Long term effects of different horti-pastoral systems
viz., Emblica officinalis
Chrysopogon fulvus Pennisetum
(aonla) alone, aonla + (dholu), aonla +
(hybrid napier) and aonla + (perennial arhar) were
purpureum Cajanus cajan
evaluated in comparison to agricultural cropping system on soil compaction in
degraded lands of Shivaliks. The cultivated agricultural field with traditional
cropping and tillage system over the years had a compacted sub-surface layer of 10
cm thickness within 10-20 cm depth with compaction values in the range of 1821
to 1973 kpa at field capacity. Under horti-pastoral systems, magnitude of
compaction at various depths varied with the system. Cultivation of aonla alone
for 14 years reduced the maximum level of soil compaction in 5 to 20 cm depth
range from 1973 to 1610 kpa. Cultivation of perennial grasses as intercrops in
aonla had synergetic effect based on their rooting system and caused further
reduction in compaction values up to 784 kpa in 10-30 cm deep layers. Aonla +
perennial arhar had the lowest soil resistance to penetration in 7.5 to 20.0 cm depth
while hybrid napier based system was effective beyond 20 cm depth also. Hybrid
napier had more vigorous and deep root system than other grasses. Technique of
pit making before transplantation of aonla proved very effective in maintaining
soil compaction at optimum level and offset any adverse on aonla growth due to
sub-surface compaction. Horti-pastoral systems proved better than field crops in
conserving and rehabilitation of degraded soils. The biological systems are
more effective than mechanical measures like chisel ploughing due to long
duration effects
