Quick Answer: How Do You Test Soil Before Planting?
How to Test Your Soil Before Planting: Soil pH Test Kits & Soil Testers for Nigerian Farmers. Before planting, collect representative soil samples from different parts of your farm and test important properties such as soil pH, nutrient status, organic matter and, where appropriate, moisture.
For quick on-farm checks, farmers can use a portable soil pH tester, digital soil pH meter or 3-in-1 soil pH and moisture meter.
For important fertilizer, liming or commercial production decisions, however, laboratory soil analysis provides much more information than a handheld meter.
Nigeria’s Nigerian Farmers Soil Health Scheme specifically promotes soil testing and crop- and location-specific fertilizer recommendations to help farmers make more informed soil-management decisions.

Why Should You Test Your Soil Before Planting?
Many farmers spend money on seeds, seedlings, fertilizers, herbicides, irrigation and labour before finding out whether their soil is suitable for the crop they intend to grow.
That can be an expensive mistake.
Two farms located in the same community can have different soil conditions because of their cropping history, fertilizer use, erosion, drainage, organic matter, previous liming and other management practices.
A soil test can help answer important questions such as:
- Is my soil too acidic or too alkaline?
- Does this crop require a different pH range?
- Should I apply lime?
- Does my soil need additional phosphorus or potassium?
- Am I already applying more fertilizer than necessary?
- Is poor crop performance actually related to soil fertility?
- Should I amend the soil before transplanting?
- Are there areas of the farm that should be managed differently?
Soil testing is widely used to assess soil fertility and determine appropriate fertilizer and lime requirements.
Instead of simply asking:
“Which fertilizer should I buy?”
A better question is:
“What does my soil need for the crop I want to plant?”
That difference can save money and improve the quality of your farm-management decisions.
What Is Soil pH?
Soil pH measures how acidic or alkaline your soil is.
The pH scale runs from 0 to 14:
- Below pH 7: acidic
- pH 7: neutral
- Above pH 7: alkaline
Soil pH matters because it affects nutrient availability, root development and several biological and chemical processes in the soil.
For many agricultural crops, a soil pH around 6.0–7.0 is generally favourable, although the ideal range varies by crop.
This is an important point.
There is no single perfect pH for every crop.
The correct soil pH for maize may not be exactly the same as the optimum range for another crop.
Therefore, test your soil and consider the crop you intend to grow before making amendments.
Why Soil pH Matters to Nigerian Farmers
You can apply quality seed and fertilizer and still experience disappointing growth when soil conditions are unsuitable.
Soil pH influences the availability of several plant nutrients. Very acidic or alkaline conditions can make certain nutrients less available even when those nutrients are present in the soil.
This means visible nutrient-deficiency symptoms do not automatically mean you should apply more fertilizer.
Sometimes the bigger problem may be:
- unsuitable soil pH;
- poor drainage;
- nutrient imbalance;
- low organic matter;
- compaction;
- inappropriate fertilizer selection;
- inadequate or excessive moisture.
Testing gives you more information before you spend money trying to correct the problem.
Soil pH Tester vs Laboratory Soil Test: What’s the Difference?
This distinction is extremely important.
Portable Soil pH Tester
A portable soil tester can provide a quick estimate of conditions in different parts of your farm.
Depending on the model, it may measure:
- pH;
- soil moisture;
- temperature;
- light intensity;
- electrical conductivity;
- or other parameters.
It is useful for:
- routine farm monitoring;
- checking multiple locations;
- vegetable gardens;
- nurseries;
- greenhouse production;
- field scouting;
- comparing different plots;
- checking moisture before irrigation.
Laboratory Soil Test
A proper laboratory soil test can provide much more detailed information.
Depending on the testing programme, results may include:
- soil pH;
- phosphorus;
- potassium;
- calcium;
- magnesium;
- micronutrients;
- organic matter;
- exchangeable acidity;
- other soil characteristics;
- fertilizer recommendations.
Nigeria’s Farmers Soil Health Scheme says its Soil Health Cards are designed to provide farmers with soil-status information and fertilizer/nutrient recommendations, including information on pH, macro- and micronutrients and organic content.
