination. The closer we get to giving the plant its main nitrogen source when it needs it, the more efficient it is and higher yields we see.
The planting conditions this year were great, because of this we have a great stand established. Please, don't let a great start to a growing season drop off. The only way to beat low prices is to raise more bushels!! Give us a call and let us help you achieve a top crop this year with the help of foliar feeding or side dressing with 32% N.
Longnecker Crop Deficiencies APP
A quick reminder about our App! It is mobile application or app, that helps identify crop deficiencies. Once the deficiency is identified it will lead the user to products to help remedy the situation. It is simple to use and allows you to get to the deficiency by picture as well. If you think you know the deficiency, but would like a picture to confirm it, you can do that as well. The mobile application is available for both Droid and iPhone. You can download it for FREE in the Google Play store or the iTunes app store, just search for Longnecker Crop Deficiencies. If you need help with the app please contact Kayle 515-291-3551.
