Agronomists' C++ Toolkit: CWSI & Transpiration Biophysical Models

 

This post offers a starting point for sharing my embedded software code (GitHub repository: https://github.com/envitronicslab/CWSI_Function) in C/C++ used in a system you can learn more about here. While the full codebase needs some cleanup, I'm excited to share this initial, modular piece that calculates plant transpiration.

 𝗖𝗮𝗹𝗰𝘂𝗹𝗮𝘁𝗲𝘀 𝗮𝗰𝘁𝘂𝗮𝗹 (𝗧𝗮) 𝗮𝗻𝗱 𝗽𝗼𝘁𝗲𝗻𝘁𝗶𝗮𝗹 (𝗧𝗽) 𝘁𝗿𝗮𝗻𝘀𝗽𝗶𝗿𝗮𝘁𝗶𝗼𝗻: This code uses biophysical models to analyze microclimate and plant canopy surface temperature data to determine transpiration rates.

 𝗖𝗿𝗼𝗽 𝗪𝗮𝘁𝗲𝗿 𝗦𝘁𝗿𝗲𝘀𝘀 𝗜𝗻𝗱𝗲𝘅 (𝗖𝗪𝗦𝗜): Ta and Tp can be used further to calculate CWSI, an indicator of plant stress.

 𝗠𝗼𝗱𝘂𝗹𝗮𝗿 𝗮𝗻𝗱 𝗿𝗲𝘂𝘀𝗮𝗯𝗹𝗲: The code is well-organized with equations grouped within a class for easy integration into other projects.

 𝗘𝘅𝗮𝗺𝗽𝗹𝗲 𝗮𝗻𝗱 𝘁𝗲𝘀𝘁𝗶𝗻𝗴 𝗰𝗼𝗱𝗲: Additional code snippets are included in a separate module for demonstration and testing purposes.

𝗙𝘂𝗻𝗰𝘁𝗶𝗼𝗻𝗮𝗹𝗶𝘁𝘆 𝗮𝗻𝗱 𝗡𝗲𝘅𝘁 𝗦𝘁𝗲𝗽𝘀

This code is functional but not optimized. Further cleanup is planned. While initially developed for embedded software, the core functionality is also available in VBA. For those less comfortable with C/C++, I can provide guidance on adapting this code to Python.

The Rise of the "Human Data Farms": A Satirical Look at the Future of AI

Image
  The Data Dilemma The race for Artificial General Intelligence (AGI) has reached a fever pitch, with tech giants vying for dominance in the AI landscape. As Elon Musk has pointed out [1], the increasing scarcity of data for training AI models is a significant challenge. But as data becomes increasingly scarce, a new and perhaps more sinister solution is emerging: the rise of the "Data Farms." The "Human Data Farms" Concept Imagine a dystopian future where tech companies, desperate for the raw materials needed to fuel their AI models, begin constructing self-contained communities. These "Human Data Farms" would resemble a hyper-surveilled version of The Truman Show, where residents are paid handsomely to live their lives under constant observation. Every interaction, every conversation, every emotion – all meticulously recorded and fed into the insatiable maw of AI algorithms. Echoes of Reality This scenario, while seemingly absurd, has a chilling echo in ...

Understanding Plant Water Status: A Deeper Dive into VPD and Canopy Temperature

Image
After my recent post about the Hidden Complexities of VPD Measurements , and reading the comments, I realized I needed to provide more information on this topic. Let's assume we can obtain accurate canopy surface temperature data, target plant canopies are healthy (not affected by disease or pests), measurement timing is right, and we're dealing with a plant species that responds to VPD changes. Here are two key questions to consider: How should canopy surface temperature readings look like in a well-watered plant versus a water-stressed plant?   How can we take advantage of canopy temperature and VPD measurements?   Canopy-to-air temperature difference (ΔT = Tc - Ta) is fundamental. For most plant species responding to VPD, ΔT should be negative, signifying active transpiration. When plants close stomata due to water stress ( soil moisture deficit ), transpiration diminishes, and leaf surface temperature rises. Transpiration has a cooling effect on the leaf, similar to sweat...

Leveraging Microclimate Data, Proximal Canopy Sensing, and Machine Learning for Precise Soil Water Potential Prediction

Image
  Introduction Accurately predicting soil water potential is crucial for optimizing irrigation practices and minimizing water waste in agriculture. This project delves into the critical relationship between high resolution, in-field microclimate measurements, canopy surface temperature , time of day, and soil water content and potential. Building upon our previous work in biophysical modeling , we employ advanced machine learning techniques to investigate the impact of measurement timing on prediction accuracy. Enhanced Prediction with Machine Learning This project utilizes a range of machine learning algorithms, including: Linear Regression:  Establishes a linear relationship between features and target variables. Decision Tree Regressor:  Makes decisions based on a series of if-else questions. Random Forest Regressor:  An ensemble method combining multiple decision trees for improved accuracy and reduced overfitting. Gradient Boosting Regressor:  Iteratively b...
