Zeolite as a means of environmental management

Khanal Arjun(1) Paudel Pratima(2) 1 Project Coordinator/Research Associate at Center for Environmental and Agricultural Policy Research, Extension and Development (CEAPRED) (E-mail: arjunkhanal15@gmail.com) 2 Data entry officer at Center for Environmental and Agricultural Policy Research, Extension and Development (CEAPRED) (E-mail: Paudelpratima10@yahoo.com) Abstract Seed drying beads are modified ceramic materials (aluminum silicates or “zeolites”) that specifically absorb and hold water molecules very tightly in their microscopic pores. The beads will continue to absorb water until all of their pores are filled, up to 20 to 25% of their initial weight. Seven experiments were carried out using zeolite seed Drying Beads® to dry ...

Whilst everyone knows that the nematode is a scourge on agriculture, few farmers realise that it can be effectively controlled by incorporating zeolite. Conventional chemical control is not only costly but also has serious environmental consequences. Meanwhile, organic methods are not as effective. The problem is particularly acute with the following nematodes: Meloidogyne, Heterodera and Globodera. Many nematodes feed on bacteria, fungi and soil organisms, whilst others are parasitic and feed on animals or plants. Nematodes weaken plants and make them less resistant to other attacks. This can result, for example, in root rot. The problem is exacerbated in greenhouses ... Read more
