Then, consider applying a low rate of a liquid product that contains zinc for quick, early availability in any crop. Grid or zone sample to set up variable rate application as the zinc level may vary greatly across your fields. This year, consider building your soil to get your zinc levels up. Keep in mind that like phosphorus, zinc doesn’t leach in most soils, so as long as you prevent soil erosion, your zinc should be there until your crop eventually uses it. We broadcast zinc sulfate in the fall and normally see it show up on the soil test by the next fall or earlier. On our farm, we use variable rate application to target areas in our fields that fail to meet the 10:1 phosphorus to zinc ratio and also have at least 1.8 ppm. If you need to build your soil and increase by several parts per million, consider dry zinc sulfate (35.5% zinc and 17% sulfur) at a cost of about $0.75 per pound. That way even when the ground is cold, we still get good levels in the plant early in the season. Even where our zinc levels are great, we still use products like Micro EX that contain low rates of zinc and other micronutrients. 9% liquid zinc chelate is about $4 to $5 per acre for 1 quart, which delivers about 0.25 pounds of zinc. If you are on a one-year rental contract or if you just need fast uptake of zinc, using a liquid zinc product is great. Zinc Removal in Corn, Soybeans, and Wheat Cheaper Way to Get Zinc The amount in the Grain column leaves the field when the grain is hauled away. Here’s a list of three crops and how much zinc it takes to produce the grain and the stover. For example, if the Bray P1 phosphorus level was 50 ppm, we’d recommend having at least 5 ppm of zinc. With soils high in phosphorus, we’d shoot for no more than a 10:1 ratio of available phosphorus to zinc. Our typical recommended level on a 6” Midwest Labs soil test (using a DTPA extraction method) is 1.8 to 3.5 parts per million (ppm).

High levels of phosphorus can easily tie up your soil’s zinc.

Using liquid zinc in corn and then nothing the following year in soybeans is almost certainly depleting the soil if you are getting high yields.

As you can see in the chart below, that may not be as much as you are removing from the field each year, and especially in a two-year period, corn followed by soybeans.

If your 9% zinc chelate weighs 11 pounds per gallon, 1 quart of liquid contains just one-quarter pound of actual zinc.

Is this enough zinc for your crop? Do I need zinc for other crops, too? Is there a cheaper way to feed the crop? Why is zinc so important? Functions of Zinc

Many farmers we know use 1 quart of chelated zinc Tub Total Nitrogen (N).Zinc is likely the most frequently applied micronutrient. Bag Total Nitrogen (N).Īvailable Phosphate (P 2O 5).

How to Useĭissolve the following amounts in 1 gallon of water. The nutrient package in the All-Purpose 20-20-20 is designed for optimum absorption by the leaves when sprayed at the recommended rates however, a root drench is just as effective and will leave little to no salt build up in the media. Therefore, it is recommended when using this formula over long periods (greater than 3-4 months) of plant growth, alternate with a lower Phosphorous source such as rainwater, calcium nitrate or other lower phosphorus fertilizers.Īpplication of this fertilizer can be used as a root drench or foliar spray. Long-term use of high Phosphorus formulas can lead to plant stretch in some plant varieties. These environments allow the roots to take up the nitrogen sources most effectively. Preferably, it should be used on soil-based media, rather than on soilless media, primarily during warmer months, indoors or in warm-climate regions. The design of the formula uses nutrients that provide strength to the plant, as well as, lush green growth. It can be used as a constant liquid feed or periodic feed, alternating with water or rain to provide the plant with a boost of balanced nutrition. Its 1:1:1 nutrient ratio makes it good for almost any stage of plant growth. Just as the name suggests, Jack's All Purpose 20-20-20 is a balanced formula applicable to a variety of growing material.
