Caliche isn't soil yet. We build the rest.

Compost. Biochar. Worm castings. KNF inputs (FPJ, WCA, OHN, IMO). The work that turns Hill Country caliche into the topsoil your plants actually want.

Compost · biochar · KNF · organic fertilizer No synthetics

Most caliche properties get bagged topsoil dumped on top — raised beds floating on stilts. Those investments don't last.

Building soil is the slow, compounding investment that makes every other landscape decision easier. Plants establish faster. Water moves down instead of off. Pest pressure drops. Drought resilience compounds year over year.

Noon's soil program is the work that should have happened before anything else. It's based on real organic methods — compost, biochar, worm castings, Korean Natural Farming (KNF) inputs like Fermented Plant Juice and Indigenous Microorganisms. No synthetic fertilizers. No quick-release nitrogen. No spray-and-pray.

§ 1 · How we build soil

Three years to real soil.

Soil is built, not bought. The program below is what we run on properties with caliche, clay, or depleted urban fill. By year three, most properties have 6+ inches of biologically active topsoil where there used to be a calcified cap.

If you're starting a food garden, you're going to need this work whether you do it now or scramble to do it later. If you're installing a native landscape over caliche, the soil program is what determines whether the install thrives or just survives.

§ 2 · What's included

Real inputs.

Included
Compost delivery + spread
Aged hardwood compost, locally sourced. 2-3 inch top-dress. The foundation of every program.
Included
Biochar (mesquite or oak)
Locally pyrolyzed. Pre-charged with compost tea. Permanent soil structure improvement.
Included
Worm castings
Locally produced (Texas worm farms). Slow-release nutrients + biology. Used in planting holes.
Included
KNF input program
Weekly application of FPJ, WCA, OHN, IMO. Build the microbial population that does the work.
Included
Compost tea brewing
On-site aerated compost tea. Drench beds + foliar feed.
Included
Organic fertilizer (when needed)
Fish emulsion, kelp, alfalfa meal. No synthetics. No quick-release N.
§ 3 · Pricing

Honest pricing.

Soil work prices by yards of material + labor + program complexity. Most clients start with one zone (front yard, back yard, garden) and add others as they see the results.

Single zone start
$800-$2,000
1,000-2,500 ft² · 2" compost top-dress + biochar in beds + 1 KNF application
Annual program
$2,000-$5,000
Whole property · seasonal compost + biochar where needed + weekly KNF + cover crops
Garden + estate
$5,000-$8,000+
Food garden setup + lawn-to-meadow + multi-year program with bed installation
§ 4 · Why not synthetic

Why not synthetic fertilizer?

Synthetic fertilizers — Miracle-Gro, weed-and-feed, granular NPK — work fast and look like they work. They also burn out soil biology, salt-load the soil over time, push nitrogen-rich tender growth that pests target, and create dependency. The plant gets fed; the soil gets poorer.

Organic and biological inputs work the other direction. They feed soil biology first, soil biology feeds the plant. Slower start. But after one season the soil is measurably better. After three, it's a different soil entirely.

Synthetic fertilizers are the equivalent of feeding your kid Soylent. They get the macros. They don't get a microbiome. Plants need their microbiome too.

§ 6 · FAQ

Common questions.

What's the best soil amendment for caliche?
Compost, layered over time. Not bagged topsoil dumped on top. The compost top-dress (2 inches annually, ideally in fall) builds biologically active soil that breaks down the caliche cap from above and provides the structure plants need. Biochar (5-10% in planting holes) gives permanent structural improvement. KNF inputs build the microbial population that powers the system.
Is compost better than fertilizer?
Yes, for long-term soil health. Synthetic fertilizers feed the plant directly but burn out soil biology, salt-load the soil, and create dependency. Compost feeds soil biology first, soil biology feeds the plant. After 2-3 seasons of compost program, plants need almost no fertilizer at all — the soil does the work.
What is KNF and does it work?
Korean Natural Farming. A set of farm-made organic inputs developed by Cho Han-Kyu: Fermented Plant Juice (FPJ), Indigenous Microorganisms (IMO), Oriental Herbal Nutrient (OHN), Water-soluble Calcium (WCA), Lactic Acid Bacteria (LAB). All made from local plants and water. Used by organic farmers globally. Real microbial inoculation that builds soil biology fast. We make them on-site for client properties.
What is biochar and why do I need it?
Biochar is pyrolyzed wood (basically charcoal made in low-oxygen kilns). When charged with compost or worm castings, it becomes a permanent home for soil microbes — high surface area, high cation exchange. 5-10% in planting holes gives lifetime structural improvement to caliche soil. Mesquite is our preferred feedstock locally.
How much compost do I need?
For top-dressing established beds, 2 inches annually = 1 cubic yard per ~160 ft². For amending caliche (new beds), 4-6 inches mixed into top 12 inches = 1 yard per ~50 ft². Our free Material Estimator calculator does the math from your bed dimensions.
How much does a soil program cost in San Antonio?
Single-zone start (2,000-2,500 ft² with compost top-dress + biochar in beds) runs $800-$2,000. Annual whole-property program is $2,000-$5,000. Garden + estate-scale with multi-year program: $5,000-$8,000+. Most clients see real soil improvement by month 6 and dramatic improvement by year 3.
