Grazing tips for dry pastures

first_imgShare Facebook Twitter Google + LinkedIn Pinterest According to the U.S. Drought Monitor, many areas are experiencing abnormally dry to moderate drought conditions — and the impact on crops is obvious.One farmer last week told me he had to drive around a lot in his fields to make round bales. All crops are showing signs of stress, including pasture grasses and forages, but the weeds seem to be growing well through these dry conditions.What can a manager do given the current situation?Basic pasture management principles are as important, if not more so, during periods of dry weather. Maintaining good fertility and soil pH can help grazing plants survive drought conditions. Soils that have adequate fertility and are at the ideal pH will go a long way in helping plants maintain a healthy root system, which is important for capturing nutrients, minimizing soil loss, and photosynthesis.If you decide to apply nitrogen fertilizer, use a form that will not volatilize if rainfall doesn’t occur shortly following application. Nitrogen fertilizer can benefit plants even if rainfall doesn’t occur for several weeks. But be cautious when using nitrogen fertilizer during drought conditions as this practice can potentially lead to nitrate poisoning.Also, don’t overgraze your pastures. It’s critical that plants be grazed to the proper stubble height and be allowed to rest until they reach the proper grazing height. Plants should be between six and eight inches tall when grazed. This is necessary to maintain plant health and diversity in a pasture. The “take half, leave half” rule applies at all times when grazing — especially during times of drought.One of the worst things to do during a drought is to open up the gates and let livestock graze wherever and whenever they choose. Doing so prevents photosynthesis to occur and may cause long-term damage to the plants.If you have large grazing paddocks, it may be helpful to subdivide them to improve forage utilization and increase the rest period. Look for other areas that are not normally grazed, such as hay that is short, but adequate for grazing, crop residue, or farm roads that are normally mowed.Reduce the number of cows grazing. By drying off cows, the forage demand is reduced. The grazing can also be reduced by limiting the time spent grazing by keeping them in an area when they are not grazing.Closely monitor body condition of cows during drought conditions. When finishing animals on pasture, give them first choice on the best pasture and after moving them to a new pasture, let the dry animals clean up after them.Feed hay or grain in an area that will benefit from the extra nutrients provided by these feeds. Another option is to cross fence the pastures and start feeding the hay or grain on pasture to extend the grazing and spread the nutrients over more acres.If you are experiencing drought like conditions and pasture growth is minimal, consider the options to help maintain the stand and have it in a more favorable condition when rainfall resumes.last_img read more

MP Says SLB Funds Should Be Directed To Critical Areas of Study

first_imgBy Latonya Linton, JIS Reporter Member of Parliament for North West St. Ann, Dr. Dayton Campbell, is recommending that adjustments be made to the Student Loan Bureau (SLB) to focus on areas of study that are critical to nation development.“I believe the SLB should first concern itself with making loans available to persons pursuing tertiary studies in areas…such as Mathematics, Pharmacy, Engineering, the Sciences,” he stated.Dr. Campbell was opening the debate on a private members motion on funding for tertiary education, on June 11 in the House of Representatives.He stated that new programmes should be assessed for relevance, in terms of whether they “respond to labour market needs, foster innovation or serve community aspirations, before approval”.Dr. Campbell said that while he is not suggesting that persons pursuing degrees that are “oversubscribed” or those with “a low employment potential” should be denied tertiary education, the SLB’s limited resources should be directed to those areas which are of strategic importance to the country, and at lower interest rates.These rates, he noted further, “should be inversely proportionate to the need of the area for national development thus the higher the need the lower the interest rate”.According to Dr. Campbell, the country is in need of Mathematics and Science teachers and in order to increase enrolment in these areas, students should get incentives to pursue these subjects at the tertiary level.“I want to take it a step further and propose that no income tax be collected for the first three years of employment for Mathematics and Science teachers, who needed state financing to complete their studies. This portion would instead go straight to the Bureau as a part of their repayment,” Dr. Campbell said.He also proposed the establishment of an income-contingency repayment plan, which would base the monthly loan repayments on the salaries of borrowers. He noted that such a loansystem addresses risk and uncertainty faced by individuals by providing insurance against inability to repay and improves progressiveness by providing a lower public subsidy for graduates that obtain higher private returns.Demand for student loans has increased over the last six years, moving from 6,600 persons in 2007 to 16,600 in 2012, and is projected to swell to over 20,000 persons for the upcoming academic year.The growth in demand, coupled with the annual increase in tuition costs, has significantly increased the pressure on the limited resources of the SLB to provide loans, which is estimated to reach $20 billion in the 2015/16 financial year.For the 2013/14 academic year, approximately $4.9 billion is required to fully cover the projected demand, which will be financed by the Education Tax and loan inflows from the Caribbean Development Bank (CDB).On March 19, the House of Representatives approved a Government guarantee of a US$20 million loan from the Caribbean Development Bank (CDB) to the SLB.last_img read more

