Agricultural Land Assessment: What to Check Before Investing or Developing a Farm

Buying agricultural land or deciding to develop an existing property can involve a significant investment.

But a piece of land that looks green, fertile or productive is not necessarily suitable for the agricultural project being considered.

Good agricultural land is not simply land with good soil.

A successful farm depends on the combination of soil, water, climate, topography, access, infrastructure, crop suitability, market conditions and economics.

At The Green Van, agricultural development therefore starts by understanding the land before deciding what should be planted or built.

1. Start With the Site & Topography

The physical shape of the property affects almost every part of farm development.

An assessment should consider:

Slope • Elevation • Orientation • Terraces • Low points • Existing roads • Natural drainage • Usable agricultural area

A steep property may still have excellent agricultural potential, but development costs, machinery access and erosion management can be very different from a relatively flat site.

Topography also influences where infrastructure such as roads, reservoirs, greenhouses, buildings, irrigation networks and drainage systems should be positioned.

For larger developments, a proper topographic survey and agricultural base map can become one of the most important planning tools.

2. Understand the Soil

Soil should never be evaluated simply by looking at its color.

Different areas of the same property can have completely different characteristics.

Important factors can include:

Texture • pH • EC • Organic matter • Drainage • Compaction • Calcium carbonate • Nutrient status • Soil depth

A shallow rocky soil may be suitable for one crop but unsuitable for another.

Heavy clay may provide good nutrient and water-holding capacity but create serious drainage or aeration problems if poorly managed.

Likewise, high-pH or calcareous soils may require specific nutrient-management strategies and appropriate crop or rootstock selection.

Where significant investment is planned, soil samples should be taken from representative areas rather than relying on a single sample for the entire property.

3. Water Availability Can Determine the Entire Project

A property may have excellent soil and climate but still be unsuitable for intensive agriculture if sufficient irrigation water is unavailable.

Before development, determine:

Water source • Available quantity • Seasonal reliability • Storage capacity • Pumping requirements • Water quality

A well that provides adequate water in winter may not necessarily provide the same amount during peak summer demand.

The planned cultivated area should therefore reflect realistic water availability during the periods when crops require it most.

Water storage may also be necessary to balance supply and irrigation demand.

4. Test the Irrigation Water

Quantity alone is not enough.

Water quality can influence soil conditions, fertilizer management and crop selection.

Depending on the project, analysis may include:

pH • EC • Bicarbonates • Sodium • Chloride • Relevant mineral concentrations

Poor-quality irrigation water does not always make agriculture impossible.

But it can change the design of the project and may require filtration, treatment, blending or specific management practices.

Understanding this before planting is considerably easier than discovering it after thousands of trees have already been installed.

5. Study the Climate & Altitude

Climate determines which crops can realistically perform on the property.

Important considerations include:

Minimum winter temperatures • Maximum summer temperatures • Frost • Rainfall • Humidity • Wind • Snow • Growing-season length • Sun exposure

Altitude can dramatically change growing conditions over relatively short distances.

In mountainous regions, two farms located only a few kilometers apart can experience very different temperatures, frost dates and production seasons.

Microclimates within the property should also be considered.

Low areas may collect cold air, exposed ridges may experience stronger winds and different orientations can receive significantly different amounts of sunlight.

6. Check Drainage

Poor drainage is one of the most expensive agricultural problems to discover after development.

Look for:

Standing water • Water marks • Compacted layers • Poor infiltration • Low areas • Damaged trees • Surface runoff patterns

Drainage problems can affect root health, nutrient uptake, machinery access and disease pressure.

In some properties, drainage can be improved relatively easily.

In others, significant earthworks or drainage infrastructure may be required.

That cost needs to be understood before the investment decision is made.

7. Investigate Previous Land Use

What happened on the property before you arrived can matter.

Previous activities may include:

Agriculture • Grazing • Abandoned orchards • Intensive fertilizer use • Herbicide use • Construction • Waste dumping • Long periods without cultivation

Existing vegetation can also provide useful clues.

Poor-performing trees, persistent weeds, bare areas or uneven vegetation may indicate underlying differences in soil, drainage or previous management.

The objective is not to judge the previous owner.

It is to understand what conditions the new project is inheriting.

8. Evaluate Access & Machinery

A productive farm still needs to function operationally.

Ask:

Can trucks enter the property?

Can tractors reach the production areas?

Are roads wide enough?

Can machinery turn comfortably?

Can harvested crops be transported efficiently?

Poorly designed access can increase labor and machinery costs throughout the lifetime of the project.

For commercial agriculture, roads and machinery movement should therefore be considered during the initial design—not after planting.

