MINNEAPOLIS/ST. PAUL (04/19/2022) — As Minnesota farmers prepare to head into their fields and begin planting crops this spring, many are hoping to avoid the high temperatures and moisture deficits that resulted in drought conditions for much of the state last year.
According to the recently released U.S. Seasonal Drought Outlook map from the Climate Prediction Center, there is an equal chance of below normal, near normal and above normal precipitation through at least June of this year.
Jeffrey Strock, a professor at the Southwest Research and Outreach Center, provides expert comment on what these possibilities mean for local farmers this planting season.

“Local data suggests that precipitation last fall and recent rains, snow and gradual melting have helped replenish soil moisture near the surface, but additional precipitation is needed to recharge depleted moisture deeper in the soil profile.
Precipitation is highly variable and unpredictable. If dry conditions persist, it is important to conserve as much pre-plant soil moisture as possible. Reducing the number of tillage operations that turn moist soil to the top of the ground will help reduce moisture losses.
Maintaining crop residue at or near the soil surface for as long as possible will save moisture and reduce erosion. Cover crops can increase water infiltration rates and water storage capacity. Overwintering cover crops will use water as they put on new growth in the spring and can negatively affect the following cash crop if not managed well.
If air temperatures and soils warm up quickly and moderately dry conditions continue, farmers may be able to get planting done quickly. If dry conditions persist after planting, crop root systems will grow relatively deep into the ground in search of moisture. If timely rainfalls occur during the growing season, farmers could expect average to above-average yields. If conditions remain cool and planting is delayed, coupled with extended dry conditions, farmers could expect below average yields.”
