TL;DR: In this paper, a special purpose after manuring complex mixed fertilizer for tobacco, which formed from ammonium nitrate, potassium sulfate, potassium nitrate and filling material, was described.
Abstract: The present invention relates to a special-purpose after manuring complex mixed fertilizer for tobacco, which formed from ammonium nitrate, potassium sulfate, potassium nitrate and filling material, and is characterized by that the ratio of total weight of said composite which and the content of nitrogen and potassium oxide is 6-17%:25-41%, which can meet that the nitrate nitrogen is 50-100% of total nitrogen quantity. Its production method includes: preparing raw materials, mixing materials, feeding materials, pulverizing, screening and after-treatment. Between material-feeding and pulverizing a compacting procedure for is added.

TL;DR: In this article, a method for preparing nanometer bismuth tungstate by utilizing a fused salt method is presented, where the raw materials are mixed and added into a molten salt system in a crucible.
Abstract: The invention discloses a method for preparing nanometer bismuth tungstate by utilizing a fused salt method. According to the method, bismuth nitrate and sodium tungstate are adopted as raw materials, potassium nitrate/sodium nitrate and lithium nitrate are utilized as a fuse salt system, the raw materials are mixed and added into a molten salt system in a crucible, and the nanoscale bismuth tungstate powder is obtained through reaction. According to the method, the uniform mixing of raw material on a molecule scale can be realized, and the nanoscale bismuth tungstate powder with high purity is obtained. The method provided by the invention has the advantages that the equipment is simple, the technological process is short, the operation is simple, the product performance is excellent, and the method has an extensive application prospect.

TL;DR: In this paper, solid state fermentation (SSF) technique was employed for the production of single cell protein (SCP) using white yam peels as a substrate, and the effect of supplementation by various inorganic sources of nitrogen on the crude protein yields was compared.
Abstract: Solid state fermentation (SSF) technique was employed for the production of single cell protein (SCP) using white yam peels as a substrate. Commercial baker’s yeast (S. cerevisiae) and a local isolate of A. niger were used for the fermentation process to generate crude protein. The effect of supplementation by various inorganic sources of nitrogen on the crude protein yields was compared. Ammonium sulphate [(NH4)2SO4], one of the inorganic nitrogen source used, supported the highest crude protein yields of 16.78% and 21.30% respectively for A. niger and S. cerevisiae while the lowest yield of 13.92% and 18.00% were supported by potassium nitrate and sodium nitrate respectively.