Which should you choose?
Ideally, use both for different purposes.
Use a portable tester for quick field monitoring.
Use laboratory testing when making significant fertilizer, liming or long-term soil-management decisions.
How to Test Your Soil Before Planting
Testing starts before you insert a probe into the ground.
You first need a representative sample or representative testing locations.
Step 1: Divide Your Farm Into Similar Areas
Do not automatically treat a large farm as one uniform piece of land.
Separate areas that are obviously different because of:
- slope;
- soil colour;
- drainage;
- previous crops;
- fertilizer history;
- manure application;
- irrigation;
- poor-performing sections;
- different soil textures.
Test these areas separately when appropriate.
Step 2: Select Several Testing Points
One reading from one corner of a farm does not necessarily represent the entire field.
When collecting samples for laboratory analysis, multiple smaller samples are normally collected to create a representative composite sample.
Research-based soil-sampling guidance emphasizes collecting multiple samples across the field rather than relying on one location.
Avoid unusual areas unless you specifically want to diagnose them, including:
- directly beside manure piles;
- fertilizer spill areas;
- drainage channels;
- animal congregation areas;
- fence lines;
- compost heaps;
- recently fertilized spots.
Step 3: Remove Surface Debris
Remove:
- weeds;
- dry leaves;
- stones;
- mulch;
- crop residue sitting on the surface.
You want to measure the soil, not surface material.
Step 4: Follow the Tester Manufacturer’s Instructions
Portable soil testers are not all used in exactly the same way.
Some probes can be inserted directly into appropriately moist soil.
Other digital meters may require:
- preparation of a soil-water mixture;
- calibration;
- cleaning between readings;
- buffer solutions.
Always follow the manufacturer’s instructions for the device you purchase.
Step 5: Take Multiple Readings
Do not rely on a single reading.
Take measurements in different parts of your field and record them.
For example:
| Farm Section | pH Reading | Moisture | Notes |
|---|---|---|---|
| Plot A | 5.5 | Medium | Maize planned |
| Plot B | 6.1 | Medium | Vegetables planned |
| Plot C | 5.2 | High | Poor drainage observed |
| Plot D | 6.4 | Low | Irrigation required |
Patterns are often more useful than one isolated number.
Step 6: Compare the Result With Your Crop Requirement
Once you know the approximate pH, check the recommended pH range for your intended crop.
Do not immediately apply lime, fertilizer or another amendment simply because you received a particular number.
For commercial farms, obtain proper soil-analysis recommendations where possible.
How to Collect Soil for Laboratory Testing
If you want a more detailed soil analysis, good sampling is critical.
A laboratory can only analyse the soil you send.
If your sample does not represent your field, even an accurate laboratory test can lead to poor decisions.
General soil-sampling process
- Divide the farm into reasonably uniform sections.
- Take multiple samples from each section.
- Use clean sampling equipment.
- Maintain a consistent sampling depth appropriate for your crop and test.
- Combine the subsamples when a composite sample is required.
- Mix thoroughly in a clean container.
- Submit the required quantity to the laboratory.
- Label every sample clearly.
- State the crop you intend to grow.
- Keep records of the results.
Avoid sampling immediately after fertilizer, lime or manure application because this can make the sample less representative.

Depending on the model, these may include:
- pH;
- moisture;
- temperature;
- fertility indicators;
- light;
- electrical conductivity.
These tools may be useful for farmers who want more information while scouting fields.
However, remember that a multifunction handheld instrument still does not automatically provide the same analysis as an agricultural soil laboratory.
5. Portable Soil Testing Kit for Farmers in Nigeria
A portable soil testing kit for farmers in Nigeria is useful where mobility is important.
For example, an agronomist, farm manager, extension worker or commercial farmer may want to test several plots in one day.
Look for a tool that is:
- lightweight;
- easy to clean;
- quick to operate;
- durable;
- understandable without complicated setup;
- suitable for field use;
- supported with clear instructions.
Soil pH Tester Price in Nigeria: What Determines the Cost?
