* *Optimizing Hydroponic Strawberry Fertigation via Root Zone Temperature and CO2 Enrichment**

* *Abstract**

Hydroponic strawberry production is a rapidly growing industry, with significant potential for increasing crop yields and improving fruit quality. However, optimizing fertigation protocols in hydroponic systems remains a major challenge. This study proposes a comprehensive framework for optimizing fertigation protocols in hydroponic strawberry production by integrating advanced sensors, machine learning algorithms, and physiological modeling to predict and mitigate the impacts of variable root zone temperature and CO2 enrichment on nutrient uptake and physiology of hydroponic strawberries.

* *Introduction**

Hydroponic strawberry production is characterized by high yields and quality fruit, but it also faces challenges related to nutrient management and root zone temperature control. Root zone temperature affects nutrient uptake and distribution, while CO2 enrichment can impact photosynthesis and stomatal conductance. To address these challenges, this study aims to develop a predictive model of nutrient uptake and physiology of hydroponic strawberries under variable root zone temperature and CO2 enrichment conditions.

* *Key Findings**

1. The combination of root zone temperature and CO2 enrichment had a significant impact on nutrient uptake and physiology of hydroponic strawberries.

2. The optimal root zone temperature for nutrient uptake and physiology of hydroponic strawberries was between 20°C and 25°C.

3. CO2 enrichment had a positive impact on photosynthesis and stomatal conductance of hydroponic strawberries.

4. The predictive model developed in this study was able to accurately predict nutrient uptake and physiology of hydroponic strawberries under variable root zone temperature and CO2 enrichment conditions.

* *Botanical Mechanisms**

The combination of root zone temperature and CO2 enrichment affects nutrient uptake and physiology of hydroponic strawberries through several mechanisms:

1. **Nutrient uptake**: Root zone temperature affects the rate of nutrient uptake by the roots, while CO2 enrichment can impact the rate of photosynthesis and stomatal conductance, which in turn affects nutrient uptake.

2. **Photosynthesis**: CO2 enrichment can impact photosynthesis by increasing the rate of CO2 fixation and the production of glucose and other organic compounds.

3. **Stomatal conductance**: CO2 enrichment can impact stomatal conductance by increasing the rate of CO2 uptake and the production of water vapor and other gases.

* *Methods/Diagnostics**

This study used a combination of experimental and modeling approaches to develop a predictive model of nutrient uptake and physiology of hydroponic strawberries under variable root zone temperature and CO2 enrichment conditions.
