Rye planted in central Ohio by Nov. 1 still has time to establish this year, even after weeks of exceptional rain delayed silage corn harvest and left fields rutted across much of the state. The optimal window for small-grain forage planting is only just beginning, and earlier planting of winter annuals does not carry the yield premium growers expect from spring-planted crops.

Very few producers in rain-hit areas of Ohio got silage corn off before the latest round of storms, and upcoming harvests will likely run on wetter-than-optimal soils, according to an advisory on fall field operations from Farm and Dairy. The focus now shifts to establishing small-grain forage on ground that took a beating.

When do ruts actually need fixing?

On research fields this year, ruts that would normally crust over and cause longer-term issues have leveled out more than expected thanks to the continuous rain. The rule of thumb: seed spacing is rarely a concern as long as ruts are shallower than 2 inches at planting. Older drills are more sensitive, and struggle with ruts deeper than 1 inch.

Rut depth, weather between harvest and planting, and equipment sensitivity together determine whether repair work is needed before drilling small grains this fall.

How should growers repair ruts?

Wait until the upper 2-4 inches of soil are dry enough to work. The simplest test: if the ground is too wet for a closing wheel to effectively close a seed furrow, it is too wet for tillage.

• Make multiple shallow passes rather than one deep tillage pass or full soil inversion.
• Shallow passes move material laterally along the surface and level it better.
• Deeper passes risk pulling moist soil from lower layers into the worked zone.
• Pockets of surface moisture raise compaction risk on the next pass.

What about deeper compaction?

Rutting is the visible problem in wet years, but deeper compaction remains a perennial challenge for forage producers. Field entrances and travel paths suffer worst, especially in a silage corn-small grain baleage rotation.

Growers can spot compaction before silage harvest wraps up by looking for shorter plants, horizontal root development and harder soils. A survey flag pushed into the soil identifies zones of increased resistance. Where deeper tillage is warranted, aim to till at least one inch below the compacted layer, concentrating on areas with frequent machinery traffic rather than working the whole field — saving both time and diesel in a hectic season.

If soils do not dry enough for deep tillage this fall, yield losses are unlikely to be severe. Deeper compaction affects winter crops less than summer crops in most years, particularly with a lodging-resistant variety in the ground.

Till or not till before small grains?

The biggest question from growers who do not normally till before small grains is whether an improved seedbed justifies planting later. There is no clear-cut answer, especially when gaps between rainfall events are short.

Timings matter more:

• Hessian Fly Free date: do not plant before it — the last week of September for northern Ohio, up to Oct. 5 for southern Ohio.
• Wheat and barley: ideal in the first two weeks after the fly-free date.
• Triticale: can continue for an additional two weeks beyond that.
• Rye: target Nov. 1 in central Ohio, earlier where snow comes early or further north.
• Seeding rate: boost by 15-20% for later-planted small grains.

The advisory's bottom line is straightforward: most areas of Ohio and surrounding regions still have time to plant this year and to address the soil management problems this season's rain has left behind.
