Restoring Vitality to Waterlogged Soils: How Agroforestry Transforms Land Reclamation and Sustainability
摘要
Waterlogging affects woody plants distribution as it not only restricts the seed germination but reproductive and vegetative growth, are also influenced by this issue that results in mortality of plants. It disturbs the soil physicochemical attributes that ultimately reduces the growth, physiological and biochemical characteristics of various trees species. Studies were performed to evaluate the waterlogged condition and its impact in semi-arid region of District Faisalabad and Nankana Sahib with prime objective to examine the ameliorative effects of selective species on the physicochemical attributes of waterlogged soils. Field visits were carried out in three waterlogged sites: Satiana, Chak Jhumra and Sangla Hill of the selected Districts to collect soil sampling at two depths: 0–15 cm and 15–30 cm to determine the physicochemical properties of soil under and away the tree canopies. There was no remarkable change in soil pH at both depths however, a slightly higher pH was estimated under canopy soils as compared to away canopy soils. Higher soil organic matter (0.85%), soil nitrogen (0.051%), potassium (151 mg kg−1), phosphorous (6.84 mg kg−1) and saturation percentage (47.5%) was computed in under canopy soils for Chak Jhumra as compared to other study sites at 0–15 depth.
