A lubricated agricultural mixture and method(s) of use thereof is described. Embodiments of the lubricated agricultural mixture can include a carbon source, a fertilizer, a binder, and a hydrogel. The lubricated agricultural mixture can be formed into tablets, granules, and wafers. The different forms of the lubricated agricultural mixture can be implemented in various situations. For instance, the table form can be distributed via machinery such that the carbon source acts as a lubricant for the machinery to minimize wear on the machinery.

The present application relates to an iron impregnated biochar and its use as a fertilizer. The iron impregnated biochar of the present application has a ratio of iron (III) to iron (II) ranging from 5:1 to 10:1. The biochar may be produced by a method including treating the biomass with an iron (II) ion solution, pyrolyzing the iron (II)-treated biomass in an oxidative environment and recovering the biochar product from the pyrolyzed iron (II)-treated biomass.

A slow release fertilizer composition includes particles of a nitrogen fertilizer coated with at least one layer having at least one polyhydroxyalkanoate (PHA), the at least one layer having an average thickness between 1 μm and 200 μm. The relative production process is also described. The slow release fertilizer composition provides for the use of biodegradable and biocompatible materials that allow a slow release of the fertilizer in the culture medium, according to the current regulations, without causing the accumulation of products which are harmful for the environment.

In one aspect, a multi-layered fertilizer includes a layer-by-layer coated fertilizer layer and a coating layer, wherein the fertilizer layer is separated from the coating layer, and one of the fertilizer layers is a fertilizer core; the fertilizer layer contains at least one of nitrogen fertilizer, phosphate fertilizer and potassium fertilizer, the coating layer is polyurea formaldehyde, which includes at least a polyurea formaldehyde having two to five carbon atoms. It can better control the release of nitrogen, phosphorus, potassium, calcium, magnesium and zinc in the fertilizer to meet the different nutrient requirements of different crops at different growth stages. The fertilizer can be prepared by a reactor, a slurry tank, a powdering tank and supporting facilities, which can control the amount of each layer of fertilizer and its position in the entire fertilizer granules according to a design procedure.
