  • 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 ...

  • 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 ...

  • 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 ...