One of the most common commercial searches is soil pH tester price in Nigeria.
There is no single price for every soil tester.
Prices depend on:
- brand;
- analogue vs digital design;
- number of functions;
- probe technology;
- measuring accuracy;
- build quality;
- display;
- calibration system;
- accessories;
- imported cost;
- exchange-rate changes;

A basic 3-in-1 tester will normally be priced differently from a more advanced digital multifunction tester.
Current Nigerian online-market listings show substantial price differences among 3-in-1, 4-in-1 and 6-in-1 soil-testing devices, confirming that functionality and product type significantly affect the selling price.
Before comparing only by price, ask:
What exactly does this tester measure?
A cheaper tester that only measures one variable should not be compared directly with a device that measures several parameters.
👉 [See Current Soil pH Tester Prices on FarmPays]
Soil Test Kit Price in Nigeria
The soil test kit price in Nigeria also depends on what is included in the kit.
Before buying, check whether you are purchasing:
- a simple probe;
- a 3-in-1 meter;
- a digital pH meter;
- a multifunction soil tester;
- a chemical test kit;
- or a laboratory sampling kit.
Read the product description carefully.
Do not assume every product called a “soil testing kit” measures nutrients such as nitrogen, phosphorus and potassium.
3 in 1 Soil pH Moisture Meter Price in Nigeria
Farmers searching for the 3 in 1 soil pH moisture meter price in Nigeria are often looking for an affordable tool that provides more than a basic pH reading.
These testers commonly combine several useful farm measurements in one device.
When comparing options, consider:
Probe quality
The probe is the part that interacts with the soil. Poor handling can damage some probes.
Reading scale
Choose a meter with an easy-to-understand display.
Intended use
A small garden meter and a professional field instrument may serve very different purposes.
Maintenance
Check whether the probe needs frequent calibration, batteries or special storage.
Seller support
Buying from an agricultural supplier can make it easier to understand whether the product is suitable for farm use.
Best Soil pH Tester for Farmers in Nigeria: What Should You Look For?
The best soil pH tester for farmers in Nigeria is not necessarily the most expensive one.
It is the device that matches your farming operation.
For a vegetable farmer
Consider:
- pH measurement;
- moisture monitoring;
- easy portability;
- repeated measurements.
For a greenhouse farmer
Consider:
- digital display;
- moisture measurement;
- temperature monitoring;
- accuracy and repeatability.
For a nursery
A portable pH and moisture meter may be convenient for checking different growing areas.
For a commercial crop farm
A field tester can be useful for monitoring, but combine it with laboratory soil analysis when making nutrient-management decisions.
For an agronomist or farm consultant
Consider a durable digital instrument capable of repeated field measurements and proper calibration.
Best Soil Testing Kit for Agriculture in Nigeria
Before choosing the best soil testing kit for agriculture in Nigeria, ask these seven questions:
- What parameters does it measure?
- How accurate is it according to the manufacturer?
- Does it require calibration?
- Is it suitable for direct soil measurement?
- How should the probe be cleaned?
- Are replacement parts available?
- Will I still need laboratory testing for my fertilizer programme?
These questions are more valuable than choosing a product purely because the packaging says “professional.”
How to Use a Soil pH and Moisture Tester for Farming
Exact instructions vary by model, so always use the manufacturer’s manual.
For common probe-based devices, the process may involve:
Step 1: Select the testing location
Choose representative parts of the field.
Step 2: Prepare the area
Remove stones and surface residue.
Step 3: Ensure suitable soil contact
Very dry or extremely hard soil may prevent proper probe contact and could potentially damage the device.
Step 4: Insert the probe as instructed
Never force a delicate probe through stones or very compacted ground.
Step 5: Allow the reading to stabilise
Follow your device instructions.
Step 6: Record the result
Keep records by field or plot.
Step 7: Repeat in several locations
Compare results instead of relying on one reading.
Step 8: Clean the probe
Clean according to manufacturer instructions before storage or moving to another sample.
Common Soil Testing Mistakes Farmers Should Avoid
Mistake 1: Testing only one part of the farm
One reading may not represent the entire field.
