#Iron-rich biochar filters arsenic from water Biochar may be a fast inexpensive and easy way to remove arsenicâ one of the world s most common pollutantsâ from water.

Because biochar can be produced from various waste biomass including agricultural residues this new technology provides an alternative

The resulting biochar which has the consistency of ground coffee was treated then with a saltwater bath to impregnate it with iron.

Plain biochar does not have the same effect Gao says. Current methods to remove arsenic include precipitation adding lime

Water treatment plants could use large biochar filters to extract the arsenic. Homeowners could use a small filter attached to their tap.

#Biochar changes how water flows through soil Rice university rightoriginal Studyposted by Jade Boyd-Rice on September 25 2014new research could help settle the debate about one of biochar s biggest benefits#its seemingly contradictory ability

or biochar to soil to both boost crop yields and counter global climate change the study offers the first detailed explanation for this mystery. nderstanding the controls on water movement through biochar-amended soils is critical

to explaining other frequently reported benefits of biochar such as nutrient retention carbon sequestration and reduced greenhouse gas emissionssays lead author Rebecca Barnes an assistant professor of environmental science at Colorado College who began the research as a postdoctoral research associate at Rice university.

Biochar can be produced from waste wood manure or leaves and its popularity among DIY types

and gardening buffs took off after archaeological studies found that biochar added to soils in the Amazon more than 1000 years ago was still improving the water-and nutrient-holding abilities of those poor soils today.

Studies over the past decade have found that biochar soil amendments can either increase or decrease the amount of water that soil holds

In the new study biogeochemists at Rice conducted side-by-side tests of the water-holding ability of three soil types#sand clay and topsoil#both with and without added biochar.

The biochar used in the experiments derived from Texas mesquite wood was prepared to exacting standards in the lab of Rice geochemist Caroline Masiello a study coauthor to ensure comparable results across soil types. ot all biochar

is created equal and one of the important lessons of recent studies is that the hydrological properties of biochar can vary widely depending on the temperature

and time in the reactormasiello says. t s important to use the right recipe for the biochar that you want to make

When biochar is added to clay it makes the soil less dense and it increases hydraulic conductivity

which makes intuitive sense. dding biochar to sand also makes it less dense so one would expect that soil to drain more quickly as well;

but in fact researchers have found that biochar-amended sand holds water longer. tudy coauthor Brandon Dugan assistant professor of Earth science at Rice says e hypothesize that this is likely due to the presence of two flow paths

for water through soil-biochar mixtures. One pathway is between the soil and biochar grains

and a second pathway is water moving through the biochar itself. arnes says the highly porous structure of biochar makes each of these pathways more tortuous than the pathway that water would take through sand alone.

Moreover the surface chemistry of biochar#both on external surfaces and inside pores#is likely to promote absorption

and further slow the movement of water. y adding our results to the growing body of literature we show that

when biochar is added to sand or other coarse-grained soils there is a simultaneous decrease in bulk density

but will have less of an environmental impact such as varieties that require less water fertilizer and pesticides. ardy high-yield crops will become increasingly vital for human survival as the world faces the environmental effects of climate change and an ever-growing global population.

It also extracts nutrients that can be reused as fertilizer. Currently the system produces about 50 gallons of water from 100 gallons of manure.

and can be reused as fertilizer . or example, wee able to capture a large percentage of the ammonia that would otherwise be lost in the atmosphere,

and coastal waters where fertilizer runoff and other organic waste can deplete oxygen levels and suffocate marine life.

The recommendations published in the Academy s Colloquium Reports set a goal of increasing yields by 20 percent over the next 20 years by enhancing the use of microbes while reducing the use of pesticides and fertilizers by 20 percent.

and lessen the need for costly fertilizers and pesticides says team member Gwyn Beattie a professor of plant pathology and bacteriology at Iowa State university.

it can additionally advise users on how often fertilizer should be applied this stops farmers from wasting money by over-fertilizing,

and minimizes the amount of excess fertilizer entering the environment. It estimated that the system could lead to a reduction in fertilizer use of up to 30 percent

and fertilizer as we think they need. Yet field conditions may differ drastically within a few feet.

