If I am in a place like a farm, etc. No water around and i have none, how can I perform wudhu for Salaat?

When no water is found within the radius of one mile, then a person should perform Tayammum and perform Salaat.

The method of Tayammum is firstly to make the intention of Tayammum, secondly, strike both hands on clean earth or dust. Then dust the hands and blow off the excess dust, thereafter rub both the hands over the complete face without leaving a hair?s breadth of space. Thirdly, strike both hands on the ground, blow off the excess dust and rub the left hand over the complete right hand, including the elbow.

and Allah Ta'ala Knows Best
