Controlled
Release
Controls are widespread in Europe to control volumes of water
soluble fertilizer leaching losses. North America and other
parts of the world are heading in the same direction. The
Mississippi and Rhine river watershed are two good examples
of major agricultural regions environmentalists are targeting
fertilizer leaching losses. Much attention is being paid to
the 'dead zone' in the Gulf of Mexico - which in part is attributed
to fertilizer leaching losses.
Because elemental sulphur bentonite formulations convert to
plant available and water soluble sulphate sulphur over a
period of time, the sulphur is available to the crop throughout
the growing season and is much less likely to be lost due
to leaching.
Most elemental sulphur formulations can be certified as Organic
as well.
