The present invention relates to the use of foaming additives in liquid, paste or powder form, to condition soil excavated with a tunnel boring machine. Said additives can be classified as readily biodegradable and are characterised by a lower ecotoxicological impact than commercial products.

The present disclosure relates to a composition for improve the soil fertility and it's application as irrigation which decomposes plant roots, undecomposed material thereby increase the organic carbon as well all nutrient to the plant. The agricultural composition comprising jaggery and liquid waste decompose. The agricultural composition of the present disclosure can be used for improving soil condition and promoting plant growth.

The present invention relates to the technical field of fertilizer and soil conditioner production, and particularly to a regulating solution, fertilizer and soil conditioner for increasing Vitamin C (abbreviated as Vc, which is also known as ascorbic acid) content of plants as well as a preparation method therefor and application thereof. At the same time, the present invention also relates to a resource utilization technique of wasted liquid in the industrial production of vitamin C. The regulating solution is obtained by regulating the pH value of a wasted gulonic acid mother solution (a residue after evaporation of fermentation liquid from vitamin C industry) or/and 2-keto-L-gulonic acid solution by an alkaline solution, wherein a fertilizer regulating solution is obtained by regulating the pH value of the regulating solution to 3.0-9.0; and a soil conditioner regulating solution is obtained by regulating the pH value of the regulating solution to 2.0-10.0. The regulating solution obtained by the present invention and the fertilizer and soil conditioner prepared by using the regulating solution as a raw material can significantly increase Vc content of plants, and the effect can be found in all plants tested.
