7/8/?020 IPNI Estimates of Nutrient Uptake and Removal <br /> 03 Dec 2012 <br /> IPNI Estimates of Nutrient Uptake and Removal <br /> This page lists estimates of nutrient uptake and removal for different crops grown in different countries of the world in both <br /> Imperial/U.S.and Metric units, and represent what IPNI scientists believe to be the best estimates of typical values to date. All tables <br /> are used within included in our 4R Plant Nutrition Manual.and are used within our Crop Nutrient Removal Calculator i-OS app <br /> (PlantCalc)and its web-based version. <br /> These tables are updated as new data become available.You can download these tables in pdf format(see'Additional Resources' <br /> on left). <br /> Imperial/U.S. Unit Tables <br /> Table 4.1 Total nutrient uptake*by selected crops (Last modified: May 2014). <br /> --Ib uptabe/harvested urtit'- <br /> Crop•*w Room Harvested UnitN -- PzO, Kao - - S -- <br /> Alfalfa(DM) Argentina ton 64 11 60 7.0 <br /> Barley Argentina bu 1.3 0.44 13 02 <br /> Bermudeg ass USA ton 46 12 60 <br /> Cancla China bu 22 1.4 4.4 <br /> Chickpea India cwt 4.6 0.84 4.9 <br /> Com USA bu LO 0.54 1,4 <br /> Grape China ton 11 10 17 <br /> Mustard India cwt 3.3 15 11 14 <br /> Oranges Chino ton 5.3 16 72 <br /> peach Chin ton 9.0 3.0 10 <br /> Peanut India ton 126 23 74 7.8 <br /> Pear China ton 10 4.0 10 <br /> Peas,green India ton 84 29 62 &6 <br /> Potato Australia cwt 0.49 0.21 12 <br /> Rice USA bu 0.71 0.38 11 <br /> Safflower India cwt 3.9 0.84 22 L3 <br /> Sorghum India cwt 2.2 L3 3.4 <br /> Soybean USA bu 49 11 2.3 <br /> Sugar tact China ton 9.6 28 19 <br /> Sugarcane China ton 3.6 0.72 4.2 <br /> Sunflower Argentina cwt 4.0 2.5 3.5 0.50 <br /> Tobacco China Cwt 3.9 12 71 <br /> Tomato India ton 5b 2.6 7.6 <br /> Wheat,spring USA bu 22 0.76 1.6 <br /> Wheat,winter USA fru 1-9 1 0.68 2.0 <br /> *Total nutrient uptake refers to the quantity of nutrient accumulated in the above ground portion,and harvested portions,of the plant by the time of <br /> sampling usualty phyWogical maturity or when uptake is at its maximum- <br /> **Reported nutrient uptake coefficients may vary regionally dependingon growing condaoons.Use locally available data whenever possible. <br /> ***DM=dry matter basis:ctherwtse moisture content is standard marketng convention or at tire stated moisture content. <br /> Last modified May,2014. <br /> Table 4.5 Nutrient removal*by selected crops (Last modified: May 2014). <br /> www.ipni.net/article/IPNI-3296 1/6 <br />
