Preparation of Soil Extract
10g of garden-soil is mixed with 120 ml bidistilled water and boiled for 10 minutes. Afterwards it is centrifuged for 10 minutes (low speed), and the supernatant is filtered through a series of membrane filters from 1.2 µm – 0.1 µm pore size. The remaining filtrate is adjusted to 100 ml with bidistilled water. Aliquots of 10 ml are stored frozen. The soil should not be recently fertilized and should not contain too much humus.
