The Organic Gardener's Guide to Manure, Compost, and Soil Building (Part 2)

Manure quality varies wildly—"what goes in comes out." Understanding sources transforms your soil building.

Manure Nutrient Hierarchy

• Top tier: Rabbit, chicken (seed/grain-fed → high minerals, C/N ~8:1)
• Excellent: Alfalfa-fed rabbits (C/N ~12:1)
• Very good: Spring grass, quality hay, leafy greens
• Good: Grain-supplemented dairy cows (high production demands)
• Poor: Straw-bedded horses on mature hay from depleted soil (C/N 50-60:1, barely heats)

Bedding Impact

Sawdust bedding dilutes manure severely. Straw bedding richer (often dairy origin). "Short manure" (no bedding) prized historically; "long manure" (with bedding) less valuable.

The Urine Factor

Over half of animal excretion is urine—rich in nitrogen, complex organics, cellular compounds that feed soil ecology. Hard to capture (leaches/runoff). Poultry excels: liquid + solid uniformly mixed = zero loss.

Paper in Compost

Nearly pure cellulose (high C/N like straw). Valuable bulk for mulch-compost. Must shred—whole sheets form impermeable mats. Hand-tear newsprint along grain; hammermill for volume.

Historical Perspective

Pre-chemical farmers hauled produce to market, returned with "street sweepings" (horse manure). They understood nutrient cycling intuitively.

Master these nuances, and your compost becomes precision nutrition for living soil.
