2) Estimation of nitrogen and phosphorus loads from of source strength estimates.<br />
Given the incomplete information about the various existing sources, estimation of this sort<br />
cannot be done without substantial simplification and generalization. In essence it involves<br />
making maximum use of those data that have most bearing on generation of nitrogen and<br />
phosphorus, i.e., population and agro-industrial activity. An index for the latter, which reflects the<br />
degree of modern agricultural development, is the amount of fertilizers used/ha agricultural land,<br />
whereby the precise specification of the kind of crop and crop land in question and the<br />
composition of fertilizers used must remain open.<br />
Point Sources: domestic and related sources. Figures about the metabolic production<br />
of nitrogen and phosphorus by the resident population are among the most reliable for estimating<br />
total source strength. Estimates about other sources without extended measurement<br />
programmes, on the other hand, are affected by large uncertainty margins. Nitrogen and<br />
phosphorus produced by a population of 154 million amount to some 680,000
