Influence of nitrogen fertilizer on Cd and Zn accumulation in rapeseed (Brassica napus L.) biomass
Diffuse soil contamination with heavy metals and Cd in particular is a matter of serious concern. Application of conventional remediation methods usually is not feasible due to the large territories and relatively low heavy metal content. Thus, phytoremediation is seen as an alternative. Rapeseed was grown on Cd and Zn contaminated as well as clean soil under the greenhouse conditions. Solid and ...

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 ...

Investigation on cross-compatibility barriers in the Biofuel Crop Jatropha Curcas L. With wild Jatropha species
Interspecific hybridization in Jatropha species plays a significant role in crop improvement by transferring useful traits such as yield, high oil content, maximum number of seeds, more femaleness, and hard stems for promoting Jatropha as a biofuel crop. The wide crosses among the species resulted in limited success due to pollen incompatability. Hence, the objective of the study was to assess ...

Rethinking food production for a world of eight billion
The World Food Programme and the Chinese government jointlyannounced that food aid shipments to China would stop at the end of theyear. For a country where a generation ago hundreds of millions of peoplewere chronically hungry, this was a landmark achievement. Not only hasChina ended its dependence on food aid, but almost overnight it has becomethe world’s third largest food aid donor. The key ...

Can pulse crops play a role in mitigating greenhouse gases from North American agriculture?
The atmospheric buildup of greenhouse gases (GHGs) is a serious environmental issue. Globally, agricultural activities are an important source of anthropogenic GHGs, contributing 20% of the annual atmospheric increase. Management choices largely determine if agricultural soils will be a source, a sink, or will be neutral with respect to GHG net flux. The proportion of agricultural land that is ...

Aerial color infrared photography to optimize in-season nitrogen fertilizer recommendations in winter wheat
Remote sensing in the form of aerial color infrared (CIR) photography has been shown to be a useful tool for in-season N management in winter wheat (Triticum aestivum L.). The objectives of this study were (i) to develop a methodology for predicting in-season optimum fertilizer N rates for winter wheat at growth stage (GS) 30 directly from aerial CIR photography and (ii) to quantify how the ...

No-till corn after Bromegrass: Effect on soil carbon and soil aggregates
Grasslands in the Conservation Reserve Program (CRP) in the USA may be converted to grain crops for bioenergy. The effect of no-till conversion of a smooth bromegrass (Bromus inermis Leyss) grassland to no-till corn (Zea mays L.) production on soil organic carbon (SOC) in the western Corn Belt was monitored for over 6 yr. A different 13C/12C isotope signature is imparted to SOC by C4 plants ...

Soil carbon levels in irrigated western corn belt rotations
Proposals promoting the use of massive amounts of crop residues and other lignocellulosic biomass for biofuel production have increased the need for evaluation of the sustainability of cropping practices and their effect on environment quality. Our objective was to evaluate the effects of crop rotation and N fertilizer management and their stover production characteristics on soil organic carbon ...

Energy use and carbon dioxide emissions from cropland production in the United States, 1990–2004
Received for publication June 9, 2008. Changes in cropland production and management influence energy consumption and emissions of CO2 from fossil-fuel combustion. A method was developed to calculate on-site and off-site energy and CO2 emissions for cropping practices in the United States at the county scale. Energy consumption and emissions occur on-site from the operation of farm machinery and ...

The Global Food Challenge Explained in 18 Graphics
The world is projected to hold a whopping 9.6 billion people by 2050. Figuring out how to feed all these people—while also advancing rural development, reducing greenhouse gas emissions, and protecting valuable ecosystems—is one of the greatest challenges of our era. So what’s causing the global food challenge, and how can the world solve it? We begin to answer these questions ...

Monitoring greenhouse gases from biofuel crops
Global issues such as climate change and energy security have driven rapid growth in renewable energy production - wind, solar, tidal, geothermal, hydro, biofuels etc. However, logically, each of these methods should deliver a net benefit in terms of greenhouse gas (GHG) reduction, so researchers in the United States have employed portable FTIR analysers to study the GHG emissions of biomass ...

Northam Wheat Trial – NPK Reduction - Case Study
First of a five year trial producing wheat at reduced rates of NPK (50% to 75%). At Northam in the central wheatbelt of Western Australia in 2013, wheat cv. Eradu was sown into a pasture paddock to evaluate the effects of various rates of fertiliser in combination with Hibrix BB. Agras fertiliser was banded below the seed at sowing at 0, 25, 51, 75 or 99 kg/ha whilst Hibrix BB was applied to half ...

How to Help Grapevines Recover after a Difficult Frost Period
100% : this is the percentage of a vineyard that can be damaged by frost Cold snaps and frosts have hit many orchards and vineyards these last few weeks in France. High yield reduction will be expected due to these cold waves, occurring after weeks of heat and crop development. During dormancy, grapevines can support temperatures as low as -15°C. However, as soon as the vines bud, they ...

Potential of crop residue in India as a source of energy
Here is given an estimate of crop residue production and different recycling options as a source of renewable energy. India produces 388 Tg crop residues but only 182 Tg equivalent to 2818 PJ is usable. Recycling as manure can replace 15% of 595 PJ national fertiliser energy. Recycling in digester can produce 20.32 billion m? biogas. It can be converted into 182 Tg of biocoal generating 156?258.3 ...
