The survey found that, pine needle compost was widely applied in Heqing County, farmer households with compost accounted for 91.76% of the total households, and among which, farmer households with the pine needle compost accounted for 96.82% , the total compost reached 7493730 kg, the average household compost reached 3333.51 kg.
