Mineral Cycling And Productivity In An Upland Deciduous Forest: Soils And Methods, Nicholas P. Kobriger
Mineral Cycling And Productivity In An Upland Deciduous Forest: Soils And Methods, Nicholas P. Kobriger
Field Station Bulletins
This study was designed to improve our understanding of the dynamics of the upland forest and of the productivity of Wisconsin forest communities. Data were collected to quantify the biological cycling of nutrients, nutrient availability and water availability, the principal factors supporting production of organic matter in forest ecosystems (Duvineaud and Denaeyer-De Smet, 1970). Using the data from this study we can then examine the stability of the upland deciduous forest and its response to the environment, for example recovery from a catastrophic event such as the March ice storm. Once this ecosystem's structure and functioning are known, we can …

Effect Of Topdressing Different Forms Of Nitrogen Fertilizer On Corn, Doyle Peaslee, Morris J. Bitzer, Harold F. Miller
Agronomy Notes
Nitrate nitrogen is the dominant form of plant-available nitrogen in soils, since even ammonium nitrogen is rapidly converted to nitrate nitrogen under Kentucky field conditions. Nitrogen in the nitrate form can be lost by leaching in the drainage water and by denitrification when the soil is saturated with water for a relatively short period of time. With the increased cost and short supply of nitrogen fertilizers, it is especially important that applications be made at a time and in a way that will minimize losses.
