š§ **Assistant**
I'll help you explore the sockg knowledge graph. Let me start by getting information about this knowledge graph and its schema.
Great! I can now help you explore the **Soil Organic Carbon Knowledge Graph (SOCKG)**. This knowledge graph contains detailed agricultural experimental data focused on soil organic carbon, which is crucial for understanding carbon sequestration and climate-friendly farming practices.
## What's in SOCKG?
The knowledge graph includes:
- **Agricultural experiments**: Tillage events, crop rotations, fertilizer applications, soil measurements
- **Environmental data**: Weather observations, greenhouse gas flux measurements
- **Management practices**: Planting, grazing, irrigation, residue management
- **Soil samples**: Chemical, biological, and physical analyses of soil
- **Geographic coverage**: Sites across multiple locations with spatial data
- **Publications**: Research papers, reports, and bibliographic information
## Key Classes (105 total)
The schema includes classes for:
- Experimental units, treatments, and sites
- Soil samples (chemical, biological, physical)
- Agricultural management (tillage, planting, grazing, irrigation)
- Crops, cultivars, and cover crops
- Measurements (biomass, GHG flux, erosion, water quality)
- Weather observations
- Publications and research projects
## What would you like to explore?
I can help you:
- Find specific data about soil organic carbon measurements
- Explore relationships between management practices and outcomes
- Query experimental treatments and their effects
- Analyze spatial patterns across different sites
- Search for publications and research projects
- Examine specific crops, tillage methods, or amendments
What aspect of soil carbon research interests you?

Here's a visualization of the SOCKG schema showing the main classes and their relationships!
## Key Components:
**Core Experimental Structure:**
- **ExperimentalUnit** - The central entity containing treatments, measurements, and management practices
- **Treatment** - Experimental treatments applied to units
- **Site** - Physical locations where experiments are conducted
**Management Practices:**
- **TillageManagement** - Soil cultivation practices
- **PlantingManagement** - Crop planting details
- **GrazingManagement** - Livestock grazing activities
- **ResidueManagement** - Crop residue handling
- **Amendment** - Fertilizers and other soil amendments
**Data Collection:**
- **SoilSample** - Subdivided into chemical, biological, and physical samples
- **Measurement** - Quantitative observations with units
- **WeatherObservation** - Meteorological data
- **GHGFlux** - Greenhouse gas emissions
**Geographic Context:**
