A comparative evaluation of soil pH of different land use classes from district Gilgit, Pakistan

Abstract

Soil pH is an important factor for desirable crop productions. However, due to soil amendments it is changing and negatively impacting on agricultural produce and production. A total of 162 samples tested from three different land use classes (agriculture, barren and commercial) collected from four valleys of district Gilgit in Gilgit-Baltistan province of Pakistan. Different valleys and land use classes surveyed revealed a differential scope of pH level. However, in general entire soils are alkaline and pH ranges from 8.35 – 9.03 (average 8.65). Similarly, agriculture and barren lands in Gilgit town, Danyor and Sultanabad show relatively close affinity (average 8.52 and 8.62 respectively) as compared to Oshikhandas (average 9.02 and 9.03). Continuous unplanned use of chemical fertilizers and commercial wastes are continuously influence soil pH in the area which need a regular follow-up by the Government agriculture department. At the moments, farmers are totally ignorant about soil health status and such a technique or facility to monitor these parameters to optimize their agricultural productivity. Present study provides a baseline for future studies and caution for relevant departments to look into issues related to soil health. Study is unique and conducted for the first time from the area.
