Zone Irrigation, Part 2 – Designing a System
A good understanding of the soil variability patterns is essential to optimally design and install a zone irrigation system. Rapid, non-intrusive methods of measuring soil electrical conductivity combined with global positioning systems (GPS) are used to map the soil variability patterns and provide waypoints to guide the design and installation. Continue reading

One concept to irrigating highly variable soils that is gaining some adoption is zone irrigation. Zone irrigation is being used in some orchard settings in the Sacramento Valley where changes in topography are gradual and variability in soil profile depth, texture, structure, and water-holding capacity exists.

New Olive Disease in California

He has isolated a putative pathogen, Neofabraea species. In addition to defoliation, leaf lesions and elongate twig lesions were also associated with this fungus. Here is a list of what we know and don’t know about this disease. Continue reading
