No K effect occurs on panion crops, wheat, maize, beet and potato39。 The potassium contents in Gansu corridor irrigated desert soil and its fertilization effect of current season SUO Dongrang1, LI Duozhong2 (1.

P increases rapeseed yield grown on paddy soil derived from quaternary red clay (available P2O5 mg/kg)by ～ times, whereas alluvial deposit and red sandstone(available P2O5 mg/kg) ～ times. Pincreases rice yield grown on paddy soil derived from quaternary red clay and red sandstone by %～% and %～ % respectively. (2) Relative agronomic effectiveness of Gafsa ground phosphate rock(GPR, %～ %) is much higher than that of Kunyang GPR(%～ %), its fertilizer effect is almost same to that of single superphosphate (SSP). (3)Increased productive value by P from rapeseed (2 839～ 5 307 RMB Yuan/hm2) is much more than that from rice(224～ 742 RMB Yuan/hm2). (4)The value and cost ratio(VCR) from various P resources is in order: Kunyang GPR＞ Gafsa GPR＞ SSP.
