Particulate compositions including cores, binders, and powders are provided. Also provided are methods for producing particulate compositions, and methods for using particulate compositions.

The present invention is directed to a process for the preparation of liquid or sludge slow-release compositions suitable for agricultural use, comprising one or more active ingredients selected from the group consisting of fertilizers, pesticides, lipophilic and/or hydrophilic compounds, and mixtures of non-pathogenic bacteria together with lipophilic and/or hydrophilic compounds, wherein these actives become encapsulated in an alginate matrix. The direction also encompasses compositions prepared by this process and methods for using said compositions for the delivery and slow release of agrochemicals and other actives in close proximity to the roots of plants.

Disclosed is a spherical fertiliser granulate, which contains magnesium, sulphate and urea, each with respect to the total weight of the granulate, in the following quantities: Urea, calculated as elemental nitrogen, in a quantity of 20.0 to 38.0 wt %, magnesium, calculated as elemental magnesium, in a quantity of 1.5 to 9.5 wt % and sulphate, calculated as elemental sulphur, in a quantity of 2.7 to 12.0 wt %, wherein at least a portion of the magnesium, the urea and the sulphate is present in the form of at least one of the crystalline phases of the formulae MgSO.sub.4*6 NH.sub.2—C(═O)—NH.sub.2*0.5 H.sub.2O (I) and MgSO.sub.4*4 NH.sub.2—C(═O)—NH.sub.2*H.sub.2O (II), wherein 1 to 20 wt %, in particular 3 to 18 wt % and especially 5 to 15 wt % of the magnesium contained in the fertilizer granulate, calculated in each case as elemental magnesium, is present in the form of water-insoluble magnesium salts. Disclosed also is a process for manufacturing the fertiliser granulate as well as the use of the fertiliser granulate as fertiliser or in fertiliser mixtures.

The present invention generally relates to nitrification inhibitors and compositions comprising nitrification inhibitors. The present invention also relates to use of the nitrification inhibitors and compositions for application to fertilisers, plants, agricultural areas (e.g. soils or pastures) to reduce or inhibit the oxidation of ammonium nitrogen to nitrite and nitrate nitrogen, such as the oxidation of ammonia- or urea-based fertilisers.

A granule defined by a shape and a size, including a mass formed of a plurality of soluble fertilizer particles and a plurality of humic particles and an extended-release polymer coating surrounding an exterior surface of the mass. A process for forming the granule includes providing a mass of a plurality of soluble fertilizer particles and a plurality of humic particles and applying an extended-release coating to an exterior surface of the mass. The granule is used in a method for enhancing root growth of a target plant, such as turf grass, by applying a plurality of the granules to the target plant and allowing sufficient time for extended release of nutrients and humics from the plurality of granules.
