PFCA – polyfunctional chemical ameliorator is the core agent of newly developed methods of the
reclamation of clayey and sandy saline soils of rice fields, which helps to combat boron toxicity, alkalinity of soil
solution and alkali production by microorganisms that are present in irrigation water and the upper horizons of
paddy soils.
The reclamation technologies for clayey and sandy saline soils (‘NTO3-3’ and ‘NTO3-4’,
respectively) mean that leaching or water disposal from paddy fields are forbidden during the
entire period of rice growth. After rice plants have reached the tillering stage, drainage waters can
be used for irrigation. With a correct implementation of these technologies, rice can ripen 8-12
days earlier than usual.
The use of the above-described technologies for amelioration of saline soils has significant
agronomic and economic benefits and advantages.
