Field Loss Calculator

spaced@hort.wisc.edu — Mon, 02 Nov 2009 14:05:52 GMT

This MS Excel spreadsheet allows producers to calculate the influence of harvesting today versus allowing the crop to stand in the field and harvesting later. It accounts for higher drying costs versus grain losses during field drying. It allows the user to account for elevator discounts and grain shrink.

Calculating Grain Weight Shrinkage in Corn Due to Mechanical Drying

spaced@hort.wisc.edu — Mon, 02 Nov 2009 13:52:44 GMT

Following harvest, a corn grower must usually decide whether to sell wet corn "as is" at a mositure discounted market price or mechanically dry the grain (on-farm or by custom drying) al a total cost the grower hopes is less than the moisture discount. One of the expenses involved in mechanically drying grain is the "cost" of the weight loss that occurs during the drying process. This weight loss by drying is referred to as "shrink" and is expressed as a percentage of the original quantity before it is dried. Growers must calculate shrinkage in order to accurately determine the total cost of mechanical drying. (For more information on determining the profitability of on·farm drying see NCH-21 "Economics of On· Farm Corn Drying. ")

Considerations for Artificial Drying of Soybeans

spaced@hort.wisc.edu — Mon, 02 Nov 2009 13:49:31 GMT

This fall’s weather may create situations where some growers will be tempted to artificially dry their soybeans. It is not a good situation when growers need to consider artificial drying of soybeans. It presents several challenges in order to keep the soybeans at an acceptable quality level to avoid dockage. Growers will have to weigh the advantages and disadvantages for their own operation to determine what is best for their situation.

Renewed interest in snaplage displayed

spaced@hort.wisc.edu — Mon, 02 Nov 2009 13:42:37 GMT

It is my impression that there was a resurgence of interest among dairy producers and nutritionists in harvesting high-moisture corn as snaplage this past fall. This is partly due to snaplage being heavily promoted by custom cutters who were eager to secure more business for their forage harvesting crews and partly due to the increasing cost of harvesting with a combine and processing at the bunker. Recent studies have also confirmed that if harvested at the proper kernel moisture, snaplage can have an extremely high feeding value if harvested, processed and stored correctly.

Adding Organic Acids to High Moisture Corn

spaced@hort.wisc.edu — Mon, 02 Nov 2009 13:31:58 GMT

In situations where fermentation of high moisture corn (HMC) is in jeopardy, treatment with organic acids can prevent heating and mold growth. Organic acids can also be used to preserve HMC when adequate storage space is not available. Animals fed HMC treated with organic acids perform similar to animals fed untreated HMC.

Weigh Risk of Leaving Corn Stand Through Winter

spaced@hort.wisc.edu — Mon, 02 Nov 2009 13:17:10 GMT

The October 26, 2009 Wisconsin Crop Progress Report from the Wisconsin Field Office of the National Agriculture Statistics Service stated only 9% of the Wisconsin corn crop has been harvested, far less than the 5-year average of 37%. Moisture spot checks are indicating very wet grain with unfavorable drying weather in the near-term forecast. Even if grain moisture was dry enough for harvest, saturated soils will likely cause further delays. This situation has caused some corn growers to consider leaving corn stand in the field until spring.

2009-2010 Dairy Cattle Feeding Issues with High-Moisture Corn, Snaplage and Dry Shelled Corn

spaced@hort.wisc.edu — Mon, 02 Nov 2009 13:09:08 GMT

Cooler than normal summer growing conditions coupled with a killing frost in early October is causing high-moisture (HM) and dry corn to be harvested at higher than normal moisture contents. Dairy cattle feeding issues that may arise during feed-out of wet HM corn include: reduced starch content, fast rate and high extent of ruminal starch digestion, and mold/mycotoxins. Some of these same issues may also arise with feeding corn harvested for dry shelled corn that had been exposed to a killing frost prior to reaching physiological maturity.

Combine Considerations for a Wet Corn Harvest

spaced@hort.wisc.edu — Wed, 28 Oct 2009 17:07:25 GMT

Adjusted properly, your combine can handle corn between 20 and 30% moisture. However, as moistures exceed 30%, your work will be a balancing act between leaving unthreshed grain in the field and grain damage. Here are a few tips to help guide you along in this wet harvest season.

Understanding Corn Test Weight

spaced@hort.wisc.edu — Wed, 28 Oct 2009 12:27:38 GMT

Corn test weight (TW) is an often discussed topic of conversation among corn growers. The topic moves to the forefront in years when corn has been stressed at some point during the grain filling period or when the growing season is ended by frost before physiological maturity is reached. In many cases, the concept of test weight is misunderstood.

High Moisture Corn Harvest and Storage Considerations

spaced@hort.wisc.edu — Wed, 28 Oct 2009 12:13:28 GMT

Even the best plans to ensile high moisture corn at the proper moisture level are sometimes thwarted by weather and time constraints. These types of situations prompt the question, "What can I get away with?" Here are some factors and suggestions to consider when making decisions regarding the harvest and storage of high moisture corn.

Hail Damaged Corn – Risk of Molds and Mycotoxins?

spaced@hort.wisc.edu — Thu, 03 Sep 2009 18:02:30 GMT

In late July, there was a significant hail event in Wisconsin, primarily located in the southwestern portion of the state (Fig. 1). At that time, the corn crop was at approximately the R1 (silking) growth stage, but ranging from pre-VT (pre-tasseling) to R1. The hail event led to extensive bruising on the ear, husks, and stalks, however, the severity of the hail event varied from field to field. While some fields had finished pollinating, with bruising on ears, others had not yet started the pollination process and ears were unaffected.
