The research was carried out at the Agricultural Scientific Research Center in The Qamishli, samples were taken in early 2017, according to the design of a factorial experiment (2 factors) where the pattern of agriculture is conservited and traditional represnts major transactions, whereas the secondary factors are the type of grown plant (barley, vetch). In this research, Potasium quantity was measured in a different forms (melted, exchangeable, and unexchangeale) as a first stage by distilled water, acetate and chlorine water respectively for each of the soil applied to conservation agriculture and soil applied to traditional agriculture and bore (control treatment)., After discussing the results we obtained the following results That conserved agriculture coefficients surpassed traditional agriculture coefficients in all treatments in mutual and non reciprocal potassium estimation as well as for dissolved potassium in barley Where the highest potassium value was mutual for conservation agriculture And reached (429.4) mg/kg compared to (266.7) mg/kg traditional agriculture As well as (316.1) mg/kg for the barley portfolio compared with (225.9) mg/kg for barley, As for dissolved potassium in vetch transactions, its value was observed in the traditional coefficients of the first three depths compared to the conservation agriculture treatments This can be attributed to the method of cultivation and the nature of the root mass of the vetch crop.
