With warmer-than-usual fall weather continuing to linger, Manitoba has extended the deadline for applying nutrients to farmland until Nov. 22.
This means nutrients can be applied until midnight, Nov. 21, as soil temperatures have not yet reached the freezing point.
Restrictions are designed to ensure nutrients are not applied when the ground is frozen and to protect the water quality of Manitoba’s lakes and rivers by reducing nutrient loading to waterways.
At this time, nutrient application is allowed but certain conditions must be met:
- nutrients can only be surface applied if they are immediately incorporated; and
- nutrients should not be applied in instances where the weather outlook is unfavourable, such as if snow or an appreciable amount of rainfall is expected that would result in run-off.
Without a variance, the standard ban on winter nutrient application begins Nov. 10 and ends at midnight on April 10.
Decisions about variations are based on actual soil temperatures, the presence of snow cover and the long-term weather forecast. When a variance is authorized, it applies to forms of nutrients such as livestock manure and inorganic fertilizer.
Additional information on winter spreading restrictions and the conditions necessary for a variance are online at the Manitoba Agriculture website.
