This is done through appropriate soil preparation and the introduction of suitable plant species. It is also necessary to make adequate water harvesting systems—ideally taking advantage of the degradation process of the slope, collecting runoff water in ponds around the sites to be forested.
The opposite effect is known as eutrophication or nutrient pollution. [6] Both depletion and eutrophication lead to shifts in biodiversity and species abundance (usually a decline). [7] The effects are bidirectional in that a shift in species composition in a habitat may also lead to shift in the nutrient composition. [8]
Thus, eutrophication has been defined as "degradation of water quality owing to enrichment by nutrients which results in excessive plant (principally algae) growth and decay." [8] Eutrophication was recognized as a water pollution problem in European and North American lakes and reservoirs in the mid-20th century. [9]
2. Arranged on opposite sides, e.g. leaves on a stem; Compare distichous and opposite. 3. Bilaterally symmetrical, as in a leaf with a symmetrical outline. biloculate Having two loculi, e.g. in anther s or ovaries. binomial Making use of names consisting of two words to form the scientific name (or combination) in a Latin form.
Also, plants with deep reaching roots can transpire water more constantly, because those roots can pull more water into the plant and leaves. Another example is that conifer forests tend to have higher rates of evapotranspiration than deciduous broadleaf forests, particularly in the dormant winter and early spring seasons, because they are ...
plankton – mostly microscopic animal and plant life suspended in water and a valuable food source for animals cf. Phytoplankton. plant quality - a standard of plant appearance or yield. plastic - One of many high-polymeric substances, including both natural and synthetic products, but excluding rubbers. At some stage in its manufacture every ...
Water resources, such as lakes and aquifers, are usually renewable resources which naturally recharge (the term fossil water is sometimes used to describe aquifers which do not recharge). Overexploitation occurs if a water resource, such as the Ogallala Aquifer , is mined or extracted at a rate that exceeds the recharge rate, that is, at a rate ...
Hydrotropism (hydro- "water"; tropism "involuntary orientation by an organism, that involves turning or curving as a positive or negative response to a stimulus") [1] is a plant's growth response in which the direction of growth is determined by a stimulus or gradient in water concentration. A common example is a plant root growing in humid air ...
