photosynthesis from above for the time being the equipment is too heavy for drones to carry but they can still provide useful information for farmers. who worked on the ground measuring the crops with a yardstick it would be very time consuming to a few whereas if you use a drone it's done in minutes. the drone also gathers useful data from this trial field where future conditions are being simulated on the field seeds that formed in different years at different locations are being sprayed with c o 2 around the clock according to forecasts without action. atmospheric concentrations of the greenhouse gas are expected to double by 2050. its hopes the research will benefit farmers like they really claim a schillings climate change is putting them under intense pressure. to do well this is said to drought resistant variety won't be any good to us if we have an unusually wet year it could prove completely useless to what we need are varieties
