Atmospheric electricity utilization for the chemical reaction in which water is separated into oxygen and hydrogen. (Image via: Vion, US patent 28793. June 1860.) Electrolyser front with electrical panel in foreground. Electrolysis of water is the decomposition of water (H 2 O) into oxygen (O 2) and hydrogen (H 2): [2] Water electrolysis ship ...
This mineral nitrogen is said to be immobilized. This may reduce the concentration of inorganic nitrogen in the soil and thus the nitrogen is not available to plants. As carbon dioxide is released during the generation of energy in decomposition, a process called "catabolism", the C:N ratio of the organic matter decreases. When the C:N ratio is ...
Decomposition rates are low under very wet or very dry conditions. Decomposition rates are highest in damp, moist conditions with adequate levels of oxygen. Wet soils tend to become deficient in oxygen (this is especially true in wetlands), which slows microbial growth. In dry soils, decomposition slows as well, but bacteria continue to grow ...
Bioenzymes are also bio catalyst. They are prepared by fermentation of organic waste, jaggery and water in ratio 3:1:10 for three months. It increases the soil microbe population and speeds up composting and decomposition and so is included in catalyts. It heals the soil. It is one of the best best organic liquid fertilizer. It is diluted with ...
The dry matter consists mainly of carbon, oxygen, and hydrogen. Although these three elements make up about 92% of the dry weight of the organic matter in the soil, other elements present are essential for the nutrition of plants, including nitrogen, phosphorus, potassium, sulfur, calcium, magnesium, and many micronutrients.

Soil chemistry is the study of the chemical characteristics of soil.Soil chemistry is affected by mineral composition, organic matter and environmental factors. In the early 1870s a consulting chemist to the Royal Agricultural Society in England, named J. Thomas Way, performed many experiments on how soils exchange ions, and is considered the father of soil chemistry. [1]
Compost tea is made up of extracts of fermented water leached from composted materials. [ 67 ] [ 73 ] Composts can be either aerated or non-aerated depending on its fermentation process. [ 74 ] Compost teas are generally produced from adding compost to water in a ratio of 1:4–1:10, occasionally stirring to release microbes .
Some plants are sensitive indicators of the chemical environment in which they grow (Dunn 1991), [19] and some plants have barrier mechanisms that exclude or limit the uptake of a particular element or ion species, e.g., alder twigs commonly accumulate molybdenum but not arsenic, whereas the reverse is true of spruce bark (Dunn 1991).
