The nutrient status of soil and leaves in navel orange orchards in Longchuan county，Yunnan province，can provide a theoretical basis for the fertilization management of navel orange orchards.Soil (0-20 and 20-40 cm soil layers) and leaf samples were collected to determine the nutrient abundance and deficiency status，and the soil integrated fertility indices were calculated in different soil layers.In the 0-20 cm soil layer，the average soil pH was 5.43，while 31.7% of the orchard soil pH was 5.5-6.5.More than 80% of the soil organic matter，available phosphorus，available potassium and trace element contents (except available copper) were at suitable or above levels； more than 60% of the soil exchangeable calcium，exchangeable magnesium and available copper contents were at the deficient level.In the 20-40 cm soil layer，the soil pH variation was 4.22-7.49.For soil organic matter content，91.4% of the navel orange orchard was >15 g·kg-1； the contents of exchangeable calcium，exchangeable magnesium and available copper were low； and other nutrients were at appropriate and above levels.The soil pH，available potassium，exchangeable magnesium and trace elements (except available iron) in the 0-20 cm soil layer were significantly higher than those in the 20-40 cm layer.There was no significant difference in other indicators between the two soil layers. The content of phosphorus, potassium, calcium, and trace elements in the leaves was at an appropriate or above level. The proportions of foliar nitrogen and magnesium content at insufficient levels were 49.3% and 87.3%，respectively.The average soil integrated fertility index for the 0-20 and 20-40 cm soil layers was 0.57 and 0.46，respectively，which were at the medium level.In summary，the soil fertility level of the navel orange orchard in Longchuan county was moderate，the soil pH was low，the content of soil exchangeable calcium，magnesium and available copper was insufficient，other nutrients were suitable，the content of leaf nitrogen was low，the magnesium content was seriously insufficient，and the content of other nutrients was at an appropriate level.Therefore，lime or alkaline fertilizer should be appropriately applied to adjust the soil pH，and calcium，magnesium and copper fertilizers should be sprayed on soil or leaves to improve the soil fertility level of navel orange orchard and promote the quality and efficiency of navel orange.
