Pine & Isanti County Ext. Update

September 2026
From Your ANR Extension Educator
School is back in session and harvest is underway in the fields and gardens, so flower gardens may be forgotten about. As Extension Educator, Robin Trott says:
"Fall is often seen as the garden’s winding-down season, but it’s a critical window for pollinators. Bees, butterflies, and other beneficial insects need late nectar sources to survive migration or overwintering. By planting fall-blooming perennials and designing pollinator-friendly containers, we extend the garden’s generosity right up until frost.
In Minnesota, fall is not the end of the garden; it’s a chapter filled with color, purpose, and pollinator support."
There is still time to plant perennials this fall! If you want to attract pollinators consider incorporating asters, goldenrod, or rudbeckia (black-eyed Susan) into your flower gardens. Perhaps you want to do something a bit smaller or in a container? Try native asters like Aromatic or Wood's Blue, pansies and violas, or salvias and sweet alyssum, which are pollinator friendly too.

University Resources Made For You
Hardy Mums
Shorter days and cooler nights signal that autumn is right around the corner. Colors shift not only in our trees, but across our gardens. Chrysanthemums, those bright, cheerful fall bloomers, are suddenly everywhere. The mums stacked outside big-box stores and grocery stores are annual florist mums: great for porch pots but not bred to survive a Minnesota winter. University of Minnesota researchers have been breeding northern-hardy perennial mums since 1977. These mums are selected for winter survival (reliably hardy in Zones 3-9), strong branching, and dependable blooms.
Precision Drainage
Using technology and automation to target the use of inputs like fertilizer or irrigation can save costs, boost productivity, and minimize environmental impacts. That’s what is offered by precision agriculture, which has permeated nearly all parts of crop production except, until recently, drainage. Learn more about Extension’s Minnesota Drainage Program.

Japanese Beetle Survey
The University of Minnesota is developing a research proposal focused on Japanese beetle management and the winsome fly. The proposed research will examine whether insecticide products or application timing can be adjusted to reduce harm to winsome fly while maintaining practical Japanese beetle control.
The University of Minnesota is developing a research proposal focused on Japanese beetle management and the winsome fly. The proposed research will examine whether insecticide products or application timing can be adjusted to reduce harm to winsome fly while maintaining practical Japanese beetle control.
We want to make sure the research will be helpful for Minnesota fruit and vegetable growers. Help us make sure the research captures your growing system and management practices by filling out our survey, Japanese Beetle Management Practices and Decision-Making in Minnesota. The survey is anonymous, works on mobile, and should take 3-4 minutes.
Harvesting Drought Stressed Corn
During drought conditions, aside from areas where plants are barren (with no pollination or ear development) and have little green tissue remaining, it is often best to delay corn silage harvest as long as possible to allow for maximum development of the kernels and total dry matter.
Harvest Moisture
Test the moisture level of corn silage before and during chopping. Silage moisture is a crucial factor in the ensiling process, and the moisture content of drought-stressed corn can be misleading. Even if the corn looks fired up and dried out, it may still contain over 70% moisture.
When testing for moisture, it’s essential to get a representative sample from the field. A Koster tester or microwave oven can provide an accurate estimate of the moisture level of the silage. Test often because silage that is too wet or too dry will have storage issues.
- Silage chopped too wet can become clostridial, and nutrients can seep from storage structures.
- Silage that is too dry will not pack well, increasing the potential for air pockets, mold, and storage losses.
- It is possible to add moisture to dry corn silage, but it is usually not feasible, as it takes large amounts of water to increase moisture. For example, it takes 7 gallons of water per 1 ton of silage to raise the moisture level by 1%.
The recommended moisture levels for the different storage options of corn silage are:
- 65-70% for bunkers
- 60-70% for bags
- 60-65% for upright stave silos
- 55-60% for upright oxygen-limiting silos
- 40-55% for baleage
Test for Nitrates
Nitrates taken up by plants are normally incorporated into amino acids, the building blocks of proteins. The conversion of nitrates to amino acids usually occurs in green leaf tissue. Drought conditions can cause nitrates to accumulate, especially in the lower one-third of the stalk.
Nitrate concentrations in drought-stressed corn:
- Leaves: 64 ppm nitrate-nitrogen
- Ears: 17 ppm nitrate-nitrogen
- Upper third of stalk: 153 ppm nitrate-nitrogen
- Middle third of stalk: 803 ppm nitrate-nitrogen
- Lower third of stalk: 5524 ppm nitrate-nitrogen
- Whole plant: 978 ppm nitrate-nitrogen
Raising the cutting deck to a height of 10 to 12 inches to avoid the stalks that are highest in nitrates will decrease the nitrates in the silage, but also decrease tonnage. The whole-plant nitrate concentration should be factored into the decision regarding cutting height.
Harvest should also be delayed a minimum of three days following a rainfall event, as a flush of nitrates can enter the plant, temporarily increasing nitrate concentrations.
If ensiled properly, one-third to one-half of the nitrates will be converted and released as a gas. Test the silage during feedout to ensure you’re not feeding unsafe nitrate levels, taking into account the nitrate level in the corn silage and the proportion of corn silage in the ration.
Green chopping drought-stressed corn is not recommended, as nitrates will likely be high without fermentation. Chopping length also plays a role in the ensiling process. The theoretical length of cut for processed corn silage is 3/4 inch, and if not processed, the length should be 1/4 to 1/2 inch.
If harvesting corn silage that is drier than recommended, decreasing the cutting size may help with packing.
Using an inoculant can also increase the chances of successful fermentation. With reduced yields, it is critical to preserve the forage we do have.
