  • 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 ...

  • Designing a rainwater harvesting system for urban green roof irrigation

    Green roof systems have been suggested to ease the growing urban environmental problems resulting from rapid urbanization. However, the irrigation of green roofs heavily depends on using precious potable water and consequently generates negative environmental effects. Rainwater has been recommended to address this dilemma, but the design method has not been well developed. In this study, the ...

  • Modelling of a roof runoff harvesting system: the use of rainwater for toilet flushing

    The water balance of a four-people family rainwater harvesting system was calculated in a case study. The experimental water saving efficiency (WSE) was calculated as 87%. A simple computer model was implemented to simulate the behaviour of the rainwater harvesting system. In general, the rainwater collector volumes predicted by the daily model had shown a good correlation with the experimental ...

  • 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 ...

  • Household rainwater harvesting system – pilot scale gravity driven membrane-based filtration system

    This paper presents the results of a pilot scale study consisting of pre-treatment with a granular activated carbon (GAC) filter followed by membrane filtration. Detailed characterisation of rainwater tanks has highlighted that turbidity, dissolved organic carbon (DOC) and heavy metals, in particular lead, were not compliant with the 2004 Australian Drinking Water Guidelines (ADWG). Further, ...

  • Theoretical considerations on generic modelling of harvest maturity, enzyme status and quality behaviour

    There is a growing awareness amongst researchers in the field of fruit and vegetable postharvest that quality is generated in the process of plant growth and all well advanced postharvest techniques and technologies can merely retain, as good as possible, the quality that is already present in the produce. Information and knowledge about the evolution of properties and quality attributes, that ...

  • 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 ...

  • Bumper 2011 Grain Harvest Fails to Rebuild Global Stocks

    The world’s farmers produced more grain in 2011 than ever before. Estimates from the U.S. Department of Agriculture show the global grain harvest coming in at 2,295 million tons, up 53 million tons from the previous record in 2009. Consumption grew by 90 million tons over the same period to 2,280 million tons. Yet with global grain production actually falling short of consumption in 7 ...

  • Rising Meat Consumption Takes Big Bite out of Grain Harvest

    http://www.earth-policy.org/data_highlights/2011/highlights22 World consumption of animal protein is everywhere on the rise. Meat consumption increased from 44 million tons in 1950 to 284 million tons in 2009, more than doubling annual consumption per person to over 90 pounds. The rise in consumption of milk and eggs is equally dramatic. Wherever incomes rise, so does meat consumption. ...

  • Combating water scarcity through roof water harvesting: planning and design with stakeholders' perception in Sikkim (India)

    Sikkim is one of the constituent states of India, endowed with huge water resources. However, due to steep terrain and non availability of a groundwater aquifer, water conservation is a challenge. The water received as rainfall drains away through the steep terrain in the deep valleys, thereby creating a water stress after withdrawal of the monsoon. To overcome such a situation, a study was ...

  • Coffee production systems

    Types of production systems Roughly, five types of coffee production systems can be distinguished (Moguel, 1996, in Courville, forthcoming): 1)Traditional rustic coffee system: coffee production under forest trees by substitution of plants growing on the floor of a (sub)-tropical forest with coffee. There is a minimal impact on the original forest ecosystem; 2)Traditional polyculture system ...


  • Annual legumes for forage systems in the United States gulf coast region

    Forage-livestock systems in the U.S. Gulf Coast are based on perennial C4 grasses. System productivity often is predicated on significant inputs of N fertilizer, but rapidly escalating fertilizer prices raise questions about the sustainability of these systems and provide impetus for legume research. There are few successful forage legumes in the region, suggesting that alternative species merit ...

  • 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) ...

  • A method to predict weekly strawberry fruit yields from extended season production systems

    In major strawberry (Fragaria x ananassa) production areas, fruit are harvested continuously for 4 to 6 mo. During the season, weekly yields vary. To improve weekly forecasts, a yield prediction equation was developed for ‘Strawberry Festival’ using input variables derived from flower counts and temperature data over two seasons in Florida. Weekly yields are dependent on the number, size, and ...

  • Cover Crop and nitrogen effects on maize productivity in no-tillage systems of the Brazilian Cerrados

    Cover crops in direct seeding mulch-based cropping (DMC) systems can be an effective tool to optimize N management for crop production in the Brazilian cerrados. The objective of this study was to determine the effect of four cover crops on maize (Zea mays L.) grain yields in two fields that had been under DMC for 3 and 14 yr. We hypothesized that cover crops would optimize N supply to the maize ...

  • Economics of five wheat production systems with no-till and conventional tillage

    Conventional tillage (CT) continues to be used on the vast majority of land seeded to monoculture winter wheat (Triticum aestivum L.) in the Southern Plains of the United States. In the region, wheat can be grown for either grain-only, forage-only, or for both fall–winter forage + grain (dual-purpose). This study was conducted to determine the net returns of five alternative wheat production ...

  • 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 ...

  • Water footprint assessments for Jain irrigation systems case study

    Water footprint assessments were conducted for dehydrated onions and micro-irrigation systems (MIS), produced by Jain Irrigation Systems Ltd. in Maharashtra, India. A key objective was to understand the differences in the water footprints between onions grown under drip and flood irrigation, both in terms of water usage and agricultural productivity. The team was also interested in the practical ...
