Provided is an organic-inorganic polymeric water-retaining fertilizer, which is a co-polymer made by fusion and co-polymerization of an organic water-retaining monomer and an inorganic nutrient under action of a catalyst, a biological enzyme and a modifying agent. The co-polymer is of a three-dimensional mesh-like hydrophilic group structure. In a method for preparing the organic-inorganic polymeric water-retaining fertilizer, after obtaining a neutralized pre-polymer from the organic monomer with the catalyst, an initiator and a cross-linking agent are added; the inorganic nutrient and a metasilicate are added simultaneously, a solution is formed by stirring sufficiently; the biological enzyme is added for catalysis; a co-polymer is obtained after fusion and co-polymerization; and granulation and drying are carried out. Preferably, the catalyst is an inorganic alkaline solution. Preferably, the catalyst is selected from the group consisting of a sodium hydroxide solution, a potassium hydroxide solution, an ammonia water and a calcium hydroxide solution.

The present invention provides organic slow-acting fertilizer using psyllium seed husk and a method for producing the same. Macroelements or secondary elements selected from 12 essential nutrient elements (N, P, K, Ca, Mg, S, Fe, Mn, Cu, B, Mo, and Zn) for edible plants are extracted from each of oil cake (collectively referring to residue remaining after extraction of vegetable oil, and including soybean oil cake, palm oil cake, etc.), blood meal (livestock blood), dead fish or bonefish-containing by-products, bone meal, Dead Sea mineral, egg shell, seashell, oystershell, natural gypsum, dolomite, phyllite, and natural salt, by a predetermined extraction process, and are impregnated in larger amounts into a porous material such as zeolite, and organic fertilizers are produced in the form of psyllium seed husk-bound grains for more rapid and effective impregnation so that suitable proportions of element fertilizers can be supplied to each type of plant.

The present invention provides a new fertilizer comprising water and an organic potassium source wherein the fertilizer composition has a pH range of from 5.5 to 10.0 and a salt index no greater than about 40 as measured by electrical conductivity methods. The organic potassium source is selected from the group consisting of potassium acetate, potassium formate, potassium citrate, potassium succinate, potassium propionate, and combinations thereof. The fertilizer demonstrates lower phytotoxicity damage compared to other sources of potassium for fertilizer products. The fertilizer composition may further comprise nitrogen, phosphorus, sulfur, zinc, boron, calcium, manganese, iron, copper, cobalt, magnesium, molybdenum, inoculants, or a combination thereof.

An organic fertilizer/plant food containing molasses to increase microorganism activity in soils. The molasses provides additional nutrients to the soil that are readily available for plant intake. The molasses provides sugars to increase microorganism activity to benefit soil structure before the slower process of microorganism break-down of other organic materials can occur. The molasses may be applied to the fertilizer mixture in various ways including by spraying.

The present invention relates to a method of preparing a wood chip-type organic composite fertilizer wherein the method comprises the steps of: {circle around (a)} preparing wood chips by chipping; {circle around (b)} preparing a liquid organic fertilizer; {circle around (c)} forming an organic mixed solution; {circle around (d)} obtaining colored wood chips by simultaneously immersing the wood chips of the step {circle around (a)} in the organic mixed solution of the step {circle around (c)} and applying hot air to the organic mixed solution to coat the woods chips with colors; {circle around (e)} drying the wood chips to a high temperature to remove moisture formed on an outer surface of the wood chips of the step {circle around (d)} and to make the organic mixed solution penetrate evenly into the wood chips at the same time; and {circle around (f)} packing the dried wood chips of the step {circle around (e)} by weight unit with the measurement thereof on a scale.
