A fertilizer granule containing a core containing a nitrogen containing fertilizer such as urea and a coat on the core, the coat containing an organic zinc (Zn) complex and an inorganic Zn compound, and methods of making and using the fertilizer granule.

The present invention relates to fertilizer particles encapsulated in modified chitosan and a method of obtaining them. The particles described in this invention allow a controlled, moderate, or gradual release of an active material from a reserve substrate to another medium, in order to increase the effectiveness of the active material by prolonging its action over time. This invention is characterized in that the active components of said formulations are capable of causing a synergistic effect, considerably increasing the growth and development of plants.

The present disclosure belongs to the technical field of ecological environmental protection, resource development and utilization and new materials, and particularly relates to a method and device for rapidly forming artificial clay and artificial organic ecological mud. The method comprises the following steps: raw material and water storage preparation; preparing nutrient aqueous solution; preparing mineral muddy water; preparing flocculent mineral solution; and reacting and dehydrating to form artificial clay or artificial organic ecological mud. The device comprises a grinding mill, a feeding system, a silo, a belt conveyor, an agitator, a dehydration system and a reservoir. In accordance with the present disclosure, the formation period of natural clay is greatly shortened by artificial means, making the clay become a renewable resource.

A growth medium for fungus is obtained by: (a) treating a mixture of lignocellulosic biomass and water with at least one oxidizing agent and steam at a temperature in a range of from about 130° C. to about 220° C. for a period from about 5 seconds to about 10 hours; (b) periodically measuring a pH of the mixture for substantially an entire duration of the treating step; and (c) as necessary, based on the pH of the mixture measured in step (b), adjusting the pH of the mixture into a range of from about pH 4.5 to about pH 7.5 by adding a base to the mixture. A method for producing the growth medium for fungi and a method for cultivating fungi are also provided.
