A solar collector for soil disinfestation

  • R. Ghini

Abstract

A solar collector to be used for disinfestation of substrates for plant propagation is described. At a high solar radiation intensity (more than 1 cal cm−2 min−1), one day of treatment was sufficient for disinfestation of soil infested withSclerotium rolfsii, Sclerotinia sclerotiorum, Fusarium solani f.sp.phaseoli orPythium aphanidermatum.

Treatment of soil in the solar collector strongly reduced the total numbers of fungi, bacteria and actinomycetes. The nutrient status of the soil was only slightly changed and did not result in an effect on plant growth.
