This is very stressful and unthrifty. Likens et al. Calcium s relationship to other nutrients is shown in Table 1 for six east U.S. sites. This is what nourishes trout. They are about the same.
Harvesting has two major impacts on calcium capitals.
First, the calcium incorporated in the harvested products is carried away from the site. Second, for the first few years after harvest, there are no live tree roots to take up moisture and twice as much flow works its way through the site carrying away nutrients. Without shade bio-chemical activity is increased as it warms. As a result, more calcium leaches from the cut-over site, increasing the amount of dissolved calcium in stream flow or more often just maintaining its concentration in an increased flow. In North Carolina their calcium loss at clear cut was more than their normal annual loss of calcium.
