New Delhi (ABC Live) : NBSS BHOOMI Geo-portal : The National Bureau of Soil Survey and Land Use Planning (NBSS&LUP) developed NBSS BHOOMI Geo-portal to access various thematic information on major physiographic regions, sub-physiographic regions of India, agro-ecological regions (1992), agro-ecological regions (2015) and agro ecological sub-regions of the country.
Area/region specific efficient and remunerative crops and cropping sequences were delineated based on soils, landforms, rainfall, temperature, length of growing period and irritability.
The NBSS&LUP developed an android based mobile application on GIS platform to facilitate web-based decision support system (DSS) for land use planning and dissemination of soil health cards information at village and farm level for Gujarat. App will display details of soil map unit information and suggested land use plan for that survey number.
The NBSS&LUP has so far prepared Land Resource Inventory (LRI) of 99 blocks. These digitized maps of micronutrients status would be helpful in providing site-specific variable rate application of micronutrients prescription for sustainable agricultural productivity.
Application of Leucaena biochar, significantly reduced ammonium content of soil, whereas increased nitrate N. Check dams, constructed using two thickness of sheets for 1.2 m high head wall with MS angle frame, saved 30-47% on cost without any effect on life and performance of the check dam.
Such constructions will be very useful for installation of quick and low cost check dam structures in remote areas.
The subsurface drainage (SSD) system was installed in waterlogged saline soils at 2 locations of Bharuch district of Gujarat.
Local communities are being sensitized for the active participation for successful operation of these projects.
Determination of lead and cadmium concentration limits in agricultural soil and municipal solid waste compost through an approach of zero tolerance to food contamination was developed.
Bilingual (Marathi and English) STCR mobile App for fertilizer recommendations of Maharashtra, helps realize the targeted yield of crops.
Using National Aeronautics and Space Administration’s (NASA) Gravity Recovery and Climate Experiment (GRACE) data, groundwater storage changes in India were assessed, and the results were validated for the first time using in-situ observation.
The AICRP on Integrated Farming Systems (IFS) is operational in 24 states and 1 union territory covering all the 15 Agro-climatic regions of country. Region specific IFS models, developed in 14 agro-climatic regions along with business model (Bankable projects), indicated 2-3 times higher income than existing farming systems.
The model with field crops, horticultural crops, livestock, fishery, and other components like vermicompost, biogas unit and composting unit developed in lower Gangetic plains agro-climatic region in Kalyani, West Bengal, recorded higher sustainability yield index (SYI) of 0.78, followed by a model with cropping systems, dairy, horticulture, vermicompost and water harvest in SK Nagar, Gujarat with 0.66 SYI.
A negative correlation between SYI and coefficient of variation (CV) of annual rainfall, showed that inter-annual rainfall variation has visible impact on sustainability of integrated farming systems. Under Network Project on Organic Farming (NPOF), best performing varieties of crops for organic farming were identified in 16 states.
A database Management System was developed including district level data on land use classification (9 fold), source-wise net irrigated area, indicators of extent of irrigated area, fertilizer consumption (N, P and K), monthly rainfall and crop wise area sown, production and yield and area sown with irrigation (for 20 crops) etc.
The Decision Support System (DSS) was developed accommodating 15 rainfed crops, viz. rice, sorghum, pearl millet, maize, finger millet, chickpea, pigeon pea, black gram, green gram, groundnut, soybean, sunflower, sesame, castor and cotton.
Synthesised Nanoclay, developed using matured coconut water as capping material, will reduce the seepage from ponds, and can play very important role in using poor quality soil for aquaculture.
