Technology "NTO3-1"
 is designed for amelioration of  strongly saline loamy soils. At the core 
of  this technology lies the use of  recently developed small-volume ameliorators that produce 
synergistic effects in combination with certain organic additives (rice straw), water supply, soil 
tillage and fertilization. Such ameliorators are applied to soil once in every 7-10 years. The 
‘NTO3-1’ is intended for two types of  rice fields: 1) on previously cultivated strongly saline 
and alkalize soils and 2) on virgin soils and soils with secondary salinity.
