Soil Testing & Advisory
Understand Your Soil Before You Decide What It Needs
Test • Understand • Recommend • Improve • Monitor
Healthy agriculture begins below the ground.
Many crop problems are addressed only after visible symptoms appear. But poor crop growth, nutrient imbalance, weak root development and inefficient input use can often be connected with underlying soil conditions.
Sansar Green’s Soil Testing & Advisory approach is designed to help farmers move from guesswork toward informed soil and crop management.
Our approach is:
SOIL SAMPLE → TEST → INTERPRET → CROP CONTEXT → ADVISORY → ACTION → FOLLOW-UP
The objective is not simply to provide a laboratory report.
The objective is to help farmers understand what the report means for their farm.

Why Test Your Soil?
A soil may look healthy but still have limitations that cannot be identified visually.
Soil testing can help understand:
Soil Reaction
Salinity Conditions
Organic Carbon Status
Nutrient Availability
Potential Nutrient Imbalances
Crop-Specific Nutrient Requirements
Need for Soil Improvement
Changes in Soil Over Time
Testing provides information that can support better agricultural decisions.
Don’t Begin with the Product. Begin with the Soil.
Applying agricultural inputs without understanding the soil can lead to unnecessary cost, inappropriate application or poor response.
Our preferred sequence is:
UNDERSTAND THE SOIL
↓
UNDERSTAND THE CROP
↓
IDENTIFY THE NEED
↓
PLAN THE INTERVENTION
↓
MONITOR THE RESPONSE
This principle connects soil testing with Sansar Green’s wider crop-advisory and farmer-support ecosystem.
What Can Be Tested?
Depending on the testing package and laboratory capability, soil analysis may include parameters such as:
pH
Electrical Conductivity
Organic Carbon
Available Nitrogen
Available Phosphorus
Available Potassium
Sulphur
Selected Secondary Nutrients
Selected Micronutrients
Other relevant soil parameters
The exact parameters tested should always be clearly mentioned in the selected soil-testing package.
Understanding Soil pH
Soil pH influences:
Nutrient Availability
Microbial Activity
Root Environment
Crop Performance
A soil-test report helps determine whether the soil is acidic, near neutral or alkaline.
The interpretation should consider the crop and local soil conditions rather than treating one pH value as ideal for every crop.
Electrical Conductivity
Electrical Conductivity, or EC, provides information related to soluble salts in the soil.
High salt levels can affect:
Seed Germination
Root Development
Water Uptake
Plant Growth
Crop Performance
EC should be interpreted together with crop sensitivity, irrigation water and field conditions.
Soil Organic Carbon
Organic carbon is an important soil-health indicator.
It is associated with processes involving:
Organic Matter
Soil Structure
Biological Activity
Nutrient Cycling
Water Relations
Long-term soil management should consider organic carbon alongside other physical, chemical and biological characteristics.
Major Nutrients
Crop production depends on an appropriate supply of essential nutrients.
Soil testing can help evaluate nutrient status and support crop-specific nutrient planning.
Important nutrients commonly assessed include:
Nitrogen
Phosphorus
Potassium
Nutrient requirements differ according to crop, soil, growth stage, production target and management system.
Secondary & Micronutrients
Plants also require nutrients in smaller quantities.
Depending on the crop and testing requirement, assessment may include nutrients such as:
Sulphur
Zinc
Boron
Iron
Manganese
Copper
Other relevant nutrients
A micronutrient should not be applied simply because it is important to plants. The need should be assessed from soil, crop and other relevant information.
Soil Sampling Matters
A Good Report Begins with a Good Sample
Even a good laboratory cannot produce a representative field result from a poorly collected sample.
Correct sampling is therefore critical.
Farmers should consider:
Correct Sampling Area
Appropriate Sampling Depth
Multiple Sampling Points
Representative Mixing
Clean Collection Tools
Clean Sample Bag
Proper Identification
Avoiding Unusual Spots
Samples should generally not be taken from locations that do not represent the field, such as immediately beside manure heaps, bunds, water channels or isolated abnormal patches unless those areas are being investigated separately.
Sampling procedures may vary according to crop and purpose.
From Field to Soil Report
A structured soil-testing journey can follow:
FARMER REGISTRATION
↓
FARM / PLOT IDENTIFICATION

CROP-SPECIFIC ADVISORY
This creates greater continuity between testing and agricultural action.
Your Soil Report Should Be Easy to Understand
A farmer should not receive only a page of numbers.
A useful soil report can progressively explain:
Parameter Tested
Result
Unit
Interpretation
Soil Status
Agricultural Relevance
Crop Context
Suggested Management Direction
Follow-Up Requirement
Technical information should be translated into farmer-friendly agricultural knowledge.
Soil Testing + Crop Advisory
The same soil report may lead to different management decisions for different crops.
Therefore:

Soil Testing for Natural Farming
Farmers transitioning toward natural farming can use soil testing to establish a baseline.
Important areas can include:
pH
Organic Carbon
Nutrient Status
Organic Matter Management
Soil Biology
Root-Zone Conditions
Follow-Up Changes
The objective should be to measure changes rather than assume that a farming practice has improved the soil.
[Explore Natural Farming → /natural-farming/]
Soil Testing for Organic Farming
Soil information can also support organic-farming planning through better understanding of:
Soil Condition
Organic Matter
Nutrient Status
Crop Requirement
Long-Term Fertility Management
Soil testing is only one part of an organic production system and should be combined with appropriate farm records and applicable standards.
[Explore Organic Farming → /organic-farming/]
Soil Testing for Horticulture & Orchards
Perennial crops require long-term soil and root-zone management.
Soil testing can support planning for:
Mango
Fruit Crops
Orchards
Vegetables
Nurseries
Plantations
Grafted Plants
Before establishing a new orchard, understanding the soil can help inform decisions relating to crop suitability, root-zone preparation, organic matter, nutrition and water management.
Root-Zone Advisory
A laboratory soil test is important, but soil health is broader than laboratory chemistry.
Root-zone assessment may also consider:
Soil Structure
Compaction
Drainage
Moisture
Aeration
Organic Matter
Root Development
Biological Activity
A plant interacts with the entire root environment.
Soil Biology & Microorganisms
Soil is a living system.
Sansar Green’s wider research ecosystem also studies:
Agricultural Microbiology
Rhizosphere
Beneficial Microorganisms
Soil–Plant–Microbe Interactions
Microbial Strains
Biological Nutrient Cycling
[Explore Soil & Microbial Research → /soil-microbial-research/]
Bio-Input Advisory Based on Need
Soil testing can support more responsible decisions about biological and nutritional inputs.
The approach should be:
SOIL
↓
CROP
↓
IDENTIFIED NEED
↓
BIOLOGICAL / NUTRITIONAL FUNCTION
↓
SUITABLE SOLUTION
Not every soil requires the same intervention.

Soil Testing for FPOs & Farmer Groups
Farmer groups and FPOs can use organised soil-testing programmes to better understand agricultural conditions across larger production areas.
Potential programmes may include:
Village Soil Sampling
Farmer Registration
Plot Mapping
Soil Testing
Crop Planning
Farmer Training
Digital Reports
Group Advisory
