Research has shown that earthworm excrement, also called castings or vermicompost, improves aeration, porosity, structure, drainage, and moisture-holding capacity of soil.
Many studies prove that when compared to conventional composts, vermicompost is less variable and much more stable. Mixing vermicompost into planting medium essentially eliminated need for additional fertilizer in production of tomato plugs as one example.
Studies show that earthworm castings increase height, stem diameter, enhance root growth, increase dry weight, and produce more flowers per plant than peat moss.
Redworm castings are richest and purest humus matter in world. Humus is believed to aid in prevention of harmful plant pathogens, fungi, nematodes and bacteria.
