The invention concerns novel nitrification inhibitors.

The invention relates to the technical field of agricultural planting, in particular to a special controlled-release microbial fertilizer for peanuts in a continuous cropping field and a preparation method thereof. The fabric comprises an outer layer, a middle layer and an inner layer. Through a three-layer structure, the controlled-release fertilizer prepared by the disclosure can realize the fertilizer efficiency period of 50-60 days, and achieves the purpose of twice releases.

A method of disposing of waste material in a waste stream, including positioning a porous foamed glass member characterized by an open-cell interconnected pore network in contact with a volume of liquid to be purified and removing an amount of an undesired material from the volume of liquid.

A nanoparticulate fertilizer is provided. The fertilizer may comprise water soluble nanoparticles having a contact area to total surface area ratio greater than 1:4. The nanoparticles may have an overall positive surface charge in water. The fertilizer may be suitable for application as a seed coat. Also provided is a method of applying a seed coat, and a method of fertilizing a plant.

Disclosed herein are fluid ionized compositions, such as fluid calcium cyanamide fertilizer compositions, methods of preparation and uses thereof. In some examples, a fluid composition includes a mixture of about 40 to 20 parts of dissolved acid or acid-formed approximately neutral pH nitrogen plant nutrient compounds (such as urea ammonium nitrate and H.sub.2O) and about 1 to about 5 parts of a mixture of insoluble or weakly soluble high pH calcium-formed plant nutrient compounds (such as calcium cyanamide and H.sub.2O). The disclosed compositions and methods stabilize the compositions' contained active nutrient ions and digested carbon. The disclosed compositions and methods facilitate controllable site-directed delivery of the contents of the compositions. The compositions and methods are effective for microbes nourishment plant fertilizing, soil amending, heavy metals leaching inhibition, and digesting organic proteinaceous excreta. The compositions are stable, easily calibrated, and non-clogging for soil injection, spray and irrigation water delivery to target sites.

The present invention relates to microorganism compositions and fertilisers comprising them, which reduce soil nitrate accumulation and their use for avoiding nitrogen leaching.

In embodiments, the present invention relates to liquid formulations containing hydrophobic, biodegradable polymers disperse within a Non-aqueous Organic Solvent Delivery System (NOSDS) that is designed to coat fertilizer granules with a hydrophobic film utilizing simple application equipment such as mixers, blenders and tumblers. This film can impede the dissolution of fertilizer components by water improving fertilizer efficiency. The NOSDS can be aprotic solvents, protic solvents and mixtures of prone and aprotic solvents which are environmentally friendly, have flashpoints above 145? F. and we inherently rated safe for contact with humans and animals. The hydrophobic polymers an the reaction product of aldehyde(s) and nitrogen containing compounds.
