Biochar plays a key role in nitrogen cycling, potentially affecting nitrogen adsorption and leaching when applied to soils. The laboratory experiments were conducted to investigate the adsorption characteristics of rice straw biochar (RSBC) to ammonium (NH 4 +) and nitrate (NO 3 ) and the influence of RSBC on leaching characteristics of NH 4 + and NO 3 at different soil depths using

The Problem of Leaching  Pesticide Environmental Stewardship

The Problem of Leaching Pesticide Environmental Stewardship

Leaching is the movement of contaminants, such as watersoluble pesticides or fertilizers, carried by water downward through permeable soils. Generally speaking, most pesticides adsorb to soil particles (especially clay), become immobile, and do not leach. The fate of mobile pesticides, however, can be thought of as a race between the various degradation processes and leaching to groundwater.
