We then put these also into three other tulgren funnels. By then it was lunch time and we all ate together. After lunch I weighed the soil samples and got to see the organisms that were in the beaker under the tulgren funnel. At 3.30 p.m I left for home. 11th November: In the morning, I was given two types of earthworms i.e. Lampito mauritii and Perionyx excavatus and told to observe them.
The most suitable earthworms recommended for vermiculture are the epigeic and anecic earthworms. Perionyx excavatus is purplish red and rough. Near the two ends the Perionyx excavatus is almost black in colour. They also breed faster than Lampito mauritii. Earthworms prefer cool temperatures, moist soil, humidity, relatively less sunlight and neither too coarse nor too fine sand.
Then, a half to one inch layer of sand should be spread. Over that, a five to six inch layer of soil should be spread. Then Lampito mauritii and Perionyx excavatus earthworms should be introduced. The soil must then be moistened with water. This is called a vermibed. The cowdung and hay will allow the worms to multiply.
