Rareearth humic acid complete compound fertilizer, its preparation method and use

Abstract: The composition of the rare earth humic acid complete composite fertilizer contains rare earth, urea, diammonium phosphate and/or monoammonium phosphate, potassium nitrate and/or potassium chloride and/or potassium fulfate, silicon dioxide, calcium dioxide, magnesium oxide, zinc sulfate, manganese sulfate, ferrous sulfate, copper sulfate, borax, ammonium molybdate and humic acid. Its preparation method includes the following steps: mixing the described nitrogen fertilizer, phosphate fertilizer and potassium fertilizer, spraying water to make them into paste material, adding rare earth and other materials, stirring them uniformly, granulating and drying so as to obtain the invented product.

Non-toxic fresh-preservative and preparation method thereof

Abstract: The non-toxic fresh-preservative for fresh flowers is prepared from alum, sodium benzoate, glucose, ascorbic acid, aspirin, zinc sulfate, ammonium, magnesium sulfate, potassium permanganate, sodium chloride, ferrous sulfate, potassium nitrate, urea and filler by pulverizing, fractional uniformly mixing, checking and packing. The finished product is water-soluble powder of 98% with blue-white colour, and is non-toxic. It has the advantage of simple technology, low cost, convenient preservation and transportation, wide-sepctrum etc..

Special selenium-rich liquid fertilizer for moso bamboo shoots and preparation method of fertilizer

Abstract: The invention relates to a special selenium-rich liquid fertilizer for moso bamboo shoots and a preparation method of the fertilizer. The liquid fertilizer comprises an organic and inorganic mixed selenium source prepared from potassium nitrate, potassium dihydrogen phosphate, dipotassium hydrogen phosphate, boric acid, EDTAZnNa2, EDTAMnNa2, NaFeEDTA, sodium silicate, ammonium molybdate, 5-nitroguaiacol sodium salt, sodium dodecyl benzene sulfonate, sodium benzoate and a selenium-rich yeast, wherein the organic and inorganic mixed selenium source is formed by preparing the selenium-rich yeast into a seed and then carrying out fermentation enrichment culture, inactivation and decomposition in an inorganic selenium containing culture medium. The preparation method comprises the following steps of dissolving effective components according to a certain sequence; regulating a pH value; and treating until constant volume is achieved. The special selenium-rich liquid fertilizer for the moso bamboo shoots, which is disclosed by the invention, has the advantages of comprehensive nutrient element, reasonable and safe formula, high fertilizer utilization ratio, no environmental pollution and the like, is convenient to fertilize, improves the utilization efficiency of a selenium element and increases the selenium content of bamboo shoots by using an organic selenium source and ensures the safety in fertilizer use and selenium-rich moso bamboo shoot eating.

Special liquid soil conditioner for improving saline land, increasing yield, controlling pests and reducing residues and preparation method of special liquid soil conditioner

Abstract: The invention discloses a special liquid soil conditioner for improving saline land, increasing yield, controlling pests and reducing residues. The special liquid soil conditioner is prepared from the following raw materials in percentage by weight: 6.5-16.5% of microbial flora, 2-6% of humic acid, 3-5% of urea, 2-4% of ammonium nitrate, 1-3% of ammonium sulfate, 2-3% of phosphoric acid, 1-2% of monoammonium phosphate, 1-2% of diammonium phosphate, 2-3% of calcium superphosphate, 1-2% of potassium sulfate, 1-3% of potassium nitrate, 2-3% of magnesium-potassium sulfate, 1-2% of amino acid, 1-2% of boric acid, 0.4-1.0% of insecticide, 9.1-17% of separant, 0.5-1.5% of plant growth regulator and the balance of water. All the raw materials are uniformly mixed and dissolved to obtain the special liquid soil conditioner. By using the conditioner, the nitrogen content of soil is increased by 20-100%, the yield increasing rate is up to 30-60% on the year-on-year basis, the fatality rate of pests is up to 90-100%, and the residue reducing rate is up to 20-40 on the year-on-year basis.

Methods of producing, marketing and using odor control compositions

Abstract: Odor control compositions include a source of nitrogen, a non-salt source of oxygen, and a surfactant. The compositions added to a biomass in a concentration sufficient to produce a noticeable stimulation of aerobic activity. Preferred compositions include at least one of ammonium nitrate and urea, as well as calcium nitrate, and more preferred compositions also include potassium nitrate. Related methods include use of the compositions in treating a wide range of odors emanating from sewage and other flowable materials, air, and solid surfaces.
