全世界土壤中和苏联主要农业地区耕作土壤中腐殖质和氮的贮量现在已有足够的关于地球上各类土壤中腐殖质的百分数含量的资料可以据以计算出土壤中腐殖质的贮量。若泥炭、腐泥以及其他自然物体中(其中包括土壤腐殖质)有机碳的总含量是n×10~(15)吨,则陆地上腐殖质部份的含量应为2.4 ×10~(12)吨。作者根据邱林的资料,自身研究工作的总结性资料以及文献中有关苏联土壤方面的资料,对全世界各个生物气候区一米厚土层的腐殖质
The amount of humus and nitrogen in tillage soils in the world’s soils and in the main agricultural areas of the Soviet Union There is now enough information on the percentage of humus in soils of all kinds on the earth that the amount of humus in soils can be calculated. If the total content of organic carbon in peat, sapropelin and other natural objects (including soil humus) is n × 10-15 tons, the content of humus on the land should be 2.4 × 10-12 tons. Based on the data of Qiu Lin, the summary data of their own research work and the literature on the soils of the Soviet Union, the author analyzed the humus quality of one meter thick soil layer in each bioclimatic zone in the world
