目前全国各地人民公社在普遍开展羣众性土壤普查鑑定工作的基础上正在遂步建立土壤肥料化验室;这里发表會宪修同志关于筹建化驗室的一个計划書,供大家参考。各地公社在筹建化驗室时仍应根据本身条件及具体情况建立切合实际需要的化驗室。 At present, people’s communes and communes in various parts of the country are gradually establishing a soil and fertilizer laboratory based on the mass general survey and appraisal of mass soil. Here, a plan for the preparation of a laboratory by a constitutional comrade is published for your reference. Communes in preparation for the construction of laboratories should be based on their own conditions and specific circumstances to establish laboratory to meet the actual needs.
