摘要:
The present development is a composition for a commercial fertilizer product that provides for nitrogen, phosphate and/or potassium availability to the plant even in a hostile growing environment with hard water sources. The fertilizer of the present invention includes a polyamine additive, water, and soluble nitrogen, potassium, and/or phosphate, that are essentially unaffected by hard water thereby retaining their availability to the target plants.
摘要:
A fertilizer granule having a coating on at least of portion of a surface of the granule. The coating is made of one or more complexing agents and a coating agent of one or more of a fatty acid, fatty acid ester, organic oil mineral oil or combinations thereof. The coating may optionally include a surfactant and micronutrients. The coated fertilizer granules demonstrates a noted improvement in the utilization of the nutrients of plants and crops.

摘要:
A process for producing desired compounds from biomass, including treating a lignocellulosic waste stream in some embodiments. The waste stream is conditioned under acidic or basic conditions, and is then treated in a catalytic reaction step using a transition metal catalyst and an oxidant. The transition metal catalyst can be an iron-based nanoparticulate catalyst. In some embodiments, useful compounds such as lignin, crystalline cellulose and various platform chemicals are produced from the waste stream. In some embodiments, the waste stream is lignocellulosic agricultural or forestry waste. In some embodiments, the waste stream is manure. In some embodiments, desirable bioproducts are obtained from lignocellulosic biomasses using an iron-based nanoparticulate-catalyzed reaction conducted at alkaline pH.
摘要:
An alkali metal ion source with a moderate rate of release of the ion (e.g. potassium) is formed by a method that includes: 1) combining an particulate ore that contains at least one of an alkali metal ion-bearing framework silicate (e.g. syenite ore) with at least one of an oxide and hydroxide of at least one of an alkali metal and alkaline earth metal such as calcium hydroxide; 2) milling the mixture of these two components optionally, with water, optionally, milling the dry components separately and blended thereafter, optionally, with water; 3) forming a mixture by adding water to the solid mixture after milling, if water was not added before milling; 4) exposing the mixture to an elevated temperature and pressure to form a gel that includes silica and the alkali metal of the framework silicate.

An agricultural potassium-fertigation method for emitter-irrigation potassium fertigation feeds a potassium-nutrient feedstock comprised of potassium formate and water to an active emitter-irrigation system during one to all irrigation days during a crop cycle.
摘要:
The invention relates to an integrated process for the production of 5-hydroxymethyl furfural (HMF), K2SO4, levulinic acid and formic acid from κ-carrageenan, the latter being obtained from fresh Kappaphycus alvarezii seaweed biomass after expelling the juice. Mg(HSO4)2 was used in HMF synthesis, with co-production of galactose. The aqueous stream after HMF extraction was treated with the seaweed juice which process facilitated recovery of K2SO4 in pure form. The galactose may be utilised for synthesis of levulinic acid and formic acid before or after K2SO4 recovery or, alternatively, utilised for other purposes. Catalysts required in the synthetic reactions are generated in the process itself while the process energy required is met out of additional supplies of the seaweed biomass which is subjected to combustion/gasification.

摘要:
The invention provides for methods, devices, and systems for pyrolyzing biomass. A pyrolysis unit can be used for the pyrolysis of biomass to form gas, liquid, and solid products. The biomass materials can be selected such that an enhanced biochar is formed after pyrolysis. The biomass can be pyrolyzed under specified conditions such that a selected biochar core is formed. The pyrolysis process can form a stable biochar core that is inert and/or resistant to degradation. The biochar or biochar core can be functionalized to form a functionalized biochar or functionalized biochar core. Functionalization can include post-pyrolysis treatments such as supplementation with microbes or physical transformations including annealing and/or activation.
