Description Coffee growing areas in Andhra Pradesh and Orissa (non-traditional area - NTA) are characterized by undulating topography with terraced slopes having narrow valleys with scattered coffee farms across the elevation of the Eastern Ghats of Vishakhapatnam (Andhra Pradesh) and Koraput (Orissa) districts. Under this situation plant available nutrients will become non-available and the nutrients are stored in several pools as inorganic and organic forms in soil exchange complex are very much essential for coffee plants for its growth and development. Hence, a study was conducted to know the soil nutrient status of coffee growing region of NTA. A total of 693 surface soil samples were collected at depth of 22cm randomly from each coffee growing mandals of NTA and assessed the nutrient status (soil pH, OC, available P and K) at Regional Coffee Research Station, Narsipatnam. Results of the soil test results indicated that most of the Arabica coffee soils of NTA are acidic in reaction (72 %) and soil pH > 6.0 in these soils was 28 % in the tested soils. Plant available phosphorous (P) in the soil is low with 33 % soils and 46 % of the soils are medium in range. However, only 21 % of the soils tested are high in available phosphorous content in these soils. The majority of the soils of this region are high in available potassium about 54 % and 31 % of the soils are medium in range but only 15 % of the soils are low in available K status. Coffee soils of NTA are rich in organic carbon status and almost 47 %. 33 % of the tested soils are medium in range but 19 % of soils were low in organic carbon status. Soils are slightly acidic in reaction and were rich in organic carbon and available potassium status.
