Abstract:: Accurate information about current soil nutrient concentrations in orchards is necessary for making recommendations about future fertilizer application rates. Additional information is needed about the amount of soil P surplus in the orchards of Shaanxi Province, which is the main apple and kiwi production region in China. Analysis of P inputs and P loading is important for P management in orchards. The objective of this study was to quantify both the P application rates and the amount of surplus P in orchards in Shaanxi Province. The information was collected from farmer interviews and an agricultural statistics database. The data were analyzed using the P balance method. The results showed that P fertilizer application had the excess and deficiency phenomenon. The P fertilizer application rates averaged 366.1 kg/hm² among the orchards surveyed in this study. Manure application accounted for 72.8 kg P₂ O₅/hm², nearly 20% of the orchards existed phosphorus deficiency, more than 80% of the orchards had phosphorus surplus. Nearly, 43.1% of the orchards had a phosphorus surplus of more than 300 kg P₂ O₅/hm². Among the different kinds of orchards, kiwi orchards had the highest rate of surplus phosphorus 472.3 kg P₂ O₅/hm², the grape orchards and apple orchards had the rates of phosphorus surplus of 365.9, 355.6 kg P₂ O₅/hm², respectively. In irrigated areas of central Shaanxi Province, the P₂ O₅ surplus averaged 351.8 kg/hm² which was greater than the surplus amount in the Weibei rainfed region. High phosphorus inputs to orchards in some regions of Shaanxi Province led to high phosphorus loading, which will increase environmental risks in the region.
