Organic fertilizers, Bio-stimulants, and biologicals in that order.

To reduce confusion we’ve listed the types of products to the left from least biological to most biological. The hope is that this will show you the steps to building soil biology like trichoderma, mycorrhizae and rhizobacteria.

So let’s look at some situations you might run into.

  • New construction/new landscaping – These are usually very damaged soils. Construction has greatly degraded the natural soil biology.
    • Compost or manure
    • Humic acids
    • Biological soil amendments
  • Planting in existing soils – Soils that have been in production for some time have built up some natural soil biology. However a boost of biology in the planting hole is a great idea.
    • Manure based fertilizers
    • Biological soil amendments
  • Plants in decline – Top dressing with added biology and additional ingredients to help boost plant health.
    • Humic acids
    • Manure based fertilizers
    • Biological soil amendments
  • Sodding – Sod from the sod farm is very low in biology. They have applied copious amounts of fungicides and herbicides which has an adverse effect on soil biology.
    • Compost
    • Biological soil amendments

It’s a step by step process. Soils in nature, when they are damages by fire, mud slide, or flood, follow a transition during the re-growing process. Weed seeds and animal feet bring in hardy plants that can grow in damaged soils. These are called pioneer species. They can start to die and decompose to add organic matter to the soil. Gradually these pioneer plants introduce biology which in turn allows later generations of grasses, shrubs, and trees to grow. By knowing what types of organic and biological fertilizers to use, and at what time, can speed up the establishment process of your next project.
