The liquid contains an evaporative solvent, light-absorbing and bonding agents, also one forming a casting mould. The latter agent can be material evaporating on contact with air such as albumen, particularly of animal origin. The liquid can be prepared by combining water, natura fibre, carbon, animal albumens and potassium water-glass in respective percentages by weight of 25-92.9, 1-10, 0.1-1 and 5-50. After weeding the surface to be used, the liquid can be applied round the plants to be grown, typically using an auger-type pump. |
