  • Harvesting of Microalgae

    In commercial algae production harvesting is generally done by centrifugation. However, the costs and energy demands for harvesting the algal biomass by these methods are high. In the technical and economical analysis on microalgae for biofuels it was shown that the investment costs for the centrifuges contributed up to 34% of the total investment on equipment. The study also showed that the ...


  • Biomass harvesting: how forest thinning can help prevent wildfires

    Every year, wildfires plague the nation. Once there’s an ignition source, dry foliage in country areas can quickly go up in flames, spreading through woodlands or grasslands quickly. While some wildfires can be small, others can be devastating and blaze through thousands of acres. While there’s no way to predict where wildfires may start, there are ways to minimize the damage of ...

  • Heterosis in switchgrass: Biomass yield in swards

    Improving the biomass yield of switchgrass (Panicum virgatum L.) will improve its utility as a dedicated energy crop by increasing both its net and total energy yield per hectare. In a previous space-transplanted study, midparent heterosis for biomass yield was reported for population and specific F1 hybrids of the lowland-tetraploid cultivar Kanlow and the upland-tetraploid cultivar Summer. ...

  • Harvesting Corn Stover and Soil Quality

    Corn stover, left in fields after corn grain harvest, has been identified as a potential feedstock to help supply biofuel needed to offset a portion of the 14 million barrels of oils consumed daily by the U.S. transportation sector. It was projected to supply 256 million tons of the 1.4 billion tons of biomass (232 million Mg out of 1.3 billion Mg) estimated to be available each year. Corn stover ...

  • Sand abrasion injury and biomass partitioning in cotton seedlings

    Wind blown soil particle abrasion negatively impacts millions of hectares of crops annually. The goal of this study was to examine the effects of wind and wind blown sand abrasion damage on cotton (Gossypium hirsutum L.) seedling biomass partitioning to leaves, stems, and roots. Seedlings of three cotton cultivars were exposed to no wind (untreated controls) or sand abrasive flux densities of 0, ...

  • Effectiveness and efficacy of conservation options after potato harvest

    Soil erosion and phosphorus (P) runoff can be severe in potato production systems in the Northeast USA, which are characterized by intensive tillage, minimal ground cover, low crop residue return, and steep slopes. We used rainfall simulators in the greenhouse and field to assess sediment and P movement associated with two conservation practices: straw mulching and application of polyacrylamide ...

  • Corn stover to sustain soil organic carbon further constrains biomass supply

    Sustainable aboveground crop biomass harvest estimates for cellulosic ethanol production, to date, have been limited by the need for residue to control erosion. Recently, estimates of the amount of corn (Zea mays L.) stover needed to maintain soil carbon, which is responsible for favorable soil properties, were reported (5.25–12.50 Mg ha–1). These estimates indicate stover needed to maintain soil ...

  • The Effect of Summer Harvesting of Phragmites australis on Growth Characteristics and Rhizome Resource Storage

    The effect of harvesting the aboveground biomass on the growth of Phragmites australis in the subsequent growing season was investigated following cutting in June or July. Seasonal changes in rhizome biomass and total nonstructural carbohydrate (TNC) in seven age categories, from newly formed to six-years-old, were monitored for the two treatment stands and a control stand. The growth of the ...

  • Growth analysis of biomass production in sole-crop and double-crop corn systems

    Increased biomass productivity could be achieved through double-cropping if extended growth duration could be realized with minimal reductions in growth efficiency relative to sole-cropping. To test this hypothesis, functional growth analysis was used to assess the relative importance of photosynthetic duration and efficiency in determining biomass production by sole-crop corn (Zea mays L.; SC) ...

  • Weed biomass and species composition as affected by an integrated crop–livestock system

    Crop and livestock production are rarely integrated together in modern farming systems. Reintegrating crops with livestock production has been shown to produce many agronomic and environmental benefits. The objective of this study was to evaluate how an integrated crop–livestock system would influence weed biomass and weed species composition compared with a conventional, continuous corn (Zea ...

  • Nitrogen influences biomass and nutrient partitioning by perennial, warm-season grasses

    Recent attention has focused on the use of perennial, warm-season grasses as renewable energy crops. The objective of this study was to assess the effects of N fertilization on partitioning of biomass and nutrients between above- and belowground plant components by four warm-season grass species in Iowa. In 2006–2007, established stands of big bluestem (Andropogon geradii Vitman), switchgrass ...

  • Nitrogen and harvest frequency effect on yield and cost for four perennial grasses

    A USDOE and USDA study concluded that more than 20 million U.S. hectares of cropland, idle cropland, and cropland pasture could be converted from current uses to the production of perennial grasses from which biomass could be harvested for use as biorefinery feedstock. This study was conducted to determine the most efficient species, level of N, and harvest frequency from among four perennial ...
