Phosphite Fertilizers: What Are They? Can You Use Them

cal oxidation process can be too slow (de-pending on soil conditions, temperature, and presence of phosphite-metabolizing microbes) to be of agricultural significance for some annual crops. However, when crops are replanted in the previously phos-phite-fertilized soil, their performance is similar to crops grown in phosphate-fertil-ized soil. These toxic effects and the addi-tional expense

Phosphite What’s all the fuzz about? Pitchcare

06/05/2013 Phosphite is derived from phosphorous acid (H 2 PO 4), which has a pH of 2.2 and, if applied directly to plant tissues, would cause burn. So, to prevent phytotoxicity, it has to be modified prior to use with a neutralising substance, the most commonly used being potassium hydroxide (KOH).

Jigs and Fixtures: Definition, Types, Differences

Both the jigs and the fixtures are used to reduce the nonproductive time of any mass production process. The principle of location or the 3-2-1 principle, CAD tools (like ProE), and FEA tools (like ANSYS) are used for the design of the jigs as well as the fixtures. The jig is used for guiding the cutting tool (like a drill bit), and for doing so, jigs have components like a bush, which comes
