Tips for agronomy

A side dressing treatment might just do more than boost nitrogen. Farmers who want to strengthen their yield numbers or lower stress, can get other nutrients in the side dress application.

Since AgroLiquid products are getting more and more compatible and flexible, farmers augment with potassium, calcium, micro-nutrients, phosphorous, sulfur and High NRG-N at side-dress.

If you add such a treatment mid-season, this might renew plants that are struggling or that have stalled so that they can handle holding a heavy amount of fruit. We usually remember to check for K, N and micros, but it’s important to also remember P. Think of N as the fuel and P as the engine. When photosynthesis is combined with phosphorous by ATP, it makes the necessary energy to help a plant grow and be healthy.

Farmers who grow fruit, vegetables or trees can use fertigation to give nutrients and water – giving all the nutritional needs of the plant at one time without the chance that staging treatments, antagonism or precipitant would cause problems.

A blueberry farmer faces many challenges because of his or her environment. Normal fertilizers are very limited. P is usually not available, calcium is often deficient and Iron and Manganese are limited. Also, modern fertilizers have chlorine and salt that actually limit the crops and make it so the fertilizer can only be applied in certain ways. On the other hand, AgroLiquid products are not so changed by a different environment and are the best on the market for fliexible application processes. If you utilize both Agro-Culture Liquid Ferilizers and nutrient management, you are on the road to a higher quality, higher yielding crop. For the last two years in a row, farmers who use Agro-Liquid have been the recipients of production awards.

Your soil’s pH will affect every crop and therefore, it’s potential yield. It’s necessary to amend the soil at times. The best time for this is autumn so that the process can take hold before planting. Ammending the pH makes it so that nutrients can be present – as they aren’t keen on sticking around a sterile environment. Each nutrient feels the effects to the soil’s health, so managing your pH makes it less likely for nutrients to have a negative reaction to something in the soil, making them useless to you. While you’ll almost never find a perfectly-balanced field, the steps you take to reach balance will give your crop the greatest chance to meet its potential.


  • Apply nutrients next to the roots where the plant can absorb nutrients best.

  • If a field has an unbalanced pH, you may have to apply nutrients more than once.

  • Watch for pH-caused deficiencies.

The beauty of Agro-Culture Liquid Fertilizer is that it can increase production in crops in poor pH environments, or in ideal conditions.

f you want ideal crop yield, you have to think about micronutrients. These usually cost more than nitrogen, potassium and phosphorous and the deficiencies are not as pronounced. These realities make some farmers suspect that they’re not really benefiting from this aspect of fertilization. To further complicate the issue, there have been, historically, issues with application. Some manufacturers of such fertilizers didn’t ensure that N-P-K stayed evenly mixed throughout the fertilizer, making it so that the grower couldn’t be sure the field was getting an even share of the needed nutrients.Therefore, cost and difficulty have been prohibitive in using micronutrients, though they are essential to improve the vitality and yield of your crops.

Sulfur, technically being a “secondary” nutrient, is often overlooked. Yet, when needed, it should be treated as a primary unit. Without the right amount of sulfur, plants are unable to absorb primary nutrients. Sulfur should be an importance part of your fertilizer program.

We often just consider nitrogen as a nutrient to side-dress corn. But side-dressing is a great opportunity to supply many nutrients to our crops. Many times there is a lack of potassium (especially in sandy soil) and a side-dress of K may just supply the needed nutrient to plant at just the right time. In the same way, micro-nutrients and secondary nutrients can be side-dressed. Many are aware of the need for sulfur and manganese for Roundup ready crops. To meet the need, supplying M via side-dress is a perfect way to treat the crop, and can be done at the time other Roundup applications are done.

When planning post emerge crop protection, it’s a good idea to add supplements to give added nutrition. Do this by switching out several gallons of water with a fertilizer that you know is compatible with your plan and is good for foliar application. There are many things to consider: timing of application, water pH, growth stage, and formulation of nutrients. If you carefully consider these factors, you will see an economically satisfying yield response in your crops.

You may even find that your corn could benefit from a foliar-applied “booster” of nitrogen. This may happen if your plants are short on nitrogen or if you think you might reach beyond your yield goal. Consider adding a foliar supplement of nitrogen, as it can be helpful for many reasons.

Tips for foliar-applied nutrients:

  • Plant leaves absorb nutrients better before temperatures reach 86 degrees.

  • Don’t forget that plants also absorb through the underside of leaves. Try this out by using small nozzles with high pressure.

  • Smaller droplets cover more foliar surface making it more likely to absorb more nutrients.

  • Salt-index can tell you how likely a product might hurt the plant tissue. Some products aren’t good for foliar application.

  • Don’t overdo it! Plants can only benefit from a little foliar-absorbed nutrition. If you apply too much, you might burn the plant. You will not see a direct increase of production based on how much nutrition you apply. There is a limit, so be realistic.

Studies have shown that if you use Roundup regularly, you will probably have too little manganese. However, ACLF has demonstrated that adding manganese with your regular Roundup usage doesn’t jeopardize weed control – so add some manganese.

Since hybrids today are quite expensive, it’s necessary to make sure you get the most production out of your seed money. It’s likely to have a flat yield curve after applying large amounts of just one nutrient. So balance is key. Increase in one input may call for investment in another limiting nutrient.
