Healthy soil isn’t built with one product, one practice, or one growing season. It’s built through a system.
Each principle has a video playlist for further discovery and how to put these principles into practice. Click and read below.
Farmers across the country face different climates, crops, and production challenges. Yet the biological processes that support healthy soil follow many of the same principles.
Understanding these principles gives growers a framework for evaluating management decisions and identifying opportunities to improve their operations.
At Ag Solutions Network, we encourage farmers to consider five (actually six) fundamental soil health principles.
1. Minimize Soil Disturbance
Every time soil is disturbed, its structure and biological environment can be affected.
Intensive tillage can disrupt soil aggregates, expose organic matter, and alter the habitat of beneficial organisms.
Reducing unnecessary disturbance helps preserve the physical structure of soil and supports the biological processes taking place beneath the surface.
For growers, this may mean reducing tillage passes, evaluating compaction, maintaining protective residue, or reconsidering management practices that unnecessarily disrupt soil biology.
The goal isn’t necessarily to eliminate every disturbance. It’s to understand its consequences and reduce it wherever practical.
2. Increase Biodiversity
Nature doesn’t operate as a monoculture.
Diverse plant communities create different root systems, biological interactions, and habitats for beneficial organisms.
Agricultural systems can benefit from introducing diversity through crop rotations, cover crop mixtures, flowering plants, and other management practices.
For example, a cover crop mix containing grasses, legumes, and broadleaf species can provide complementary functions.
Grasses may contribute fibrous roots and residue. Legumes can support biological nitrogen fixation through their relationships with rhizobia. Flowering species may provide habitat and food resources for beneficial insects.
The objective is functional diversity, not simply planting the largest possible number of species.
3. Maintain Continuous Living Roots
One of the most important relationships in agriculture happens where roots meet soil.
Through photosynthesis, plants capture sunlight and convert it into energy. Some of that carbon moves belowground through roots and root exudates, supporting microbial communities.
When fields remain bare for extended periods, that living-root contribution is interrupted.
Cover crops can extend the period of active plant growth between cash crops, helping support soil biology when the primary crop is absent or dormant.
In perennial systems such as orchards, carefully managed understory vegetation can provide additional living roots alongside the permanent crop.
4. Integrate Livestock Where Practical
Livestock can play a valuable role in nutrient cycling and vegetation management.
Managed grazing can return nutrients through manure, influence plant regrowth, and help manage cover crop biomass.
However, grazing must be managed carefully to avoid compaction, overgrazing, or damage to cash crops.
Not every farming operation can integrate livestock directly. Growers can still apply the broader principle by understanding nutrient cycling and exploring partnerships where appropriate.
5. Maximize Soil Cover
Bare soil is exposed soil.
Rainfall can dislodge soil particles. Wind can carry away valuable topsoil. Direct sunlight and high temperatures can accelerate surface drying.
Maintaining soil cover through living plants, crop residue, or mulch helps protect the soil surface.
In California, where water management is a constant concern, this principle deserves particular attention.
Cover crops can help protect orchard floors and improve soil conditions, although actively growing cover crops also use water. Their net water impact depends on timing, climate, species, and management.
How Cover Crops Connect the Five Principles
One of the reasons cover crops are such a useful management tool is their ability to support several soil health principles simultaneously.
They can provide living roots, introduce plant diversity, protect the soil surface, and support management systems that reduce unnecessary disturbance.
In some operations, they also provide grazing opportunities.
But cover crops are not a standalone solution. Their greatest value comes when they are integrated into a broader cropping system that includes thoughtful nutrition, water management, and field observation.
6. Surprise! There are six principles to consider:
Soil Health Is a Management Decision and Context is Everything
The five soil health principles aren’t a checklist that farmers complete once.
They’re a framework for continuous improvement.
A farmer may begin by adding a simple cover crop mixture, reducing a tillage pass, or maintaining more residue after harvest.
Those changes create opportunities to observe how the soil responds and make further adjustments.
The goal isn’t to farm exactly like someone else. It’s to build a healthier, more resilient system on your own acres.
