📘 Introduction

Respiratory Activity is a desktop application for calculating the soil’s respiratory activity (SRA). It was developed primarily for laboratory research at Kazan Federal University. 🌍

The app supports four different methods of SRA measurement:

• 🧪 In-lab via gas chromatograph
• ⚗️ In-lab via titration
• 🌿 In-field via gas chromatograph
• 🍃 In-field via CO₂ analysis

Additionally, you can process and calculate SRA directly from Excel tables using a dedicated menu. 📊
