The invention being presented here is for SUB SOIL DRIBBLERS which are manufactured from permeable materials duly pulverised and mixed, dried and kept in a plastic container for irrigation purposes. The composition of these blocks is determined in such a way that water can be fed to the plant under the soil, in a controlled and self regulated way and using gravity flow system. The water gets transmitted from the container- to the plant by these SSDs, which allow the collected water to seep though and trickle under the soil towards the plant. The SSDs work in Tandem with the auto regulated containers mounted on top of the SSDs. These containers gets automatically filled to a desired level by the help of float type level actuated valves. The water so collected in these containers of 1 ltr capacity is allowed to trickle towards the plant over a period of time, which can vary as per the plant needs.
