Harvesting corn is a matter of picking the ears at peak flavor. Good grain quality begins in the field. Harvesting corn silage at moistures that are too low will result in poor packing, inadequate air exclusion, poor fermentation and heating. They are not dwarf corn plants. Soybeans also are a major grain crop in Delmarva, though not all of the harvest is used to feed livestock, including chickens, pigs, dairy cows or cattle.
Like many of the area farmers, he has a corn-soybean rotation and farms on Clarion-Nicollet-Webster soil. Harvesting too dry (high DM content) promotes mould development because the silage cannot be adequately packed to exclude oxygen. When harvested at optimum maturity, sweet corn silks are brown and dry; the kernels are plump, sweet, milky, tender and almost maximum size.
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.
Depending on the length of time these packages will need to be stored, stover moisture content may need to be 20 % or less. This may mean you only harvest one way and carry a dead head across the field, but if you can save yield it can be worth the time, effort and fuel.
High-moisture Ear Corn or Corn and Cob Meal: This refers to corn grain and cob material that is harvested with a combine set to return the grain and a portion of the ground cob to the hopper. This is attributed to the reduced starch digestibility of hard-textured, dry kernels in newly fermented, unprocessed corn silage.
Ready-grown plants will establish quickly and provide cobs earlier than sowing seed directly into the soil. Grain moisture content showed a decrease from the Oct. That's why the long, crisp, sunny days of early fall produce the sweetest corn. This information combined with average whole plant dry-down rates can be used to roughly predict the How To Harvest Corn proper time to harvest corn silage.
Early harvest of corn can cause another set of issues because of hot and dry conditions. We estimate that the average harvest window to shred, windrow, and bale corn stover will be 40 days after corn grain harvest, after which weather and soil conditions are often not conducive to field traffic and stover harvest.
Ready-grown plants can go into the soil from May. Corn plants severely stressed by dry weather without cobs do not have kernel milk-lines to use as estimates, but plants are typically much higher moisture than they appear. In summary, there is little you can do now to effect corn grain drying rate in the field.
Unless you plan on eating them right away, store the ears of corn in a refrigerator, leaving the husks on. They will keep for almost a week. When pricing earlage relative to dry corn grain, one must account for the amount of corn in the earlage, assign some value to the roughage in the earlage and adjust for moisture content.
Harvesting too dry also results in lower digestibility, protein, and vitamins A and E. So harvesting corn at the proper dry matter content will result in better animal performance and lower feed costs. Plunkett has farmed for 25 years and established his custom harvesting business in 2012 as a result of the DuPont program.
