摘要:
The present invention relates to a completely biodegradable organic product designed for producing a road snow melting/ground thawing agent or a biological agricultural fertilizer, comprising at least one salt, for example in the form of grit, brine or slurry, characterized in that it further comprises a material of plant origin consisting of at least one waste product from an oil pressing/extracting, winemaking or crushing process.
摘要:
A granular cohered MOP fertilizer having one or more micronutrients, and one or more binding ingredients. The fertilizer is prepared by compacting MOP feed material with one or more micronutrients and one or more optional binders to form a cohered MOP composition. The cohered MOP composition is then further processed, such as by crushing and sizing, to form a cohered granular MOP product containing micronutrients. The process yields a fertilizer product containing micronutrients with superior elemental and granule size distribution without comprising handling or storage qualities.

A method is disclosed for producing sulphate or phosphate-based fertilizer from hydrogen sulphide. The method involves feeding a stream containing a substantial volume of hydrogen sulphide and air to a furnace, where it is burned to produce a sulphur dioxide rich gas stream. The sulphur dioxide rich gas stream is then fed to a reactor to produce a sulphuric acid stream and a waste stream comprising carbon dioxide, nitrogen, oxygen, trace impurities and trace amounts of unreacted sulphur dioxide. The sulphuric acid stream is finally converted to a sulphate or phosphate-based fertilizer.
摘要:
An electrochemically treated solution and method for cut flower and plant preservation, the solution having potassium, hypochlorous acid, and dissolved oxygen.
摘要:
The invention relates to a potassium sulphate powder wherein about 80 wt % or more of the powder has a particle size of about 0.2 mm or lower, preferably about 0.13 mm or less. The particle size preferably is such, that about 80 wt % or more is about 0.02 mm or higher, more preferably about 0.04 mm or higher. This potassium sulphate powder dissolves easily in water, more in particular, 50 gram of said potassium sulphate powder dissolves in 1 liter of water without stirring within 1 minute, preferably within 30 sec. This potassium sulphate powder is very suitable as foliar fertilizer, in particular for broad acre crops. Further, the invention relates to the use of foliar potassium fertilizer, to enhance the uptake of potassium from the soil.
摘要:
A method forming a potassium chloride particle form potassium chloride powder having resistance to moisture absorption and shrinkage. The original feedstock comprises potassium chloride in a size distribution of 30 mesh and 100 mesh as well as a gluten based binder.
摘要:
A stabilized lime slurry for treatment of biological solids in sewage. The composition preferably includes 30-36% calcium hydroxide, 10-16% potassium hydroxide, 2-4% potassium chloride, 2-4% magnesium hydroxide, all on a dry basis, and the balance in water. This composition raises the pH rapidly for destroying pathogens, is sufficiently concentrated for economically feasible transportation, and reduces the cost, difficulties and dangers of treating sewage with a lime based composition while providing a resulting product from the sewage treatment process which can be spread upon agricultural soil in a manner which improves soil fertility without introducing undesirable or contaminating materials into the soil.
摘要:
A process for producing K.sub.2 SO.sub.4 from potassium chloride salts, calcium sulfate salts and another sulfate source wherein syngenite is formed and then decomposed with mineral acid to produce crystalline K.sub.3 H(SO.sub.4).sub.2. The K.sub.3 H(SO.sub.4).sub.2 crystals are recrystallized to produce K.sub.2 SO.sub.4 crystals.
