1 Bhuvan based Soil Health Card and Mobile Application Dr. K. Sreenivas Head Soil & Land Resources Assessment division LRUMG, RSAA

2 Implementation Sampling - Grid of 2.5 ha in irrigated and 10 ha in rain fed areas - Cadastral maps to set the sample area Cadastral boundary (pink) Survey number 2.5 ha grid (Orange) Sample point Unguturu village (Irrigated area) - Guntur district: Area = 1033 ha, 147 grids (10ha)

3 SHC Application Homepage Major Functionalities User Registration and Authorization Soil Sample Registration Test Results Entry Geospatial Data visualization SHC Recommendations SHC Search and Print SHC Search and Bulk Print

4 User Authorization State wise Admin users for Authorization Option for Approve, Reject, Delete List for viewing Pending Requests Approved users Rejected users Role based access Data Provider Soil Sample Registration SHC Search and Print SHC Search and Bulk Print Analyst Test Result Entry Recommendations Supervisor Soil Sample Registration SHC Search and Print SHC Search and Bulk Print Test Result Entry Recommendations

5 Soil Sample Registration Registration of Soil Samples New Samples entry Editing Registered Samples 6 Crops 20 Farmers Adding new villages Validations - textual and numeric fields

6 Test Result Entry Search by Administrative Units State, District, Village Date Filters Option to Add Results New Samples Saved Samples Search by Soil Sample Number Option to enter Buffer ph and Titre values to compute lime and Gypsum requirement Validation of entries for better data entry

7 Option to Edit NPK values SHC Recommendations Complex and Straight Fertilizers Recommendation of Straight Fertilizers under Fertilizer Combination 1 Recommendation of Complex Fertilizers under Fertilizer Combination 2

8 Cost effective recommendation based on availability of fertilizers

9 SHC Search and Print 1. Moderated SHC for Print 6. Search by Soil Sample Number 2. Search by Administrative Units 7. Soil Health Card in PDF format 3. State, District, Village 8. Bulk Printing Option in PDF format 4. SHC for Six States (ANDHRA, TELANGANA, HARYANA, BENGAL, ASSAM & TAMIL NADU) 5. Date Filters

10 Soil Health Card Generation 1. Multilingual Support (Bengali, Hindi, Tamil, Telugu) 2. Crop wise Micronutrient Details 3. Support for QR Code for mobile integration for new Crop Recommendations 4. Handling fym, bio fertilizers, fertilizer combinations (straight, complex), micro and macro nutrients and units all in localized languages

21 SPATIAL MODELLING: RANDOM FORESTS Importance of variables to model Soil carbon densities

22 SOIL ORGANIC CARBON DENSITY SOIL INORGANIC CARBON DENSITY Soil carbon density in Kg m -2 Soil Organic Carbon stock 22.7 Pg Soil Inorganic Carbon stock Pg

23 TOTAL SOIL CARBON DENSITY Information on Soil Carbon density will be useful in prioritizing areas for soil carbon sequestration in different agro-climatic regions as well as for effective soil carbon management to reduceco2 emissions from soils.

24 SOIL HEALTH CARD... A GEO-SPATIAL SOLUTION Homogeneous Zones & Sampling locations Satellite data & derivatives Soil Sampling & analysis / Existing soil data VALIDATION DATA TRAINING DATA DEM VALIDATED OUTPUT NDVI Cadastre overlay & cadastre-wise soil health information Geology, etc... Land cover ph= 7.2, EC=1.2, OC= LOW... Bhuvan Location based info for Smart phones / SMS based for normal mobiles Soil property prediction using digital mapping techniques STCR equations / Decision rules

25 MANDAL : ONLY ACHAMPET, MAHABUBNAGAR DT. SMS Number: MICRO-NUTRIENT INFORMATION BY SMS Message should be given in the following format specified: 3 Keywords NRSC NDEM BHUVAN should be followed by Parcel Number, Village, Mandal e.g.: NRSC NDEM BHUVAN 114,achampet,achampet 1. First 3 keywords should be Capitals (NRSC NDEM BHUVAN), these 3 keywords should be separated by space 2. After the NRSC NDEM BHUVAN followed with space Parcel Number, Village, Mandal should be given separated by comma (114,achampet,achampet) If no matching results are found for the Parcel NO-DATA-AVAILABLE message will be obtained.
