By Lauren Crawford on 29 May 2013*Soil moisture-controlled irrigation* is the future--but what does it look like *in practice*? Join Dr. John Lea-Cox for an example showing that *set-point control* leads not only to *water savings*, but also *Increased yields* *Improved quality* of the product A more *efficient and profitable* operation. This research is funded by USDA's Specialty Crop Research initiative.
By Dr. Steven Garrity on 23 May 2013Duration of leaf wetness is often used to estimate the risk of plant disease, alerting growers when to apply pesticide. Join Dr. Tracy Rowlandson for a virtual seminar where she explores methods for determining leaf wetness duration, discusses advantages and disadvantages of different estimation methods, and describes models used in disease warning systems.
By Dr. Doug Cobos on 24 April 2013Dielectric soil moisture sensors are used all over the world to measure soil water content for water balances, irrigation scheduling strategies, and other plant-soil-atmosphere continuum studies. However, understanding how the instruments actually measure soil moisture will greatly enhance your ability to interpret your data.
By Dr. Colin Campbell on 3 April 20138:00 AM PST Dr. Campbell, an environmental biophysicist at Decagon specializing in soil moisture instrumentation, will give an overview of the different methods to measure soil water content, discuss the theory behind the measurement, provide examples of field research and what technology might apply in each situation.
By Jordan Tanasse on 28 March 2013NDVI & PRI: Measurement Theory, Methods, and Applications NDVI (the normalized difference vegetation index) is correlated with biomass, canopy structure (eg. , LAI), and foliar chlorophyll content. PRI (photochemical reflectance index) is emerging as a useful vegetation index for estimating plant canopy photosynthetic light use efficiency.
