Soil Defertilisation in order to reduce the number of plants that can grow on that soil. It is often done on land not intended for agriculture, such as city parks.
Soil defertilisation refers to the practice of reducing soil fertility Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality. Benefit On land not intended for agriculture, such as city parks or other communal spaces, undesired plants (weeds) can become a nuisance to the city's communal services, costing effort and money. In some cases, along with soil defertilisation, the soil's pH and water content can be altered. This may create a much different environment, allowing more specialised plants/vegetation to grow and take hold.In practice Soil defertilisation is done by growing[...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Soil Fertility
Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent Crop yield, yields of high quality.Bodenfruchtbarkeit Retrieved on 2015-11-09. It also refers to the soil's ability to supply plant/crop nutrients in the right quantities and qualities over a sustained period of time.A fertile soil has the following properties: * The ability to supply Plant nutrition, essential plant nutrients and water in adequate amounts and proportions for plant growth and reproduction; and * The absence of toxic substances which may inhibit plant growth e.g Fe^2+ which leads to nutrient toxicity. The following properties contribute to soil fertility in most situations: * Sufficient soil depth for adequate root g ...

Green Manure
In agriculture, a green manure is a crop specifically produced to be incorporated into the soil while still green. Typically, the green manure's biomass is incorporated with a plow or disk, as is often done with (brown) manure. The primary goal is to add organic matter to the soil for its benefits. Green manuring is often used with legume crops to add nitrogen to the soil for following crops, especially in organic farming, but is also used in conventional farming. Functions Green manures usually perform multiple functions that include soil improvement and soil protection: * Leguminous green manures such as clover and vetch contain nitrogen-fixing symbiotic bacteria in root nodules that fix atmospheric nitrogen in a form that plants can use. This performs the vital function of fertilization. :Depending on the species of cover crop grown, the amount of nitrogen released into the soil lies between 40 and 200 pounds per acre. With green manure use, the amount of nitrogen tha ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Phacelia
''Phacelia'' (phacelia, scorpionweed, heliotrope) is a genus of about 200 species of annual or perennial herbaceous plants in the borage family, native to North and South America. California is particularly rich in species with over 90 recorded in the region. The genus is traditionally placed at family rank with the waterleafs ( Hydrophyllaceae) in the order Order, ORDER or Orders may refer to: * Categorization, the process in which ideas and objects are recognized, differentiated, and understood * Heterarchy, a system of organization wherein the elements have the potential to be ranked a number of d ... Boraginales. The Angiosperm Phylogeny Group, recognizing that the traditional Boraginaceae and Hydrophyllaceae are paraphyletic with respect to each other, merges the latter into the former and considers the family Basal (phylogenetics), basal in the Euasterids I clade. Other botanists continue to recognize the Hydrophyllaceae and Boraginales after analysing the secondary ...

White Mustard
White mustard (''Sinapis alba'') is an annual plant of the family Brassicaceae. It is sometimes also referred to as ''Brassica alba'' or ''B. hirta''. Grown for its seeds, used to make the condiment mustard, as fodder crop, or as a green manure, it is now widespread worldwide, although it probably originated in the Mediterranean region. Description White mustard is an annual, growing to high with stalkless pinnate leaves, similar to ''Sinapis arvensis''. Distribution Most common in Europe, North Africa, the Middle East and Central Asia, it can be found worldwide. It has been found as far north as Greenland, and naturalized throughout Great Britain and Ireland. Culinary uses The yellow flowers of the plant produce glabrous or sparsely bristled seed pods. Each fruit (silique) contains roughly a half dozen seeds. The plants are harvested for their seeds just prior to the seed pods becoming ripe and bursting open (dehiscing). White mustard seeds are hard spheroid seeds, usual ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Lolium Multiflorum
''Lolium multiflorum'' (Italian rye-grass, annual ryegrass) is a ryegrass native to temperate Europe, though its precise native range is unknown. It is a herbaceous annual, biennial, or perennial grass that is grown for silage, and as a cover crop. It is also grown as an ornamental grass. It readily naturalizes in temperate climates, and can become a noxious weed in arable areas and an invasive species in native habitats. It is a host plant to wheat yellow leaf virus in its native Europe. It is sometimes considered a subspecies of perennial ryegrass (''Lolium perenne''). It differs from ''L. perenne'' in its spikelet, which has a long bristle at the top, and its stem, which is round rather than folded. It can be mistaken for couch A couch, also known as a sofa, settee, or chesterfield, is a cushioned item of furniture for seating multiple people (although it is not uncommon for a single person to use a couch alone). It is commonly found in the form of a bench with u ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Fertilizer
A fertilizer (American English) or fertiliser (British English; see spelling differences) is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients. Fertilizers may be distinct from liming materials or other non-nutrient soil amendments. Many sources of fertilizer exist, both natural and industrially produced. For most modern agricultural practices, fertilization focuses on three main macro nutrients: nitrogen (N), phosphorus (P), and potassium (K) with occasional addition of supplements like rock flour for micronutrients. Farmers apply these fertilizers in a variety of ways: through dry or pelletized or liquid application processes, using large agricultural equipment or hand-tool methods. Historically fertilization came from natural or organic sources: compost, animal manure, human manure, harvested minerals, crop rotations and byproducts of human-nature industries (i.e. fish processing waste, or bloodmeal ...
