The focus in recent years on soil health has resulted in more research on the microbiome of vineyards and the importance of maintaining the diversity, vigor, and nutrients that soil micro-organisms require to benefit vine growth and berry quality.
Using soil health conditioning and nutrition technologies can assure that vines are growing in balanced, complex microbial soils for more robust root growth, more effective leaf area development, and stronger, more efficient vascular systems. These are the foundations for more effective nutrient uptake, photosynthesis, and translocation of minerals, water, and other building blocks of healthy vines. Vines growing in healthy soils are better able to tolerate the inevitable stresses of the growing season to produce more abundant, higher-quality harvests.
Many university and USDA papers on soil health are geared to row crop farms, not vineyards. But there are some organizations and papers that do pertain to vineyards, and others contain informative background information on basic soil microbiology. Following are some titles and links to articles and sites that may be helpful.
One of the leading researchers in vineyard soil health is Belinda Rawnsley, a researcher at the South Australia Research and Development Institute, whose award-winning project provides information on soil biology tests that are cost effective. Her presentations include vineyard practices that impact soil organisms.
