09. Cover crops and diverse rotations

Field-supported, context-dependent

Keep living roots in the ground when a suitable season allows, and vary the crops that follow each other. Cover crops can serve different jobs: soil protection, nitrogen contribution, biomass, weed competition or a habitat bridge. Choose the species and termination method for the actual water budget and next crop. A practice that works in a humid vegetable rotation may use scarce moisture in a dryland grain system. [S13]

10. Reduced disturbance, with the whole system visible

Field-supported / operator examples

No-till can protect soil structure, yet the label says little about herbicide use, imported compost, plastic or labour. Compare a complete system. Singing Frogs Farm describes intensive ecological no-till vegetable production; the NRCS handbook provides a broader agronomic reference. The useful question is how a particular farm manages weeds, feeds crops, handles residues and earns its living while limiting disturbance. [S58] [S13]

11. Plant-based fertility and stockfree growing

Documented practice / certification routes

Green manures, legume rotations, plant composts and carefully selected amendments offer a serious route for growers who want fertility without livestock farming or slaughter by-products. Biocyclic vegan and Stockfree Organic give this intention an organised home. Plant-based inputs still need a nutrient budget: the crop removes nutrients, and the system needs an accountable way to replace them. Compassion and agronomy can be designed together. [S11] [S12] [S05]

12. Compost as a material with a history

Established agronomy

Ask what went into a compost, how it matured, how it was tested and how much phosphorus, salts and available nitrogen it adds. “More compost” is not a universal soil prescription. A plant-based farm can build a consistent compost stream and track its contribution over time. The aim is enough fertility for healthy crops while protecting water and avoiding a slow accumulation of unwanted materials. [S05] [S13]

13. Mycorrhizal relationships

Established biology; specific claims vary

Many plants exchange resources with mycorrhizal fungi, and some fungal networks connect multiple plants. The scale and significance of particular transfers require careful measurement. A 2023 critical review found popular “mother tree” stories often travelled beyond the supporting evidence. These relationships are already remarkable without assigning a human intention to every underground exchange. Protect habitat and investigate the actual plant–fungus partnership in front of us. [S10]

14. Microbial inoculants, indigenous cultures and JADAM

Mixed field response / living practice

In a 54-field Swiss maize study, mycorrhizal inoculation responses ranged from reduced growth to substantial improvement; soil microbiome indicators helped predict the response. That makes targeted use more interesting than a universal bottle recommendation. JADAM and other local microbial traditions offer additional farmer-led questions about cost, adaptation and nutrient cycling. Their practitioner reports describe practice; replicated local comparisons are needed to establish the particular benefits claimed. [S09] [S56]

15. Mineral balancing and remineralisation

Test-led agronomy

A soil can lack an essential nutrient even when it contains abundant organic matter. Begin with a suitable soil test, crop needs and local interpretation. Rock powders differ in chemistry, weathering rate and contaminants. Adding every mineral to every field can waste money and create imbalances. A more useful goal is correcting a demonstrated constraint and checking whether the crop, soil and water respond as intended. [S05]

16. Biochar and long-lived carbon

Evidence with material-specific tradeoffs

Biochar is produced by heating biomass under limited oxygen. Feedstock and production conditions influence its stability, chemistry and behaviour in soil. Potential benefits include particular soil and carbon-management outcomes, while contaminated feedstock, unsuitable pH or salts and production emissions can change the result. Treat biochar as a characterised material to test in a suitable setting. Its carbon story begins with where the biomass came from. [S14]
