Description T-8615
A study was conducted in farmers‘ fields of Rai block of Sonepat district to
study the long term impact of two widely adopted resource conservation technologies
(RCT‘s) namely bed planting and zero tillage on structural properties of soils of
recent alluvial plains of river Yamuna. Vegetables growing bed planted areas mostly
had medium texture soils, easy access to market and availability of fresh water. Zero
tillage was practiced mainly by farmers to timely sow wheat in fine textured soils and
low lying areas where soils do not dry even in mid-November.
Aggregate mean weight diameter by dry sieving and wet sieving (DS-MWD
and WS-MWD) under different RCT‘s were studied to compare structural condition
of the soils under continuous use of these technologies. Other important structural
indices such as dispersion ratio (a measure of ease of dispersion) (DR), colloid
moisture equivalent ration (a measure of ease of percolation) (CMER), erosion ratio
(EI), stability index (SI), clay ratio (CR) were also studied to monitor the
susceptibility of soil to erosion.
Results revealed that in the surveyed villages under conventional tillage, the
average magnitude of DR and ER were 0.58 and 0.82, respectively, and CMER was
