Mineral Rights vs Surface Rights
Definition
Real estate can be divided into separate estates. The surface estate covers the land's surface: soil, crops, buildings and the right to farm. The mineral estate covers oil, gas, coal and other minerals beneath, and can be sold or reserved separately, creating a split estate. In many states the mineral owner has an implied right to use as much of the surface as reasonably necessary to reach the minerals, which can mean roads, well pads and pipelines on cropland, often with compensation set by agreement or state law. A farmland buyer who does not own the minerals buys a surface that someone else may have the right to use.
Why it matters
Farmland offerings price the surface; the mineral estate may belong to someone else. Where minerals are severed, a third party can have the right to build roads and well sites on cropland, and the investor's remedies may be limited to compensation under state law or a surface use agreement. Where the minerals are included, they can add income that a fractional investor should share in. Either way, the offering should say who owns the minerals and what any reservation allows.
Common misconceptions
- •Buying farmland does not automatically include the minerals beneath it.
- •A mineral reservation from decades ago still binds today's surface owner.
- •No current drilling does not mean no future risk. Rights can be leased and exercised later.
- •Mineral income is not always passed to fractional investors. Check the operating agreement.

Farmland Partners' disclosure (2025 Form 10-K)
Owns the surface rights to its farms; third parties may hold mineral and infrastructure access rights.
A seller of Colorado and Kansas farms retained 50% of the mineral rights.
No mineral development or significant power infrastructure on its farms other than where it owns the rights, at filing.
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
- Do farmland investors usually get the mineral rights?
- Not always. Farmland Partners says it owns the surface rights to its farms, but 'other persons or entities may own third-party access rights on our properties based upon their ownership of certain minerals.' On one acquisition of farms in Colorado and Kansas, 'the seller retained 50% of the mineral rights related to the farm.'
- Can a mineral owner drill on my farm?
- Often yes, within limits set by state law, the deed reservation and any surface use agreement. Farmland Partners warns it 'may be required to permit the owners of certain third-party access rights on our properties to enter and occupy parts of the properties,' which 'could materially and adversely impact the rental value.'
- Where does a split estate show up?
- In the chain of title: a deed that 'reserves' or 'excepts' minerals, or a separate mineral deed or lease. The title commitment usually lists mineral reservations as exceptions.
- Are mineral rights valuable on farmland?
- Sometimes, where there is production or leasing interest, through lease bonuses and royalties. Elsewhere they may have little value, but their separate ownership still affects who can use the surface.
