The disclosed composition for fertilization and treating trees, shrubs and climbing plants with programmed release of the active substance is comprising the active substance stored in capsules made by nanoencapsulation or microencapsulation method and wherein based on capsule membrane the time of release of the active substance is adjusted. The active component stored in the nanocapsules or microcapsules can be such that it acidifies the surrounding soil in the range of pH 2,5 to pH 6,5. One example of such active component is the use of citric acid, which is completely ecological and does not create environmental pollution. Also, the active component in the nanocapsules can be such that it regulates the acidity of the soil in the range of pH 6,5 to pH 7,0. Furthermore, the active component in the special capsules can be an insecticide and/or in the special capsules fungicide, and/or in the special capsules acaricide and/or in the special capsules pheromone and/or in the special capsules repellent.

The invention relates to a solid, particulate, homogeneous urea-based composition comprising urea in particulate form and 0.0001 to 1 weight % of a urease inhibitor of the type phosphoric triamide, in particular N-(n-butyl) thiophosphoric triamide (nBTPT), wherein the urea-based composition is further characterized in that it comprises a magnesium sulfate. The composition according to the invention has been stabilized against the degradation of a urease inhibitor of the type phosphoric triamide, in particular N-(n-butyl) thiophosphoric triamide (nBTPT) in the presence of urea. The invention further relates to a method for the manufacture of the claimed solid, particulate, homogeneous urea-based composition.

An aqueous composition comprises at least one oxidizable sulfur-based compound. A concentrated extract of the aqueous composition includes a gas chromatography/mass spectrometry-detectable amount of contaminating refinery hydrocarbons but the aqueous composition is free of refinery odor when stored for at least 24 hours at room temperature and 60% relative humidity. The aqueous compositions are prepared from a gas stream obtained from a petroleum refinery process, a coke oven, or the like, containing at least about 4 mol %, more specifically about 15 mol %, of hydrogen sulfide (H.sub.2S) and/or sulfur dioxide (SO.sub.2) and/or ammonia (NH.sub.3), and at least about 0.1 mol % of contaminating refinery hydrocarbons. The aqueous compositions are suitable for use in fertilizers, mining and industrial applications.
