The purpose of this research was to analyze soil samples from different altitudes of Nepal to know about their physical, chemical and biological properties; including the content of N, P, K, O, C, pH and population of bacteria, fungus and Azotobacter.
Materials and Methods
Soil sample assessment on "Altitudinal Variation in Soil MicrobialPopulation and Associated Soil Properties in Long Term Soil Fertility Trial" was carried out on 3 different altitudes; Terai (Agriculture Research Station, Parwanipur, Bara), Mid-hills (Regional Agriculture Research Station, Pakhribas, Dhankuta) and High-hills (Agriculture Research Station, Bijaynagar Jumla). There were 7 treatments in Jumla, 7 treatments in Pakhribas and 12 treatments in Parwanipur which were replicated thrice. Soil samples were taken after harvesting rice and the soil was subjected to determination of microbial population such as (Azotobacter, fungus and bacteria) along with soil chemical properties.
