Soil series of Charsadda being of alluvial nature, grayish brown, coarse to medium sub-angular blocky, slightly calcareous and silt loam
However, the best soils are sandy loam or silt loam
. Application of nitrogenous fertilisers is based on soil type.
The three soils used in this study were the Talparo series (clay loam), Piarco series (silt loam
) and Arena series (loamy sand).
The survey was conducted from January to December, 2016 by applying line transect technique in eight types of soil (sand, loamy sand, sandy loam, sandy clay loam, loam, clay loam, silt loam
, silty clay loam) to determine six soil properties (plant biomass, saturation, electrical conductivity, pH, organic matter, phosphorus and potassium) in Pothwar Plateau (250 km long and 100 km wide).
The results showed that the dominant texture in the profiles were clay and silt loam

Texture of Gojra site soil is predominantly silt loam
and varies from loam to silt loam
throughout the soil profile of 0-75 cm.
All soils samples were categorized as silt clay, silt loam
, loam and silt clay loam.
Much of the vineyard soil in the region is composed of deep, rich silt loam
, which works well for Riesling and Chardonnay but promotes very vigorous growth with Cabernet Franc.
In Kansas, even dirt is official: Harney silt loam
is the state soil.
The soil used in this research was silt loam
and in regards to salinity and copper content had no restriction for growing sunflower.
