Managing grazing on different soil types

Wet weather affects fields differently. Soil texture, structure, drainage, organic matter, slope and previous management all affect how well land can withstand livestock traffic. Find out how to adapt grazing management to your soil type.

Heavy clay soils are generally more vulnerable to compaction and poaching when wet, while lighter sandy soils tend to drain more freely and are often less susceptible to compaction.

However, lighter soils can still suffer damage where drainage is poor, soil structure is weak or livestock repeatedly use the same routes.

Understanding how individual fields behave during wet weather can help you prioritise grazing, protect vulnerable areas and make better use of available grass.

Heavy clay and clay loam soils can hold substantial quantities of water.

When saturated, they may have limited capacity to support livestock without deformation, particularly under heavier cattle.

• Deep hoof prints and surface poaching
• Compaction that restricts root growth and water movement
• Reduced sward density and increased weed establishment
• Damage around gateways, troughs and feeding areas
• Increased run-off where the soil surface becomes damaged

• Graze these fields when conditions are relatively dry rather than relying on them during prolonged wet periods
• Remove livestock early when soil begins to deform underfoot
• Use on–off grazing where conditions allow limited access without significant damage
• Back fence previously grazed areas and avoid unnecessary walking
• Provide alternative access points and protect gateways
• Keep vulnerable areas, including wet corners and field margins, out of the grazing rotation when necessary

If heavy land becomes saturated, moving stock to a suitable, better-drained field, or housing them, may be preferable to continuing to graze.

Sandy and other lighter-textured soils generally allow water to drain more readily.

This can extend the period when grazing is possible compared with poorly drained clay soils.

However, lighter soils should not automatically be considered safe in wet conditions.

Compaction can still occur, especially where soil structure has deteriorated, a compacted layer restricts drainage or livestock concentrate around water and feed.

• Localised compaction around gateways and troughs
• Damage to poorly drained or compacted areas within otherwise free-draining fields
• Sward damage caused by repeated grazing or excessive stocking pressure
• Nutrient and soil loss where bare ground, slopes and run-off pathways coincide

• Assess actual soil condition rather than relying on soil type alone
• Use fields with good drainage and sound structure when conditions are suitable
• Maintain ground cover and avoid overgrazing
• Rotate livestock and manage gateways to prevent localised damage
• Monitor rainfall and adjust the grazing plan before conditions deteriorate

A lighter soil may offer more flexibility during wet weather, but continued grazing should still depend on the condition of the field and the forecast.

When conditions allow, dig a small soil pit in representative areas to examine the soil profile.

Look for restricted rooting, dense layers, poor aggregation, smearing and signs of waterlogging.

After a wet period, assess whether damaged areas are recovering naturally before deciding on remedial action. Avoid trafficking or mechanically loosening wet soils, as this can compound damage.

Where compaction persists, identify its cause before choosing an intervention. Improving drainage, managing livestock traffic and restoring ground cover may be as important as any mechanical treatment.
