You’ve decided to do something about your Eagle Mountain yard. Maybe it’s a new raised vegetable garden. Maybe it’s a lawn that’s been losing ground to bare patches for two summers. Maybe you’re landscaping from scratch on a lot that still looks like the construction crew left last week.
You go to order soil and hit a wall. There’s screened topsoil, composted horse manure, premium compost, organic blend topsoil, and something called Mountain Blend. They’re all different prices. The descriptions overlap. Which one do you actually need?
This post cuts through it. Each of the five products DIY Landscape Supply delivers to Eagle Mountain does a distinct job, and once you understand what that job is, the choice is usually obvious.
Before getting into individual products, it helps to understand the core distinction that runs through this entire category.
Some of these products are primarily about volume — adding depth and structure to areas that need more growing medium. Others are primarily about amendment — changing the biology, chemistry, and texture of soil that already exists but isn’t performing well.
Screened topsoil lives firmly in the volume camp. Premium compost is a pure amendment. The three blended products — Organic Blend, Horse Manure, and Mountain Blend — sit somewhere in between, combining both functions to varying degrees.
For Eagle Mountain specifically, where construction grading has left many lots with thin or nonexistent topsoil and the underlying soil is clay-heavy and alkaline, you often need both. A base layer of screened topsoil to build depth, followed by a compost or organic blend amendment worked into the top several inches, is the combination that addresses both problems at once.
Screened topsoil is the workhorse. It’s processed to remove rocks, clods, and debris, leaving a relatively consistent fine-to-medium textured soil that’s useful for a wide range of applications. At $29 per yard, it’s the most affordable product in the lineup and the right choice when you need volume.
Use it to fill low spots and level uneven terrain before seeding or sodding. Use it to build up bed depth above shallow or compacted subsoil. Use it as a base layer in new planting areas that will later get a compost amendment on top. What screened topsoil won’t do is transform alkaline clay soil on its own or give you a rich, high-nutrient growing medium for vegetables or premium plantings.
Best for: rough grading, fill, leveling, lawn prep on large areas where budget matters.
Horse manure mixed with wood shavings is one of the oldest and most effective soil amendments in the gardening world. The composting process breaks down the raw manure into a stable, odor-minimal organic material that’s rich in nitrogen, phosphorus, and potassium, while the wood shavings provide carbon and help maintain a balanced carbon-to-nitrogen ratio.
For Eagle Mountain soil specifically, horse manure compost is valuable because it reintroduces microbial life into depleted soil. Cedar Valley subsoil has almost no biological activity — working horse manure compost into the top 6 to 8 inches is essentially inoculating the ground with the organisms that make nutrients available to plants.
One note: horse manure is best used as an amendment worked into existing soil, not as a standalone growing medium. It’s high in salts relative to premium processed compost, and planting directly into it at high concentrations can burn roots. Mix it in at a ratio of roughly 1 part manure to 3 to 4 parts existing soil or screened topsoil.
Best for: vegetable garden bed preparation, tilling into lawn areas before reseeding, annual spring amendment for established beds.
This is a processed premium compost screened to half-inch minus — meaning every particle is under half an inch in diameter. That fine, consistent texture is the main selling point. It integrates smoothly into any soil type, works beautifully as a lawn topdressing, and mixes cleanly into raised bed blends without lumps or uneven patches.
Compared to horse manure compost, Premium Compost is more refined and more consistent batch to batch. It has high organic matter content, strong microbial activity, and a neutral-to-slightly-acidic pH that helps buffer Eagle Mountain’s alkaline conditions over time. It’s the most versatile amendment in the lineup — appropriate for lawns, gardens, raised beds, and tree and shrub plantings.
Best for: lawn topdressing, mixing into raised bed soil, annual bed amendment, any application where consistency and fine texture matter.
The Organic Blend is the bridge product between screened topsoil and premium compost. It’s a pre-mixed combination of topsoil and organic material, designed to function as a complete growing medium that you can plant into directly without further amendment.
At $75 per yard — the same price as Premium Compost but with significantly more volume value for large applications — the Organic Blend is the single-product solution for Eagle Mountain homeowners who want to fill a new planting area and be ready to plant without mixing anything. Pour it in, rake it level, plant. It won’t produce the same high-performance results as the Mountain Blend in a vegetable garden, but for ornamentals, lawn renovation, and general landscape beds it performs well.
