Lack of rain and high temperatures weather mean growers should put soil conditions at the forefront of decision-making this autumn, says Dick Neale, technical manager at crop production specialists Hutchinsons.
Mr Neale made the comments to farmers attending a recent demonstration day held in partnership with Sumo and Wilfred Scruton at HS Thirsk & Son of Little Grange Farm, Pocklington, Yorkshire.
Soil health
Decisions around cultivations need to be more strategic than routine, he said. “Let soil condition, not the calendar, dictate operations. Careful assessment this autumn could save unnecessary costs while safeguarding the long-term health of soils.”
“The first consideration is whether to work the soil at all,” advised Mr Neale. “Be patient – consider leaving soil re-structuring to nature rather than reaching for a big bit of metal.”
Minimal intervention, he suggested, is often best. Where cultivations are required, the seedbed need not be more than a couple of inches deep. “Ask yourself whether working deeper than that will really have an impact.
Growers should also weigh up the costs, said Mr Neale. A full-depth cultivation may cost around £90/ha, yet a targeted low disturbance loosening pass at £30/ha could achieve a better result.
Tramlines
Another key point was tramline management. Mr Neale argued for retaining them across multiple seasons. In many instances there is no point in removing them, he told listeners.
“They provide valuable access year-round. With GPS and matched-width machinery it’s easy to re-use the same lines. Removing them risks over-working the entire field, raising unweathered soil, creating clods, and leaving zones prone to re-compaction.”
Healthy soils between tramlines may not have been trafficked for years, allowing root networks, fissures, and earthworms to build strong natural structure.
While an over-aggressive pass risks undoing years of natural soil development, an under-aggressive pass can be just as damaging. “Failing to address compaction properly still costs as much as doing it right — but without the benefit.”
Cultivation
Farmers on lighter soils also need to tread carefully. “Over time, such soils may acidify in the upper profile, creating the need for occasional deeper cultivation.
This can help mix more alkaline subsoil into the top layer, reducing acidity in a way that may be more sustainable than repeated lime applications. Beyond mechanical options, cover crops offer another route to improved soil condition.
“Deep-rooting species such as brassicas, linseed, vetch, lucerne, chicory, and plantain can help break through compaction layers and redistribute nutrients vertically, however, identified compaction zones should be addressed with appropriate cultivation rather than rely on roots alone “
“Establishment need not be costly, with 10–12 kg/ha of seed often sufficient to protect soil, improve infiltration, and maintain biological activity over winter.”
