๐Ÿงช Soil Organic Carbon Sequestration

Model SF8-S.001

Estimate soil carbon sequestration potential from conservation practices. Calculate COโ‚‚ equivalent offsets and time to reach target organic matter levels.

Typical: 1.1-1.5 g/cmยณ
Cover crops: 300-800; No-till: 200-500 lbs C/ac/yr

๐Ÿ’ง Soil Water Holding Capacity

Model SF8-S.002

Estimate plant-available water based on soil texture and organic matter. Calculate irrigation savings from improved soil health.

Typical: $5-15/acre-inch

๐ŸŒฑ Cover Crop Nutrient Credit

Model SF8-S.003

Estimate nutrient contributions from cover crop biomass. Calculate fertilizer replacement value for N, P, and K.

๐Ÿ”ฌ Soil Health Index

Model SF8-S.004

Composite soil health score based on biological, chemical, and physical indicators. Benchmarks against NRCS Soil Health standards.

Biological activity indicator
Water-stable aggregates
Lower is better. >300 psi = compacted

โ™ป๏ธ Nutrient Recycling Efficiency

Model SF8-S.005

Calculate nutrient use efficiency and recycling potential from crop residues, manure, and compost. Assess nutrient balance and loss pathways.

N returned to soil in crop residue
