coated urea treatments did not reduce the CO 2 emissions. Higher N 2 O fluxes were observed
immediately after fertilizer application. Among natural nitrification inhibitors, vitex cake
coated urea recorded lower N 2 O fluxes and this was followed by neem cake coated urea.
Conclusion
In- situ moisture conservation practices and Coating of urea with natural nitrification
inhibitors were found quite effective for adaptation and mitigation of climate change in semiarid
rainfed regions.

A subsoiler is a tractor-mounted farm implement used for deep tillage, loosening and breaking
up of soil at depths twice the depth of the normal tillage implement i.e. depth more than 30cm.
As subsoiler loosens the deep compacted soil, it increases the infiltration rate thereby
conserving the soil moisture. Subsoiling will not overturn the top-soil but disturbs and breaks
the plough layer, which result in improving the permeability of soil water, creating a "water
reservoir" underneath the soil surface, increasing the efficiency of rainwater use, and improving
the ability of water conservation in arid areas. Subsequently, it also minimizes the effect of
