Sustainable soil health or quality maintenance through balanced fertilization in combination of organic and inorganic sources along with addressing the complicated problems of soils of Tamil Nadu through basic and applied research forms the aim of this centre. Capacity of a soil to function within ecosystem boundaries to sustain biological productivity, maintain environmental quality and promote plant and animal health. In the context of agriculture, it may refer to its ability to sustain productivity.
A healthy soil would ensure proper retention and release of water and nutrients, promote and sustain root growth, maintain soil biotic habitat, respond to management and resist degradation. Sustainable soil health is governed by a number of physical, chemical and biological attributes
and processes, which are expressed by different quantitative and qualitative measures. These attributes governs the productivity, nutrient and water use efficiencies and quality of produce.
This could be achieved in another three years through following sustained effort of the Centre of Excellence which is established at Trichy with a financial support by the Government of Tamil Nadu to a tune of Rs. 470 lakhs.
and mapping of salt affected soils and ground water quality and to develop
suitable management strategies
for improving soil health and crop productivity through Integrated Plant Nutrient System.
Ø Identification and standardization of microbial consortia and biofertilizers suitable for problem soils and rainfed lands.
Ø To study impact of sewage and industrial wastes for exploring the possibility of eco-friendly management and wealth.
Ø To evaluate and demonstrate suitable Integrated Farming System model for sustaining soil health in salt affected soils.
Ø To train the scientists/ extension functionaries and farmers on areas of soil fertility management and soil health sustenance and on using decision support system tools viz., DSSIFER, VDK, NUTMON,etc.Project Strategy
This project is planned for establishing Centre of excellence on Soil Heath Management at ADAC & RI, Trichy as the lead centre for the management of problem soils and water through the development of suitable technologies involving multi disciplines such as Soil Science, Agronomy, Microbiology, Crop Physiology, Environmental Science, Remote Sensing and Soil and Water Conservation Engineering through holistic approach.
Ø Effective monitoring and co-ordination of all the Research and Development activities connected with soil health management studies of different research centres of TNAU through Centre of Excellence on sustainable Soil Health Management can be achieved
Ø Low cost, Eco friendly viable green technology through the use of improved and efficient biofertilizer inocula with assured quality and enhanced shelf life of Agro products can be achieved
Ø Reassessment and delineation of problem soils and water sources provides an insight on the severity of problem in the state and also gives vision for the policy planners for sustainable development.
Ø Site specific management technologies will be of highly useful to the end users to rejuvenate their problem soils and water bodies at safer level. Special package on coastal soil and water management technologies evolved will improve the standard of living in coastal regions
Ø Effective utilization of sewage and industrial wastes for maintenance of soil health without causing damage to environment.
Ø Suitable IFS model will be evaluated for different ecosystems for the benefit of small and marginal farmers.
Ø Economic upliftment and year round income generation of local people.
Ø Capacity building for the technical persons and educate farmers on soil testing, soil constraints and fertility and their management
