A method for producing soil amendment is disclosed. The method comprising: In the first step, different parts of a mesquite tree are collected. The collected parts comprises leaves, trunk, beans, mistletoe, roots and branches. In the second step, the collected parts are organized based on nutrient level. In the third step, the collected parts are dried. In the fourth step, the dried parts are milled to obtain a powder material of desired size. The powder material obtained is applied to a soil to improve the physical constitution of the soil.

A heavy metal cadmium deactivator for activating the activity of sulfur-reducing bacteria in rice field soil, and an application thereof. The deactivator is constituted by electron shuttles alone or electron shuttles and electron donors, but cannot be constituted by electron donors alone. The mass ratio of the electron donors to the electron shuttles is (1:3)-(1:8). Also, a heavy metal cadmium deactivating method for activating the activity of microorganisms in rice field soil, such as sulfur-reducing bacteria. By applying the functional deactivator to rice field soil, the activity of microorganisms, such as sulfur-reducing bacteria, can be activated, thereby accelerating the reduction process of sulfur and iron in soil to facilitate the fixation of cadmium; cadmium adsorption and accumulation in rice is reduced to achieve secure production in fields moderately or lightly polluted by cadmium.

A coal gangue-based ecological restoration material, and a preparation method and an application thereof are provided. The coal gangue-based ecological restoration material is made from the following raw materials in parts by weight: 10 parts by weight of coal gangue; 0.5-1 parts by weight of an adhesive; 1-10 parts by weight of a plant fiber; and 1 part by weight of a fertilizer. The preparation method of the coal gangue-based ecological restoration material includes: primary crushing, primary heat treatment, primary cooling, secondary crushing, mixing and molding, secondary heat treatment, secondary cooling, mixing, and cooling and molding. The method uses the coal gangue as a main raw material to prepare the ecological restoration material, which can realize the effective utilization of the coal gangue and has good environmental protection, economic and social benefits.

A nitrogen stabilizing composition is provided. The composition includes 22 to 26% w/w N-(n-butyl) thiophosphoric triamide (NBPT), 4 to 8% w/w of 3,4-dimethyl pyrazole phosphate (DMPP) and/or nitrapyrin, a solvent including N-methyl-2-pyrrolidone (NMP) and propylene glycol, 0.1 to 5% w/w vegetable oil, and 0.1 to 5% w/w lecithin.

In some embodiments, there may be provided a luminescent material or a persistent luminescent (PersL) material that is used to redistribute sunlight. Related systems, methods, and articles of manufacture are also disclosed.

A biological water retention material, a method for preparing the same and a use thereof. A Bacillus subtilis, named as Bacillus subtilis GE1, which has been deposited in China General Microbiological Culture Collection, Institute of Microbiology, Chinese Academy of Sciences on Jan. 7, 2016, with a deposit number of CGMCC No. 11964, solves the problem of lacking a biological water retention material that fully combines water retention materials with microbial agents to increase the survival rate of silviculture under drought conditions by increasing soil moisture content as well as enhancing the drought resistance of plants. It is suitable for use under drought and water shortage conditions, and can fully utilize the coupling effect of water retention and bacterial agents, increasing the survival rate of silviculture under drought conditions and promoting seedling growth by increasing soil moisture content as well as enhancing the drought resistance of plants.

The invention relates to a ground cover in the form of a mulch, comprising a paper substrate originating from fibre-bearing pulp, preferably emanating from lignocellulosic material, which has been web-formed or sheet-formed. Paper based mulches face problems with biodegradability and microbial attacks, mechanical strength and cost. The solution according to the invention is that the fibres have been coated with one or more minerals, e.g., calcium carbonate, and the mulch comprises one or more functional agents, e.g., a colorant. Further, the mineral coated onto or into the fibres predominantly show up when precipitated in the form of one or more metal carbonates.

A method for preparing an iron silicon sulfur multi-element composite biochar soil heavy metal conditioner, including: adding silicate to agricultural wastes and roasting with air isolated to enable silicate to enter structural pores of biochar; enabling iron-containing slats to gather on kaolinite with a given proportion; enabling sulfate to gather on bentonite with a given proportion; mixing the above three materials evenly according to a given proportion; and adding diatomite and starch to the mixture, and pelleting to prepare the iron silicon sulfur multi-element composite biochar soil heavy metal conditioner. The conditioner can be widely applied in soil heavy metal pollution abatement of rice fields, and it is able to synchronously passivate composite pollutants in acid or alkaline soils to reduce the amount of pollutants absorbed by and accumulated in rice, thereby achieving safe utilization of polluted farmland.
