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.

A bacterial product may comprise strains Azospirillum oryzae AO.sub.512, Azospirillum lipoferum AL.sub.20, Pantoea dispersa PD.sub.2, Bacillus subtilis TU.sub.2, Lysinibacillus sphaericus 3S and Paenibacillus polymyxa SR.sub.17, in a total minimal concentration of 10.sup.8 CFU/g (Colony forming Units). These bacteria may be attached to an insoluble granular carrier formed of a mixture of natural clays and minerals. This formulation may preserve the viability of the microorganism for a long time while in storage, as well as after its application on the field. These microorganisms, as PGPR, may be capable of fixing atmospheric nitrogen, solubilize phosphates, potassium, as well as other minerals immobilized in the soil, which allows for a drastic reduction, and even for a complete elimination, of conventional fertilization methods. These bacteria are not harmful in any sense neither to human beings nor the environment.

The present invention concerns a process for preparing a composite of porous material/compound/hybrid organic-inorganic material having a 2:1 lamellar structure, said hybrid material having the following general formula I:
Na.sub.x[(Mg.sub.3)(Al.sub.x(RSi).sub.4−x)O.sub.8+x(OH).sub.2]  (I)
wherein
x is a number such that 0≤x<1.2 and
R represents a C.sub.1-C.sub.30 alkyl group, an aryl group, a (C.sub.1-C.sub.30 alkyl)aryl group or an O—(C.sub.1-C.sub.30 alkyl) group, it being possible for the alkyl group to be substituted with a group chosen from a phenyl, vinyl, aminopropyl or mercaptopropyl group,
and said compound being chosen from the group constituted of at least one active substance and at least one microorganism and mixtures thereof the process comprising:
a) the step of sol-gel synthesis of the hybrid organic-inorganic material having a 2:1 lamellar structure in the presence of the compound and of the porous material saturated with the compound;
b) the recovery of the composite. It also concerns a composite obtainable by means of this process, a composition comprising it and its use in particular for the fertilization of plants.

The present disclosure describes a composition including a sulfopolymer, and one or more agrochemicals. The composition exhibits increased rainfastness as compared to the same composition without the sulfopolymer. The present disclosure also describes methods of making and using such emulsion formulations in agriculture.

A preparation method of charcoal-based fertilizer is provided. Particularly, a special pig manure charcoal modified by amino grafting, a preparation method thereof, and its application in the reuse of nitrogen from farmland drainage are provided. The preparation method includes the following steps: 1) drying raw pig manure to a moisture content of 80%-85% and carrying out pickling, drying, and crushing successively to obtain a dried pig manure powder; 2) conducting liquid nitrogen pretreatment and high-temperature charcoalization to obtain an expanded pig manure charcoal; 3) performing carboxylation treatment to obtain a carboxylated pig manure charcoal; 4) amino grafting: adding an ammonia liquor to the carboxylated pig manure charcoal obtained in step 3), stirring for 20-24 h in an oil bath at 200-240° C.; washing and filtering; and drying and grinding to obtain the special pig manure charcoal modified by amino grafting.

A use of 1,9-decanediol in retarding urea hydrolysis in soil is provided. It is found that 1,9-decanediol has a dual regulatory effect, which can not only inhibit the nitrification process, but also retard urea hydrolysis and reduce the transformation of urea to other nitrogen forms. As a fat-soluble root exudate, 1,9-decanediol has high stability in soil, is not easy to be leached away, and causes less environmental pollution. It further broadens an application field of 1,9-decanediol and improves an industrial value of 1,9-decanediol.
