“New Type” Forest Declines and Restabilization/Revitalization Strategiess focused on the specific application of nutrients, particularly in stands with acute nutritional deficiencies. This is accomplished by means of readily soluble Mg and K fertilizers at application rates of 500 to 1,000 kg·ha..

Effects of Lake Liming on Phytoplankton Production in Acidic Adirondack Lakess associated with lower chlorophyll levels during the first summer after treatment. Reductions in chlorophyll levels at L. Simon Pond reflect the absence of the spring phytoplankton peak and a decrease in phytoplankton growth below the depth of the thermocline. At Cranberry Pond, annual differences摇摆 发表于 2025-3-25 20:30:57

Differences in Pre- and Post-Treatment Water Qualities for Twenty Limed Lakes fact that most of the limed lakes in this study were only mildly acidic prior to liming and concentrations for many metals were near detection limits. Comparison of pre- and post-treatment water quality conditions in these lakes indicates that liming was successful in improving water quality conditions for fisheries.annexation 发表于 2025-3-26 15:05:08