9. Assess Existing Infrastructure

Existing infrastructure can significantly affect development costs.

This may include:

Wells • Reservoirs • Irrigation networks • Electricity • Solar systems • Roads • Buildings • Greenhouses • Fencing • Packing areas • Storage facilities

But existing infrastructure should not automatically be considered an advantage.

An irrigation system that is badly designed or a greenhouse positioned in the wrong location may require replacement or relocation.

The assessment should determine what can be retained, what should be improved and what should be replaced.

10. Select Crops After Assessing the Land

Crop selection should come after understanding the property.

The decision should consider:

Soil • Water • Climate • Altitude • Market • Labor • Investment • Production timeline • Expected returns

A crop that grows successfully in the region is not automatically the best crop for every property.

For perennial crops, variety and rootstock selection are especially important because the decision may remain in place for decades.

The objective should be to identify crops that are both agronomically suitable and commercially sensible.

11. Consider the Market

Agricultural feasibility does not stop at the farm gate.

Before developing commercial production, understand:

Who will buy the product?

At what price?

During which season?

What quality is required?

How much competition exists?

How will the product be packed and transported?

A crop can perform perfectly in the field and still make a poor investment if the market cannot absorb the production at a viable price.

This is why agricultural assessment and financial feasibility should ultimately connect.

12. Identify Red Flags Before Investing

Some problems do not necessarily prevent development, but they can significantly change its cost or risk.

Typical red flags may include:

Unreliable water supply

Poor drainage

Severe salinity

Very shallow soil

Extreme slopes

Strong wind exposure

Difficult machinery access

Unsuitable existing crops

Badly positioned infrastructure

High remediation requirements

Insufficient electricity for controlled systems

A crop plan that does not match the local market

Identifying these issues before development allows them to be priced, redesigned or avoided.

Discovering them afterwards can be considerably more expensive.

13. Look for Opportunities Too

An agricultural assessment should not only identify problems.

It should also reveal opportunities.

A property may have:

Unused water resources • Existing terraces • Valuable mature trees • Good greenhouse locations • Excellent sun exposure • Suitable areas for reservoirs • Potential for livestock • Eco-tourism opportunities • Renewable-energy potential

Different parts of the property may also be suited to completely different uses.

This is why larger farms are often better divided into zones and subzones, with each area assessed according to its specific characteristics.

14. Estimate the Real Development Cost

Once the land and production direction are understood, the next step is determining what development will actually require.

Potential investment may include:

Land preparation • Roads • Irrigation • Reservoirs • Drainage • Electricity • Solar power • Greenhouses • Trees • Plants • Machinery • Buildings • Fencing • Packing infrastructure

This allows the project to move from:

“What could we grow here?”

to:

“What should we develop here, what will it cost, and what can it realistically return?”

15. Develop in Phases When Appropriate

Not every property needs to be developed at once.

Large agricultural projects can often be divided into phases.

For example:

Phase 1 — Water, roads and infrastructure

Phase 2 — Initial production area

Phase 3 — Expansion

Phase 4 — Processing, livestock, tourism or other complementary activities

Phasing can reduce initial capital requirements and allow the farm to gain operational experience before expanding.

However, the complete property should ideally be planned from the beginning, so early infrastructure does not interfere with future development.

Assess Before You Invest

Many expensive agricultural mistakes happen because development begins too quickly.

Trees are planted before the soil is understood.

Greenhouses are built before water availability is confirmed.

Roads are constructed before the farm layout is designed.

Crops are selected before the market is studied.

A professional agricultural assessment provides the information needed to make these decisions in the correct order.

At The Green Van, our assessment process evaluates the land, soil, water, climate, infrastructure, existing agricultural systems, development constraints and potential opportunities before recommending how the property should move forward.

The objective is not simply to identify what can grow.

It is to determine how the land can be developed into a practical, productive and financially viable agricultural operation.

Frequently Asked Questions

Should I assess agricultural land before buying it?
For a significant agricultural investment, yes. An assessment can identify limitations related to soil, water, access, climate or infrastructure before the purchase decision is made.

Is good soil enough to make land suitable for farming?
No. Water availability, climate, drainage, access, infrastructure, crop suitability and market conditions can be equally important.

How many soil samples should be taken?
It depends on the size and variability of the property. Different soil types, terraces, elevations or visibly different areas may need to be sampled separately.

Should water be tested before selecting crops?
Yes. Both water quantity and quality can influence crop selection, irrigation design and long-term soil management.

Can difficult agricultural land still be developed?
Often, yes. The important question is whether the required corrections and infrastructure are technically and financially justified.