Best for: new landscape beds, lawn renovation where both volume and nutrition are needed, any large-area application where all-in-one convenience matters.
The premium product. Mountain Blend is richer in organic matter than the Organic Blend, darker in color (which reflects higher carbon content), and formulated specifically for Utah’s high-desert, alkaline growing conditions. That last point is worth pausing on — this isn’t a generic bagged garden soil reformulated for the region. It’s built from the ground up for soil chemistry and climate challenges that are specific to Utah County and the Wasatch Front.
The price reflects the quality: at $125 per yard it’s more than four times the cost of screened topsoil and nearly double the Organic Blend. For filling a 400-square-foot vegetable garden 8 inches deep, that’s real money. But for homeowners who want to grow food seriously, install turf that will actually establish, or build planting beds that produce for years without constant amendment, Mountain Blend is the investment that pays off over time.
Best for: vegetable gardens, high-value planting installations, new lawn establishment where you’re building a real root zone, and any project where you want the best possible soil from day one.
| Product | Price/yd | Primary Use | Volume or Amendment | Plant Into Directly? | pH Buffering? |
| Screened Topsoil | $29 | Fill, leveling | Volume | With amendment | Minimal |
| Horse Manure | $45 | Soil amendment | Amendment | Mixed in only | Some |
| Premium Compost | $75 | Topdress, beds | Amendment | Yes (blend in) | Good |
| Organic Blend Topsoil | $75 | Beds, lawn areas | Both | Yes | Moderate |
| Mountain Blend | $125 | Vegetables, premium | Both (premium) | Yes | Strong |
Still not sure? Here’s the fast version:
Soil and compost are measured in cubic yards. One cubic yard covers 100 square feet at a 3-inch depth. For lawn topdressing at 1 inch, one yard covers roughly 300 square feet. For raised beds filled to 12 inches, a single 4×8 bed needs about 1.2 yards.

Can I mix screened topsoil and compost together?
Yes, and it’s one of the best strategies for Eagle Mountain yards that need both volume and biological improvement. A common ratio is 2 to 3 parts screened topsoil to 1 part compost — spread the topsoil, spread the compost on top, and till the whole thing together to 6 to 8 inches depth before planting or seeding.
Is horse manure compost safe for vegetable gardens?
Yes, when composted — raw manure is a different story, but composted horse manure has gone through enough biological transformation to be safe for food gardens. Don’t plant root vegetables directly in a heavy concentration of it; mix it into the surrounding soil at reasonable ratios.
What’s the difference between the Organic Blend and Mountain Blend?
Primarily organic matter concentration and formulation specificity. Mountain Blend is richer, darker, and built specifically for Utah’s alkaline, semi-arid growing conditions. The Organic Blend is a solid all-purpose product at the same price as Premium Compost. For vegetables and serious plantings, Mountain Blend is worth the price difference. For general landscape beds, the Organic Blend performs well and saves $50 per yard.
How many yards of compost do I need to improve a large backyard?
For a meaningful improvement at 1-inch topdressing depth across 2,000 square feet, you need about 6 yards of compost. That puts you in the 10-yard flat-rate delivery range if you combine it with a few yards of screened topsoil for fill areas — worth calculating together before ordering.
Does screened topsoil have compost in it?
Not specifically — screened topsoil is topsoil that’s been filtered for consistency, not amended with added compost. It has naturally occurring organic matter from decomposed plant material, but not at the concentrations of a dedicated compost product. That’s why the two products are often used together rather than one being a substitute for the other.
How does bulk delivery work in Eagle Mountain?
DIY Landscape Supply is delivery-only — no pickup available. Order online or by phone at (385) 321-3341. Most orders to Eagle Mountain are processed within 1 to 2 business days and delivered within 2 to 4 business days. Material is dropped in your driveway or wherever you specify on your property.
Is the Mountain Blend actually worth $125 per yard?
For a vegetable garden or high-value planting installation, yes — the difference in productivity between cheap fill soil and a well-formulated organic garden topsoil is significant. For a large general landscaping project where you need 15 or 20 yards of material, the Organic Blend at $75 is the more practical choice and still far superior to raw subsoil.
