High tunnel soils have unique nutrient management needs. Our team just published a new webpage that outlines best practices for soil testing, adding compost, determining nutrient needs, and selecting inputs for high tunnels in Minnesota.
Some key differences between high tunnel and field-based nutrient management include:
- Higher nitrogen and potassium needs for crops that produce higher yields in tunnels like tomatoes and cucumbers.
- High tunnel soils should be regularly tested for salts and nitrate. Soil nitrate should be factored into your nutrient needs.
- High tunnel irrigation water should be tested for nitrate, which should be factored into nutrient needs.
- In some cases, it may be appropriate to try to change the soil texture in a high tunnel, which is unrealistic in larger fields.
- Fertigation, or applying inputs through your irrigation system, is more common in high tunnels than in fields.
