A method of growing plants includes providing a calcium carbonate agricultural product including calcium carbonate to protect the plants. A method for controlling a pH of soil includes: providing a calcium carbonate agricultural product including calcium carbonate to the soil; and releasing the calcium carbonate of the calcium carbonate agricultural product to the soil.

A method of enhancing soil water infiltration (SWI) and/or reducing soil water repellency (SWR) comprising: treating an area of groundcover with a composition A comprising A1) a block polymer (P) comprising at least one polyethyleneoxide moiety and at least one polypropyleneoxide moiety, and A2) an alcohol alkoxylate (E), wherein the SWI of the area of groundcover is enhanced and/or the SWR of the area of groundcover is reduced after treatment with the composition A.

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 soil improving agent having a pellet shape and an excellent pathogenic microbe/virus eliminating ability is provided. The soil improving agent having a pellet shape includes lactic acid bacteria being live cells and a pellet-forming carrier, and the pellet-forming carrier has a volume mean diameter of 50 to 130 μm.

The present invention relates to a calcium-based bentonite and a soil-improving agent including same. More specifically, the calcium-based bentonite is characterized by including a peak at a 2θ value of 4° to 8° in an X-ray diffraction (XRD) graph.

Provided is a type of Rhizobium with the classified nomenclature of BradyRhizobium sp. KTMS 0001 or BradyRhizobium sp. KTMS 0002, and the deposit number of CCTCC No. M2017580 or CCTCC No. M2017581. Also provided are a bacterial preparation containing the Rhizobium, a method for restoring rare-earth tailings soil and a use of the Rhizobium.

A method is described for improving water retention in soil, which involves mixing a super absorbing resin (SAR) composite with the soil. The SAR composite comprises a natural pozzolan and at least one polymer or copolymer. The SAR composite may be in the form of granules having an average longest dimension of 0.2-10 mm, though the SAR composite may be pelletized or formed in other sizes. The SAR composite may release water at a faster rate in a soil when exposed to drought conditions.

The present invention provides a method of preparing a conditioner for protected agriculture acidic soil with distillers' grains and use of the conditioner. The method includes mixing distillers' grains with water, adjusting a pH to obtain adjusted distillers' grains, mixing the adjusted distillers' grains with an acid protease, and reacting under stirring at 45-50° C. for 22-26 hours to obtain a protease catalyzed substance, adjusting pH of the protease catalyzed substance, mixing with a cellulase, and reacting under stirring at 40-45° C. for 34-38 hours to obtain a cellulase catalyzed substance, filtering the cellulase catalyzed substance to obtain a filtrate, mixing the filtrate with a magnesium oxide (MgO) and then a calcium-containing substance, reacting to obtain a reactant, mixing the reactant with potassium sorbate and sucrose to obtain the conditioner for protected agriculture acidic soil.

Provided is a method of bio polymer soil additive used in both lawns, landscaping, agriculture and horticulture plant, vegetable, fruit growing operations.

This bio polymer soil additive contains a blend of zeolite organic mineral compounds and a bio-polymer compound with ion exchange, anti-bacterial and anti-viral properties to enhance plant growth and prevent plant disease.

This soil additive is used in landscaping, agricultural field and horticultural greenhouse operations to enhance plant, vegetable, and fruit production yield while reducing cost of fertilizer usage and the damaging effects of soil eutrophication on the environment.
