A compatible combination of micron size carbon based particles along with beneficial microbial species and conventional plant nutrients into a plant or an animal food. This balanced product is a combination of nutrients and microbes, and can be applied as a suspension in water or as a slow release granule. This combination of organic plant food and fertilizer can also be applied as a foliar, as a seed coating, and as an all-in-one granule combination of nutrients and biological agents, to facilitate mineralization, nutrient availability and provide energy to the soil and plants, with a total conversion of a storable processed biomass into a precisely known quality and quantity of usable fertilizer tea solution, with no biomass waste, odors, or crop application timing problems. The process of formulating the combination product reduces green house gas emissions by limiting mineralization and composting.

This disclosure relates to water-absorbing and slow/controlled release fertilizer, in particular to a water-absorbing and water-retaining multi-nutrient biodegradable polymeric slow/controlled release fertilizer having a semi-interpenetrating network structure, and preparation methods thereof. The method can comprises the steps of: reacting formaldehyde with urea to obtain a hydroxymethyl urea solution; adding acrylic acid and acrylamide monomers into another reactor, and adding a KOH solution to adjust the neutralization degree of acrylic acid, then adding one of inorganic clay, pretreated crop straw or cellulose, then adding initiator, monopotassium phosphate and the prepared hydroxymethyl urea solution sequentially; allowing to react at temperature after being mixed uniformly to obtain a viscous product; and granulating the viscous product and oven drying the same to obtain the fertilizer. The fertilizer prepared according to the present invention has strong water-absorbing and water-retaining capacity, and an excellent slow release performance for nitrogen, phosphorus and potassium contained as nutrients.

Fertilizer granules containing elemental sulfur and a hydrogel which expands or swells in the soil to more readily disperse the elemental sulfur surface throughout the soil, which increases the elemental sulfur surface area available for oxidation, and ultimately uptake of sulfur by the plant. The elemental sulfur and hydrogel can be added to a fertilizer composition as either an exterior coating or co-granulated with the base fertilizer composition.
