first_imgShare Facebook Twitter Google + LinkedIn Pinterest In terms of the Right Rate component of the 4Rs, the folks at AgroLiquid are taking a novel approach to finding it through research and unique method of monitoring the fertility in the liquid between the soil particles.Using a series of syringes attached to tubing placed at varying depths beneath the soil, the soil solution underground can be carefully extracted. The nutrient levels in the solution can then be compared to nutrient application rates to get a handle on what the plants are using and what is being lost.“We have developed this method of how to test nutrients in soil solutions to see how much is lost. What we are doing has the potential to change how the industry approaches fertility and the loss of nutrients,” said Nick Bancroft, vice president of AgroLiquid. “We test the nutrient solution to see what nutrients are moving in the soil and compare that to what was applied and see what amount was used and what amount was lost. You can figure the math backwards. This lets us compare products in terms of optimal yield and minimal nutrient loss, which is really what everyone is after.”This unique soil testing method uses micro-lysimeters made of micro-porous hydrophilic Teflon. This enables an improved suction of soil solution to measure plant usable nutrientsZouheir Massri, with AgroLiquid, stands with a display that shows how the soil solution sampling method works. dissolved in the soil solution.To test advantages of using phosphorus encapsulated by Falvonol Polymer Technology preventing fixation with soil cations, for example, hydrophilic lysimeters were installed horizontally in solid soil at 10 centimeters and 20 centimeters beneath soil surface (below the corn seed and phosphorus placed in furrow at five centimeters deep). The lysimeters were connected to a transparent PVC tube at the soil surface and extended with a flexible piece of PVC tubing for easy connection-disconnection with 30-milliliter vacuum polycarbonate syringes for suction of the soil solution and measurement of dissolved phosphorus, said Zouheir Massri, who leads the research effort for AgroLiquid. “Knowledge of ion exchange in soils would predict that anions are not retained by the negative charged soil colloids, and move in the soil similar to nitrogen. But phosphorus moves very little, or is relatively immobile in the soil compared to nitrogen and is not lost into the atmosphere. Rarely does it leach beyond the reach of roots, even with large amounts of precipitation or irrigation. This apparent anomaly is that the soil solution contains only a very small amount of available phosphorus in ionic forms at any one time, knowing that the soil solution levels for phosphorus are considered critical for plant growth. That is important because crops take up phosphorus only from the soil solution, and was the core of our testing method to measure the soil solution content of dissolved phosphorus by lysimeters solution suction.”AgroLiquid is also using unique methods for nitrogen research work. Because nitrogen can be lost through both volatilization and leaching, two tests are conducted for nitrogen loss. There is one for assessment of the nutrients that flow in soil with lysimeters and the other is for ammonia volatilization in the atmosphere. To test volatilization, passive samplers are filled with 20 milliliters of a diluted sulfuric acid and placed in the center of each treatment to trap the ammonia as “ammonia collectors.”“The solution of the ammonia collectors in the passive samplers continuously absorbs ammonia, and is replaced regularly depending on the expected intensity of the emissions,” Massri said. “The principle underlying this method is that the passive samplers placed in a homogeneous experimental field…have the same NH3 absorption behavior under identical environmental conditions.”The passive sampler method was developed in the 1970s and proven valid under a wide range of experimental conditions and is recommended to be used under conditions with bare and/or cultivated soils.Ultimately, the ongoing research at AgroLiquid is showing that the right rate can be significantly lower while maintaining crop productivity if the other three Rs are correct.“From the beginning we created products that were more effective per pound applied, which allowed growers to apply less total nutrient. It also allows for placement closer to where the plant is going to utilize the nutrients, which prevents offsite nutrients. It allows us to use the right rate and right formulation. at a low rate. It is the right source because it allows you to do the other three Rs,” Bancroft said. “The industry reaction as a whole has been to try and use the products they have always been using. I think it is our responsibility moving forward in educating people that they can get away with reduced rate fertility if they are using the 4Rs.”last_img

Are lock-ups the key to solving London’s housing crisis?

first_imgLondon’s housing crisis could be eased if the capital’s 22,000 unused lock up garages were to be turned into 16,000 one-bedroom flats, it has been claimed.Property crowdfunding platform Property Partner canvassed London’s 32 London boroughs to find out how many lock-up garages each one owned, and how many of them were rented out.It found that there are 53,640 lock-ups in the capital but that 41% of them are either empty or in a state of disrepair.The boroughs with the largest property of empty lock-ups include Ealing (74%), Havering (72%), Brent (71% and Enfield ((70%) which between them have over 6,000 garages lying idle.Property Partner says the unused garages were sold and the land given over to developers, some 16, 100 one-bedroom 500 sq ft apartments could be built in their place, and if multi-storey blocks built in their place instead, 64,000 flats built.The London assembly recently said London needs between 49,000 and 80,000 extra homes built every year to keep up with demand.“When we have a crisis in affordable housing not just in the capital but in the UK, it begs the question whether councils in Britain should either sell off the land for development or build new homes themselves,” says Dan Gandesh, CEO of Property Partner (pictured).“If a significant number of council garages, which are part of housing estates, are not even rented to those who should have a right to them – local authority tenants – then it could be argued that this is a wasted opportunity.”lock up garages Property Partner January 16, 2017Nigel LewisWhat’s your opinion?

