Compaction of hydromorphic black soil by IMT-5360 heavy tractor wheels

, : Compaction of hydromorphic black soil by IMT-5360 heavy tractor wheels. Savremena Poljoprivredna Tehnika 13(4): 133-137

The problem of compaction of hydromorphic black soil by heavy tractor wheels during ploughing is assessed. Changes in soil compaction, density and soil porosity are examined.

Bacterial spores can remain dormant for years, yet they possess a remarkable potential to rapidly resume a vegetative life form. Here, we identified a distinct phase at the onset of spore outgrowth, designated the ripening period. This transition...

In contrast, Enalapril, another ACE inhibitor with antih...
