Additives may also be incorporated into a dry and coarse soil type to help its water retention ability. A moist type of soil helps plants grow stronger because it allows plant roots to extend deeper while growing thicker and healthier. In addition, it also encourages microbial growth and supports nutrient absorption.

You can also use Comfrey leaves as a liner for planting holes and containers where they can slowly decompose and release nutrients helping to amend potting soil.
Vermicompost or worm castings are the byproduct of the decomposition process of worms. It contains water-soluble nutrients and is an excellent, nutrient-rich organic fertilizer and soil conditioner. It is used in farming as well as small scale sustainable, organic farming.

A little goes a long way with this soil additive. You can mix it into the soil in the fall or at least two weeks before planting to let the nutrients seep into the soil.
Wood ash contains significant amounts of potassium and calcium while providing smaller amounts of phosphorous and magnesium. It also delivers micro-nutrients like zinc and copper.
It also contains a significant amount of calcium, the primary substitute for lime to increase the pH of acidic soils. Wood ash is a natural substitute for lime to help maintain proper soil pH, especially for acidic soil amendments.
