Technology "NTO3-4"
 is designed for reclamation of  saline sandy soils for rice cultivation. 
Sandy soils have a high infiltration capacity and, therefore, major flooding is a challenge. 
Such soils are widespread in the Republic of  Kazakhstan and occupy large areas within the 
river basins of  Syr Darya (30%), Ili (35%) and Karatal (40%). At the present time, most of  
these soils are affected by secondary salinization. The ‘NTO3-4’ involves the regular spring 
preparation of  paddy fields (soil tillage with a plough, disc harrow and leveller followed by 
fertilization). Then, before sowing, crumbled white clay is applied to the soil surface at a 
rate 10 t/ha. The AS treatment of  rice seeds prior to sowing, the PFCA application to soil, 
flooding and irrigation techniques are similar to those in the ‘NTO3-3’ technology [3, 5].
