Agronomic studies often focus on the above-ground part of plant biomass, and consider crop growth rates rather than individual plant growth rates. Nonetheless there is a strong corollary between the two approaches. More specifically, the ULR as discussed above shows up in crop growth analysis as well, as: = . = .
Cross section of a slope with soil nails installed. Soil nailing is a remedial construction measure to treat unstable natural soil slopes or unstable man-made (fill) slopes as a construction technique that allows the safe over-steepening of new or existing soil slopes.
When stocking, a tree's basal area is measured. The basal area is a cross-sectional area of the stump taken about 4.5 feet (1.4 m) above the ground. [7] The equation for calculating the basal area of trees in a stand is Basal Area = 0.005454 DBH 2, where DBH is the diameter of the tree at the aforementioned measuring height. [7]
PAI may go negative if a tree loses volume due to damage or disease. Periodic annual increment is commonly used instead of current annual increment as a basis for computing growth per cent . Growth per cent indicates the rate of increase with relation to the wood capital required for its production, this is usually based on a single year's growth.
A Canarium strictum tree in red leaf flush. Leaf flushing or leaf out is the production of a flush of new leaves typically produced simultaneously on all branches of a bare plant or tree. Young leaves often have less chlorophyll and the leaf flush may be white or red, the latter due to presence of pigments, particularly anthocyanins . [ 1 ]
On an average day nearly 303 million US gallons (1,150,000 m 3) of water flow from Big Spring in Missouri at a rate of 469 cubic feet per second (13.3 m 3 /s). Grand Prismatic Spring, Yellowstone National Park, Wyoming. A spring is a natural exit point at which groundwater emerges from an aquifer and flows across the ground surface as surface ...
Eriophyes tiliae is a mite that forms the lime nail gall or bugle gall. [2] It develops in a chemically induced gall ; an erect, oblique or curved distortion rising up from the upper surface of the leaves of the lime (linden) trees (genus Tilia ), such as the large-leaved lime tree Tilia platyphyllos , the common lime tree Tilia × europaea , etc.
A eucalyptus plantation in final stages at Arimalam.. The type of tree planted may have great influence on the environmental outcomes. It is often much more profitable to outside interests to plant fast-growing species, such as eucalyptus, casuarina or pine (e.g., Pinus radiata or Pinus caribaea), even though the environmental and biodiversity benefits of such monoculture plantations are not ...
