These opportunities are meant to be a chance to get your silage, snaplage, or HMC samples tested in a relatively convenient manner. Also take advantage of other opportunities that you may have through your agronomist, nutritionist, or by conducting your own sampling and testing. If doing the testing on the farm, just make sure you take the time to either calibrate your methodology and to do the methods properly.

Collecting a Good Sample
Sample collection is very important to getting good test results. The first step to collecting a good sample is to think about all the different fields and/or varieties that you want tested. Each variety will mature and dry-down differently, and there are always differences from field to field, so plan on sampling most of the fields that you are thinking about ensiling this year.
When collecting the actual sample plants, collect your sample according to the variability in the field. If the field is pretty consistent, collect at least five plants in a W-shaped pattern from the area being sampled. If the field is variable, collect more plants and collect at least one or two from each size of plants found in the field. Wrap the plant stems in wet paper and bring all your separate samples to the collection site nearest you. If in doubt, collect a few more plants for each given sample, or collect more than one sample according to field variability, whether it be soil type, variety, or whatever else.

Lastly, collect them as soon as possible before you leave for the collection site. Call Scott’s cell phone at 715-923-0807 if you are running behind so that he can either wait for you or arrange a meeting point.

Storage considerations for corn silage
High-quality corn silage can be produced in many different types of storage structures. However, each structure
type – bunker silo, silage bag, upright silo, or silage pile – needs to have the corn silage at a certain range of whole-plant moisture to achieve the best possible results. The recommendation is to hit the following ranges:

Silo Type                                 Recommended Moisture %
Upright                                        60-65
Upright, oxygen-limiting           50-60
Horizontal silos                          65-70
Silage bags and piles                60-70

Packing Capacity – When packing silage into a bunker silo, you must have enough packing weight to adequately handle the forage coming into the bunker. If you do not pack adequately, you will lose dry matter and forage quality. A quick rule-of-thumb is that you need about 800 lbs of weight per delivered wet ton per hour. For example, 80 tons delivered per hour requires 64,000 lbs of packing capacity. Stated Simply: Pack or Lose! If you do not take the time to pack correctly, you will have lost 2 to 5 times as much silage to spoilage as you should. So do your best by:
1. Use the heaviest tractors you can. Total weight has shown to be more important than per tire weight.
2. Unload the silage in thinner layers. This will allow each layer to be more properly packed.
3. If feasible, slow down your delivery rates. The single most important variable to final silage density in a significant study a couple years ago was delivery rate. If the rate was less than 60 ton/hour, the final density was sufficient, if more than that, the density decreased.
4. Harvest at the right moisture for your system. See above.

Assistance with buying/selling corn silage/snaplage/HMC                                                                                                    There are always fields of corn that get sold from producer to producer. Make sure you work together to come up with a ‘good for both of you’ contract that spells all appropriate features out clearly. Scott Reuss can assist in yield estimations, valuation, contract wording, or however else you need assistance. Contact Scott Reuss at 715-732-7518 to tell him what you need and we will set times to get it done.
