Soil Organic Matter

Soil organic matter helps maintain soil structure, enhances soil moisture holding capacity, increases the ability of the soil to hold nutrients and improves drainage. Adequate soil organic matter levels can help maintain crop yields and long-term plant health, especially in adverse weather conditions. Many horticultural soils are light-textured and frequently cultivated. The maintenance of organic matter levels in these soils is a challenge.

To ensure long-term productivity of fruit crops, assess the soil quality of each field before planting and take steps to maintain or improve it. For more information, see OMAFRA Publication 611, Soil Fertility Handbook. and Table 3-5. Optimum Soil Organic Matter Contents for a Range of Soil Types.
