Workshop Discusses Whether Agriculture Can Significantly Reduce Off-Site Movement of Soluble Nutrients
Growers who plant cover crops and vegetative systems in agriculture will find that it can tie up phosphorus in a stable phosphorus form that remains in the soil which can increase phosphorus use efficiency, according to a soil researcher from Ohio State’s College of Food, Agricultural, and Environmental Sciences. The question of whether agriculture can significantly reduce off-site ...

Less nitrogen could increase profit & sustainability
More fertilizer doesn't always mean more profit. That's one conclusion from a 10-year study conducted by Agricultural Research Service (ARS) scientists at the agency’s Soil Plant Nutrient Research Unit in Fort Collins, Colo., and colleagues at Colorado State University. From 1998 to 2008, the researchers evaluated and compared potential management strategies for reducing nitrogen and nitrate ...

Mineral content of soils key to physical and chemical behavior
Many aspects of the physical and chemical behavior of soils are directly related to the minerals present. “This includes shrink-swell behavior, soil structure, availability of nutrients, and the fate of contaminants that enter the soil,” according to Judith Turk, University of Nebraska-Lincoln. The “Soil Mineralogy” symposium at the Managing Global Resources for a Secure ...

Modern farming practices: a short term solution to soil erosion
New research shows that the damaging effects of soil erosion can be partly avoided by using modern farming methods, such as the use of fertilisers, but at a cost. An increase in the use of chemical fertilisers and pesticides, for example, is likely to have an impact on local ecosystems. A team of European scientists, lead by the Université Catholique de Louvain in Belgium, have developed a ...

Management of rice paddy fields affects greenhouse gas emissions
How rice paddy fields are managed significantly influences the release of greenhouse gases (GHGs), a recent study concludes. Permanently flooded soils release more methane than soils that are flooded and then dried between production periods, for example. In general, the researchers recommend growing other crops in dried soil between production cycles, as well as limiting nitrogen fertilisers, to ...

Star fruit could be the new “star” of Florida agriculture
It’s not just oranges that grow in Florida. Carambola, or star fruit as most in the United States call it, is gaining popularity. One researcher from Florida International University is researching how cover crops can help the sustainability of star fruit farms.“Tropical fruit production has become a prominent practice in Miami-Dade County,” says Ariel Freidenreich. “For ...

Target the crop not the soil - to reduce fertiliser use
Feed the crop not the soil’ is the message of a new review into sustainable phosphorus use. Currently, phosphorus fertiliser is applied to the soil, and plants then take it up through the roots. However, more precise nutrient management is needed on farms, the researchers say, so that the phosphorus is targeted at the crop just as it needs it. Modern agriculture is dependent on phosphorus, ...

Cranfield collaboration with business recognised at Knowledge Transfer Partnership awards
Cranfield has been shortlisted in three categories for two of its business projects at this year’s prestigious Knowledge Transfer Partnerships (KTP) Awards, which celebrate the achievements of outstanding individuals and organisations. The University’s work with Produce World, one of the UK’s largest vegetable growers and suppliers, has been nominated for the RCUK Research Base ...

Method developed to measure solute movement in soils
Scientists from Aarhus University and Aalborg University in Denmark have developed a new method for measuring the movement of solutes in intact soil. Improving on the existing method, the new procedure can be used on intact, undisturbed soil and provides more confident estimates. Movement, or diffusion, of solutes in soils is involved in many processes of agronomical, environmental and technical ...

Measuring calcium in serpentine soils
Serpentine soils contain highly variable amounts of calcium, making them marginal lands for farming. Successful management of serpentine soils requires accurate measurement of the calcium they hold. Research published this month in the Soil Science Society of America Journal shows that multiple measurement techniques are needed to accurately measure calcium content in serpentine soils. To make ...

Microbes play important role in soil’s nitrogen cycle
Under our feet, in the soil, is a wealth of microbial activity. Just like humans have different metabolisms and food choices, so do those microbes. In fact, microbes play an important role in making nutrients available to plants. A recent review paper from Xinda Lu and his team looks at different roles that various soil microbes have in soil’s nitrogen cycle. Lu is a researcher at ...

Iron deficiency in soil threatens soybean production
An expansion of soybean production into areas where soybean has seldom, if ever, been grown can be problematic for some farmers. Soils having high pH values and large amounts of calcium and/or magnesium carbonate are notoriously iron deficient. Iron deficient soils in the North Central United States are estimated to reduce soy bean production by 12.5 million bushels every year. John Wiersma, a ...

Nutrient Management Plans: A Study in Cause and Effect
It seems practical on the surface. Nutrient management plans (NMPs) should supply plants with ideal amounts of nutrients, minimize runoff, and maintain or even improve the soil condition. And the farmer behind the plan would work with a set of conservation practices designed to reduce harmful pollutants while still obtaining optimal crop yields. However, many U.S. Animal Feeding Operations ...

Increasing potato production
Despite sophisticated nutrient management of potato crops, quality and yield still see wide variability. Although nutrients are already well understood, the influence of other environmental factors remains understudied. A research team from Michigan State University conducted a study to determine how the chemical and physical properties of soil, along with the light waves the plant absorbs and ...

Writing an equation for soil success
Soil isn’t one size fits all. It may look the same under your feet – but under a microscope, that’s a different story. A plant’s roots, tiny bugs – these things can tell one soil from another quite easily. Soil scientists typically measure different aspects of soil — how much air it contains, how well it retains water, heat, and more — to determine if it ...

Soil carbon storage is not always influenced by tillage practices
The practice of no-till has increased considerably during the past 20 yr. Soils under no-till usually host a more abundant and diverse biota and are less prone to erosion, water loss, and structural breakdown than tilled soils. Their organic matter content is also often increased and consequently, no-till is proposed as a measure to mitigate the increase in atmospheric carbon dioxide ...
