  • Nitrogen mineralization from eucalyptus yardwaste mulch applied to young avocado trees

    Consistent use of mulches over several years can provide significant N to avocado. Study of a 3-year-old Ventura, California, avocado orchard mulched annually for 3 years with 12–14 Mg ha–1 chipped eucalyptus showed that total N in the mulched soil was double that of the control. Mulched intact soil cores released 53 kg ha–1 more N annually than control treatments. A litterbag study showed that ...

  • Some initial changes in `Hass` avocado (Persea Americana Mill.) physiology due to ethephon

    Ethylene is used commercially to hasten ripening of avocados, but the presence of ethylene in the storage atmosphere can increase the risk of physiological disorders. To investigate the short term effect of ethylene on avocado physiology, fruit were dipped in a low concentration ethephon solution. The ethephon treatment significantly increased the ethylene production rate of avocados after 6 h, ...

  • Expertise and equipment: key components in San Diego county compost site’s success

    Despite readily-available evidence to the contrary, many municipalities cling to the belief that implementing a compost program is costly, time consuming and offers no real benefit to the community. As a result, they either shy away from undertaking a composting effort entirely or — in a sort of self-fulfilling prophecy — grudgingly implement a bare-bones program. North San Diego County ...

  • Munchinator reduces trash to compost-like product

    The contraption looks a bit like a sophisticated high school science project as it rocks back and forth, with steam escaping and a slight rumble reverberating in the large room. The Munchinator is at work. A team of representatives from Carson City-based Ecologico Logic Inc. brought a prototype of their machine from their ...

  • Coffee production systems

    Types of production systems Roughly, five types of coffee production systems can be distinguished (Moguel, 1996, in Courville, forthcoming): 1)Traditional rustic coffee system: coffee production under forest trees by substitution of plants growing on the floor of a (sub)-tropical forest with coffee. There is a minimal impact on the original forest ecosystem; 2)Traditional polyculture system ...


  • Building state’s compost markets

    Several research projects now under way have the potential to significantly expand the compost market in California. Californians generate 93 million tons of solid waste annually. The Integrated Waste Management Act of 1989 (AB 939) established the CIWMB and gave it the responsibility to oversee, manage and track all of this material. Expanding the opportunities for composting organic materials ...
