Nutrient management strategies in Gansu province

IPNI-1999-CHN-GS4

Yield limiting factors of nutrients in soils on Gansu province, 2001 To determine yield-limiting, soil nutrient factors in Gansu province, four pot experiments with sorghum and four field experiments with corn were conducted in 2001 based on the PPI/PPIC ‘Systematic Approach’ to balanced fertilization. The test soil was irrigated desert soil from the Hexi Corridor, which is the important area for agricultural production in Gansu. Read more

1999

Nutrient management strategies project in Gansu province, 1999 There was no obvious response of potash added to corn in Mingqin county, northern Gansu and Lanzhou in 2000. Balanced fertilizers with 428-214-371-13 kg N-P2O5-K2O-Zn/ha vs. K0 significantly increased apple yield by 2563 kg/ha or 19. 1% in Qing-an county, southern Gansu.
