The Importance of Sustainable Soil Management

Your garden harvest starts with healthy soil. How much produce you get, whether your plants are affected by disease, and even how many pests you have can be affected by how you treat your soil. But how you manage your soil can also affect wildlife and the environment.

Algal Blooms

On this blog, we’ve frequently discussed the importance of mulch and cover crops. They are two simple ways to help prevent soil erosion and nutrient runoff. While these effects are obviously bad for your garden they also have more far-reaching consequences. When soil and nutrients erode they contribute to algal blooms in streams, lakes, rivers, and eventually the ocean. 

Algal blooms can be green, red, blue, or brown. They affect both marine and freshwater environments and produce toxins that have a variety of negative effects. The toxins can sicken or kill people and animals, create dead zones in the water, raise treatment costs for drinking water, and hurt industries that depend on clean water. One way we can prevent these algal blooms is to practice good soil management.

Good Soil Practices

Sustainable soil management means using practices that build healthy soil, reduce erosion, and reduce the need for fertilizer, pesticides, and herbicides. They include:

  • Planting cover crops, especially in the fall to prevent erosion and add nutrients and organic matter to the soil.
  • Using mulch around plants whenever possible to prevent erosion, suppress weeds, hold moisture, and add nutrients and organic matter to the soil.  
  • Rotating crops to disrupt disease and pest life cycles and reduce excess nutrients.
  • Reducing soil compaction which helps fungal and insect life in soil thrive. Whenever possible reduce tilling and using equipment. 
  • Providing habitat for beneficial insects like cover crops, mulch, wildflower patches, and insect hotels.

While small gardeners and farmers are not the biggest contributors to this type of pollution every little bit helps. Making these small changes can improve your garden, improve water quality, and help wildlife.
