Developing a digital tool for forestry planning
Planning for continuous cover forestry takes longer because the transport roads must be planned extremely carefully. Otherwise, there is a risk of blockages in waterways or damage to the roots of the unfelled trees. Having the machines going into the forest several times quickly inflates the budget. Furthermore, many people think they will need to use smaller machines, but this is not the case. ...

Peroxide UltraPure™ produced directly on site improves growth and yield in super-intensive olive plantation
The Alentejo region in Portugal is known for its long sunny days, which create ideal conditions for the growth of high-quality olives. Irrigation water in the region is sourced from the Alqueva dam, and especially in the summer months it accumulates a high quantity of organic matter (algae, bacteria). This caused a problem for growers in the region specifically with drippers clogging, irrigation ...

Drones effective tools for fruit farmers
People have used the phrase “drone on and on” for a long time. Webster’s dictionary defines this figure of speech as “to speak for a long time in a dull voice without saying anything interesting.” Yet, in agriculture, drones aren’t dull, at all! Farmers use drones to be more efficient. Drones help farmers improve yields and stay ahead of problems before they ...

New method may help detect avocado pathogen earlier
University of Florida researchers have found an algorithm to help them detect laurel wilt, the deadly pathogen that threatens Florida’s $100 million-a-year avocado industry. Reza Ehsani, an associate professor of agricultural and biological engineering, said the algorithm finds laurel wilt-infected avocado trees before symptoms are visible to the naked eye. About 500 growers produce ...

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 ...

Root hydraulic conductance linked to trees` post-transplant recovery
Survival of field-grown trees grown for transplanting into landscapes depends on many factors, such as transplant timing and tree size. Species-specific characteristics also contribute to trees' ability to withstand and survive environmental stresses. In a newly published study researchers report on the relationship between tree roots' hydraulic conductance -- the roots' ability to take up water ...

Three new ornamental dogwoods introduced
In the nursery and landscape industries, flowering dogwood (Cornus florida), kousa dogwood (Cornus kousa), and their hybrids are the most popular and economically significant members of the genus Cornus. The deciduous trees are highly valued for their spring display of pink, red, or white bracts, brilliant red fall foliage, and exfoliating bark. In the United States alone, retail and wholesale ...

Agdia Releases New Molecular Test for Avocado Sunblotch Viroid
Agdia, Inc. (Elkhart, IN) has commercialized a Nucleic Acid Hybridization Assay for Avocado sunblotch viroid (ASBVd). ASBVd is found in avocado growing regions worldwide. Trees that are infected with ASBVd can result in a loss of yield and / or production of unmarketable fruit. However, symptoms are not always present making pro-active testing a critical disease control measure. Agdia's ...

Terrestrial Laser Scanning to measure forest parameters
In November landConsult completed the second service contract with a national forest adminisitration in eastern Germany. Using a FARO Focus 3D Scanner and a Stonex GNSS more than 5 heactares with thousands of broadleaf trees and conifers have been scanned. All scanned forests are part of a permanent monitoring system to research tree quality and ecological parameters. The 3D modells are stored ...

Recycled Christmas trees: mulch, dunes, habitats
It's one of America's great recycling success stories: Every year, hundreds of thousands of discarded Christmas trees are collected and reused. Many are picked up curbside by local garbage collection services and turned into mulch. But there are other second acts for Christmas trees, too. They're placed on beaches to shore up dunes and sunk in lakes as fish habitats. They've even been milled ...

Frankincense tree has not regenerated for the last half century
Frankincense is a resin that is tapped from a dry forest tree in the Horn of Africa, the Arabian peninsula and India. The European market is dominated by frankincense from Ethiopia. But the tree populations are under threat. “We found no frankincense trees younger than half a century”, says Motuma Tolera Feyissa, who defended his PhD thesis on this subject yesterday. Frans Bongers is ...

Conserving the genetic diversity of Europe’s forests
Conserving genetic diversity is vital to allow populations to adapt in the face of changing conditions. A new study, assessing the conservation of genetic diversity of trees across Europe, has identified areas for improvement that could help maintain the genetic diversity of Europe’s forests. Without a diverse gene pool, whole populations of animals and plants may be unable to adapt to new ...

Polluted urban soil damages lime trees
The impact of polluted urban soil on trees is highlighted in a recent study from Latvia. The researchers found that high salt levels from de-icing chemicals and nutrient imbalance in soil damaged lime trees growing in the city of Riga. Trees planted in cities are an important part of the urban landscape, providing a range of benefits, from enhancing biodiversity to promoting a feeling of ...

WWF rewards Pakistan for tree planting world record
Pakistan set the Guinness World Record for tree planting, beating India in a healthy and productive international competition contributing to preserving fragile and endangered forests. With 541,176 young mangroves trees planted by 300 volunteers from the local fishermen communities just in one day, the country broke the previous 447,874 record held by historical rival India. In response to the ...

Climate shift `killing US trees`, according to new study
Tree death rates have more than doubled over the last few decades in old-growth forests of the western United States, and the most probable cause of the worrisome trend is regional warming, according to a U.S. Geological Survey-led (USGS) study published in Science on January 23. The study found that the increase in dying trees has been pervasive. Tree death rates have increased across a wide ...

Loss of flowering plants: higher risks with non-random extinction
A recent study has shown that among flowering plants, species-loss does not occur randomly, but is clustered in families that contain only a small number of species. This suggests that the impact of biodiversity loss will be greater than previously thought and that resources should be targeted on particular plant families. Genetic relationships between flowering plant species (angiosperms) can ...

Growth-oriented logging: a new concept in forest management
Deforestation in the tropics has both local and global effects, but conservation remains a major challenge. New research describes a method for measuring tree growth and timber harvesting, which can lead to sustainable management of tropical timber resources. The method tailors cutting cycles according to accurate growth rates of different tree species. Research explored the Mamirauá Sustainable ...
