How to Prevent Soil Compaction: 3 Proven Strategies

Fixing or recovering from soil compaction can take years and prove costly to your operation. But as Albert Einstein once quipped, “Intellectuals solve problems, geniuses prevent them.”

While we can’t confirm Einstein was referring to soil compaction, we can confirm you don’t need to be the next Einstein to implement a genius-level soil management strategy with these four compaction prevention tactics.

Already dealing with soil compaction? Don’t worry, we won’t leave you high and dry. Learn four ways to help alleviate and manage existing soil compaction.

Effects of soil compaction in agriculture

Soil compaction affects crop emergence, root development and root disease susceptibility, eventually reducing yield potential. Long-term compaction disrupts soil structure, impairs water movement and increases runoff.

What are the causes of soil compaction?

Factors that create compacted soils typically include:

• Planting into soil that is too wet
• Any equipment traffic during the year or at harvest under wet soil conditions
• Planting too shallow
• Setting too much pressure on the planter gauge wheels and closing wheels

How to prevent soil compaction

It’s a gamble: Planting in wet soil can cause compaction, affecting germination and emergence and reducing yield potential. But staying out of the fields during wet, early-season conditions can also reduce yield potential by delaying planting.

Here’s how to get a jump on early-season planting with compaction prevention in mind.

Make sure machinery isn’t the culprit

Whether you’re rolling out on tracks or tires, heavy axle loads (over 10 tons) combined with wet soil conditions can create compaction down 12”. The pressure set on gauge wheels and closing wheels must not be too high, and lowering tire inflation pressure is key. Inflating to 20-30 psi will greatly help reduce soil compaction.¹

Understand when soils are too wet to plant

Test soil moisture by compacting a handful of soil and dropping from waist height. If the compacted soil ball doesn’t break apart upon impact, it’s too wet. If possible, it’s best to limit field activities when soil is wet.

How to reduce existing soil compaction

In an ideal world you would be able to prevent soil compaction before it occurs, but if your fields show the following symptoms, compaction is likely already present:

• Plants with stubby, twisted roots, or taproots growing horizontally
• Soil with drainage issues or standing water
• Physically dense and hard-to-dig soil regardless of moisture content
• Crops with stunted growth, discolored leaves or drought stress
  

Here are three practices to consider to start correcting compaction:

1. Reduce tillage and increase crop residue cover: These steps will increase soil aggregates and reduce compaction. Soil aggregates are key for soil to efficiently filter air and water, creating a porous structure for easy root growth.
2. Reduce excessive equipment passes: Consider traffic lane designs and/or GPS systems to manage traffic flow in the field.
3. Plant deep-rooted cover crops: Tillage radish or alfalfa are great rotational crops to break up compaction. Several years of alfalfa can result in roots up to 20'.²
4. Practice deep tillage or subsoiling for severe compaction: If your soil compaction is severe, consider deep tillage or subsoiling. To increase fracturing in the compacted zone, fields must be very dry (especially in high clay soils) as deep tillage in wet soil exacerbates compaction. To manage costs and labor, you can use deep tillage selectively in heavily trafficked areas of the field. However, these methods are a small bandage on a big wound; this doesn’t fix compaction long term. Preventive measures should always be paramount and can set your crops up for success.
   

Whether you’re preparing fields for planting or strategizing post-harvest soil management, reach out to your seed retailer, a nearby extension office agent or a professional like your regional BASF representative to create a soil management plan.
