What comes to mind when you think of harvest 2018? For me it was the most challenging harvest season since I started farming in 2006. A wild ride that went from one extreme to another, which made harvest and any fall work very challenging. From down corn to bean pod shatter and just about any weather event you could imagine, except for dry and seasonal. This forced me to go back to the drawing board. I brushed up on best management practices from agronomists and universities and made a plan.

Using this plan, I believe I minimized as many negative factors as I could. I and probably you too had several plans that I did not execute, or accomplish all tasks on the list. I continued to get wet, snow, and cold conditions that are not conducive to being in the field for any reason until the ground froze.

Managing negative side effects and limiting potential damages

As this fall unraveled and weather conditions continued to go from bad to worse, I stopped and thought about how I should deal with the side effects of harvesting and performing other tasks. A quote from Jim Collins came to mind, “Bad decisions made with good intentions, are still bad decisions.” 

I had good intentions to complete several tasks this fall, but it would have been a bad decision if I moved forward because the field conditions were not right. I chose to leave the ruts in the field and approach them in the spring. The soil was and still is too wet to do any good by leveling them out.

Paul Jasa, Nebraska Extension engineer had an article that talks a little about fall tracks. Here is an excerpt: “The first impulse may be to do deep tillage to rip out that compaction to be able to plant in spring. However, the combine ruts themselves are going to compact 2 to 3 feet into the soil. Any surface tillage will fill in the ruts so your planter can cross them, but it won't fix compaction. With compaction that deep, its wetter down deep, and you can't break compaction on wet soil. You're going to have to live with it the next season, so it’s best to minimize what you're creating this fall.”

Now is a great time to evaluate your soil conditions and make a plan for spring soil management

Does spring tillage work for you?

Spring tillage is one tool in your toolbox that might be used for the following:

When you think about spring tillage what comes to mind. A cultivator? A soil finisher? Or a vertical till machine?  A solution that not everyone thinks about is the Kinze Mach Till.

The Kinze Mach Till can be utilized not only in the fall, but also in the spring to get exceptional seedbed preparation. Customers and dealers instantly see the value it has in the fall, but are uncertain about using it in the spring. 

Consider the following examples:

Say you currently utilize a 45' cultivator. It weighs roughly 23,000 lbs. At 7 mph it covers roughly 30 acres/hr. and you need around a 400 HP tractor to pull it. The cultivator only gets utilized during the spring.

Now compare that to a 26' Mach Till. It has the same weight at 23,000 lbs. At 13 MPH covers roughly 48 acres per hr. and you can pull it with the same 400 HP tractor. Not only can it be utilized for fall field work, but also spring, this gives you additional return on your investment.

How do I minimize compaction with spring tillage?

A question high on your list might be, “What about compaction?”  

It is important to keep in mind, both machines have the potential to cause compaction if you work your soils too wet.

The Kinze Mach Till is a hybrid horizontal tillage tool that combines the benefits of vertical tillage, conventional tillage and soil finishing tools into one versatile machine.

The Mach Till cuts and throws the soil at an angle to avoid creating a smear or compaction layer in the soil, and then mixes the soil and residue together. The corrugated rubber roller on the back of the machine sheds soil, and breaks up larger clods, while gliding through the field.

Is the weight of your cultivator spread out to decrease the PSI felt by the soil?

This hybrid has taken it into account - it has an extremely wide tire footprint for maximum flotation. The shape of the contact area is specially designed to minimize the impact on soil structure. Adding to the flotation is the rear furrow roller; specifically further spreading out the PSI felt by the soil.

Mach Till Up Down Arrows

Kinze, as well as customers, have tested Mach Till in spring conditions, and have had great results.

As I mentioned earlier caution is necessary when using tillage to dry the soil's surface because tillage can result in compacted subsurface soil layers. It can be tempting to jump the gun and not wait long enough for the soil to dry.

The greatest probability for causing soil compaction takes place a couple of days before the soil is dry. Iowa State University Extension soil management specialist Mahdi Al-Kaisi has a few easy checks to help you determine if it is dry enough, “Be careful not to enter the field if the drainage tiles are still running, which means the soil is above field capacity. You need to inspect the field and make sure that soil moisture is at or below field capacity by the simple test of taking a handful of soil and squeezing it in your palm; if you notice a trace of moisture on your palm, it is too wet to enter the field."

I am sure after hearing this advice you are concerned about having enough time to cover your acres before planting. Not to worry the Mach Till has you covered.

Spring is a sprint; the Mach Till can cover ground quickly after the soil is fit and stay in front of your planter to optimize planting windows.

Have you considered the other agronomic benefits designed into Mach Till?

The Mach Till combines the benefits of many tillage tools into one product that that makes it multipurpose, covering acres at high speed, provides uniform residue management, and a planter-ready soil finish.

Does your current spring tool have all these benefits working for you? Remember tillage is a tool in the toolbox; don’t take your soil for granted!
