Description Composite surface (0 to 0.15 m) soil samples were collected from vegetable growing fields in midhills
subhumid and highhills
wettemperate
subagroclimatic
zones of Himachal Pradesh. The soils in wet temperate zone of Himachal Pradesh were more acidic (pH
5.2 to 6.8) in contrast to soils in mid–hills subhumid zone (pH 5.8 to 7.5) sandy loam to clay loam in texture, medium to high in organic
carbon content. Soils were medium in availableN,
low to medium in availableP
and medium to high in availableK.
In 1
subhumid
zone, the DTPAextractable
micronutrients ranged between 0.64 to 11.0 mg kg for Zn, 0.14 to 1

2.80 mg kg for Cu, 10.6 to 70.8
mg kg for Fe and 2.1 to 34.9 mg kg for Mn, while in wettemperate
zone 1

between 0.44 to 2.06 mg kg forZn, 0.02 to 3.60 mg
kg for Cu, 22.8 to 96.6 mg kg for Fe and 2.5 to 40.0 mg 1
kg for Mn. Soils in some parts of wet temperate zone of Himachal Pradesh
are inherently low in DTPA extractable Zn (19%), Cu (13%) and Mn (6%) while parts of sub humid zone are low in DTPAextractable
Cu
(16%) and Mn (5%). All the DTPA micronutrients showed positive correlation with organic carbon. DTPAFe
and Mn showed a negative
correlation with soil pH. Among mechanical separates, the availability of DTPACu
and Mn was higher with finer soil fractions and
decreased with coarser ones and reverse relation was observed with DTPAZn.
