Cultivation of rice for animal feed with circulated irrigation of treated municipal wastewater for enhanced nitrogen removal: comparison of cultivation systems feeding irrigation water upward and downward
To achieve enhanced nitrogen removal, we modified a cultivation system with circulated irrigation of treated municipal wastewater by using rice for animal feed instead of human consumption. The performance of this modified system was evaluated through a bench-scale experiment by comparing the direction of circulated irrigation (i.e. passing through paddy soil upward and downward). The modified ...

Why You May Want To Purchase A Rice Husk Carbonizer
The harvesting of rice is certainly a profitable business. This the type of food that is used by just about any country. Once the harvesting is done, the residue in the harvest is usually utilized for fertilizer. Or else, it may be sent to other areas for processing. This may be a costly endeavor which may cut in the profits of any business that may be harvesting rice. However, if you could ...

World facing huge new challenge on food front: business-as-usual not a viable option
A fast-unfolding food shortage is engulfing the entire world, driving food prices to record highs. Over the past half-century grain prices have spiked from time to time because of weather-related events, such as the 1972 Soviet crop failure that led to a doubling of world wheat, rice, and corn prices. The situation today is entirely different, however. The current doubling of grain prices is ...

Characterization and greenhouse evaluation of brazilian calcined nonapatite phosphate rocks for rice
Little information is available on the agronomic effectiveness of calcined nonapatite phosphate rock (PR) sources containing crandallite minerals in the form of Ca–Fe–Al–P for flooded and upland rice (Oryza sativa L.). We conducted laboratory and greenhouse studies to (i) characterize the mineralogical composition, (ii) investigate the solubility and dissolution behavior, and (iii) evaluate the ...

A hotter planet means less on our plates
In the Sunday November 22, 2009 issue of Outlook in the Washington Post, Lester Brown discusses the significant implications of food security in the upcoming Copenhagen Conference. As the U.N. climate-change conference in Copenhagen approaches, we are in a race between political tipping points and natural ones. Can we cut carbon emissions fast enough to keep the melting of the Greenland ice ...

Nitrogen removal and power generation from treated municipal wastewater by its circulated irrigation for resource-saving rice cultivation
This study aims at improving the performance of the cultivating system of rice for animal feed with circulated irrigation of treated municipal wastewater by applying a larger amount of wastewater, as well as adding a microbial fuel cell (MFC) to the system. The results of bench-scale experiments indicate that this modification has increased the rice yield, achieving the target for the rice ...

Dissipation and residues of trifloxystrobin and its metabolite in rice under field conditions
Residue analysis of trifloxystrobin and its metabolite (CGA 321113) in rice matrices, paddy water, and soil was developed using the quick, easy, cheap, effective, rugged, and safe (QuEChERS) method and high performance liquid chromatography tandem mass spectrometry (HPLC‐MS/MS). The method was used to evaluate the dissipation rate of trifloxystrobin and CGA 321113 in rice seedling, soil, and ...

Plan B 3.0 -- A Plan of Hope
Plan B is shaped by what is needed to save civilization, not by what may currently be considered politically feasible. Plan B does not fit within a particular discipline, sector, or set of assumptions. Implementing Plan B means undertaking several actions simultaneously, including eradicating poverty, stabilizing population, and restoring the earth’s natural systems. It also involves cutting ...

Access to Energy: Empowering India’s Rural Communities
Tucked away in the southwestern corner of Odisha in the Bay of Bengal, the village of Keragam is home to around 230 families, most of whom are farmers. They live about 30km from the nearest town, while the state capital, Bhubaneswar, is an 11-hour drive away. Those who work the land here do so in relative isolation; they grow rice and sugarcane as best they can, in a patchwork of green and brown ...

Microalgal oil production for use in rice farms in Albufera (València) region
In the Albufera (València) region of Spain, rice has been farmed for nearly 500 years. Post-harvest flooding of rice fields has become an integral element of wetland refuge for migratory birds. The steady rise in the cost of purchased inputs is causing considerable economic stress to the viability of rice farming in this region. In 2011, it has been estimated the cost of purchased diesel ...

Global Grain Stocks Drop Dangerously Low as 2012 Consumption Exceeded Production
The world produced 2,241 million tons of grain in 2012, down 75 million tons or 3 percent from the 2011 record harvest. The drop was largely because of droughts that devastated several major crops—namely corn in the United States (the world’s largest crop) and wheat in Russia, Kazakhstan, Ukraine, and Australia. Each of these countries also is an important exporter. Global grain ...

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 ...

The developing world is awash in pesticides. Does it have to be?
Herbicides, insecticides and fungicides threaten the environment and human health in many parts of the world. But research is pointing to a better approach. In today’s globalized world, it is not inconceivable that one might drink coffee from Colombia in the morning, munch cashews from Vietnam for lunch and gobble grains from Ethiopia for dinner. That we can enjoy these products is thanks, ...
