Other claims from this paper (7)

Intervention effect Increasing soil bulk density reduced root length from 20.4 to 8.4 m per pot stratum.
Association Decreased root development was associated with decreased tillering.
Observation The three ryegrasses had similar total root length, herbage yield, and tiller numbers.
Intervention effect Yatsyn 1 root length, herbage yield, and tillering were not significantly reduced with increasing bulk density.
Observation Yatsyn 1 was least sensitive to soil compaction relative to NZA1 and NZA3.
Observation Adverse root and shoot growth effects occurred below 1.3 Mg/m3.
Observation Growth reductions may occur at lower bulk density in soils from volcanic parent material.
