 Promoting optimum usage: The Raingun Irrigation System at a model farm at Anbil Dharmalingam Agricultural College and Research Institute in Tiruchi.
TIRUCHI: A model farm of Pressurised Irrigation Systems, featuring  models of different drip and sprinkler irrigation systems, has been set  up at the Tamil Nadu Agricultural University’s Anbil Dharmalingam  Agricultural College and Research Institute at Navalurkuttapattu near  Tiruchi. 
The farm has been set up to demonstrate water saving technologies for  sustainable agriculture and promote awareness among farmers. The farm features an advanced head control unit through which water soluble fertilizers can be mixed with irrigation water and applied directly to the crop. The head control is equipped with valves, filters and fertigation devices.
All types of sprinkler irrigation systems such as impact sprinkler,  raingun sprinkler, micro sprinkler and micro-jet spitters with wetting  diameters ranging from three to 60 metres have been designed, according  to S. Somasundaram, Assistant Professor (agronomy) of the college, who  designed the model farm. 
The systems have been demonstrated in a model farm in an area of  about 1.25 acres, where various crops have been raised, in the college  campus.Source--The Hindu
