SPREADING COMPOST and LIMESTONE in the NORTH COAST OF CALIFORNIA, early 1980’s
European wine producers have spent hundreds of years defining and promoting quality in their product. The sensory experience of wine tasting encompasses general appearance, color, bouquet and flavor. The general consensus is that quality lies in the fruit. The interaction of the soil with the climate, cultivar, and cultural practices is described by the French as terroir. A Training Program for Soil Analysis Interpretation in Northern California (Young, 1999) was an attempt to combine my professional experience in northern California tree fruit and vine production with the many contributions of the scientific literature into a concise educational program to teach farmers, advisors, and fertilizer technicians how to achieve optimum terroir through nutritional management. Quality and health in fruit production through a positive soil building program is the goal - and good yields of high quality fruit will follow.

Thousands of acres of wine grapes and tree fruits in the North Coast of California have benefited from the use of a model for soil analysis interpretation – a combination of bio-intensive, mineral balancing, and sound agronomic principles. Backed up by scientific literature and real-world results, this model can be adapted to a wide variety of soils and climates in mid to high rainfall areas throughout the world.
