| Abstract |
The study reports on the nature and action of phytotoxic substances that are released to the soil from decomposing plant residue. The plants consisted of crops such as barley, rye, wheat, beans, and lettuce. Both the favorable and unfavorable effects were observed. Decomposition products in field soils were analyzed and some of the more active ones were chemically defined. The toxicities of these products on seedlings and roots of field-grown crops were tested under such varying conditions as time, moisture, aeration, temperature. The effects of these residues on plant pathogens were also observed, and the role of these organic residues on the epidemiology of seedlings was determined. (Modified author abstract) |
