Provided herein is technology relating to organic fertilizers and particularly, but not exclusively, to organic and/or biodegradable flocculants, methods of preparing organic fertilizers using an organic and/or biodegradable flocculant, and systems for treating water using an organic and/or biodegradable flocculant to prepare an organic fertilizer.

The present disclosure relates to an article for enriching soil fertility, a method of manufacturing the same and a method of enriching soil fertility. The article comprising: a plurality of containers, each having a respective fluid-permeable membrane and each containing one or more fertilizers. At least one of permeabilities of the membranes and contents of the one or more fertilizers are selected to control a release of the fertilizers from the containers.

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.

A granule includes (i) particles comprising an active agent and (ii) a binding agent comprising a lignosulfonate and a mixture of polyols. A ratio of lignosulfonate to the mixture of polyols is in the range of 1.5:1 to 16:1. The mixture of polyols may include monosaccharides, disaccharides, hydrogenated starch hydrolysates, or combinations thereof. The active agent may be an agriculturally active agent, a pharmaceutically active agent, or a food product. The granule may have a sphericity of at least 85%.

In accordance with the present invention, disclosed herein is a fertilizer core and fertilizer granule and methods related thereto. The fertilizer core particle has an outer surface and comprising one or more fertilizer additives, one or more binders, and one or more pH buffering agents, and wherein the fertilizer core particle comprises from about 10 wt % to about 99 wt % of the one or more binders.

The present invention relates to methods and compositions for a fertilizer pouch comprised of hot water soluble polyvinyl alcohol. Methods and compositions for reducing leached nutrients are also provided including but not limited to: Iron, Manganese, Copper, Bicarbonate, Zinc, Phosphorus, Molybdenum, Ammonia, Nitrogen, Calcium, Potassium, Sulfate, Magnesium, Sodium, Chloride, Inorganic Nitrogen, and Total Nitrogen. Further, methods and compositions for treating a plant are provided.

There is provided an apparatus for extraction of at least one object from a cavity. The apparatus includes a sleeve including an inflatable section configured to surround the at least one object during inflation; a handle configured to enable a user to hold the sleeve, the handle defining a holding edge of an opening at a first portion of the sleeve; and a handle-mount mounted to a peripheral area around the opening, the handle-mount being for attachment of a pump used for inflating the inflatable section. There is also provided a pressure limitation apparatus configured to operate with a birth assistance device when attached via a conduit.

Methods and related systems for conditioning of granular fertilizers post-manufacture to reduce the generation of dust during handling, transport, and storage of the fertilizers, and/or to increase the agricultural benefits of the fertilizer. The method includes introducing a quantity of an aqueous conditioning agent, such as by spraying, to a plurality of fertilizer granules. The aqueous conditioning agent can include one or more beneficial agricultural and/or dedusting additives including one or more acidifying agents, one or more drying agents, one or more herbicides and/or pesticides, one or more chelating agents, one or more biological agents, and combinations thereof.

There is provided a fertilizer pouch for planting on or in soil. The fertilizer pouch comprises an enclosed biodegradable container having sidewalls surrounding an interior space and fertilizer situated within the interior space. Upon planting, the biodegradable container degrades and releases the fertilizer therein into the surrounding soil. There is also provided a method of applying fertilizer to soil, the method comprises planting one or more of the above fertilizer pouches in or on the soil, wherein the biodegradable containers degrade at different rates, thus releasing the fertilizer therein into the surrounding soil at different times.

Provided herein is technology relating to organic fertilizers and particularly, but not exclusively, to organic and/or biodegradable flocculants, methods of preparing organic fertilizers using an organic and/or biodegradable flocculant, and systems for treating water using an organic and/or biodegradable flocculant to prepare an organic fertilizer.
