Like other iron(II) salts, iron(II) sulfate is a reducing agent. For example, it reduces nitric acid to nitrogen monoxide and chlorine to chloride: 6 FeSO 4 + 3 H 2 SO 4 + 2 HNO 3 → 3 Fe 2 (SO 4) 3 + 4 H 2 O + 2 NO 6 FeSO 4 + 3 Cl 2 → 2 Fe 2 (SO 4) 3 + 2 FeCl 3. Its mild reducing power is of value in organic synthesis. [44]
Stachys byzantina (syn. S. lanata), the lamb's-ear [2] (lamb's ear) [3] or woolly hedgenettle, [4] is a species of flowering plant in the mint family Lamiaceae, native to Armenia, Iran, and Turkey. [ 5 ] [ 6 ] It is cultivated throughout much of the temperate world as an ornamental plant , and is naturalised in some locations as an escapee from ...
Hazard analysis and critical control points, or HACCP (/ ˈ h æ s ʌ p / [1]), is a systematic preventive approach to food safety from biological, chemical, and physical hazards in production processes that can cause the finished product to be unsafe and designs measures to reduce these risks to a safe level. In this manner, HACCP attempts to ...
annual: a plant species that completes its life cycle within a single year or growing season; basal: attached close to the base (of a plant or an evolutionary tree diagram) climber: a vine that leans on, twines around or clings to other plants for vertical support; deciduous: falling seasonally, as with bark, leaves or petals
Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...
Chenopodium album is a fast-growing annual plant in the flowering plant family Amaranthaceae. Though cultivated in some regions, the plant is elsewhere considered a weed . Common names include lamb's quarters , melde , goosefoot , wild spinach and fat-hen , though the latter two are also applied to other species of the genus Chenopodium , for ...
The half-life for pesticides is explained in two NPIC fact sheets. Known degradation pathways are through: photolysis, chemical dissociation, sorption, bioaccumulation and plant or animal metabolism. [46] [47] A USDA fact sheet published in 1994 lists the soil adsorption coefficient and soil half-life for then-commonly used pesticides. [48] [49]
The agriculture industry is one of the most dangerous occupations and has led to thousands of deaths due to work-related injuries in the US. In 2011 the fatality rate for farmworkers was 7 times higher than that of all the workers in the private industry, a difference of 24.9 deaths for every 100,000 people as opposed to 3.5 deaths for every 100,000 people in the private industry.
