The Energetically Autonomous Tactical Robot (EATR) was a project by Robotic Technology Inc. (RTI) and Cyclone Power Technologies Inc. in partnership with the University of Maryland, College Park's Center for Technology and Systems Management and Professor Bilal M. Ayyub. to develop a robotic vehicle that could forage for plant biomass to fuel itself, theoretically operating indefinitely.
A next level of analysis is to measure the growth allocation: what is the increase in total biomass of a plant, and to what extent is the increase due to growth of leaves, of stems and of roots. In young plants, growth allocation is often quite similar to the actual biomass allocation.
Arc Auxanometer. An auxanometer (Gr. auxain = "to grow" + metron= "measure") is an apparatus for measuring increase of growth in plants. [1]In case of an arc-auxanometer (see picture), there is a thin cord fixed to the plant apex on one end and a dead-weight on the other with a pointer indicating against an arc scale.
These key measurements are used for estimation of carbon sequestered in the plants. Forest structure measurement is needed for establishment of allometric equations. Tree allometry establishes quantitative relations between some key characteristic dimensions of trees ( usually fairly easy to measure ) and other properties (often more difficult ...
Equations used to describe plant size over time are then often expolinear [15] or sigmoidal. [16] [17] 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.
Leaf sensor technology developed by AgriHouse indicates water deficit stress by measuring the turgor pressure of a leaf, which decreases dramatically at the onset of leaf dehydration. Early detection of impending water deficit stress in plants can be used as an input parameter for precision irrigation control by allowing plants to communicate ...
A crescograph is a device for measuring growth in plants. It was invented in the early 20th century by Jagadish Chandra Bose. The Bose crescograph uses a series of clockwork gears and a smoked glass plate to record the movement of the tip of a plant (or its roots). It was able to record at magnifications of up to 10,000 times through the use of ...
Biomass (in the context of energy generation) is matter from recently living (but now dead) organisms which is used for bioenergy production. There are variations in how such biomass for energy is defined, e.g. only from plants, [8] or from plants and algae, [9] or from plants and animals. [10]
