Mulching speeds up crop decomposition and adds organic matter back to your soil

In Farming Simulator 25, mulching is a soil management step that breaks down crop residue—the stalks, leaves, and plant material left in a field after harvest. When you mulch, you're chopping that residue into smaller pieces and mixing it into the top layer of soil. This process happens faster than letting residue decompose on its own, and it returns nutrients to the ground instead of leaving dead plant material sitting on the surface.

Mulching is not required to farm successfully in FS25, but it affects how quickly your soil recovers fertility and how your fields look visually. If you leave a field unharvested or unworked after cutting crops, the residue will eventually break down naturally—but mulching speeds that up significantly. The main reason to mulch is soil health: fields with better organic matter content produce higher yields over time.

Key Takeaways

  • Mulching breaks down crop residue into the soil, which restores fertility faster than leaving residue to decompose naturally.
  • You need a mulcher attachment or a dedicated mulching machine to perform this task—you cannot mulch with a standard harvester.
  • Mulching works on fields that have visible crop residue after harvest, and the process takes time proportional to field size.
  • Fields with higher organic matter from regular mulching will produce better crop yields in future seasons.

How to mulch a field in FS25

To mulch, you need a machine equipped with a mulcher. The most common setup is a tractor with a mulcher attachment mounted on the rear. Some machines combine harvesting and mulching in one pass, but most of the time you'll mulch after harvest, once the field has visible residue.

Drive the mulcher over the field in straight passes, just as you would when mowing or plowing. The machine will chop the residue and work it into the soil. You'll see the field texture change as you work—the stubble and dead plant material will disappear, and the soil will look darker and more worked. The process consumes fuel and takes time based on field size, but there's no cost per hectare beyond the fuel.

Mulching is optional. If you skip it, the field will still produce crops next season, but the yield will be slightly lower than a field you've mulched regularly. Over multiple seasons, fields that are mulched consistently will outperform fields that are left untouched.

Mulching versus other soil preparation methods

FS25 offers several ways to manage soil and crop residue. Plowing turns over the soil completely and buries residue deep underground—it's more thorough than mulching but also more time-consuming and fuel-intensive. Cultivating loosens the soil without fully inverting it, and it also helps break down residue. Mulching sits between these two: it's faster than plowing but focuses specifically on breaking down surface residue and mixing it into the top layer.

If you want maximum soil health and don't mind the time investment, you can combine methods—plow once per season, then mulch between crops. If you're managing multiple large fields, mulching alone is usually enough to keep soil fertility steady without the extra time cost of plowing.

Machines that can mulch in FS25

Several tractor-mounted and self-propelled machines can perform mulching. Common options include the Krone EasyCollect and Krone EasyCut series, which can be configured with mulching attachments. Some forage harvesters also have mulching modes. The exact machines available depend on your game version and any mods you've installed.

When shopping for a mulcher, check the machine's specifications in the shop menu. Look for machines labeled as mulchers or machines with a mulching attachment option. Smaller machines work fine for small to medium fields, but larger operations benefit from wider mulchers that cover more ground per pass.

When mulching affects your yield

Mulching doesn't change the yield of the crop you're currently harvesting. Instead, it affects the fertility of the field, which determines the yield of the next crop you plant there. A field with high fertility (boosted by regular mulching) will produce a larger harvest than a field with low fertility.

You can see your field's fertility level in the field information panel. Fields start at a baseline fertility. Each time you mulch, you add organic matter and the fertility increases slightly. Over a full game year, a field you mulch regularly will have noticeably higher fertility than one you ignore. This compounds over multiple seasons—by year three or four, well-maintained fields produce significantly more than neglected ones.

Common mistakes when mulching

The most common mistake is mulching a field that has no residue. If you've already plowed or cultivated a field, there's nothing left to mulch, and the machine won't do anything. Always mulch right after harvest, when the residue is still visible on the surface.

Another mistake is forgetting to refuel. Mulching consumes fuel at a steady rate, and if your tank runs dry mid-field, you'll have to refuel and start again. Check your fuel gauge before you begin, especially on large fields. Finally, some players mulch obsessively, thinking more passes equal better results. One pass over a field is enough; additional passes won't increase fertility further and just waste fuel and time.

Frequently Asked Questions

Do I have to mulch to grow crops in FS25?

No. Crops will grow and produce yields without mulching. Mulching is a soil management choice that increases fertility over time, leading to better yields in future seasons. You can farm successfully by plowing alone, but mulching is an efficient way to maintain soil health.

Can I mulch while harvesting, or do I have to do it after?

Most machines harvest and mulch separately. Some forage harvesters can mulch during harvest in a single pass, but standard grain harvesters leave residue behind. Check your machine's description in the shop to see if it has a combined harvest-and-mulch mode.

How much does mulching improve yield?

The exact improvement varies, but fields with high fertility from regular mulching typically produce 10 to 20 percent more than fields with low fertility. The benefit builds over multiple seasons, so the longer you maintain a field, the more noticeable the difference becomes.

What happens if I mulch the same field twice in one season?

The second pass won't increase fertility further. Mulching once per season after harvest is the standard practice. Additional passes waste fuel without adding soil benefit.

Can I mulch fields I don't own?

No. You can only perform field work on fields you own or rent. Rented fields work the same way as owned fields for mulching purposes.
