| | KRASILNIKOV: PART II, section 3 |
 | | We have studied the streptomycin adsorption capacity of the podsol soils (Experimental Station Chashnikovo, Moscow Oblast') of cultivated and noncultivated soils. |
 | | In podsol it can be detected in the free state after 20 hours, in the adsorbed state after 5 days In the serozem the free antibiotic is preserved for no more than two days, while in the adsorbed state it retains its activity for more than seven days. |
 | | For example, in podsol soils under two-year clover and frequently fertilized we have found 1,000-3,000 millions of organisms per gram of soil in the rhizosphere and in the zone outside the roots, 300-800 million organisms per gram of soil. |
