I needed this for a
project and it took me some time to compile.
I used The Dan Kittredge Amendments mostly, another post, but added in some things because we had really poor soil
water holding capacity.
Mostly Zeolite (7 tons) and
BioChar (3 tons) per acre. Won't know the results for couple years probably.
List of Soil natural non-salt Amendments and Benefits :
Compost
Enhances soil structure and water retention.
Adds nutrients (N, P, K) and boosts microbial activity.
Improves fertility and promotes healthy plant growth.
Manure
Supplies organic matter and nutrients (N, P, K).
Improves soil texture and microbial activity.
Increases fertility and supports vigorous plant growth.
Biochar
Improves soil porosity and water retention.
Sequesters
carbon and reduces nutrient leaching.
Enhances soil health and supports
sustainability.
Gypsum
Reduces soil compaction and improves structure.
Provides calcium and sulfur for plant strength.
Enhances water infiltration and
root growth.
Lime
Raises soil pH and improves nutrient availability.
Supplies calcium and enhances soil structure.
Promotes microbial activity and plant growth.
Dolomitic Lime
Raises pH and provides calcium and magnesium.
Improves nutrient availability and soil structure.
Supports photosynthesis and healthy growth.
Rock Phosphate
Supplies slow-release phosphorus for
roots.
Enhances flowering and soil fertility.
Supports
energy transfer in plants.
Greensand
Provides potassium, iron, and trace minerals.
Improves soil structure and fertility.
Enhances plant resilience and health.
