Rice Husk Biochar

Biochar was produced from rice husk at temperature from 276 to 760 oC. The objective of the study was to determine the influence of the biochar application to loamy sand soil on crop growth and nutrient balances under greenhouse conditions in Hue city. Loamy sand soil was collected in Huong Chu commune, Huong Tra town. Pot experiments with Brassica juncea (Brassica juncea (L.) Czern.) were conducted in three different types of biochar quantity into soil such as 15 g/pot (765 g/m2), 30 g/pot (1531 g/m2) and 60 g/pot (3062 g/m2). Chemical fertilizer was applied to the soil at rates of 12.2÷ 24.5 g N/m2, 10.3÷ 20.6 g P2O5/m2 and 12.0 ÷ 24.0 g K2O/m2. Experimental results showed that biochar application changed soil quality, resulted in improving the growth of Brassica juncea. We will report the difference of nitrogen and phosphorus balances (crop uptake, leaching, retention, etc.) in experimental pots. Our results indicated that the use of biochar from agricultural by-products would be beneficial for farmers, the environment under soil and climatic conditions in Thua Thien Hue province.

Applications of large amounts of biosolid to agricultural lands have raised the concern over its potential impact on co-transport of metal contaminants. In this study, bulk biosolid was fractioned into six macro- and nano-biosolid fraction sizes. We investigated variations in the physicochemical properties of the different biosolid fraction sizes, and assessed sorption affinity and transport of Pb in a loamy sand soil. Decreasing biosolid fraction size from macro to nano resulted in consistent increases in surface area, surface charge, and a decrease in pore size. Biosolid particles >1000 µm showed similar surface properties that differ from biosolid particles < 1000 µm. Sorption affinity for Pb was larger on nano-biosolid as compared to all macro-biosolid fraction sizes. This is mainly attributed to the larger surface area and zeta potential of nano-biosolid, leading to increased surface reactivity and greater stability. Total amount eluted of Pb was increased in the presence of macro- and nano-biosolid by 21.3% and 45.6%, respectively. Our findings suggest that the application of the >1000 µm biosolid fractions can help to minimize adverse effects of biosolid applied in areas susceptible to potential environmental risk of contamination by heavy metals. Further assessment of potential mobility of nano-biosolid at the field scale is needed before the recommendation of including such approach during land application of biosolid.

Water Dispersible Granule

Experimental controlled release starch granules (CRSG) containing 5.3% a.i. (w/w) norflurazon or 6% a.i. (w/w) simazine retarded the leaching of both herbicides in loamy sand soil columns when compared to commercial formulations of norflurazon [80% (w/w) dry flowable] or simazine [90% (w/w) water dispersible granule]. Barley bioassays indicated norflurazon and simazine remained in the surface 0 to 2.5 cm of soil when applied as CRSG formulations and moved to a depth of 15 cm when applied as commercial dry formulations and leached with 6 cm of water. CRSG placed on pre-wetted soil columns began to release norflurazon by 7 d at 25 C or 14 d at 15 C, and subsequent leaching moved norflurazon beyond the top 2.5 cm of the soil column.
