Decay types observed in small stakes of pine and Alstonia scholaris inserted in different types of unsterile soil
T Nilsson, G F Daniel
The attack of various wood-degrading microorganisms occurring in mini-stakes of pine and Alstonia scholaris buried in various types of unsterile soil was studied. Attacks by white rot, brown rot, soft rot, erosion bacteria, tunnelling bacteria and actinomycetes were found. Soft rot occurred in all soils, whereas attack by white rot and especially brown rot and erosion bacteria was rare. The type of soil influenced the occurrence of attack by tunnelling bacteria and actinomycetes. The former were mainly associated with horticultural soils whereas the latter were associated with soils from coniferous forests.
