Fate and Transport of Nutrients: Nitrogen | NRCS

Anhydrous ammonia, or gaseous NH 3, is a very important direct-application N-fertilizer.Gaseous NH 3, when in contact with moist soil, dissolves in and reacts with soil water to form NH 4 + and OH-ions. The pH is increased dramatically immediately around the application zone of anhydrous NH 3.Therefore, depending upon the buffering capacity of the soil and the resulting soil pH, an equilibrium

PDF) A stem-boring moth drives detritus production in SW

In marshes, the phenology of plants deter- mines the timing of tissue death and the amount of detritus production (this tissue is added to the de- trital pathway; Hardisky & Reimold 1977), whereas physical forces (e.g. tidal flooding) transport detritus between ecosystems.

These distinct compounds are useful for assessing diagenesis that can occur during river transport of organic detritus. Poaceae, mainly Gramineae and Elaeis guineensis higher plant species, are proposed as primary sources for the PTMEs and esters in the sediments. PTMEs are biomarkers of specific higher plant subspecies, while the triterpenol

Bedload and nearbed detritus transport in a tidal saltmarsh creek

nearbed transport through the creek was estimated to be less than 0.2% of the estimated annual above- ground plant biomass production in the drainage area of the creek. Therefore, it is concluded that this type of detritus transport is probably ; detritus

PDF Particulate Phosphorus in the Everglades Agricultural Area: II—Transport Mechanisms - EDIS

The normal transport mode for dense mineral sediments found in upland drainage systems is movement by saltation as bed load along the channel bottom. This transport mode is not the case in the EAA. Here, the transported solids are typically light, floc- culent, and mobile, moving as suspended load distributed throughout the water column.

2010/10/12 · Most agricultural watersheds in the Midwest consist of channelized stream networks that rapidly accumulate and transport water, along with associated solutes and detritus (7, 12–14). These watersheds typically have a high drainage density ( 15 ), with numerous headwater streams ultimately draining into the Mississippi River or the Great Lakes.

Detritus | ecology | Britannica

Many freshwater streams have detritus rather than living plants as their energy base. Detritus is composed of leaves and other plant parts that fall into the water from surrounding terrestrial communities. It is broken down by microorganisms, and the microorganism-rich detritus is eaten by aquatic invertebrates, which are in
