The diversity of Patanas varies in habitat, their productivity may be closely linked to a variety of factors, and water, temperature, soil nutrient status and biological disturbances are considered as particularly important factors. It is already known that most of Sri Lanka’s soil has low potential and capacity for nutrition, even more so in Patna. In Patna
