The present invention relates to organic nitrogen fertilizers and methods for producing organic nitrogen fertilizers, including retrieving high concentration organic ammonia from discarded organic material.

An improved composition and method for stimulating plant growth and productivity, the composition of which can be adjusted to provide a preferred pH level that is ideal for growing plants in order to enhance the uptake of certain nutrients in growing such plants. The composition comprises combinations of Citric Acid, Disodium Hydrogen Phosphate or one of its hydtares, Boric Acid and Trisodium Phosphate or Trisodium Phosphate Dodecahydrate dissolved with a set quantity of water.

Liquid fertilizer compositions and methods of making and using the compositions for fertilizing crops are provided. A liquid fertilizer formulated to enhance plant growth is infused with nano-bubbles that increase the efficacy of the liquid fertilizer. The liquid fertilizer is mixed and homogenized before flowing the liquid fertilizer through a nano-bubble generator. The liquid fertilizing composition infused with nano-bubbles may be applied to soil in the same manner as standard liquid fertilizers to further promote plant growth.

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.

A method and system is provided for treating water to remove contaminants using treated biochar placed in the water flow pathway of a water treatment process. The system further includes the further treatment of the treated biochar after its use in the water treatment process for use in agricultural or animal applications.

A prepared method of arginine chelated selenium foliar fertilizer which is benefit for improving herbage seed yield is provided. The prepared foliar fertilizer is conducive to significantly promote the yields of herbage and seeds. The weight and diameter of the seeds and the contents of fat, polysaccharide, isoflavone and selenium contained in the herbage seeds have increased obviously. Seed is the chip of agriculture. High yield and quality of herbage seeds provide a good basis for forage production, which not only develops livestock industry, but also plays an important role in protecting ecological environment.