Rep Iden on State of the State Michigan must invest in talent

first_imgState Rep. Brandt Iden – chair of the influential Michigan House Ways and Means Committee – tonight said workforce and talent development is the key to continued success for the state and the Portage/Kalamazoo region.“We have a great opportunity to build on our recent comeback and move Michigan forward into the new decade,” said Iden, who was joined by Portage Mayor Patricia Randall for Gov. Gretchen Whitmer’s State of the State address at the Michigan Capitol. “Investing in talent development is an investment in our future. We must ensure our young people and workers of all ages have the skills needed to succeed in an ever-changing economy.”Iden, of Oshtemo Township, said he will prioritize working with the governor and Legislature to help equip students and workers with the skills needed to fill high-demand, good-paying jobs. Iden also supports policies aimed at helping job providers create new opportunities for Michigan workers, and reforming burdensome occupational licensing requirements to allow those re-entering the workforce — including those rehabilitated after serving prison time – to better provide for themselves and their families.Iden noted Michigan’s unemployment rate has dropped from 14.6 percent in mid-2009 to about 4 percent entering 2019.“The recent job growth experienced with many of Portage’s key employers shows we’re headed in the right direction,” Iden said. “Now it’s time to take the next step forward and continue the comeback with positive policy important to residents of every city, village and township in Michigan.”### 12Feb Rep.

The European Council EC has adopted new rules th

first_imgThe European Council (EC) has adopted new rules that allow consumers who pay for online TV subscriptions in their home territory access them elsewhere in the EU.The rules, which cover all forms of content services, were passed in May, meaning Netflix, Amazon and HBO Go customers will now be able to access those platforms while in other European territories.The EU has hailed the move’s importance for Europe’s Digital Single Market policy, but content distributors remain concerned it rips up their territorial business model.Essentially, distributors are concerned programmes or films they could have sold into individual territories will find no longer be of interest to buyers, as they are already in effect available.The EU says measures to protect their business models will be adopted.The rules only apply to paid-for services, though free-to-air services such as the BBC iPlayer provided by public service broadcasters can take up the system.“Europeans travelling within the EU will no longer be cut off from online services such as films, sporting broadcasts, music, e-books or games they have paid for back home,” said the Maltese presidency of the EU in a statement.“Together with the ending of roaming charges, this is important progress in creating a digital single market which benefits everyone.”To avoid “abuses”, service providers are being asked to verify subscribers’ member state of residence.The rules will start to apply from the first quarter of 2018.last_img read more

Mapping fiber layers of mammalian cerebral cortex reveals clues to their evolution

