Soil conditioners as candidates to mitigate salt/water stress effects on sorghum growth and soil properties

Alum Sludge as a Soil Amendment: Effects on Soil Properties and Plant Growth

Effects of electric-arc furnace dust application on soil properties, sorghum growth, and heavy-metal accumulation

This study investigated the possibility of using electric-arc furnace dust (EAFD) as an acidic soil amendment. The experiments were conducted using incubation and pot experiments. In the incubation experiment, various rates of EAFD were added to an acidic soil and properties such as pH; electrical conductivity of the saturation extract (ECse); and available phosphorus (P), potassium (K), iron (...

Effects of ridge and conventional tillage systems on soil properties and cotton growth

Cotton (Gossypium hirsutum L.) seeds are susceptible to low temperature and excess moisture in soil during seed emergence in years with high rainfall and low temperature in spring. Therefore, a two-year field experiment was carried out to evaluate effects of ridge tillage formed in autumn (RT-I), ridge tillage formed about a month before planting (RT-II) and flat conventional tillage (CT) culti...

Stimulatory Effects of Arsenic-Tolerant Soil Fungi on Plant Growth Promotion and Soil Properties

Fifteen fungi were obtained from arsenic-contaminated agricultural fields in West Bengal, India and examined for their arsenic tolerance and removal ability in our previous study. Of these, the four best arsenic-remediating isolates were tested for plant growth promotion effects on rice and pea in the present study. A greenhouse-based pot experiment was conducted using soil inocula of individua...

Soil carbon sequestration to mitigate climate change

The increase in atmospheric concentration of CO2 by 31% since 1750 from fossil fuel combustion and land use change necessitates identification of strategies for mitigating the threat of the attendant global warming. Since the industrial revolution, global emissions of carbon (C) are estimated at 270F 30 Pg (Pg = petagram= 10 g = 1 billion ton) due to fossil fuel combustion and 136F 55 Pg due to...
