Unit 3 Task 16
Carpenter, S. R., Caraco, N. F., Correll, D. L., Howarth, R. W., Sharpley, A. N., & Smith, V. H. (1998). Nonpoint pollution of surface waters with phosphorus and nitrogen. Ecological applications, 8(3), 559-568.
Mid-position adverbs:
Nutrient enrichment seriously degrades aquatic ecosystems… nutrient flows to aquatic ecosystems are directly related to animal stocking densities,… redepositing elsewhere and eventually reaching aquatic ecosystems…
They are partly incorporated into crops…
. Much of the N volatilized to the atmosphere is redeposited on land or water and eventually enters aquatic ecosystems
Intensive animal production generally involves feeding large numbers of animals in small areas
These percentages underestimate the total N flux to aquatic …show more content…
Oxygen shortages caused by senescence…
…manure production exceeds the needs of crops to which the manure is applied;
There is no use of time adverbials.
Active Voice:
Atmospheric deposition further contributes as a source of N.
In aquatic ecosystems, these nutrients cause diverse problems such as toxic algal blooms, loss of oxygen, fish kills, loss of biodiversity.
…eutrophication is a widespread problem in rivers, lakes, estuaries, and coastal oceans…
…excess fertilization and manure production cause a P surplus to accumulate in soil…
…excess fertilization and manure production on agricultural lands create surplus N…
Indirect questions
…manure production exceeds the needs of crops to which the manure is applied;
However, this pessimistic forecast could prove to be incorrect, because there are a number of ways that nonpoint pollution can be reduced.
Without concurrent reductions in nutrient sources to soils, however, soil nutrients will continue to accumulate.
Introducing solution:
There are direct solutions. Fertilizer application can be reduced to match crop
