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