Understanding Soil Health
Healthy soil is alive with billions of organisms that cycle nutrients, suppress disease, and improve structure. Building soil health requires feeding soil biology, protecting soil structure, and maintaining organic matter levels.
Soil Testing and Analysis
Regular soil tests reveal nutrient levels, pH, and organic matter content. Test every 2-3 years and before making major amendments. Work with organic-focused labs that provide recommendations for biological fertility management.
Observe physical characteristics like aggregation, earthworm populations, and root penetration. These indicators often reveal soil health trends before chemical tests show changes.
Organic Matter Management
Organic matter stores nutrients, retains water, feeds soil organisms, and improves structure. Maintain levels above 3-5% through regular additions of compost, cover crops, and reduced tillage.
Apply 1-3 inches of quality compost annually to vegetable beds or targeted areas. Broadcast compost before rainfall or incorporate lightly to prevent drying out and loss of volatile nitrogen.
Soil Biology Enhancement
Diverse crop rotations and cover crops feed various soil organisms. Different plants exude different compounds that support distinct microbial communities, increasing overall soil biological diversity.
Minimize disturbance to protect soil structure and fungal networks. Use broadforks instead of tillers when possible, limit tractor traffic, and time field work when soil is properly dry to avoid compaction.
Nutrient Cycling
Organic nutrients release slowly as microbes break down organic matter. This gradual release matches plant uptake patterns, reducing leaching and providing season-long nutrition.
Use dynamic accumulators like comfrey and dandelion to mine deep nutrients and concentrate them in biomass for composting or mulching. Chop-and-drop mulching returns nutrients directly to soil.
