CA is based on three principles, applied simultaneously (FAO, 2009)
(the minimum soil
to sow the seed)
(retention of adequate
levels of crop residues
on the soil surface)
(to help moderate possible
weed, disease and pest
Important benefits of CA
Increased soil organic matter
Improved soil quality and sustain fertility
Increased availability of nutrients for plant (in long-run)
Retain soil moisture content and improves biological activities
Improved crop production
Reduced energy inputs
Enhanced ecosystem services
To evaluate the short to medium term impact of
conservation agriculture on soil health indicators.
To compare the soil nutrient availability in between
different CA practices after three years of experiment.
Cereal Systems Initiative for South
Asia (CSISA) - A research platform
placed in Haryana

Agro-Eco Lab, Jiwaji University, Gwalior, INDIA
A continuous Rice-Wheat cropping system
for many years before the establishment of
research platform (Nov, 2009) at Haryana,
India (29°70′N, 76°96′E).
• Objective 1
The soil samples (Initial baseline after uniformity of rice crop- November 2009
and after three years of long term experiment –October-November 2012) were
taken from the aforementioned trials and analysed for the following parameters
in IARI’s laboratory
1. pH (soil : water suspension 1:2) procedure given by Jackson (1973).
2. Electrical Conductivity (soil : water suspension 1:2) procedure given by
3. Soil Organic Carbon determined by Walkley and Black method (1934).
4. Available Nitrogen by method of Subbiah and Asija (1956).
5. Available Potassium by method of Hanway and Heidel, (1952).
Under process outcome …
● CA practices improves soil health and its quality in terms of
sustainability as compared to conventional Agriculture.
● It enhances soil organic carbon content, nitrogen and
potassium particularly more in R-W system
