The production of wet-process phosphoric acid generates a considerable quantity of acidic cooling water with high concentrations of phosphorus and fluoride. This excess water is collected in cooling ponds that are used to temporarily store excess precipitation for subsequent evaporation and to allow recirculation of the process water to the plant for reuse.

The biochars, prepared from coffee straw and eucalyptus bark at 350 and 600 C, were applied at five rates in a Red‐Yellow Oxisol. The application of biochars may reduce the demand for nutrients and correctives, optimise phosphorus fertilisation and improve the development of Brachiaria brizantha, but this ability depends on the raw material and the pyrolysis temperature used in its production.
This device may be used for the production of microbial metabolites such as antibiotics or enzymes; it may also be used for the growth of microorganisms i.e. production of microorganism itself. A low cost production unit has been developed for the production of microbial inoculants to be used as biofertilizers such as Rhizobium, Azotobacter, and Phosphate Solubilising Bacteria.

The production of yellow phosphorus, one of the major downstream products of phosphoric ore, is affected by the supply and demand of phosphoric ores. At present, the global yellow phosphorus production is highly concentrated, mainly in China, the US, Kazakhstan, the Netherlands and Vietnam. The production of yellow phosphorus is gradually ...
When symptoms of a nitrogen deficiency appear (pale green to yellow leaf color), apply 50 kg/ha of actual nitrogen at first-flower. PHOSPHORUS There are no specific symptoms for a phosphorus (phosphate) deficiency in soybeans.
It is noted that the removal of nontoxic and nonhazardous wastes materials derived from food-processing facilities (i.e. flour-rich waste streams, waste breads, etc), costs c. 0·4–0·7 US$ per kg of waste, and currently occurs mostly in the order these materials to
On this basis and phosphorus derivatives formed the chemistry of the synthesis process of glyphosate using iminodiacetonitrile and provides basic technological scheme of production of yellow phosphorus and glyphosate. The information submitted by perfecting
Phosphorus, essential to food production, is also a major pollutant in waterbodies due to inefficient use in agri-food systems, and vulnerable to supply and price shocks.
U.S. adopted VR application technologies for application of phosphorus and potassium fertilizers plus lime as long ago as the 1990''s. Variable rate application of phosphorus and potassium fertilizers plus lime has proven effective in reducing whole field input
deficit of phosphorus could become the main crop production limiting factor. Sewage sludge and other organic waste are a source of numerous biogens, in-cluding phosphorus (Singh and Agrawal 2008; Czechowska-Kosacka 2016;Wierzbowskaetal.
At present, pre-existing technological investment and cost issues make it unfeasible to employ alternative methods for the production of bulk phosphorus-containing chemical commodities. However, the use of alternate feedstocks for the synthesis of value-added specialty chemicals is very attractive both financially and from a health and safety perspective.
Chinese cereal production has increased steadily from 83.4 Mt in 1961 to 474.2 Mt in 2009 (), accounting for 9.5% of total global cereal production in 1961 and 21.8% in 2009. The net increase over this period is 390.8 Mt with an annual growth rate of 3.7%, which is substantially higher than the world mean growth rate in cereal production of 2% during the same period.
