ABSTRACT
The distribution of soil structural units controls theavailability of oxygen, water, and the
resistance to penetration by shoots and roots in seedbeds created by tillage. The objective of this study
was to determine the effects of variation in soil aggregate size distribution on early growth and
evapotranspiration of tomato. Fresh and dry matter of tomato, root length and evapotranspiration,
determined 5 weeks after planting, were evaluated in a green house experiment with packed soil
aggregates sieved from an Entisol. A complete randomized design of 3 different aggregate size
distribution (
