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
