The potential for carbon bio-sequestration in China's paddy rice (Oryza sativa L.) as impacted by slag-based silicate fertilizer.
Rice is a typical silicon-accumulating plant. Silicon (Si), deposited as phytoliths during plant growth, has been shown to occlude organic carbon, which may prove to have significant effects on the biogeochemical sequestration of atmospheric CO2. This study evaluated the effects of silicate fertilization on plant Si uptake and carbon bio-sequestration in field trials on China's paddy soils. The...
متن کاملEffects of Slag-Based Silicon Fertilizer on Rice Growth and Brown-Spot Resistance
It is well documented that slag-based silicon fertilizers have beneficial effects on the growth and disease resistance of rice. However, their effects vary greatly with sources of slag and are closely related to availability of silicon (Si) in these materials. To date, few researches have been done to compare the differences in plant performance and disease resistance between different slag-bas...
متن کاملImpacts of Steel-Slag-Based Silicate Fertilizer on Soil Acidity and Silicon Availability and Metals-Immobilization in a Paddy Soil
Slag-based silicate fertilizer has been widely used to improve soil silicon- availability and crop productivity. A consecutive early rice-late rice rotation experiment was conducted to test the impacts of steel slag on soil pH, silicon availability, rice growth and metals-immobilization in paddy soil. Our results show that application of slag at a rate above higher or equal to 1 600 mg plant-av...
متن کاملAlum-Treated Poultry Litter as a Fertilizer Source
Alum used for poultry houses is sold under the commercial name of “Al+ Clear” in either liquid or dry form. Alum should not be confused with other litter treatment chemicals such as “PLT” (poultry litter treatment), as PLT is comprised mainly of sodium bisulfate (NaHSO4). Although PLT is effective at reducing ammonia levels, pathogens in house, energy costs, and potentially increasing forage yi...
متن کاملNitrogen Response Index as a Guide to Fertilizer Management
The efficiency with which fertilizer-nitrogen (N) is transferred to grain-N in cereals is usually less than 50% and averages 33% worldwide. Two long-term N fertility experiments were evaluated to examine temporal changes in nitrogen use efficiency (NUE) and their causes. Averaged over 30-yr, non-irrigated winter wheat NUE was 49% at a 22.4 kg N ha 1 yr 1 rate and decreased to 34% at a rate of 1...
