Soil characteristics of post-mining reclamation land and natural soil without top soil

Biochar for soil remediation and land reclamation

Land reclamation generally relates to the improvement of soils degraded by human activities, for example construction and certain forms of agriculture. Soil remediation refers to the process of removing, neutralizing or reducing the toxicity of certain compounds, often left by human activities such as mining and industry. Each degraded and/or contaminated site is potentially unique in its chara...

Engineering Characteristics of Natural Soil Formation

Sodic soil reclamation: Modelling and field study

Reclamation of sodic soils has traditionally been undertaken using calculation of gypsum or Ca requirement assuming 100% exchange efficiency and neglect of the contribution of calcium carbonate in the profile. The UNSATCHEM model is reviewed and then evaluated for its ability to predict field reclamation of a sodic saline soil. The 40-ha field site was initially at an electrical conductivity (E...

Effects of Sandy Desertified Land Reclamation on Soil Carbon Sequestration (Key Study: Kerman province)

Desertification leads to decrease in the ecosystem C pool and attendant reduction in Soil Organic Carbon (SOC). Reclamation of sandy land in arid and semi-arid has a high potential to increase carbon sequestration and improving soil quality. Our objective as to examine the changes in the soil carbon sequestration and soil properties of two soil layers (0–20 and 20-50 cm) under two types of recl...

The Effect of Land use and Soil Erosion on Soil Organic Carbon and Nitrogen Stock

  Soil organic carbon (SOC) is a principal component in soil quality assessment. Knowledge of SOC and total nitrogen (TN) stocks are important keys to understand the role of SOC in the global carbon cycle and, as a result, in the mitigation of global greenhouse effects. SOC and TN stocks are functions of the SOC concentration and the bulk density of the soil that are prone to changes, influe...
