Forage crop promising as ecologically friendly ornamental groundcover
A new, ecologically friendly groundcover for warm-weather landscapes is on the horizon. Rhizoma peanut, a warm-season perennial native to South America, has been used almost exclusively as a forage crop in the United States since the 1930s, but a study in the July HortScience says the perennial has potential as an ornamental groundcover or turf alternative. "Rhizoma peanut is grown in U.S. ...

New SunScan System Animated Explainer Video
The SunScan Canopy Analysis System makes fast accurate measurements of photosynthetically active radiation (PAR) in plant canopies. It also calculates leaf area index (LAI) and provides direct display of fractional interception readings. SunScan data provides valuable information about plant growth and biomass production, and is essential in work such as comparative crop studies – for ...

Model predicts shifts in carbon absorption by forest canopies
An Agricultural Research Service (ARS) scientist participated in a project to fine-tune computer models that can indicate when forest 'carbon sinks' become net carbon generators instead. The results will help pinpoint the effectiveness of trees in offsetting carbon releases that contribute to higher atmospheric temperatures and global climate change. ARS plant physiologist Erik Hamerlynck ...

Crop management: how small do we go?
The use of on-the-go crop and soil sensors has greatly increased the precision with which farmers can manage their crops. Recently released research in Agronomy Journal questions whether more precise management is necessarily more efficient. They discovered that the law of diminishing returns applies to precision agriculture, calculating how large of an application area is optimal for precision ...

New DeltaLINK Software Enables GP2 Logger to Calculate Full ASCE Penman-Monteith Equation – Improving Evapotranspiration Data Accuracy
The latest release of Delta-T Devices’ DeltaLINK Software (v3.7), in combination with its GP2 Data Logger and relevant sensors, enables the full ASCE/FAO-56 Penman-Monteith equation for calculating reference evapotranspiration (ETo). This enhancement also applies to the WS-GP2 Weather Station – an advanced research-grade system. ETo is calculated by the GP2 Data Logger using the ...

Lightning Fires May Help Preserve Oak Forests
CLEVELAND, Ohio, (ENS) - Oak forests may be approaching extinction but lightning fires canplay a role in their regeneration, according to Case Western Reserve University biologists. Paul Drewa, assistant professor in Case's biology department, and graduate student Sheryl Petersen, suspect that these kinds of fires may provide a natural mechanism to deter encroachment of shade tolerant ...

Early Spring Pasture Management
Having a blue moon is a rare sight that we were blessed with in January this year, but now as we creep slowly into spring, day length will lengthen, grass will start to take on a greener colour and temperatures will rise. This is a good time to prepare pastures for the year ahead. Grass that was closed off early last autumn should be the most advanced on farms at this stage. Pasture ...

Nitrogen recommendations based on crop reflectance
Nitrogen fertilizer is usually applied in greater quantities to corn than almost any other crop. But when it’s applied in excess of requirements, loss of the excess fertilizer to the environment can contribute to degraded water quality. One of the challenges to making an appropriate nitrogen fertilizer recommendation is the potential variability in soil nitrogen availability that may occur ...

Careful urban tree planting and pruning needed to reduce trapping of air pollution
Careful planting and pruning is needed to ensure that air pollution in tree-lined streets is minimised, new research suggests. While planting trees in urban areas can have many benefits, such as enhancing biodiversity, trees can trap particulate matter pollution, say the study’s authors. Particulate matter (PM) air pollution is a component of vehicle exhaust emissions and PM2.5 (particles ...

Plant Morphology and Spectrum: How Plants Respond to Light Quality
Light is one of the most important factors for optimizing plant growth. Plants collect energy from light to make sugars and these sugars are used for the growth of roots, leaves, stems and flowers. Plants use light for both photosynthesis and to respond to the environment to optimize their growth. Light can be described as the visible portion of the electromagnetic spectrum which extends from ...

Even small urban green spaces can help tackle the heat island effect
Green spaces in cities can have a cooling influence which helps reduce the ‘urban heat island effect’. New research from Portugal has demonstrated that even a small community garden can provide a significant cooling impact that can help efforts to adapt to climate change. Climate change is expected to cause hotter and drier summers in many locations, increasing the ‘urban heat ...

Aerial applicators now hitting the ‘bull’s eye’
Getting 6-inch accuracy on spray patterns, applying as little as 1 gallon per acre of water-chemical mixture, achieving virtually total canopy coverage and doing this while flying 140 miles per hour only 10 to 15 feet above the ground is the proficiency of today’s aerial applicators. “It’s very significant, the technology upgrades for aerial applicators the past few ...

Everest Visible Targeting System (Patent No. 7,355,178) Takes the Guesswork Out of Infrared Thermometry
For some time now, infrared thermometers, such as those manufactured by Everest Interscience, have been used to measure temperatures under less-than-ideal conditions. A major problem with infrared thermometers that frustrates the end users and prevents more widespread acceptance of infrared thermometry is the fact that the infrared measurement beam from the instrument is infrared so it is ...

No Climate Benefit Gained by Planting Temperate Forests
SAN FRANCISCO, California, (ENS) - Planting forests in temperate regions such as the United States and Europe may not yield any benefit for the global climate, and may instead contribute to warming, according to a new study set for presentation Saturday at the American Geophysical Society annual meeting in San Francisco. By contrast, trees planted in tropical rainforests could indeed help to ...
