Furthermore, because epiphytes intercept and retain carbon and nitrogen, they can significantly affect nutrient cycles
(Benzing and Seemann, 1978).
Enzymatic activity is also commonly used to estimate activities related to specific nutrient cycles
(GIACOMETTI et al.
dairy farms 'Cows & Opportunities' in the original situation.
They also export nutrients, but these are recovered by other organisms, forming a relatively closed nutrient cycle
The decline in natural soil fertility due to the disruption of the soil nutrient cycle
accompanying capitalist agriculture, the growing knowledge of the need for specific soil nutrients, and limitations in the supply of both natural and synthetic fertilizers that would compensate for the loss of natural fertility, all contributed, therefore, to a widespread sense of a crisis in soil fertility.
Attention was given to that major part of the nutrient cycle
which included litterfall, decomposition, mineralization, and replenishment of the soil phosphorus pools.
Alliance Environmental is a recognized expert in the area of distributed green infrastructure and provides services to municipalities and private developments that seek to reduce the costs and environmental impacts of new and existing systems by optimizing water, carbon and nutrient cycle
That is a really powerful teaching tool," says Saxenian; "It turns the out-of-sight out-of-mind mentality around," and stimulates discussion of the nutrient cycle
Finally, it should be pointed out that, while in a "natural" ecosystem the nutrients are partly recycled within the same ecosystem, which we refer to as a nutrient cycle
, in a city the nutrients are not recycled, and we would have to describe this as a nutrient flow, rather than cycle.
Nutrient dynamics in mires of various trophic status: nutrient inputs and outputs and the internal nutrient cycle
The constant deposition and leaching that Van der Valk measured in coastal foredune communities are characteristic of a very inefficient nutrient cycle
Throughfall and stemflow in the forest nutrient cycle
