Assay, straight a evaluate
Growing bio dynamic vegetables are typically planted in warm regions of the UK, especially among those farmers and landowners who have long been reliant on large agricultural land.
But new research from the University of Leicester, found that growing bio dynamic vegetables will not only improve the yield of these crops, but also bring them much-needed global agricultural benefits.
The research was published in Ecology Letters.
This work began with a series of experiments carried out with bio dynamic vegetables. Biomass biodegradation (BBD), also known as bio cycling, is an environmentally-friendly means of converting plant biomass to useful nutrients and fuels such as water, nitrogen, carbon dioxide and methane, which are then released for use by plants.
The concept of bio cycling is particularly useful for those who have a difficult time obtaining enough renewable energy to support their family and farms, or if they want to use large quantities of biomass for their own purposes.
As a result, most households use a mixture of bio dynamic vegetables and conventional varieties to harvest them to support their growing diet. However, as the number of biomass biodegradables grows, the quality and stability of the vegetable-growing methods used is increasingly being tested.
Scientists from the U of L showed, using simple mathematical modelling, that the number and quality of plants grown with biomass biodegradation could be reduced.
The results presented by the team showed that the biotechnological principles underlying bio cycling can be modified so as to improve the yield of bio dynamic vegetables and increase its utility in terms of reduced greenhouse gas emissions.
The researchers then examined how changing the biotechnological factors that control plant biodegradation could affect crop yields for a variety of plants.
The experiments used to measure the yield of the plants were done by the British Ecological Assessment Agency (BEEA), an international network of scientists which measures worldwide environmental performance.
The team then looked at how this could change if they applied the same mathematical equations found in their mathematical model of bio cycling to various plant growing conditions: hot and cool seasons; soil conditions; pH; temperature; water; growth and nitrogen fixation.
In each of the four experimental designs they applied the mathematical model applied in the model for biological cycling to the crop-growing conditions. The results presented by the team confirmed that changing the biotechnological principles underlying biotechnological cycling could improve crop yields for various bio dynamic vegetables.
The researchers showed that changing biotechnological principles could significantly reduce the amount of soil which the biotic biodegradation (bBD) was performed with: up to 75 per cent in hot and 70 per cent in cold conditions in the biodegradable crops and 70 per cent in cool and dry condition

Hope for local govt to help subsidise show power, says former president of India
By Prashant Jha
TOKYO, May 5 (Reuters) - Tokyo mayor Shintaro Ishihara, who made a name for himself rescuing stranded tourists after the 2011 tsunami, called on his city's central government to help pay for a live television broadcast that could fill more than one million homes.
More than half of Japan's 10 million television viewers, estimated at about 8.3 million, are likely to be covered by this year's KBS channel, Ishihara's office said on Sunday.
"We should send KBS to show a special episode in which people from Tokyo, Chiba, Ikebukuro and other cities would be on the receiving end of this kind of energy, and the message should be clear: Let the money come to the people so that they can use energy to improve local public services," Ishihara said on Saturday during a TV interview, according to KBS.
Overnight, KBS said it has started casting calls for three candidates. The first is a young, Japanese-Canadian actor, and the second is an actor.
Ishihara visited his city earlier this week to promote the show, the most popular TV channel in Japan in 2011 that caused a stir in Tokyo and Tokyo's western suburbs with its "We are Fukushima" campaign.
Ishihara said the KBS special series would focus on the problems people face in the aftermath of the March 11, 2011 tsunami, including food shortage and food-stamp fraud.
"It may be necessary for all kinds of services to be upgraded from the present levels of services - but people should not wait. All of the people will get a chance to vote as the final votes are taken in this year's elections," he said, according to KBS.
The KBS special broadcast will air daily on KBS at around 5 a.m. (1600 GMT) and at 3:30 a.m. (1330 GMT) and 4 p.m. (1500 GMT) in Osaka, Yokohama and other western cities. (Reporting by Prashant Jha and Denny Geller in Tokyo; Editing by Alastair Macdonald)
