#SMART4D Zone Management System allows for efficient, high resolution soil variability mapping without time-consuming terrestrial-based sensor mapping

What #NDVI tells us:
Relative differences in chlorophyll content
What it doesn't:
Nutrient status, moisture stress, disease incidence, compaction, soil organic matter, nutrient use efficiency, etc
#BeyondNDVI #4DAgronomy
What are some of the real-world applications of high resolution #Imagery in #PrecisionAg?

3D Relative Biomass
Unlike #NDVI, these models actually account for height variation in estimating relative differences in biomass.
#BeyondNDVI #RemoteSensing #Photogrammetry #PrecisionAg
Multi-year analysis of #NDVI actually had a respectable correlation to gravimetric moisture (0.55) at 1/4 acre grids, but the 3D overlay illustrates why we still prefer zones based on high resolution #Soil data to reduce ambiguity.
#BeyondNDVI #PrecisionAg #Imagery
#NDVI based zones were used to vary seeding rates (left image).
More biomass doesnt mean increase seeding rates, especially in a #WhiteMold microenvironment in #Soybeans
Right map shows yield decline in that region; rates should have dropped, NOT increased there.

High Resolution #Soil Mapping
Compare soil data point density between: 2.5 acre grid, EC 40 ft swath & soils #Imagery (RSM) 9 ft resolution.

Great explanation by Jean-Baptist’s Feret @irstea on biophysical vegetation parameters from #RemoteSensing. #beyondndvi #RTM #prosail #Sentinel2 #ECPA2019 @multiply2020 #agronomics
Same row, hybrid, planting date, ssurgo map unit, etc. DIFFERENT microenvironments delineated using #SMARTZones
No grids, yield maps, ground-driven sensors, etc. Just properly timed #RemoteSensing #AgData #BeyondNDVI
Looks like an excellent platform for collecting imagery & topo at high resolution!
Love the five bands; makes this a versatile mapping solution for #beyondNDVI as well as conventional plant health indices.
#RedEdgeMX + #eBeeX: The sensor that doesn’t compromise meets mapping without limits. Our most requested integration package is now available from our partners at @sensefly!

#BeyondNDVI 3D biomass model of 120 acres of corn at tassel.
Height of the crop is isolated and visualized without the influence of topography. Colorized map is reflectance-based plant health (red is bad, purple is healthiest).

#BeyondNDVI
Imagery used to map soil moisture. More water means more time before soils warm up, affecting maturity as seen here.
#BeyondNDVI Even across dramatically different soil types, our analysis shows consistent correlation to organic matter & exchange capacity!