Mistake 2: Testing immediately beside fertilizer
You may get a misleading result.
Mistake 3: Assuming low pH automatically means “apply plenty of lime”
A soil test and crop requirement should guide amendment decisions.
Mistake 4: Assuming more fertilizer always means more yield
Over-application wastes money and may create nutrient and environmental problems. Soil-test recommendations can help farmers apply nutrients more strategically.
Mistake 5: Buying a soil tester without checking what it measures
A moisture meter is not necessarily a complete soil fertility tester.
Mistake 6: Ignoring calibration instructions
Digital meters that require calibration should be maintained according to the manufacturer’s instructions.
Mistake 7: Treating a handheld meter like a laboratory
A portable tester is valuable, but it cannot necessarily measure everything needed for a complete fertilizer recommendation.
What Should You Do After Testing Your Soil?
The purpose of soil testing is not simply to get a number.
The purpose is to make a better farming decision.
Depending on your result and professional recommendations, the next step may involve:
- choosing an appropriate fertilizer;
- correcting soil acidity;
- increasing organic matter;
- improving drainage;
- improving irrigation management;
- selecting suitable crops;
- adjusting fertilizer quantity;
- correcting specific nutrient deficiencies.
This is where soil testing can save money.
Instead of applying farm inputs blindly, you can buy products that address an identified need.
Soil Testing Before Buying Fertilizer
Suppose two farmers both intend to plant maize.
Farmer A buys fertilizer first and applies the same quantity used by another farmer.
Farmer B tests the soil, identifies the farm’s conditions and develops a nutrient plan based on the crop and soil results.
The second approach provides more information for making a fertilizer decision.
A proper soil test can help determine fertilizer and lime requirements rather than relying exclusively on guesswork.
Before buying fertilizer, ask:
- What crop am I planting?
- What is my soil pH?
- What nutrients are deficient?
- What nutrients are already adequate?
- What fertilizer formulation matches the recommendation?
- How much should I apply?
- When should I apply it?

What Soil pH Is Best for Crops?
There is no universal number for every crop.
Many agricultural crops perform well in the broadly slightly acidic to neutral range around pH 6–7, but individual crops have different preferences.
That means you should research the specific crop you intend to plant.
For example, the target pH for:
- maize;
- tomato;
- pepper;
- cucumber;
- watermelon;
- cocoa;
- plantain;
- cassava;
should be considered individually rather than assuming every crop has exactly the same requirement.
This also creates an important rule:
Test the soil with the intended crop in mind.
Can Soil pH Affect Fertilizer Performance?
Yes.
Soil pH influences nutrient availability.
For example, when pH is outside a crop’s favourable range, some nutrients may become less available to plants even if they are physically present in the soil.
This is one reason a farmer may see nutrient-deficiency symptoms despite applying fertilizer.
Do not automatically respond by applying more fertilizer.
First investigate the cause.
Portable Soil Tester or Laboratory Test: Which Is Better?
Neither completely replaces the other because they serve different purposes.
| Feature | Portable Soil Tester | Laboratory Soil Test |
|---|---|---|
| Fast field reading | Excellent | No |
| Easy to carry | Yes | Sample must be submitted |
| pH screening | Yes, depending on model | Yes |
| Moisture monitoring | Some models | Depends on test |
| Full nutrient analysis | Usually no | Yes, depending on lab package |
| Fertilizer recommendation | Not by itself | Often possible |
| Repeated field monitoring | Convenient | Less convenient |
| Commercial nutrient planning | Supplementary | Stronger option |
Best approach: use portable tools for monitoring and laboratory analysis for more complete fertility planning.
Why Soil Testing Is Becoming More Important in Nigeria
Soil testing is receiving increasing institutional attention in Nigeria.
The Federal Ministry of Agriculture and Food Security’s Nigerian Farmers Soil Health Scheme aims to promote location- and crop-specific soil-health management and more judicious fertilizer use.
The programme includes soil testing, Soil Health Cards and efforts to expand access to soil-information services.
For Nigerian farmers, the message is simple:
Know more about your soil before spending money trying to improve it.
