Calcium nitrate with 15,5% nitrogen and 19% calcium, reportedly holding a small share of the nitrogen fertilizer market (4% in 2007). [28] The main straight phosphate fertilizers are the superphosphates: "Single superphosphate" (SSP) consisting of 14–18% P 2 O 5, again in the form of Ca(H 2 PO 4) 2, but also phosphogypsum (CaSO 4 · 2 H 2 O).
The RFC specifies this code should be returned by teapots requested to brew coffee. [18] This HTTP status is used as an Easter egg in some websites, such as Google.com's "I'm a teapot" easter egg. [19] [20] [21] Sometimes, this status code is also used as a response to a blocked request, instead of the more appropriate 403 Forbidden. [22] [23]
The values in an NPK fertilizer label are related to the concentrations (by weight) of phosphorus and potassium elements as follows: 5 consists of 56.4% elemental oxygen and 43.6% elemental phosphorus by weight. Therefore, the elemental phosphorus percentage of a fertilizer is 0.436 times its P value.

A controlled-release fertiliser ( CRF) is a granulated fertiliser that releases nutrients gradually into the soil (i.e., with a controlled release period). [ 2] Controlled-release fertilizer is also known as controlled-availability fertilizer, delayed-release fertilizer, metered-release fertilizer, or slow-acting fertilizer.

Phosphatidylinositol 4,5-bisphosphate or PtdIns (4,5)P2, also known simply as PIP2 or PI (4,5)P2, is a minor phospholipid component of cell membranes. PtdIns (4,5) P2 is enriched at the plasma membrane where it is a substrate for a number of important signaling proteins. [ 1] PIP2 also forms lipid clusters [ 2] that sort proteins. [ 3][ 4][ 5]
2,4,5-Trichlorophenoxyacetic acid (also known as 2,4,5-T ), a synthetic auxin, is a chlorophenoxy acetic acid herbicide used to defoliate broad-leafed plants. It was developed in the late 1940s, synthesized by reaction of 2,4,5-Trichlorophenol and chloroacetic acid. It was widely used in the agricultural industry until being phased out ...
