There is no doubt that water is a precious resource, particularly in drought prone regions like California. It is very important for growers to measure soil moisture and there are a bevy of technological devices available to utilize. From soil moisture probes to pressure bombs, these tools are helpful but, they only provide data on once specific area at a time and many are time consuming to use. T...

Using sheep to graze vineyards has many benefits including lowering the carbon footprint, fewer tractor passes, and reduced herbicide use. Kelsey Brewer, Ph. D. Candidate at the University of California at Davis has been researching how these living lawnmowers impact nutrient and energy flows in the eco system. When tractors were replaced by sheep, the research team found that vineyards had 1.3 ti...

What, bury charcoal in the vineyard? Biochar is a specialized form of charcoal made from waste woody biomass at high temperature in the absence of oxygen. We know soil organic matter is important for the health of any crop. It turns out the use of charwood (biochar) goes back to ancient civilizations and it can be found naturally in soils from fire events. Doug Beck, Science Officer at Monterey Pa...
