Scientific Soil Analysis, Nutrient Management & Sustainable Soil Health Solutions

Healthy Soil. Scientific Farming. Better Productivity. Sustainable Agriculture.

Introduction

Sansar Green Soil Testing Laboratory is a laboratory development and agricultural research initiative of Sansar Green Mission Private Limited, a DPIIT-recognised agritech startup established in 2020, dedicated to advancing soil science, soil fertility assessment, nutrient management and sustainable agricultural practices.

Soil is the foundation of agricultural productivity, food security and environmental sustainability. Understanding its physical, chemical and biological properties is essential for effective crop nutrition, improved soil management and long-term agricultural development.

At Sansar Green, we believe that agricultural decisions should be supported by scientific evidence rather than assumptions. Our soil testing and research initiative aims to help farmers, agricultural enterprises, researchers and institutions understand soil characteristics and adopt appropriate soil management practices.

Our vision is to develop a comprehensive soil analysis and advisory ecosystem that connects laboratory-based investigations, field observations, soil health research, biological solutions and practical agricultural recommendations.

Through the broader Sansar Green philosophy of “मिट्टी से मंडी तक” — Soil to Market, we aim to connect scientific soil assessment with agricultural productivity, farmer prosperity and environmental responsibility.

Why Soil Testing Matters

Soil characteristics vary significantly across agricultural regions, fields and cropping systems.

Two farms growing the same crop may have different nutrient requirements because of differences in soil type, organic matter, pH, previous fertiliser applications, irrigation water quality and crop management history.

Scientific soil testing can help identify these differences and support more informed agricultural decisions.

Benefits of Soil Testing

Identifies important soil fertility characteristics.
Helps detect nutrient deficiencies and imbalances.
Supports appropriate fertiliser and amendment planning.
Assists in evaluating soil acidity, alkalinity and salinity.
Provides information for crop-specific nutrient management.
Helps avoid unnecessary or excessive fertiliser application.
Supports long-term soil health monitoring.
Provides baseline data for agricultural research and field trials.
Helps guide soil improvement and rehabilitation programmes.
Supports sustainable agricultural planning.

Soil testing is an important decision-support tool, although laboratory results must be interpreted alongside crop requirements, field history, local conditions and suitable agronomic recommendations.

Soil Sampling & Sample Preparation

Accurate soil testing begins with representative sample collection.

Improper sampling can produce misleading results even when laboratory analysis is performed correctly.

Recommended Soil Sampling Process

Step 1: Identify the Sampling Area

Divide fields into relatively uniform sections based on soil characteristics, crop history, management practices and visible differences.

Step 2: Collect Representative Subsamples

Collect multiple subsamples from the relevant area using clean sampling tools. Sampling depth should be appropriate for the crop and purpose of testing.

Step 3: Avoid Unrepresentative Locations

Avoid unusual spots such as fertiliser heaps, drainage channels, compost piles and recently amended patches unless these are the specific subject of investigation.

Step 4: Prepare a Composite Sample

Combine suitable subsamples thoroughly and retain the required quantity for analysis.

Step 5: Label the Sample

Record the farmer’s details, field identification, location, sampling date, crop history and relevant management information.

Step 6: Submit for Laboratory Analysis

Samples should be packed, stored and transported according to the requirements of the intended tests. Biological analyses may require different handling from routine chemical soil tests.
