A field experiment was conducted on the selected lowlands of northern Tanzania using a randomised complete block design to study the effectiveness of supplying gypsum (CaSO4.2H2O) or farmyard manure (FMY) alone or both mixtures on the reclamation of a sodic soil. Sodic soil and FYM were ...
This inevitably means that the agricultural sector will increasingly be dealing with saline and saline- sodic soils. An increasingly popular approach to improve soil structure in these soils mostly in arid and semi-arid regions where soil organic matter is scarce is the incorporation of organic ...
These studies suggest that gypsum passed through a 2-mm sieve, having a wide particle size distribution, is likely to be more efficient for the reclamation of sodic soils with appreciable quantities of Na 2CO 3 in the soil solution. 展开 ...
Compared with conventional treatment, GF2 significantly reduced the ECe and SAR of the soil and improved physical properties such as ζ-potential, dispersible clay conten 展开 关键词: Saline sodic soil horizontal flushing gypsum rice wheat carbonate and bi-carbonate ...
Therefore, a laboratory experiment was conducted to investigate the impact of municipal solid waste compost (MSWC) in reclamation of saline-sodic soil with pH, electrical conductivity (EC) and exchangeable sodium per cent of 10.7, 3.09 dS m−1 and 70.3, respectively. Soil with gypsum (25 and...
To evaluate the influence of wetland reclamation on vertical distribution of carbon and nitrogen in coastal wetland soils, we measured the soil organic carbon (SOC), soil total nitrogen (STN) and selected soil properties at five sampling plots (reed mars
The effectiveness of sequential application of gypsum followed by matured mixed municipal solid waste (MSW) compost was investigated for the reclamation of saline-sodic soils. Soil plots were treated with 50 dt/ha (dry tone/hectare) of gypsum, followed by the addition of matured MSW compost at ...
Desulfurized gypsum (DG) is a by-product of thermal power plants. DG has a high content of pure gypsum (>900gkg1). DG was used as an external source of Ca2+ for reclamation of saline-sodic soil. DG improved physical and chemical properties of saline-sodic soil. DG also increased growt...

Methods to increase C stocks in these lands are discussed with a focus on biochar application as a potential new approach to not only to increase the C content but also to improve soil properties. Gaps in research knowledge in this field are then identified. ...
