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.

A system for coating fertilizer substrates is provided. The system comprises a mixing unit wherein the mixing unit comprises a container bowl having an inlet portion and an outlet portion wherein the inlet portion is operatively fastened to a hot air conduit having a blowing unit connected at one end. The invention also relates to a process for coating fertilizer substrates and the coated substrates thereof.

The present invention concerns the use of an inoculum of at least one strain of Penicillium brasilianum for improving plant growth conditions. It also concerns a method of increasing the availability of phosphorus and/or micronutrients for plant uptake from a plant growth substrate, said method comprising applying to the plant growth substrate an effective amount of an inoculum of Penicillium brasilianum.
