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 30 different Villages of Mihterlam province capital of Laghman. Different vallages and land use classes surveyed revealed a differential scope of pH level. However, in general entire soils are alkaline and pH ranges from 6.87 – 8.95 (average 7.4).

A soil survey was conducted in the month of August, 2020 to assess soil pH, Composite surface soil samples were collected using stratified random sampling method at a depth of 0-15 cm from Agriculture, cultivated lands.

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.
