The Living World: Ecosystems

Urban heat island effect accelerates biological decomposition releasing excess phosphorus.

Enhanced evapotranspiration from landscaped greenspaces reduces available phosphorus.

Direct deposition coal emissions rich in phosphorus in residential areas.

Increased stormwater runoff carrying waste that contributes nutrients to bodies.

It decreases atmospheric deposition rates on land surfaces.

It increases surface runoff carrying phosphates into waterways.

It reduces animal grazing which otherwise depletes soil phosphate levels.

It heightens biological nitrogen fixation thus reducing phosphate usage.

Use gypsum binds with excess soluble phosphate reducing its leaching into waterways.

It facilitates the conversion of insoluble phosphates to soluble forms making them more biologically available.

Application aims at increasing atmospheric phosphorus deposition onto cropland through enhanced mineral dust uptake.

Gypsum supplements naturally low phosphorus contents which bolsters plant growth.

It could minimize groundwater contamination with phosphates resulting from septic system leakage and lawn fertilizer runoff.

Limiting urban sprawl has no indirect effects on the cycle since it primarily involves atmospheric transport processes.

These changes are likely to decrease terrestrial carbon storage capacity, disrupting both carbon and adjacent cycles like that of phosphorous.

Such zoning laws typically increase erosion rates, causing greater displacement and distribution of available soil-borne phosphates.

Deforestation enhances atmospheric precipitation rates, leading to enhanced mobilization and deposition of phosphorus over wider geographical ranges.

Forest clearing promotes accelerated mineral weathering processes, hence increasing bioavailable phosphorus reservoirs significantly.

Forest loss encourages greater carbon sequestration in rocks, releasing additional amounts of essential elements for ecosystem functions.

Deforestation reduces root system stabilization, accelerating erosion and thus limiting the availability of biotically recyclable forms of phosphorus.
