Good soil management is fundamental to vine health and grape quality. The ability of soil to function properly and support plant growth is determined by its physical, biological and chemical status. Conservation of the soil and soil organic matter helps ensure soil stability, reduces erosion, maintains good soil structure, promotes drainage and aeration, and supports microbial and macrobial life. Healthy soil will support microbes vital to the:

• Breakdown of organic matter and release of nutrients into plant available forms
• Suppression of soil-borne diseases
• Maintenance and improvement of soil structure
• Degradation of chemical compounds

The physical structure, pH and chemistry of soil will also affect root system development and the supply of water and minerals to the vine. Properly managed soil will reduce reliance on agrochemicals and allow the long-term maintenance of fertile soil.
