Nutrient cycling in the mycorrhizosphere

Nutrient Relationships: Cycling

Nutrient Relationships: Cycling

Figure 1. Nutrients may be tied up in bryophytes for decades, or recycle within months, in forests with abundant bryophytes, as in this forest with Isothecium myosuroides. Photo by Michael Lüth. Few quantitative studies have addressed the role of bryophytes in ecosystem nutrient cycling. Nevertheless, bryophytes may play a significant role in N retention and release in the ecosystem (Figure 1)....

Forest Ecosystems: Nutrient Cycling

Nutrients are elements or compounds that are essential for the growth and survival of plants. Plants require large amounts of nutrients such as nitrogen (N), phosphorus (P), carbon (C), hydrogen (H), oxygen (O), potassium (K), calcium (Ca), and magnesium (Mg), but only small amounts of others such as boron (B), manganese (Mn), iron (Fe), copper (Cu), zinc (Zn) and chlorine (Cl) (micronutrients)...

Specificity of plant-microbe interactions in the tree mycorrhizosphere biome and consequences for soil C cycling

Mycorrhizal associations are ubiquitous and form a substantial component of the microbial biomass in forest ecosystems and fluxes of C to these belowground organisms account for a substantial portion of carbon assimilated by forest vegetation. Climate change has been predicted to alter belowground plant-allocated C which may cause compositional shifts in soil microbial communities, and it has b...

Nutrient cycling in a simulated pond ecosystem.

Mathematical modeling of ecosystems requires a considerable amount of knowledge about the subsystems functioning within the broad framework and the various rate processes and transfer coefficients that control the dynamic aspects. A detailed analysis of the transfer rates and budget of inorganic carbon and nutrients in a simulated pond was conducted for assessment and comparison with aquatic bo...
