Just like harvesting Sugarbeet and Potato, harvesting Corn involves the need to purchase a different type of tool or machine to complete the harvest. Hard to estimate, but surface organic matter levels would decrease and equilibrate to a lower level if corn stover were harvested frequently over a period of time. Combines are equipped to either spread the material evenly over the field or to drop a windrow of plant material that could be baled for livestock.
Extension agronomist Bob Nielsen says projected corn yields are already down due to various stresses, and harvesting wet may protect from further mechanical harvest losses. The ideal moisture content for popcorn is between 13 and 14%. Corn planted too closely will require more water and fertilizer and may offer a smaller yield.
The combine owners manual may contain instructions for setting the combine for the harvest of corn and cob meal. Geographic location, planting date, hybrid selection, and weather conditions affect the relationship between kernel milk-line position and whole plant dry matter content.
For example, the moisture content of stover when you harvest grain at 20 % moisture would be about 40 % moisture. The overall quality of the 2016 corn crop was better than the average of the previous five crop years (5YA¹) on most attributes, with 87.8% of the samples How To Harvest Corn Seed meeting the standards for U.S. No. 2 grade or better.
Harvesting corn as earlage provides a longer residue grazing window for cattle. Turning corn grown as feed into earlage requires no drying costs. If earlage is harvested while the corn is at less than optimum moisture content, it will not pack well, which will lead to excessive spoilage.
The approximate value of the nitrogen, phosphate, and potash per DRY ton of harvested corn stover is $2.72, $0.79, and $2.36 (based on $0.20, $0.22, and $0.12 per lb. of nitrogen, phosphate, and potash fertilizers), for total nutrient value of $5.87 per DRY ton.
Kernels and ears are the female flowers.) Kernels of sweet corn can be yellow, white, black, red, or a combination of colors. Sweet corn can be planted with a no-till planter in a minimally prepared bed with only secondary tillage, such as an S-tine cultivator, or in a previously tilled field without any tillage treatment.
Regardless of the harvest date, proper harvesting and storage are necessary to ensure that a good crop results in good feed. The only reliable method of determining the optimal time to harvest corn silage is to sample the crop and directly measure the % dry matter of whole plants.
At Leuer farm, based in Greenfield, they can combine 60 to 80 acres of corn a day. I plant 100% Golden Harvest corn. As the table clearly shows, high temperature drying followed by fast cooling can have a devastating effect on stress-cracking of corn kernels. Leave popcorn in the garden until the stalks and husks are brown and dry, then twist and snap each ear from the stalk.
However, the stover from such a plant would supply only about 33% of the energy while the ears would supply approximately 67% of the energy. Harvest the corn when the husks are entirely yellow or brown and completely dry. If it's clear, the kernels aren't quite ready.
