#Roses, Wine or Chocolate: Weather Controls it All This article was provided by Accuweather. com. With Valentine's day right around the corner everyone is searching for the perfect gift for their loved one.
From roses to chocolate and wine weather plays an important role in production. Roses The biggest weather-related factor in the production of beautiful roses is the temperature.
A rose bush can suffer damage if the temperature falls below 55.4 degrees F (13 degrees C) or if it exceeds 86 degrees F (30 degrees C). Ideally the roses grow best with a daytime temperature between 68 degrees
F (20 degrees C) and 82.4 degrees F (28 degrees C a variation of only a few degrees too warm can spell tragedy for rose growers To control the temperature the rose bushes are exposed to many commercial rose growers

#Is Industrial Hemp the Ultimate Energy Crop?(Op-Ed) This article was published originally at The Conversation.
Industrial hemp is said to be just that. Enthusiasts have been promoting the use of industrial hemp for producing bioenergy for a long time now.
With its potentially high biomass yield and its suitability to fit into existing crop rotations hemp could
not only complement but exceed other available energy crops. Hemp Cannabis sativa originates from western Asia and India and from there spread around the globe.
For centuries fibres were used to make ropes sails cloth and paper while the seeds were used for protein-rich food and feed.
Interest in hemp declined when other fibres such as sisal and jute replaced hemp in the 19th century.
Abuse of hemp as a drug led to the prohibition of its cultivation by the United nations in 1961.
When prohibition was revoked in the 1990s in the European union Canada and later in Australia industrially used hemp emerged again.
This time the car industry s interest in light natural fibre promoted its use. For such industrial use modern varieties with insignificant content of psychoactive compounds are grown.
Nonetheless industrial hemp cultivation is prohibited still in some industrialised countries like Norway and the USA.
Energy use of industrial hemp is limited today very. There are few countries in which hemp has been commercialised as an energy crop.
Sweden is one and has a small commercial production of hemp briquettes. Hemp briquettes are more expensive than wood-based briquettes but sell reasonably well on regional markets.
Large-scale energy uses of hemp have also been suggested. Biogas production from hemp could compete with production from maize especially in cold climate regions such as Northern europe and Canada.
Ethanol production is possible from the whole hemp plant and biodiesel can be produced from the oil pressed from hemp seeds.
Biodiesel production from hemp seed oil has been shown to overall have a much lower environmental impact than fossil diesel.
Indeed the environmental benefits of hemp have been praised highly since hemp cultivation requires very limited amounts of pesticide.
Few insect pests are known to exist in hemp crops and fungal diseases are rare. Since hemp plants shade the ground quickly after sowing they can outgrow weeds a trait interesting especially for organic farmers.
Still a weed-free seedbed is required. And without nitrogen fertilisation hemp won't grow as vigorously as is suggested often.
So as with any other crop it takes good agricultural practice to grow hemp right.
Being an annual crop hemp functions very well in crop rotations. Here it may function as a break crop reducing the occurance of pests particularly in cereal production.
Farmers interested in cultivating energy crops are often hesitant about tying fields into the production of perennial energy crops such as willow.
Due to the high self-tolerance of hemp cultivation over two to three years in the same field does not lead to significant biomass yield losses.
Small-scale production of hemp briquettes has also proven economically feasible. However using whole-crop hemp
(or any other crop) for energy production is not the overall solution. Before producing energy from the residues it is certainly more environmentally friendly to use fibres oils or other compounds of hemp.
Even energy in the fibre products can be used when the products become waste. Recycling plant nutrients to the field such as in biogas residue can contribute to lower greenhouse gas emissions from crop production.
Sustainable bioenergy production is not easy and a diversity of crops will be needed. Industrial hemp is not the ultimate energy crop.
Still if cultivated on good soil with decent fertilisation hemp can certainly be an environmentally sound crop for bioenergy production and for other industrial uses as well.

#Bees'Salt-Sensing Feet Explain Swimming pool Mystery The first-ever investigation of the honeybee ability to taste with their front feet may explain a persistent bee mystery:
Why they swarm saltwater swimming pools. Saltwater swimming pools don't require chlorine or other chemicals but online home and garden forums are full of complaints about these swimming holes'dark side.
Apparently they attract honeybees en masse. Now scientists find that bees have taste receptors on their feet that are so sensitive to salt that they even dwarf the bees'capacity to taste sweets.

Instead the models suggest that carbon dioxide rose about 40 ppm to 285 ppm and methane jumped to 790 ppb a 345 ppb rise as early humans chopped down trees

Goblin sharks live in the deep ocean more than 200 meters 660 feet down where they would never encounter a human said Chip Cotton a fisheries ecologist at Florida State university.

This change in our agricultural system has led to the near extermination of milkweed from huge swaths of our country.
Scientists now estimate that in the span of about 10 years (from 1999-2010) there has been a 60 percent decline in milkweeds across the Midwest (in both agricultural and nonagricultural areas) and an 80 percent decline in monarchs in the Midwest.
However given that the widespread adoption of Round up Ready crops has eliminated largely the monarch's most essential habitat by removing milkweeds from the landscape it's time to reconsider

so it doesn t rapidly kill its host said study co-author James Westwood who has the awesome title of professor of plant pathology physiology and weed science at Virginia Tech in Blacksburg Virginia.
Once the weed coils around its host plant it uses sharp appendages called haustoria to penetrate the host's tissue and suck out sugars and other nutrients.
along with these nutrients the weed also transports RNA the genetic material cells use to translate instructions in the organism's DNA into cellular machinery or proteins.
A much smaller amount of mrna flowed between the weed and the tomato plant the researchers found.
At the same time the weed is also sending messages to the host plant which may be operating like a genetic Trojan horse making the host more susceptible to the invading plant Westwood said.
If anything could be said to grow like a weed it is kudzu. It grows at an impressive rate of up to a metre every three days.

#As Milkweed Disappears, Monarchs are Fading away (Op-Ed) Peter Lehner is executive director of the Natural resources Defense Council (NRDC).
From 1999 to 2010 roughly the decade after glyphosate use took off milkweeds declined 60 percent in the Midwest
Without milkweed to sustain each new generation the migration will fail. Many of us are sensing the loss already.
Monarchs need milkweed and the widespread use of glyphosate is wiping it out. This knowledge gives the EPA an opportunity to muzzle a direct threat to butterflies.
Feeding bees may help them stave off illness the agency hopes particularly in an agricultural landscape dominated by corn soybean and cotton not the insects'preferred plants.
