Functionalized charcoal (CHox) incorporated into urea is known for its ability to reduce NH3 volatilization and increase agronomic efficiency. However, it is important to optimize the functionalization process and to elucidate its relationship with the physicochemical properties of CHox for N supply. Thus, charcoal obtained from eucalyptus wood was...

... apparent N recovery efficiency of corn plants was between 75.22 and 84.30 % when fertilized with NH 4 NO 3 (Table 9), while for other fertilizers, it was between 50.21 and 83.48 %. However, among fertilizers, the apparent N recovery efficiency was statistically equal (Table 9), and in each fertilizer, statistical difference was only found among doses to U-AH CH and NH 4 NO 3 . ...

Rice straw is a low-density crop residue. It is produced in huge quantities every year across the country. Therefore, the management of rice residue has become a problem for farmers. Farmers have to vacant the field as early as possible for sowing of the next crop. Hence, they go for the burning of crop residue and now it has become the common prac...

Denitrification and NH3 volatilization are the main removal processes of nitrogen in coastal saline soils. In this incubation study, the effects of wheat straw biochar application at rates of 0, 2, 5, 10 and 15% by weight to saline soil with two salt gradients of 0 and 1‰ on denitrification and NH3 volatilization were investigated. The results show...

The use of nitrogen fertilizers to enhance crop growth tends to increase every year. In addition, as eco-friendly agriculture is emphasized, organic fertilizers are preferred over inorganic fertilizers. However, since most of organic fertilizers in South Korea use imported ingredients, an alternative ingredients is needed. Biochar is an eco-friendl...

Purpose Laboratory incubation experiments using ¹⁵N stable isotope labeling and acetylene suppression techniques were conducted to compare the autotrophic nitrification and heterotrophic nitrification rates with the addition of swine manure (SW) and swine-manure-derived biochar (SWB) in two paddy soils. Materials and methods SW and SWB were applie...
