N, P, and K Budgets and Changes in Selected Topsoil Nutrients over 10 Years in a Long-Term Experiment with Conventional and Organic Crop Rotations

<table>Calculated soil system budgets of N, P, and K for the years 2001–2010 plotted, respectively, against ignition loss (subplot A), P-AL (subplot B), K-AL (subplot C), and K-HNO<sub>3</sub> (subplot D) for the six cropping systems CA1 (conventional arable: ○), CA2 (conventional arable, environmentally sound: □), OA (organic arable: ∆), CM (conventional mixed dairy: ●), OM1 (organic mixed dairy: ▲), and OM2 (organic mixed dairy with 75% clover ley: ■).</table>
