A.

Is compost the same as fertilizer?

The simplest way to distinguish between compost and fertilizer is to remember this: Compost feeds the soil and fertilizer feeds the plants. Fertilizer adds to the soil's nutrient supply, but instead of feeding the soil food web, the ingredients in fertilizers are intended to meet the needs of fast-growing plants.
  • Can you replace fertilizer with compost?

    No, you can not replace 'fertilizer' with compost. You do have to consider the amount of necessary chemicals available and what chemicals your particular compost adds. Fertilizing includes not only the 3 biggies; Nitrogen, Phosphorus and Potassium but at least a dozen micro nutrients as well.
  • Can you add fertilizer to a compost pile?

    Then add a nitrogen source, such as ammonium nitrate, ammonium sulfate, or an inexpensive high nitrogen lawn fertilizer without herbicide. You may choose to add a one-inch layer of soil or completed compost over the nitrogen to increase the number of decomposing microbes in the pile.
  • Is mulch and compost the same thing?

    Compost is full of nutrients that we want to get down in the soil to feed the plants through their roots. In contrast, mulch is the layer of organic materials placed on the top of the soil as a protective cover. Mulch helps to suppress weed germination, retain moisture, insulate the soil, and reduce erosion.
B.

When should you put compost on your garden?

Some people recommend late fall as a good time to spread compost over a garden bed, and cover it with a winter mulch, such as chopped leaves. By spring, soil organisms will have worked the compost into the soil. Others recommend spreading compost two weeks before planting time in the spring.
