Managing soil compaction for better crop growth during Ontario's planting season
Ontario’s spring planting faced challenges from soil compaction, impacting crops like corn, soybeans, and wheat. Despite some areas experiencing rapid planting under ideal conditions, other regions, even those with lighter soils, struggled due to excessive rainfall.
The team at OMAFA –on the fieldcropnews.com website, offering the following information about soil compaction.
Soil compaction occurs when heavy equipment is used on overly wet soils, crushing pore spaces and hindering water and air movement, which ultimately affects crop growth. While wet conditions in spring made planting difficult, the resulting compaction is now evident as crops such as corn are showing signs of stress due to heat and lack of moisture.
Farmers are encouraged to evaluate their fields for signs of compaction. Look for straight lines of stunted crop growth, often where implements have driven across the field. The next step is to diagnose the compaction depth using tools like a tile probe or a shovel. These tools can help detect compacted layers in the soil, which will be harder to penetrate compared to non-compacted areas.
When dealing with compaction, it is vital to focus on the affected areas. Tillage, applied carefully to the depth of the compaction, can help alleviate the problem. However, it is crucial to avoid tilling when soils are wet, as this can cause further damage.
Of course, long-term solutions include crop rotations and less invasive tillage practices.
By focusing on soil health and careful management, the team at OMAFA says farmers can reduce the impacts of compaction, ensuring better yields for future seasons.
