Precision Horticulture & Soil Mechanics Lab
Deterministic, formula-driven web tools for modern gardeners, homesteaders, and urban growers. Calculate raised bed soil volumes with true settling physics, balance thermophilic compost C:N ratios by dry weight, and engineer drip irrigation grids.
Raised Bed Volume, Settling & Blend Optimizer
Calculates cubic yards, cubic feet, and standard bag counts for rectangular, round, and corner beds. Incorporates 15%–22% substrate compaction and Hugelkultur woody base displacement.
Calculates cubic metres, litres, and 25L/50L bag counts for rectangular, round, and corner beds. Incorporates 15%–22% substrate compaction and Hugelkultur woody base displacement.
30:1 Compost C:N & Moisture Balancer
Converts real-world 5-gallon bucket volumes into scientific dry-mass Carbon-to-Nitrogen ratios. Balances spent coffee grounds, manure, cardboard, and leaves for optimal thermophilic heating.
Converts real-world 20-litre bucket volumes into scientific dry-mass Carbon-to-Nitrogen ratios. Balances spent coffee grounds, manure, cardboard, and leaves for optimal thermophilic heating.
Drip Irrigation Emitter, GPH & Timer Calculator
Translates agronomic target water depth (inches per week) into exact controller run-time minutes. Calculates total GPH line load and matches emitter spacing to soil wetting bulb mechanics.
Translates agronomic target water depth (mm per week) into exact controller run-time minutes. Calculates total LPH line load and matches emitter spacing to soil wetting bulb mechanics.
Transparent Botanical Engineering & Scientific Standards
LoamCalc was founded on a simple principle: Gardening advice should be as mathematically rigorous as structural engineering. Rather than offering vague suggestions like "add a few handfuls of compost" or "water twice a week," our tools model the underlying physical equations and chemical stoichiometry:
Physical Bulk Densities & Moisture Fractions
Every feedstock and soil component has a distinct bulk density (dry mass per cubic foot) and inherent moisture fraction. We calculate true dry chemical mass so that airy shredded cardboard is never confused with dense poultry manure.

Settling Compaction & Pore Collapse
Newly blended substrates inevitably settle 15% to 22% after first overhead saturation as organic fibers consolidate. Our calculators ensure your bulk orders arrive with adequate compaction buffer, preventing hollow beds.
Hydraulic Wetting Bulb Mechanics
Capillary forces pull irrigation water horizontally while gravitational hydraulic gradient pulls downward. Our irrigation algorithms adapt line intervals and session run-times to your specific soil texture class.
Agronomic Peer Citations & Theoretical Grounding
LoamCalc tools derive their coefficients from peer-reviewed horticultural and environmental standards, including the USDA Natural Resources Conservation Service (NRCS) Soil Survey Field Handbook, the Cornell Waste Management Institute Compost Fact Sheets, and the United Nations FAO Irrigation and Drainage Paper No. 56.
How to Use the LoamCalc Platform for Optimal Results
For new garden installations, we recommend beginning with the Soil & Raised Bed Lab to compute your raw timber geometry, subtract Hugelkultur woody displacement, and apply the appropriate consolidation allowance before placing bulk soil orders.
Next, utilize the Drip Irrigation Hydraulics Lab to design your lateral tubing manifold, ensuring line flow stays safely beneath your outdoor hose bibb capacity while delivering the required precipitation depth without soil crusting or runoff.
Throughout the active growing season, turn to the 30:1 Compost C:N Balancer to recycle kitchen scraps, coffee grounds, and carbonaceous brown yard waste into living biological humus, converting real-world container measurements into balanced thermophilic heaps.
