Application Decisions – Flexibility of SO4 and 98G

98G Application Photo

Using SO4 pelletized gypsum and 98G pelletized limestone in your fertility program allows flexibility when weather limits application season in the fall and spring. Using SO4 pelletized gypsum and 98G pelletized limestone in your fertility program allows flexibility when weather limits application season in the fall and spring.

Considerations for applying 98G

Ideally, 98G would be applied in the fall to initiate pH correction before spring planting occurs, but its rapid reactivity allows flexibility for spring application as well. Regardless of the season of application, one should consider how 98G is applied with respect to other field work. To maximize the efficiency of 98G, the pellets should be applied and allowed to begin breakdown via water (rain, dew, contact with soil) before being worked into the soil with a field cultivator or other tillage equipment in order to target the zone of active acidification — the top 4 inches of the soil profile.

If 98G is being applied for pH maintenance, it can be blended with other flat-rate, broadcast fertilizers to limit trips across the field, or placed into a split bin variable rate application. When the rate exceeds 200-400 lbs/A, it should be a standalone application.

Considerations for applying SO4

SO4 has several options from an application standpoint. Our general recommendation is that it be applied in spring with other soluble fertilizers, however, it can also be applied in the fall and remain available for crop sulfur needs come spring. SO4 can also be used as a rescue application in the spring where visual sulfur deficiency is present. SO4 can be applied any time after emergence and with the right amount of precipitation, will result in plant green up in less than a week. Because SO4 has a very low salt index relative to other fertilizers, it will not injure/burn young crops after broadcast application. 

Regardless of application scenario, SO4 works best when it is left on the soil surface. Since sulfate is an anion (negatively charged), it has potential to leach, and letting the product work from the surface downward will result in the best sulfate uptake efficiency. 

As with 98G, SO4 can also be blended with other fertilizers to maximize application efficiency. Oftentimes, SO4 is blended with a nitrogen source for sidedress application in the spring, and with phosphorus and potassium applications in the fall.

It should be noted that anytime SO4 or 98G are blended with other fertilizers, particularly those that attract moisture, the blend should go directly from the blending equipment to the spreader to minimize the amount of product degradation from added moisture. It is not recommended that liquid products be added to these blends because it can result in product breakdown and difficulty in the spreading operation.

Precision ag lime, seriously....

On Friday I was driving from Fort Dodge to Gilmore City, I thought there was a combine fire. Fortuneatly it was only a precision ag lime application, if there is such a thing. Friday was a relatively calm day, winds were less than 5 mph. You wouldn't expect much drift, but did you know that up to 1/4 of the lime you apply can drift off the field? Below are some of the pictures of a precision ag lime spread. 

 2 miles away I could get a picture of the ag lime cloud
This is precision application of ag lime
 When will the lime hit the ground? Better yet, where will it land?
 I wasn't aware ag lime applicators spread 120' patterns....
 Whoa, now they are speading a 480' swath! Talk about efficient!
 Since this is likely a grid sampled field, how to you control where the lime goes? Note the cool dust devil in the upper left corner, visable from the ag lime dust!
 Looks like most of the lime is landing on the next grid over, do you think this operator will still apply lime to that grid? How does he compensate for the drift?
 I have a feeling he doesn't like me photographing his work...
 
 No, I am sure he doesn't want me taking pictures!!
 There goes the product the farmer paid for!!

Too early to apply?

WOW, what a treat! Most of America is enjoying a very warm, early spring! I know everyone is itching to get outdoors and kick off the season. While it is still too early in most parts north of the Mason-Dixon line to begin your early spring fertilizations, it is never too early to begin spreading SuperCal SO4.

SuperCal SO4

One of the great characteristics of organic, all-natural products is not having to depend on mother nature for an application schedule. Take our SuperCal SO4, for example. It is a naturally mined, organic material that works beautifully with any fertility program. You can apply it any time throughout the year. You don’t have to wait for the frost to be out of the ground, you don’t have to wait for the ground temperature to hit a magical degree in order for the product to work. Our SuperCal SO4 can be applied, left alone and forgotten. As soon as the spring thaw begins or that first April shower (March this year?) hits, the SuperCal SO4 pellet will melt and the calcium and sulfur will begin to work.

Another benefit of SuperCal SO4 being a safe, all natural organic product is that it will not burn or damage your turf no matter how much you apply or when you apply. If you are working to create the best soil structure possible for growing the best turf of the season, now is the time to apply SuperCal SO4.
