摘要:
The invention provides a fertiliser composition P, K, N, NP, PK, NK or NPK that includes an extract of Enterobacter xiangfangensis, strain CECT 9264, and niacin as a bacterial growth stimulator, in addition to a source of carbon and micronutrients.
摘要:
The invention provides a procedure for obtaining humic acids extracted from leonardites which have greater capacity to form complexes with metal ions, said procedure including selective activation, extraction and purification that increases the capacity of the complex-forming functional groups present in humic acids to form complexes with said metal ions. The procedure of the invention essentially includes a first molturation stage in leonardite liquid and two extraction stages based on a basic pH gradient.
摘要:
The present invention provides a fertiliser composition comprising struvite and syringic acid as an enhancer of the biological solubilisation of struvite, wherein the syringic acid in combination with struvite improves phosphorus and magnesium levels in plants, its application constituting an alternative to conventional fertilisers based on phosphorus and/or magnesium.
摘要:
The present invention provides a fertiliser composition comprising trigonelline as an enhancer of the microbiological oxidation of elemental sulphur to sulphate ion (S 0 to SO 4 2- ) where trigonelline increases SO 4 2- levels in agricultural soils.
摘要:
The invention provides an additive for fodder for animal nutrition, for example feedlot cattle or poultry, which includes a phytase enzyme and a calcium phosphate source in a single additive.
摘要:
The invention relates to a method for the treatment of organic animal waste, manure and slurry, in particular of housed animals on livestock farms, as well as the use of the product obtained by means of said treatment as a liquid fertiliser applied directly to crops via irrigation, wherein the method comprises the steps of crushing, sonication and balancing of the C:N ratio.
摘要:
The invention provides a foliar fertiliser that includes an extract of methylotrophic microorganisms obtained from a first initial process of fermenting live methylotrophic microorganisms using methanol as the only source of carbon or energy and a second process that includes the stages of cell disruption by physical, chemical or enzymatic methods, separating the soluble parts from the insoluble parts by means of tangential filtration or centrifugation and, optionally, concentrating by means of filtration or atomisation.
摘要:
The invention provides a method for stabilising biogenic polyamines, said biogenic polyamines being attached to galactomannans to increase the stability thereof in soil, organic soil conditioners or fertiliser compositions, thereby facilitating a concentration of these biogenic polyamines that is more stable against degradation over time.
摘要:
The invention provides a method for the industrial manufacture of granulated fertilisers of the type including the steps of granulation, drying, control of the granule temperature, and sifting, granulation being carried out using a starting material in the form of a thick homogenized suspension in which soluble and insoluble components are present, and in which, prior to the granulation step, said starting material is premixed with other selected raw materials with a high content of nitrogen, phosphorus, potassium, sulfur, calcium, organic matter, micronutrients and combinations thereof.
摘要:
The invention provides a solid state biological fermentation process wherein an animal waste feedstock with a high protein nitrogen content is transformed into a final product of high value for various industrial processes, such as the fertiliser, composting industry and the like. The process essentially comprises selecting those microorganisms present in the animal waste feedstock that have the capacity to transform organic nitrogen into protein nitrogen, i.e., into amino acids and peptides, culturing said microorganisms in a suitable medium and adding said microorganisms in the optimal culture medium thereof to the previously sterilised or inactivated feedstock.
