“…Studies on fleshy/ storage type roots like those of FR are rare. Maduakor (1993) reported that compaction decreased weight of the storage root of cassava (Manihot esculenta, Crantz) at early but not late growth stages.…”

Penetration of cover crop roots through compacted soils

Tap-rooted species may penetrate compacted soils better than fibrous-rooted species and therefore be better adapted for use in "biological tillage". We evaluated penetration of compacted soils by roots of three cover crops: FR (forage radish: Raphanus sativus var. longipinnatus, cv. 'Daikon'), rapeseed (Brassica napus, cv. 'Essex'), two tap-rooted species in the Brassica family, and rye (cereal rye: Secale cereale L., cv. 'Wheeler'), a fibrous-rooted species. Three compaction levels (high, medium and no compaction) were created by wheel trafficking. Cover crop roots were counted by the core-break method. At 15-50 cm depth under high compaction, FR had more than twice and rapeseed had about twice as many roots as rye in experiment 1; FR had 1.5 times as many roots as rye in experiment 2. Under no compaction, little difference in root vertical penetration among three cover crops existed. Rapeseed and rye root counts were negatively related to soil strength by linear and power functions respectively, while FR roots showed either no (Exp.1) or positive (Exp. 2) relationship with soil strength. We conclude that soil penetration capabilities of three cover crops were in the order of FR > rapeseed > rye.

“…As agricultural machinery is a major cause of compaction, cultivation practices are important in determining soil structure and hence water, nutrient and oxygen supplies to roots through their influence on soil strength and pore dynamics, both of which influence seedbed performance and crop establishment 76. However, contrasting responses have been reported, as Maduakor77 found that compaction increased the surface area of cassava leaves but reduced the production of storage roots, whereas Masle and Passioura57 reported leaf area decreased with increasing soil resistance (Fig. 2).…”

“…Greacen and Sands (1980) stated that the restriction of root growth do not always reduce shoot growth. Research reported that compaction significantly reduced weight of the storage root of cassava (Manihot esculenta, Crantz) at only early growing stage (Maduakor, 1993).…”

Subsoil compaction affects all aspects of soil quality which may result reduction of crop development. An experiment was conducted in a phytotron using a randomized block design to evaluate the effects of different levels of subsoil compaction on forage legume crop development and mineral nutrient acquisition and translocation in an Andisol. A clay loam Andisol was used to grow the soybean, chickpea and lentil at different levels of subsoil compaction as no compaction (0 J), medium compaction (500 J) and high compaction (1000 J). Plants were also grown under same condition in surface compaction. In this experiment, the effects of soil compaction on soil physical and hydrological properties as well recorded. The bulk density of soil increased substantially with increasing compaction. Consequently the air-filled porosity and void ratio of soil decreased with increasing compaction. Compacted soil retains more water at higher matric suction. Shoot and root weights of the plants were significantly higher at 0 J than at 500 J compaction levels indicating that soil compaction hampered normal plant growth in Andisol, irrespective of crops. Furthermore, the yields of plants tended to remarkably decrease with increasing of soil compaction from 500 J to 1000 J for both surface and subsoil compaction. Although the reduction of crop yields from 500 J to 1000 J was not always statistically significant. The severity of the detrimental effect of compaction on dry matter production could be presented as chickpea lentil soybean. The results obtained in the study revealed that apart from Ca uptake by roots, compaction hampered nutrient assimilation in both shoot and root of all the crops. Similarly, the translocation of nutrients in the shoot of the plants was adversely affected by compaction. This study revealed that the effect of surface soil compaction was less severe on the forage legume crops than subsoil compaction. We confer that the morphological and physiological changes in three legume forages differed in both surface and subsoil compaction.
