The present study, an integral component of the Natural Resource Conservation Project (NRCP) under the Environmental Rehabilitation in NWFP and Punjab (ERNP) programme, was initiated to evaluate the fertility status of the soils and orchard (apple, peach, pear, citrus and plum) nutrition of Galliyat area of Abbottabad district, representing three units (Birote, Boi and Thai). A total of 74 soil samples (0-30 cm depth) from 48 sites in Birote unit and 13 sites each from Thai and Boi units and plant samples from 50 sites in Birote and Thai units were collected. The physico-chemical properties of soils showed that texture of soils of all the units were loam and silt loam with dominant silt fraction suggesting removal of clay content from the upper soils due to soil erosion leaving the higher contents of sand and silt. The soils were neutral to slightly alkaline, pH ranging from 6.8 to 7.9 and non-saline. The soils were moderately calcareous, with medium to high organic matter (>1%). The results indicated that more than 50% soil samples were deficient in N concentrations and 35.4, 46.2 and 53.8% samples of Birote, Boi and Thai units contained medium P concentrations (