first_imgReviewed by James Ives, M.Psych. (Editor)Dec 20 2018[Background]The cerebrum plays the most important roles in the higher functions of the brain. In particular, the cerebral cortex, among other parts of the cerebrum, is essential. Humans have by far the most developed cerebral cortex among animals and it is thought that we have acquired specific abilities thanks to this. In addition, the cerebral cortex has received special attention, since various parts are involved in various brain diseases, psychiatric disorders and others.The developing cerebral cortex of higher animals like humans contains two axonal fiber layers that transmit neural information and are, therefore, considered to be important in brain functions. The cerebral cortex of the mouse, the most commonly used model animal in research, was not found to have equivalents of the axonal fiber layers, which made mouse research on this subject very difficult. Thus, research on these fiber layers has been much retarded.The present research group at Kanazawa University has been promoting studies using the ferret, since it is important to conduct research using higher animals with a more developed cerebrum, closer to that of the human than the mouse. Research techniques for the ferret were previously not available, so in 2012 and 2013 the group developed an appropriate technique, in utero electroporation, for use in ferrets at the gene level. They have thus led research into the brains of higher mammals including the development of disease model ferrets in 2015 and 2017.[Results]In the present study, the Kanazawa University group has mapped the fiber layers of the developing cerebrum of a higher mammal, the ferret, using its own unique research technique. They have also found an important clue to the evolution of these fiber layers. More specifically, the following three points have been established: A trace of axonal fiber bundles is found in the mouse brain. So far, equivalents of the two fiber layers were not described in the mouse cerebral cortex. The group applied the same technique, used to reveal the two fiber layers in the ferret brain, to the mouse brain. Unexpectedly, they found one fiber layer as well as a trace of axonal fiber bundles. This trace pathway is thought to have later evolved to become the second axonal fiber layer of higher mammals. This raises the possibility that it is this second axonal fiber layer, i.e. the outer fiber layer, which is important in the development of higher brain functions. The two axonal fiber layers have different destinations in the brain. Upon investigation of the destinations of the two fiber layers, the one on the surface side of the cerebral cortex has destinations in the proximal areas of the cerebral cortex; i.e. it represents a short-distance pathway (Figure 1 lower panel, indicated with an arrow); on the other hand, the other in the deep side of the cerebral cortex has destinations in the cerebral cortex of the opposite hemisphere and to the other brain regions; i.e. it represents a long-distance pathway. Thus, selection of the axonal fiber layers takes place depending on their destination. The two axonal fiber layers found in the human and monkey brain also exist in the ferret brain. By introducing GFP (green fluorescent protein) into neurons in the ferret cerebral cortex, it was found that axons in two fiber layers are derived from the neurons of the cerebral cortex .center_img [Significance and future prospects] In this study, the Kanazawa University group has elucidated the destinations of the two axonal fiber layers in the cerebrum and the process of their evolution with the use of their unique research technique for the ferret. This finding is of major significance, since there have been very few studies on these two fiber layers. This study should contribute to our understanding of brain evolution in higher organisms up to the human, which has been very difficult with the mouse, a conventional model animal. Further, it should help reveal causes of various brain disorders. Source:https://www.kanazawa-u.ac.jp/latest-research/63084last_img read more

