How Farms Work for Dummies



The relationship of corn silage harvest moisture and maturity to its quality and performance is often underestimated. The energy content of earlage varies with harvest method and the amount of roughage ensiled with the grain (Table 1). Harvest methods that collect a larger proportion of stalk (for example, all-crop headers) will produce a lower-energy earlage product than harvest methods that only ensile grain and a portion of the cob.

Therefore, if the prices of new crop corn and soybeans remain around those levels, it is likely that farmers will plant more soybeans during the 2017 planting season and this could put some upside pressure on corn prices while putting downside pressure on soybean prices because of the behavior of agricultural producers.

Low-moisture corn silage that is not harvested using a kernel processor can be lower in starch digestibility. Once the kernels are in the grain tank all the material left behind must be dealt with. For a detailed assessment of on-farm moisture measurement techniques based on studies conducted by the UW Soil & Forage Analysis Lab at Marshfield, Wisconsin, refer to On-Farm Moisture Testing of Corn Silage ” by John Peters.

A Purdue study proved that yield losses of 0.6 percent-1.6 percent per point of moisture can occur in corn drying in the field(1). Poor kernel development can be the result of poor pollination, too few plants resulting in poor pollination, overcrowding, or a potassium deficiency in the soil.

Farmers in the Thumb and the rest of the state are at the midway point of the fall harvest, with much of the soybean crop off the field and corn just starting. At maturity the kernels of some varieties are easily shelled by a light touch to the ear. First, look at the top ear on your corn plant.

The earliest known ears of corn were tiny - only a few inches long. Harvesting grain at too high of moisture can result in severe kernel damage during threshing and drying. The plants of gourdseed corn are heavily stalked and bear ears having a large number of rows of thin, deep kernels.

There are standard varieties, sugar-enhanced hybrids that give producers a three-day harvest period and demand soil temperatures about 10 degrees warmer than usual sweet corns, and the super-sweet, which is the trickiest of all to produce. Some ear characteristics, including husk senescence timing, husk coverage, husk tightness, and kernel characteristics may influence hybrid drying rate, but are generally are less important than weather conditions.

Inside the combine a machine seperates the husks, kernels, and cob. Crop profile for sweet corn in Florida. Each stalk of corn will produces one or perhaps two harvestable ears of corn. Here's a great sweet corn harvest video. Spacing that is too narrow will lead to higher than normal leaves and stalks, which makes it harder for the combine to separate the grain from the trash.

Finally, consider a "worst case" scenario at the same yield and price levels where excess harvest losses are 15% and down corn is as high as 30 percent moisture, the cost of harvest losses would be $123.75 per acre but only $79.37 would be needed to dry the crop, so even at this high moisture the savings would be $44.38 per acre.

Start by harvesting ears where silk appears that day. When planning harvesting operations, keep in mind How To Make Corn the length of time required to harvest the field. Corn is harvested at a Georgetown farm. He spends 10 hours a day there this time of year, harvesting thousands of pounds of corn across hundreds of acres, all while taking business calls over the cab's speakers.
