Conteúdo: | One can examine the physical characteristics of soil such as air space, permeability to air and water, and infiltration rate found after compaction by field traffic. The levels believed satisfactory for plant growth and economic management indicate that excessive compaction can occur. The agronomist's interest in soil compaction is to investigate (a) methods by which excessive compaction might be avoided, (b) methods by which existing excessive compactness may be reduced, preferably in a more than temporary manner, and (c) methods by which satisfactory yields can vbe obtained in cases where prevention or amelioration of compaction is unerconomical. Investigations having objectives (a) and (b) involve the research worker in soil strength studies. Information on deformability as a function of soil wetness, particle-size distribution, organic matter content, soil mineralogy, level and stability of aggregation, and other soil characteristics is needed to predict the reaction of soil to a given loading or manipulation. Avoiding travel in wet fields is a long standing recommendation, but farm produt market fluctuations and demands of pest control programs often overrule this consideration. Hence, methods of strengthening soils by controlling variables other than wetness need to be sought. Characterization of deformability should be useful iin this goal and also in the design of farm implements and tractors which will accomplish the desired purpose with a minimum of incidental excessive compaction.
