TLDR
Clear Lake, a small Canadian Shield lake that has been influenced little by human activity, was found to be more productive than expected from chemical and optical properties and geological surroundings, although most of the sodium, potassium, and silica entering the lake is weathered from the terrestrial watershed.Abstract:

The phosphorus‐chlorophyll relationship in lakes1,2
P. J. Dillon,F. H. Rigler +1 more
TL;DR: In this article, data for summer chlorophyll and spring total phosphorus concentration were collected from 19 lakes in southern Ontario and combined with data reported in the literature for other North American lakes to produce a regression line that can be used to predict the average summer CHP from a single measurement of phosphorus concentration at spring overturn.

Input-output models
TL;DR: In this paper, mass balance and export models are explored in relation to eutrophication as caused by phosphorus and nitrogen in lakes and it is shown that lakes having long water renewal times are much more sensitive to phosphorus loading than would appear from mean depth only.

The effects of geology and land use on the export of phosphorus from watersheds
P.J. Dillon,W.B. Kirchner +1 more
TL;DR: In this paper, the export of total phosphorus from 34 watersheds in Southern Ontario was measured over a 20-month period, and the average export was 48 mg m−2 yr−1, significantly different from the average (110 mgm−2 yr−1) for watersheds that included pasture as well as forest.

Linkages between Terrestrial and Aquatic Ecosystems
TL;DR: In this article, the authors consider some of the ecological interactions and linkages that occur between land and water, and show the need for a comprehensive understanding of the intricate and complicated interactions.

The Impact of Soil and Fertilizer Phosphorus on the Environment
Andrew N. Sharpley,R. G. Menzel +1 more
TL;DR: In this paper, the impact of soil and fertilizer phosphorus on the environment is described and an increase in the amounts of soluble and particulate P transported in surface runoff have been measured after the application of fertilizer P. The detachment and transport of particulate phosphorus is also elaborated.
