The present invention relates to a method of obtaining a disaggregable granulated calcium and/or magnesium and potassium fertilizer, wherein the method comprises the steps of choosing, preparing and mixing the sources of calcium and/or magnesium and potassium, optionally the addition of chelating agents, optionally the addition of micro and/or macro nutrients, granulation and drying. The present invention further relates to a disaggregable granulated calcium and/or magnesium and potassium fertilizer.

Disclosed is a method for optimizing a particle size of slow-release nitrogen fertilizer oxamide particles for single basal fertilization, which comprises the following steps: measuring a pH value of the soil in a region; measuring an organic matter content OM of the soil, with a unit of g.kg.sup.−1; measuring a total nitrogen content TN of the soil, with a unit of g.kg.sup.−1; collecting an average temperature T at a 10 cm depth of the soil in a rice growing season in the region, with a unit of ° C.; and for a rice variety with a growth duration of D, with a unit of day, calculating a diameter of slow-release nitrogen fertilizer oxamide particles for single basal fertilization that matches a nitrogen requirement in the rice growth duration by using a formula.

The present invention relates to a fertilizer comprising at least one basic L-amino acid, such as arginine or lysine, wherein a substantial portion of the basic L-amino acid content is present as its monophosphate. The basic L-amino acid phosphate may be combined with a binder and/or provided with an outermost layer acting as a coating. The invention also relates to a method of enhancing the growth of a plant by making a basic L-amino acid phosphate available to the plant.

A method for controlling discharges of nitrogen compounds in the production of cellulose carbamate (CCA). Microcrystalline cellulose is produced from chemical pulp produced at a pulp mill, such that the chemical pulp is subjected to acid hydrolysis at an elevated temperature to form microcrystalline cellulose (MCC) and hydrolysate, and the MCC is reacted with urea to produce cellulose carbamate whereby ammonia is released. The microcrystalline cellulose production and the cellulose carbamate production are integrated into the pulp mill having a flue gas system such that carbon dioxide from the flue gases is reacted with released ammonia to produce urea, which is used in the carbamate production.

Systems, methods and apparatus for the thermal conversion of biomass into biochar. A mobile platform may be used to maneuver a mobile biochar generation system within a field of biomass. The biomass may be harvested, preprocessed and pyrolyzed. After pyrolyzation, the biochar may be cooled to a predetermined temperature by integrating water and liquid nutrients into the biochar. The system may then control the application of the infused biochar by adjusting a spreading attachment and a plowing attachment.

Provided is an emulsion in water for preventing and treating a yellow shoot of a citrus fruit tree, and it is composed of the following components according to the weight ratio: 100-300 parts of a dodecanol, 2-150 parts of a hexadecanol, 1-100 parts of a bactericidal insecticide, 5-150 parts of a plant nutrient, 5-10 parts of an emulsifier, 4-6 parts of a co-emulsifier, 40 parts of a thickener, and 500-800 parts of water. The emulsion in water for preventing and treating the yellow shoot of the citrus fruit tree, the preparation method and the application method provided by the present invention may achieve the following technical effects: the main propagation path of the citrus yellow shoot is cut off, the spread of the yellow shoot is prevented, pathogenic bacteria of the yellow shoot of the fruit tree are killed, and the vitality of a diseased tree is restored.
