Hollow nanoparticles for time-release delivery of a payload. A composition include a mesoporous hollow nanoparticle and a degradation agent, wherein the degradation agent includes one or more of a reducing agent, an acid, or an acidifier. The mesoporous hollow nanoparticle degrades in a presence of the degradation agent for time-release of a payload.

A process is provided to produce a micronized sulphur powder product, including the preparation of a micronized sulphur emulsion from molten sulphur and a dispersant solution, including a surfactant in a concentration less than the critical micelle concentration of the surfactant.

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.

A process for making a potassium humate zinc sulfate compound, the process including: obtaining a plurality of fully-soluble potassium humate powder particles; obtaining a zinc sulfate compound; and mixing the plurality of potassium humate particles with the zinc sulfate compound, thereby forming a homogenized mixture, thereby forming a potassium humate zinc sulfate compound configured to be applied to a soil surface.

The invention relates to a particulate urea-based composition comprising elemental sulphur and a urease inhibitor of the type phosphoric triamide, wherein the urea-based composition comprising elemental sulphur is further characterized in that it comprises a magnesium sulphate. The composition according to the invention has improved properties for reducing ammonia loss by urease activity in the soil and is in particular suitable as a fertilizer. The invention further relates to a method for the manufacture of a particulate urea-based composition comprising urea, elemental sulphur and a urease inhibitor of the type phosphoric triamide, in particular N-(n-butyl) thiophosphoric triamide (nBTPT), as well as to a composition of kit of parts comprising a magnesium sulphate.

Described is a hydroponic system wherein a feed formulation comprising a plant's nutritionally effective amount of at least one amino acid, which upon uptake, becomes a substantial source of nitrogen for said plant, is applied to the foliage of the plant, and the roots of the plant are in contact with an incomplete water solution that comprises less than the plant's nutritional nitrogen requirements. The feed formulation, methods of feeding a plant or plant seed, and plants produced thereby are also described.
