Liming (soil)
Liming is the application (to soil) of calcium- (Ca) and magnesium (Mg)-rich materials in various forms, including marl, chalk, limestone, burnt lime or hydrated lime. In acid soils, these materials react as a base and neutralize soil acidity. This often improves plant growth and increases the activity of soil bacteria, but oversupply may result in harm to plant life. Liming can also improve aggregate stability on clay soils. For this purpose structure lime, products containing calcium oxide (CaO) or hydroxide (Ca(OH)2) in mixes with calcium carbonate (CaCO3), are often used. Structure liming can reduce losses of clay and nutrients from soil aggregates. The degree to which a given amount of lime per unit of soil volume will increase soil pH depends on the buffer capacity of the soil (this is generally related to soil cation exchange capacity or CEC). Soils with low CEC will usually show a more marked pH increase than soils with high CEC. But the low-CEC soils will witness more r ...

Liming (leather Processing)
Liming is a process used for parchment or leather processing, in which hides are soaked in an alkali solution. It is performed using a drum and paddle or a pit. Its objectives are: * Removal of interfibrillary proteins. * Removal of Keratin proteins. * Collagen swelling due to the alkaline pH. * Collagen fibre bundle splitting. * Removal of natural grease and fatsS.S. Dutta, ''An Introduction to the Principles of Leather Manufacture'', p. 160 Liming operations of cattle hides usually last 18 hours and are generally associated with the alkaline phase of beamhouse operations. Removal of interfibrillary proteins The interfibrillary proteins are denatured by the presence of alkali (particularly sodium sulfide), rendered soluble, facilitating their removal from the leather. Removal is done by the mechanical action of liming or reliming, but more prominently when the pelt is deswelled (during deliming). Failure to remove these proteins results in a hard, tinny leather (due to fib ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Birdlime
Birdlime or bird lime is an adhesive substance used in trapping birds. It is spread on a branch or twig, upon which a bird may land and be caught. Its use is illegal in many jurisdictions. Manufacture Historically, the substance has been prepared in various ways, and from various materials. In South Africa, birdlime (called ''voëlent'' in Afrikaans) is prepared from mistletoe fruits. A handful of ripe fruits is chewed until sticky, and the mass is then rubbed between the palms of the hands to form long and extremely sticky strands which are then coiled around small thin tree branches where birds perch. A popular form in Europe was made from holly bark, boiled for 10 to 12 hours. After the green coating is separated from the other, it is stored in a moist place for two weeks. It is then pounded into a thick paste, until no wood fibres remain, and washed in running water until no small specks appear. After fermenting for four or five days, during which it is frequently skimmed, ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