Building on existing geolocation technologies, future swath control could save on seed, minerals, fertilizer and herbicides by reducing overlapping inputs.

Due to the excessive use of fertilizers, our groundwater is contaminated with nitrates, which pose a problem

if biochar a byproduct of the a process that converts plants materials into biofuel could be used in place of expensive activated carbon to make electrodes for supercapacitors.

and the biochar nanoparticles can create an extremely large surface area which can then hold more charge.

He deposits the biochar on a substrate using a patent-pending electrochemical process he developed

Through this project Fan developed a faster way of treating the biochar particles using a new technology called plasma activation.

The plasma treatment activates the biochar in five minutes and at room temperature Fan explained. Conventional chemical activation takes several hours to complete

The technique that treats biochar electrodes for supercapacitors can also be used in making displays explained Fan who was a research scientist at Wintek more than 10 years ago.

Even though metal nanoparticles are used variously in industrial, pharmaceutical and agricultural (fertilizer) applications as a catalyst, toxic liquids such as toluene and hexane are used usually as solvents in the carbon-carbon

but fertilizer and pesticide use will more than double. To feed a hungry growing world agricultural ecologists need to know who will be eating more meat and where.#

#Biochar from manure waste enhances soils Researchers at Universidad Politécnica de Madrid have obtained biochar using manure waste,

Biochar, a material obtained after thermal treatment of this waste through pyrolysis, is an organic fertilizer that applied in soils

This waste contains fertilizers, and its production has increased over the last years because of intensive farming and has been used traditionally in soils as an organic amendment.

It is highlighted the thermal treatment through pyrolysis for large scale production of biochar or biocarbon that can be defined as a carbonaceous material obtained through thermal treatment of biomass at low temperatures and under inert atmosphere.

and Mining engineering and Agricultural production of UPM shows that the biochar produced from manure of cattle,

These results give evidence of the positive effects of using biochar as a fertilizer on soils for better crop yields.

The remaining solid is applied as a fertilizer on the fields in the vicinity. It is our vision for the future that such plants in the urban area are served by tank vehicles

There the organic wastes are converted into biogas and fertilizer within a period of one month. Via a pipeline system the gas is passed directly on to the gas stoves of the neighboring houses.

and used as a fertilizer. At first we had to work hard to convince the population Fuchs says.

and to lower environmental impact since this fertilizing system represents an alternative to the mineral fertilizers used so far.

This method can help increase crop yields its application is similar to use a fertilizer but having better results

and without the contamination issues than can produce the mineral fertilizers. Thus its application in agriculture horticulture forestry plants ornamental plants or any other plant with commercial interest would represent a significant environmental and economic saving.

and create biochar a highly porous charcoal said project principal investigator Karl Linden professor of environmental engineering.

The biochar has a one-two punch in that it can be used to both increase crop yields

Biochar is a valuable material said Linden. It has good water holding capacity and it can be used in agricultural areas to hold in nutrients

A soil mixture containing 10 percent biochar can hold up to 50 percent more water and increase the availability of plant nutrients he said.

Additionally the biochar can be burned as charcoal and provides energy comparable to that of commercial charcoal.

and can save irrigation water labor energy and fertilizer. The authors of a report published in Horttechnology said that the use of sensor-based irrigation technology can also accelerate container and greenhouse plant production time.

Sensor-based irrigation systems substitute capital for water and associated inputs such as energy labor and fertilizer the authors explained.

#A Nimble-Wheeled Farm Robot Goes to Work in Minnesota This summer a Minnesota startup began deploying an autonomous robot that rolls between corn plants spraying crop fertilizer.

The robot applies fertilizer while the plant is rapidly growing and needs it most. This eliminates the need for using tractors,

and reduces the amount of fertilizer needed earlier in the season, says Kent Cavender-Bares, CEO of the company, Rowbot.

Further, by reducing the fertilizer, the robot reduces the amount of nitrogen that can end up polluting waterways after rainstorms.

at a charge of $10 per acre plus the cost of fertilizer. Rowbot system is part of a technological revolution in farming that has gained momentum in recent years.

GPS-guided tractors routinely apply seed and fertilizer across large areas, and new airborne drones are providing farmers with high-resolution sensing ability (see gricultural Drones,
