A contribution to our knowledge of the Indian soil actinomycetes

  • Jagjiwan Singh

Summary and Conclusions

It can be said that Actinomycetes do not show any periodic phenomenon such as we find in the other groups of soil organisms. The curve on Fig. 1 shows that the numbers of Actinomycetes seem to scatter about a mean value between four to eleven millions per gram of dry soil.

In the Punjab soils the numbers of Actinomycetes is slightly greater than those reported by the American and European workers.