ABA Commission Sees Need For ‘Regulatory Innovations’ In Legal Profession

first_imgMarilyn Odendahl for www.theindianalawyer.comFinding the need for legal services among the poor and moderate-income greater than legal aid and pro bono can satisfy, an American Bar Association commission is advocating for the consideration of “regulatory innovations” which include non-lawyer ownership of legal service providers.The ABA Commission on the Future of Legal Services released its findings and suggestions Friday for providing legal assistance to those who cannot afford an attorney. A product of two years of study, the 96-page “Report on the Future of Legal Services in the United States” offered 12 broad recommendations ranging from embracing technology for the delivery of legal services to putting more resources into traditional legal aid and pro bono efforts.“The legal profession, as the steward of the justice system, has reached an inflection point,” the commission stated in the report. “Without significant change, the profession cannot ensure that the justice system serves everyone and that the rule of law is preserved. Innovation, and even unconventional thinking, is required.”Driving the need for change is the growing numbers of those who do not have access to affordable legal services.The commission found that most people living in poverty and the majority of moderate-income households do not receive the legal help they need. Largely, these individuals either cannot afford a lawyer or they do not realize their problem requires the help of an attorney. In addition, the traditional business model of law offices constrains innovations that, the commission maintained, would enable greater access to and enhance the delivery of legal services.Among the recommendations is the call for the continued examination of alternative business structures. In an issues paper released in April 2016, the commission noted these structures typically allow non-lawyers to own law firms, invest in law practices or operate as a multidisciplinary practice which provides both legal and non-legal services.Reaction to the issues paper was strong and divided.The ABA Section of Family Law provided a two-sentence response that asked, “WHAT PART OF ‘NO!’ DO YOU NOT UNDERSTAND? We remain unalterably opposed to these repeated, previously failed efforts to foist ABS upon on profession or our ethics.”Similarly, the Illinois State Bar Association raised concerns about the effect non-lawyers would have on the core values of the legal profession. The ISBA feared the pressure would increase on generating a greater profit which would reduce individualized care while reducing the desire to take on unpopular causes or do pro bono work.On the other side, LegalZoom and Avvo supported easing regulations.In a 10-page response, LegalZoom asserted, “It is time to examine the system that lawyers created and practice in, and the self-granted monopoly that lawyers legislate, regulate and adjudicate. If the profession can look past the fear-mongering of entrenched Luddities, and re-look (at) the purpose behind what has become innovation-crushing regulations to address supply, not only will the industry see quantum leaps in legal access, it will see a call for more, not fewer, lawyers!”The ABA Business Law Section’s Ad Hoc Working Group on the Future of the Delivery of Legal Services applauded the commission for exploring innovation proposals. It also underscored the need to not only provide legal assistance to the public but also to ensure consumers are protected.“There is a clear recognition that changes are in the wind and that it would be a disservice to our profession and the public to not provide for a structure for change,” the Ad Hoc Working Group wrote.The ABA Commission on the Future of Legal Services acknowledged the opposition to alternative business structures. However, it pointed to studies from the United Kingdom and Australia that have shown that these structures have not harmed clients and consumers nor deteriorated lawyers’ ethics or professional independence.The commission reiterated that ABS should continue to be explored and, in conjunction, that data should be collected to further assess the risks and benefits.On a related issue, the commission also advocated for states to explore the increasingly wide array of entities that employ new technologies and internet-based platforms to provide legal services directly to the public. Although conceding these businesses operate without the oversight of courts or judicial regulatory authorities, the commission advised caution and careful study before adopting any new rules.Greenwood, Indiana, attorney Patrick Olmstead Jr. responded to the issues paper that was submitted on the legal service providers. He maintained that any company offering legal services should be subject to the Rules of Professional Conduct and be liable for professional negligence.“Although most of my information is anecdotal, I believe that some clients suffer harm because documents with legal consequences are drafted poorly or the documents were not suitable for the client’s situation,” Olmstead wrote. “If a lawyer drafted those documents, the lawyer could be liable for negligence. I would like to see these legal services companies held to the same standard of care as attorneys, and follow the same rules governing lawyers, to protect the public.”FacebookTwitterCopy LinkEmailSharelast_img
