STUDIES IN SOIL FUMIGATION: PRELIMINARY OBSERVATIONS
Annals of Applied Biology, 1937SUMMARY Results of preliminary tests of possible methods of investigating the factors controlling the distribution of fumigant vapour in soil are described. Sufficiently uniform and reproducible conditions of pore space in soil may be secured by packing at definite pressures and with a controlled moisture content.

The chloroform fumigation-extraction method for determining soil microbial biomass is commonly applied at soil moisture (SM) levels of 40–50% water-holding capacity (WHC).

Effect of Fumigation on Soil Aggregation
Soil Science Society of America Journal, 1952Abstract A study was made of the effects of several soil fumigants in moderate and high dosages and of steam sterilization on the aggregation of the <50 µ particles of five soils. The fumigants were injected into dry soil in large screw cap bottles, water sufficient to bring the moisture content of the soil to 50% of capacity was ...

Fumigation of potato soils in Washington
American Potato Journal, 1965Partial soil sterilization with Picfume, Vapam, Vorlex, Terraclor, Telone and combinations of Telone and Picfume have been included in studies for one or more years between 1960 and 1963. All the chemicals tested except Terraclor resulted in yield increases statistically and economically larger than the yields of potatoes produced on the untreated ...

Economic Effects of Banning Soil Fumigants
1988Producers who formerly used fumigants to control soil-borne pests would be worse off by $100-$200 million per year, despite higher prices, if soil fumigants were banned for citrus fruit, potatoes, tomatoes, tobacco, and a few other crops, because crop output would decline sharply.

Bacterial community structure in fumigated soil
Soil Biology and Biochemistry, 2014Abstract Soil microbial biomass has been determined since the mid 1970's by the chloroform fumigation incubation technique as proposed by Jenkinson and Powlson (1976). The microbial biomass C can be determined by subtracting the CO2 emitted from an unfumigated soil (mineralization of soil organic matter) from that emitted from a chloroform fumigated ...

Bacterial colonization of a fumigated alkaline saline soil
Extremophiles, 2014After chloroform fumigating an arable soil, the relative abundance of phylotypes belonging to only two phyla (Actinobacteria and Firmicutes) and two orders [Actinomycetales and Bacillales (mostly Bacillus)] increased in a subsequent aerobic incubation, while it decreased for a wide range of bacterial groups.

The fungus flora of fumigated soils
Transactions of the British Mycological Society, 1968A study was made of the extent to which Trichoderma recolonized fumigated soils with a view to biological control of root disease fungi. Treatment of Kettering soil with allyl alcohol, chloropicrin, dichloropropene—dichloropro-pane mixture (D-D), methyl bromide, sorbic acid or acetylenedicarboxylic acid promoted the development of dominant populations ...
