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 producing an amino acid liquid fertilizer from waste feathers includes: acquiring an enzymatic hydrolysate by performing enzymolysis on feather powder with a complex enzyme; adding acid protease to the enzymatic hydrolysate for enzymolysis; and acquiring the amino acid liquid fertilizer by performing enzyme inactivation on a filtrate acquired by performing filtering after enzymolysis is completed, wherein the complex enzyme includes keratinase and amino acid peptidase. By adopting this method, the enzymolysis rate of the feathers reaches 80% or above and the prepared amino acid liquid fertilizer contains various kinds of amino acids (17 amino acids); and the content of the amino acid can reach 10.12% (by mass fraction) or above and the content of small peptide reaches 9.39% (by mass fraction), which reach the Chinese standard of the amino acid liquid fertilizers without concentration. Thus, the environmental-friendly amino acid liquid fertilizer can be prepared.

A biostimulant concentrate includes purified water and a solubilizer, triacontanol, and an array of brassinosteroids selected from the group consisting of brassinolide, brassinone, dolicholide, homobrassinolide, and combinations thereof. The triacontanol is concentrated as a 95% concentrate that is included in an amount of 2-15 grains per liter of biostimulant concentrate. In one embodiment, 3 grams of triacontanol 95% is used per liter of biostimulant concentrate. The biostimulant is formulated into a foliar spray in one embodiment of the invention. The present inventive formulation is used as an in-furrow application, which is mixed with fertilizer in one aspect of the invention. The present invention is mixed with herbicide and broadcast sprayed in another embodiment of the invention. This broadcast spray can be performed either pre-emergence, or post emergence, or both.

A protein product capable of immobilizing a target and being cleared as required includes a protein (lysozyme, bovine serum albumin (BSA), whey albumin, insulin, α-lactalbumin, fibrinogen, ribonuclease A, cytochrome c, α-amylase, horseradish peroxidase (HRP), pepsin, myoglobin, collagen, keratin, or the like), a protein modifier (a strong oxidizing agent or a strong reducing agent), and a matter to be immobilized (a coating, a pesticide, a chemical fertilizer, a cosmetic, a medical drug, or the like). A protein film can be generated through the phase transition of the protein to immobilize the matter to be immobilized on a target surface, thereby improving the utilization rate of the matter to be immobilized and reducing the resource waste and environmental pollution caused by the loss of the matter to be immobilized. In addition, after the protein film is decomposed, the matter to be immobilized will also be effectively cleared.

The present invention is a plant growth promoter containing a lignocellulosic biomass, wherein the lignocellulosic biomass has a lignin content of 40% by mass or more and 60% by mass or less and a contact angle with water of 50° or less.
