Grasses with trees

Rhizodegradation Soils, sediments, land application of wastewater Organic compounds (TPH, PAHs, BTEX, pesticides, chlorinated solvents, PCBs) Phenolics releasers (mulberry, apple, osage orange) Grasses with fibrous roots (rye, fescue, Bermuda) for contaminants 0-3 ft deep Phreatophyte trees for 0-10 ft Aquatic plants for sediments... 

Phytostabilization Soils, sediments Metals and metalloids (As, Cd, Cr, Cu, Pb, Zn, U, Se) Hydrophobic organics (PAHs, PCBs, dioxins, furans, pentachlorophenol, DDT, dieldrin) Phreatophyte trees to transpire large amounts of water for hydraulic control Grasses with fibrous roots to stabilize soil erosion Dense root systems are needed to sorb/bind contaminants... 

Garratt (1978) analysed data on heat transfer from a heterogeneous surface with high grass and trees (z0 = 0.4 m) and found that B l... 

On a lovely summer s day, when I was just six months old, my mother laid me down on the grass in the yard. A short while later I spent six months in the hospital with a very serious form of eczema (neurodermatitis). It was so bad they placed my arms in tubes so I could no longer scratch them. It turned out I was very allergic to grass and tree pollen, cats and all kinds of food products. I also developed asthma. 

All of the many biological transfer processes combine to determine a net surface resistance to transfer. Empirical relationships can be used to infer stomatal resistance from data on photosynthetically active radiation, water stress, temperature, atmospheric humidity and carbon dioxide levels. The resulting net surface resistance has been coupled with mathematical descriptions of aerodynamic and boundary-layer resistances in a "big leaf" model derived on the basis of agricultural and forest meteorology literature (4). At present, the big-leaf model is relatively coarse, permitting application only to areas dominated by maize, soybeans, grass, deciduous trees, and conifers.
