Aprioct (Prunus armeniaca L.) is the main fruit in Ladakh region. Soil nutrients play a vital role in the growth, development and yield of apricot tree and the information on the nutritional status of an area can go a long way in planning judicious fertilizers and soil management practices to develop economically viable alternatives for the orchardists. Twenty one orchards with uniform age and vigour were selected and surveyed (simple random survey) for the purpose of collection of soil and leaf samples in District Kargil. The soil samples were collected from the three different depths viz., 0-20 cm, 20-40 cm and 40-60 cm. The soils were mostly sandy loam with sand, silt and clay with neutral to alkaline in reaction. Most of the soil samples were within the safe limit of salinity and were grouped under class A <0.5 dsm-1. Organic carbon is almost low irrespective of all locations. While in available nutrients contents nitrogen is low at all locations, phosphorus is adequate and potassium is varied from medium to high category. The available calcium and magnesium did not reveal a definite pattern along the depth. The available sulphur content in these soils was sufficient and did not exhibit any definite trend in its vertical distribution. The DTPA-extractable zinc was found to be low, copper was found to be optimum in 95.23% soil samples. Iron was found low in 42.85% soil samples and medium to high in 57.14% soil samples. Manganese was found to be low in almost all samples with the surface soils containing higher amount than the sub-surface soils. All the micronutrients cations showed a decreasing trend with the increase in soil depth.
