Worm Cast Fertilizer VS Chemical Fertilizer

Composition & Function

Worm Cast Fertilizer

Chemical Fertilizer

Soil Health

rich in humus, which improves soil aggregation
Digestive process in worms makes the nutrients in their castings more readily available to plants.
Increase drought resistance.


Micro Nutrients

Contain of most micro nutrients : baron, calcium, copper, chlorine, magnesium, molybdenum, iron, zinc Non unless added


Balanced and enhance the soil pH Disrupt the soil pH, over application can render the soil very low or high pH

Organic Matters

High in Organic Matters with lots of nutrient and moisture-holding capacity.
Foster growth of soil organisms, and promote healthier plant roots development.
Do not have sufficient organic matters that is essential for plant growth.

Moisture Absorption Capabilities

Absorbs about 90% its own weight and helps soil retain moisture for plant use.

Decrease soil moisture due to stiffening the soil.
Effect of compacting affected the level of moisture absorption and retention in the soil.

Effects on soil

Allowing the soil to absorb and retain moisture by balancing, aeration and rejuvenates the soil. The chemical fertilizers do not build soil and can build up to toxic proportions after continued use.

Beneficial Bacteria

Beneficial Microbes are in abundance contributing good aerated fertile soil Decrease or eliminate Beneficial Bacterial growth.

Nutrient Absorption Abilities

Enhance plant moisture uptake including absorption of nutrients and micro nutrients Fertilizer has to be applied very frequently since soil does not allow water absorption hence does not release nutrients to the plants.
