Tillable vs Total Acres
Definition
Total acres are the full deeded area of a farm parcel. Tillable acres are the portion that can be cropped and is rented for crops; the rest may be farmstead and building sites, timber, pasture, grassed waterways, terraces, ditches, roads and rights of way, wetlands, or land enrolled in conservation programs. Because rent, yields and soil productivity apply to tillable acres, comparisons of price, rent and soil quality are most meaningful per tillable acre. A price quoted per total acre looks lower on a farm with many non-tillable acres, while a price per tillable acre ignores whatever value the non-tillable land has, such as a homesite, hunting, timber or conservation payments. The ratio of tillable to total acres is itself a quality signal: a high ratio usually means a cleaner, more efficient field.
Why it matters
Farmland marketing quotes 'price per acre' constantly, and the acre basis is often unstated. The difference between total and tillable acres can move a farm's apparent price, rent yield and soil rating by several percent or much more on irregular parcels. Rent is paid on tillable acres, so a rent-per-acre figure on tillable acres divided by a price on total acres overstates yield. For investors comparing fractional farm offerings with each other or with local sales, putting every figure on a tillable-acre basis, and valuing the remainder separately, is the simplest way to compare like with like.
Common misconceptions
- •An acre is not always an acre. Prices, rents and soil ratings should state their basis.
- •A lower price per total acre is not necessarily cheaper. Non-farmed acres may be the reason.
- •Non-tillable acres are not always worthless. Building sites, timber and energy leases can carry value.
- •Soil ratings should not average in non-farmed land. Weight them over tillable acres.
- •Mixing bases inflates yields. Rent per tillable acre over price per total acre overstates income return.
Technical details
Worked example: AcreTrader's Argyle Farm
Total acres: 145.90; tillable acres: 142.8 (97.9% tillable).
Price: $892,500 = $6,250 per tillable acre, about $6,117 per total acre.
Rent: the pro forma rents 143 acres for $32,130 a year ($225 an acre), a 3.60% gross yield on the price.
A high tillable share means the two bases are close; on a farm with 75% tillable, they would differ by a third.
Typical non-tillable uses
Farmstead, buildings and grain storage sites.
Timber, pasture and wetlands.
Grassed waterways, terraces, ditches and field borders.
Roads, rights of way and utility easements.
Land enrolled in conservation programs.
Checklist
Confirm tillable acres from FSA records, the lease and the soil map.
Restate price, rent and soil index per tillable acre.
Value non-tillable acres separately, with any income they produce.
Check that comparable sales are on the same basis.
How investors apply the term
Investors usually apply this term by tying the definition back to the controlling documents and then asking which cash flows, rights, restrictions, or valuation assumptions it changes. A useful review looks at the term alongside fees, leverage, liquidity, reporting frequency, and manager discretion rather than treating it as a standalone concept.
The practical diligence test is simple: identify who benefits if the assumption is wrong, who has control when conditions change, and what evidence the investor receives after closing. Terms that cannot be reconciled to documents, cash movements, and monitoring data should be treated as marketing shorthand until proven otherwise.
Frequently asked questions
- Should farmland price per acre use total or tillable acres?
- Use tillable acres to compare cropland value, rent and soil quality, because those acres earn the rent. Then add a separate value for any non-tillable acres that have value of their own. AltStreet's AcreTrader review records Argyle Farm at 145.90 total acres and 142.8 tillable: its $892,500 price is $6,250 per tillable acre and about $6,117 per total acre.
- How can the acre basis make a farm look cheaper?
- By quoting price per total acre on a farm with many non-farmed acres. A 160-acre farm with 120 tillable acres sold for $1,440,000 is $9,000 per total acre but $12,000 per tillable acre; compared with a fully tillable farm at $11,000 an acre, the first looks cheaper when it is not.
- Where do tillable acre figures come from?
- Usually from USDA Farm Service Agency records of cropland acres, field maps, and the lease, which normally states the acres rented. Check that the offering, the lease and the soil rating all use the same tillable figure.
- Do non-tillable acres have value?
- Sometimes. A building site, timber, hunting rights, wind or solar lease income, or conservation program payments can add value; ditches, steep waterways and road rights of way usually add little. Value them separately rather than averaging them into the cropland price.
