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 ...

Research prunes 60 per cent off energy use
Prune Industry Advisory Committee Chair Malcolm Taylor said reducing the cost of the dehydration process was of major interest. "We were very interested in working with HAL and CSIRO to improve the cost efficiency of dehydration as it is a major proportion of total production costs," Mr Taylor said. "Through this research, we expect companies will see major savings in energy, money and green ...

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 ...

First raisin grape that dries naturally on vine developed
Agricultural Research Service (ARS) scientists in California have developed a new raisin grape that dries naturally on the vine, making it unnecessary for growers to cut into the woody “canes” connecting the grapes to the mother vine weeks before harvest. For mechanically harvested raisin grapes like Thompson Seedless, growers have to cut the canes each summer, usually about 2 weeks ...

No-tillage management of olive groves can improve soil structure while maintaining yield
Non-conservative tillage techniques, such as milling and harrowing, are the most common way to manage soil in Mediterranean olive orchards. A new study confirms the value of alternative methods based on the use of spontaneous cover crops which can significantly improve soil structure and reduce erosion whilst maintaining yields. The olive tree is one of the most widespread crops in the ...

Climate change killing trees across the Sahel, says study
Trees throughout Africa's Sahel region — vital to peoples' livelihoods — are dying as a result of long-term drought linked to climate change, according to a study. It found that one in six trees in the region has died since the 1950s, whilst a fifth of species has disappeared locally, because of rising temperatures and lower rainfall linked to climate change. At some sites, average ...

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 ...

Intercropping `boosts maize yields by 50 per cent`
Growing leguminous trees on maize farms — a form of agroforestry — can boost and stabilise maize yields, a 12-year study in Malawi and Zambia has found. The researchers behind the study, from the Kenya-based World Agroforestry Centre and the University of Pretoria, South Africa, say this is the first analysis of long-term crop yield trends in cereal-legume agroforestry systems in ...
