A recent study explored the potential of RS data and ML models for predicting almond yield. The study evaluated various RS platforms, including MODIS Terra LST, GSMaP, Landsat 8, Sentinel-2, and PlanetScope. The study found that irrigation data, daily temperature, NDVI, and SAVI derived from PlanetScope showed the highest predictive performance, achieving an impressive R² value of 0.80. Interestingly, irrigation and daytime temperature were identified as the most important features for predicting almond yield, highlighting the pivotal role of water and temperature in crop growth and development. If you're interested in learning more about how satellite data can enhance crop yield and farm productivity, feel free to reach out! #RSdata #MLmodels #agtech #satellitedata #cropyield #farmproductivity https://lnkd.in/g4xsnCxY

Fully automated analysis are a core of Spaceknow capabilities....
SpaceKnow Inc. provided timely imagery and analysis capturing the devastation of the Kakhovka Dam in Ukraine—an appalling act orchestrated by Russian occupation forces. The deliberate destruction of this vital infrastructure, which served as a lifeline for both people and agriculture across the region, has led to severe repercussions. The loss of the dam has resulted in a devastating shortage of potable water and disrupted agricultural irrigation systems, exacerbating the suffering of civilians and further damaging the fragile natural environment. Using our AI-driven analytics, SpaceKnow now presents enhanced imagery to offer insights into the current condition of the Kakhovka Dam. In NDVI imagery, vibrant red shows thriving, chlorophyll-rich vegetation, while dull green tones suggest areas of dry or stressed fields. #satelliteimagery

Dragonfly Aerospace imagers onboard #EOSSAT_1 captured 🇨🇦 #Canada’s circular fields that look out of this world, revealing the beauty at its finest! And although some might compare them to the infamous “crop circles”, we are quite certain this time these are real fields in Alberta captured by our satellite. 💧 The thought-provoking field geometry owes its perfect circular shape to center-pivot irrigation – a method that’s especially in demand in arid regions where it helps maximize crop yields while preserving limited water resources. #Sustainability in action! 🚰 The #CenterPivotIrrigation system consists of a long water-pumping tube with sprinklers and wheeled towers that pivot around the water source in the field’s center and spray water on crops as they go. That explains the concentric circles that can be seen on zooming in: those are wheel tracks. It’s delightful to see how #sustainability shapes a better, more beautiful world through advanced farming technology – and even more delightful to see it from space. Stay tuned for more enigmatic #Earth images from #EOSSAT-1 with its powerful DragonEye imagers: https://bit.ly/4964wnU

Just how accurate is OpenET? The online mapping tool, based on Landsat and other satellite data, helps track and manage water use such as irrigation in the western United States. Below OpenET map shows the cumulative evapotranspiration using an ensemble of six models for the Bakersfield, California, area, with the highest amounts in dark blue.

🌲 In our #SkyWardForests collection, we also consider #DroneImagery, which can be equally effective in monitoring forest conditions. 🔍 In the example below provided by #ForwardsEU partner Eidg. Forschungsanstalt WSL, different colours identify the Photochemical Reflectance Index in an experimental irrigation site in Pfynwald: the Index detects #drought stress in trees thanks to multispectral sensors not visible in normal photography.

ABSTRACT USE OF GROUND PENETRATING RADAR IN MAPPING AND ASSESSING TREE ROOT SYSTEMS Ground Penetrating Radar (GPR) when combined with software that includes geophysical algorithms to process survey data and map subsurface structures provides a valuable non-invasive, non-destructive tool for assessing tree root growth in situ. The use of the novel TreeRadarTM software has been explored in urban forestry to develop high- resolution, non-invasive images of root systems, allowing for quantitative analysis of urban tree health and structural integrity. The objective of this study was to assess the feasibility of using the Ground Penetrating Radar (GPR) in combination with this proprietary TreeRadarTM system software for use as a reliable non-destructive root locator and size estimator. The study was conducted for several years at different sites and on different trees. Results from this study indicate that the GPR/TreeRadarTM system has good potential for use in root locating as there was a very strong correlation between projected and actual root location (R2 = 0.95). Thus, broader adoption of this technology has the potential to greatly enhance our ability to better understand root response(s) to modified cultural practices including canopy management, fertility, and irrigation. In addition, the predictive ability of this technology to non-destructively map root systems either via 2D trench, or 3D morphology models has broad applications, including risk analyses, assessing interaction with the built environment (roadways. underground utilities, building foundations. levee walls, etc.

Why infiltration rate is so important? 🚿 💧 The downward movement of water from the ground surface to the soil profile is known as infiltration and is a crucial part of the water cycle. 🌧 🏖It is essential for designing irrigation and drainage systems, evaluating groundwater recharge, investigating and modelling subsurface flow and contaminant transport, and designing and modelling hydrologic systems. 💧 The infiltration rate depends on soil characteristics such as soil texture, hydraulic conductivity, soil structure, vegetation cover and rainfall. 🌳 This study was conducted at agroforestry system for compare the validity of various infiltration models with observed values from double ring infiltrometer. 📑 From the results the Kostiakov's model performed better than the Horton and Phillip models in order to an agroforestry system. 📜 The Kostiakov's model might be used to generate infiltration information for an agroforestry system in the absence of measurable infiltration data. #Soilquality #Soilphysical property #Infiltration rate #Infiltration models #Kostiakov #agroforestry
