John Deere Introduces Narrower Stick Booms for M-Series Tracked Harvesters
To help loggers maximize timber quality, John Deere has upgraded its harvester stick boom attachment across all 800MH- and 900MH-Series tracked harvesters. The new stick boom geometry delivers the same high level of boom envelope performance, but with a narrower design to help operators minimize damage to harvested trees. "Avoiding unnecessary damage to harvested trees while operating out in ...

Brick kiln emissions affect crop yields, study finds
Hydrogen fluoride emissions from brick kilns have been found to damage trees and crops in new studies conducted by an international team of scientists in the Peshawar area of northern Pakistan. Peshawar has 450 brick kilns and hydrogen fluoride is also released by factories making aluminium, ceramics, and phosphate fertilisers. Reporting their findings in the February issue of Environmental ...

Selective breeding could save trees from drought
Trees with high wood density tend to survive better under drought conditions. In a new study on Douglas-fir tree populations, research suggests that the trees could be selectively bred for high density wood to increase resistance to drought. With predictions that the frequency of droughts could increase over the coming century, such strategies to protect tree populations could aid climate change ...

Florida citrus growers: 80 percent of trees infected by greening
Florida’s citrus growers say as much as 90 percent of their acreage and 80 percent of their trees are infected by the deadly greening disease, which is making a huge dent in the state’s $10.7 billion citrus industry, a new University of Florida Institute of Food and Agricultural Sciences survey shows. The survey, conducted in March 2015, shows the first grower-based estimates of both ...

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 ...

Tree breeding programme to fight ash dieback recommended by study
A recent study confirms that some European ash trees are more genetically-resistant to the devastating ash dieback disease. These individuals could therefore be selected for gene conservation and/or start a breeding programme to save the European ash. Ash trees (Fraxinus excelsior L.) across Europe are dying from a newly recognised fungal infection, Chalara fraxinea T. Kowalski. First observed ...

Philippine coconut farmers struggling to recover from typhoon
Coconut farmers in the Philippines are in urgent need of assistance to recover their livelihoods nearly three months after Typhoon Haiyan tore through the country, FAO warned today. The typhoon flattened millions of trees when it made landfall in November and the country’s second largest coconut-producing region, Eastern Visayas, was one of the areas most affected. In this region alone ...

Choice of tree species and site can increase plant diversity in plantation forest
Careful choice of tree species and sites could transform plantations into refuges for woodland plant diversity, new research from Ireland suggests. Plantations of native species on or near historic woodland and those with adequate light levels below the tree canopy were found to support more plant species. Europe’s forests cover 45% of the land area, and provide important habitat for many ...

Microscopic molecules can fight citrus greening bug with less insecticides
Researchers with the University of Florida and several other institutions have found a way in laboratory tests to use 200 times less insecticide and yet still kill as many insects that carry the devastating citrus greening bacterium. It is a step forward in ridding groves of the insect that is threatening to destroy Florida’s $10.7 billion citrus industry. Lukasz Stelinski, an associate ...

Need to know what to spray on citrus trees to keep bugs at bay? There’s an app for that
Florida has nearly 70 million citrus trees on more than 531,500 acres. Now imagine trying to figure out what pesticide to spray on each of those trees to keep them safe from citrus greening. University of Florida researcher James Tansey says the answer is as close as your Android smartphone with a new app developed with ZedX, an information technologies company based in Pennsylvania. The free ...

Six months after disaster, Philippine farmers bring in the harvest
Tens of thousands of farmers are bringing in their first rice harvest just six months after one of the worst typhoons to ever hit the Philippines left their fields in tatters and their livelihoods at risk, FAO announced today. After Typhoon Haiyan hit the central Philippines on 8 November, 2013, the situation was dire. More than 6,000 people lost their lives, while some 600,000 hectares of ...

Machine harvesting may increase apple supply for hard cider market
Cider - or "hard cider" as it is typically known in the United States - is experiencing a real revival. The fermented apple juice with 0.5% to 7% alcohol-by-volume is the fastest growing alcohol market segment in the US, boasting a 54% increase in production annually from 2007 to 2012. Naturally, increasing consumer demand for cider translates to a need for more apples to make quality cider ...

Greenhouse Gases Rise From Forests Damaged by Katrina
Losses inflicted by Hurricane Katrina on Gulf Coast forest trees are great enough to cancel out a year's worth of new tree growth in other parts of the country, according to a new study led by biologist Jeffrey Chambers of Tulane University. 'The carbon that will be released as these trees decompose is enough to cancel out an entire year's worth of net gain by all U.S. forests. And this is ...

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 ...

Tree topping increases safety risks and expense, say tree care experts
“Topping,” “hat-racking” and “de-horning” – all names for a non-standard pruning procedure that severely cuts back large trees to a predetermined size – has long been considered an easy and inexpensive way to manage the size and improve the safety of mature trees. Researchers, however, are cautioning that topping can increase safety risks and result in greater expense for the consumer . . . not ...
