Abstract:

Land-use management practices meritoriously influences on the soil quality and soil fertility status of the arid and semi-arid regions. Hence, this current research was organized in order to evaluate the impact of different land uses on the soil fertility status of dry semi-arid region Uthal, Pakistan. Treatments were comprised of five land uses (forestland, agro-horticulture land, wheat crop land, grassland, and barren land) and three soil depths 0-15, 15-30 and 30-45 cm with three replications. The outcomes indicated that forest land had the highest soil organic matter (1.20%), total organic carbon (12.02 mg/kg), available boron (8.20 mg/kg), sodium (27.58 meq/L), calcium (67.91 meq/L), magnesium (36.54 meq/L), available nitrogen (0.95 g/kg), available phosphorus (21.7 mg/kg) and available potassium (185 mg/kg) and the lowest were recorded in barren land under the depth of 0-15 cm. However, the highest pH (7.99), bulk density (1.58 g/cm3) were found in wheat cropland and the maximum electrical conductivity (1.08 dS/m) was found in barren land under the depth of 0-15 cm. The macroaggergates (97.16%) were found in grassland and lowest were reported in barren land (79.71%) at 0-15 cm depth. Microaggregates (26.44%) were found in barren land and lowest in grassland (2.87%) at the depth of 30-45 cm. In general, the larger size aggregates were found in grass land (56.75%) and the smallest aggregates were recorded on agro-horticulture land (9.30%). Macroaggregate had positive correlations with soil organic matter and other soil fertility characteristics. This research study determined that diverse land uses strongly affected the soil fertility status, highest was observed in forestland followed by grassland as compared to barren land in semi-arid region of Lasbela district. Hence cultivation practices could be implemented on barren land in order to preserve soil fertility status of semi-arid areas.