Particle receivers to get first commercial trial—in Saudi Arabia

Testing heats up at Sandia’s Solar Tower with high temperature falling particle receiver This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Provided by SolarPACES What is the advantage of particle receivers?Particle receiver technology has the potential to reduce the cost of tower CSP, because it can nearly double today’s power tower temperatures, which top out in molten salt technology at 565°C.High temperatures increase efficiency, making particle receivers a good fit with high efficiency supercritical CO2 and air-breathing Brayton power cycles, and enable solar to replace fossil fuels in high-temperature thermochemical processes like splitting water to extract hydrogen at 800°C or make carbon-neutral solar fuels like jet fuels at 1,300°C.Researchers have investigated many materials for the particles. The advantage of sand is cost. At 5 MW, this particle receiver design would cycle more than 2000 tons of sand through its system.”We’re excited about sand because it doesn’t matter how much you need, the cost is almost nothing,” he pointed out. At scale, some materials, particularly engineered particles, could become a considerable fraction of initial costs. “When you are talking about thousands of tons of an engineered material, that can become prohibitive at some point.”Al-Ansary presented the paper on the results of the red sand tests in particle receiver tower CSP at the 23rd SolarPACES Conference in Chile.How the particle receiver worksAt a 20 MW-electrical scale, the receiver aperture would be about 10 meters wide by 10 meters tall and sand would be fed from the hopper to fall in a curtain a few cm thick through a 10 to 15 meter wide slot, exposing the sand particles to the heat of 1000 suns of intensely focused sunlight from a solar field of mirrors reflecting sunlight into the receiver aperture.Unlike the energy storage tanks in molten salt CSP, the hot and cold storage tanks could be stacked right inside the receiver tower along with the heat exchanger, so there is much less pumping of storage material, reducing parasitic costs.For a 20 MW plant, the tower would be about 150 meters tall and about 30 meters in diameter with the storage tanks stacked vertically inside. The discharge point of the cold tank would be about half way up the tower, “so we only need to lift the particles from the middle to the top to heat them.”The sand particles never fall fast, thanks to chevron-shaped obstacles that slow their descent, an innovation previously tested at Sandia in the US by the international research group. Without the obstacles, sand accelerates to 5 or 6 meters per second, even in just a 1 meter drop height.The obstructed flow maintains a dense curtain of particles everywhere in the receiver, so that all the concentrated radiation is absorbed by the falling particles.With particles slowed by the chevrons, Al-Ansary’s group got results of about 1,000°C in the lab without the sand agglomerating, and even out in the field, attained temperatures above 700°C.”The world’s first commercial particle receiver will be in 2018In a research field filled with innovation in much needed solar technologies, but not nearly equally visionary commercial support, the particle receiver research group is very fortunate to have backing ready to go.The Saudi Electricity Company is banking on building the world’s first commercial particle receiver, with the planning phase expected to start in the middle of 2018, following final prototype testing in January and February.”They said they are actually preparing for the next phase which is maybe around 5 MW. They would like it to be generating and they would like to sell that electricity,” he said.”Once we complete testing on KSU’s small 100 kW-electrical facility, and as soon as the results from this facility are confirmed, they are ready to go.”Saudi Electricity Company engineers have even been involved in helping with the research, and there will be an opportunity to tweak the engineering at scale.”We’ve actually had some engineers from the utility working with us on a daily basis on this project so it is really a joint effort, just making sure that we have a mature design such that when we go to the third phase it will be fully commercial.”Sandia has a much larger solar field, which was crucial and very useful in early testing, but the Riyadh test facility was small enough to be dedicated to a complete demonstration as a fully integrated power system with a heat exchanger and a gas turbine system – and a first adopter.Remote Arabian settlements need 1 GW worth of small projectsAway from Riyadh, parts of Saudi Arabia have an ideal solar resource for CSP (annual DNI of 2,600) the form of solar which needs clear skies. And many remote regions lack grid power.”Our national utility is excited about this idea because they have many remote areas that are not served by the grid, where 5 or 10 MW is more than enough,” said Al-Ansary. “They told me that the potential just within Saudi Arabia for those areas is roughly a thousand megawatts (1,000 MW). So they can build about 200 of these plants.”A 5 MW gas turbine that is adaptable to operation with hot compressed air, not steam like a molten salt system, is available commercially. This type of turbine has been tested in the EU using a direct gas heating receiver. This proven design is compatible with the PHR-CSP concept with little modification.The calm confidence with which Al-Ansary described each step from research to the impending commercialization was unusual. Even though clean technology innovation is absolutely crucial to a livable planet, such access to easy transition is rare. Al-Ansary confirmed it.”Indeed, we are lucky to have this support,” he agreed.

Credit: Sandia A new solar technology is twice as efficient, cutting the cost of solar thermal energy, by raising operating temperatures to 1,000°C, almost twice the 565°C molten salt temperature in current concentrated solar power (CSP) tower plants. For most innovative research in clean energy, the dreaded “Valley of Death” after lab scale success is the sad place where great innovations go to die for lack of commercial trials.But that will not be the case for particle heating receiver technology (PHR) that was first conceptualized at Sandia National Laboratories and is now being researched worldwide.PHR is cutting edge technology for tower CSP, a form of solar that converts the sun’s heat to power. CSP with thermal energy storage is an important key to powering a carbon-constrained future, because its thermal storage enables solar generation at any time of day or night.PHR skips the “valley of death”There is an unobstructed path from lab to commercialization for Hany Al-Ansary, Professor in Mechanical Engineering at King Saud University (KSU) and international collaborators investigating one alternative approach using a red sand abundantly available near Riyadh in Saudi Arabia.The KSU approach relies on the sand flowing through a cavity receiver in the tower, while other promising approaches use different particles in free fall, or in an enclosed receiver.Saudi Arabia will be first to commercialize particle receiver technologyThe Saudi Electricity Company (SEC) is funding and assisting with the research into using the red sand approach for heat absorption in PHRs, and intends to enter the planning phase of a commercial trial in 2018. This sort of commercial support and trial is essential to developing technologies.Like molten salts, sand loses less than 1% of its stored energy daily, but it can achieve a temperature almost twice as high. This is the main reason for the interest in particle receivers, according to Al-Ansary, who holds 15 patents and has published in peer-reviewed journals.”Molten salt is limited to around 565°C,” he said. “but depending on which type of particles, you can get much higher temperatures, up to 1,000°C. Our group worked on different containment structure designs, and with simple masonry materials and a well-insulated tank, we reduced heat loss to under 1% per day, similar to molten salt.” read more
