Nutrient Removal as a Function of Corn Stover Cutting Height and Cob Harvest

Sustainability of Corn Stover Harvest for Biomass

Comparison of wet and dry corn stover harvest and storage

Corn stover has great potential as a biomass feedstock, but harvest and storage of this material is challenged by weather conditions at harvest; material moisture; and equipment shortcomings. Field drying characteristics, harvest efficiency and rate, product bulk density, and storage characteristics were quantified for stover harvested and stored in wet or dry form. Only in one case did stover ...

Single - Pass , Split - Stream Harvest of Corn Grain and Stover

A grain combine was equipped with a whole-plant corn head and modified to produce single-pass, whole-plant corn harvesting with two crop streams: grain and stover. Capture of potential stover DM varied from 48% to 89% for leaves, from 49% to 92% for stalks, and was greater than 90% for husks and cobs, depending on corn head height. Stover aggregate moisture varied between 36% and 50% (w.b.), an...

Production costs of potential corn stover harvest and storage systems

Corn stover has potential as a bioenergy feedstock in North America. We simulated production costs for stover harvest (three-pass and two-pass with baling or chopping, and single-pass with baling or chopping) and on-farm storage (outdoor and indoor bales, outdoor wrapped bales, and chopped stover in bags, bunks, or piles). For threeand two-pass harvest, chopping was 33e45% more expensive than b...
