Carnivorous types, however, colonize marginal habitats with impoverished soil and must acquire their nutrients from alternative sources.
Over time, the team maintains, sunflowers and mustard seed can restore the High Line's impoverished soil to full life-bearing capability.
Growth in the more impoverished soil medium was slower than observed for J2315 grown in CF medium, but at least a single doubling was observed which was sufficient for gene expression under the soil conditions.
Most Americans eat foods manufactured from large-scale commodities grown chemically on impoverished soils, or from animals crowded into sheds and raised on unnatural feeds.
The Kano concentration is based on intensive agriculture in an area of relatively fertile soils, but the densely settled areas around nearby Katsina have impoverished soils and do not produce enough food for the local population.
Various forms of leucaena (such as Leucaena leucocephala) have been developed for animal forage, firewood, and construction, as well as for the high production of nitrogen that enriches impoverished soils, especially in the Asiatic tropics.
The far west and north are remote zones of low potential, because of aridity in the southwest and because of highly seasonal rainfall and impoverished soils and grasslands in the north.
The occurrence of widespread and endemic species in this megadiverse mountain environment might be attributed to distinct physiological strategies of species to cope with high light levels and impoverished soils.
In this study, we sought to compare photosynthetic and leaf nutrient-use strategies in widespread and endemic species that allow its adjustments to high light and impoverished soils in campo rupestre.
However, one must be conscious that: (1) new plantings in the impoverished soils and increasing aridity of southern Australia will take many decades to mature, and, also, will offer suitable habitats for a sequence of different species over the course of that maturation process; and (2) much existing vegetation is senescent or will be in a few decades' time.
Physiology, agronomy and ecology can simultaneously contribute to the improvement of intercropping systems, allowing to enhance crop productivity and resource-use efficiency, so making intercropping a viable approach for sustainable intensification, particularly in regions with impoverished soils and economies where measured benefits have been greatest [93].
