The index is a tool to help conservation planners, landowners/land users and others to evaluate the current risk from P reaching surface water from a specific site, and to determine factors which dominate the risk due to P transport to surface waters. It will also assist landowners/land users in making management decisions to reduce the risk. The P-index has an erosion component, which considers shell and rill erosion, P enrichment, total soil P, filter strip, sediment delivery, distance to a stream, and the long term biotic availability of particulate P in surface water ecosystems. . A runoff component considers water run-off based on a modification of the runoff curve number, soil tests, rate time and method of P application. An internal drainage component considers the presence of tiles, water flow to tile lines, surface water recharge to subsurface flow, and soil tests. The P-index is a tool, that directly can assess the risk of P leaching, and therefore whether there is a need for not spreading livestock manure on a certain field. Establishing of non-cultivated buffer zones along streams, and terraces in the steep fields, would dramatically reduce the P-index. The whole index is a formula, which is easily calculated annually once the specific parameters for the given field have been determined.

Certification can happen on basis of an initial training of 6 hours + test, and a 2 hours annual update + test. It is expected the training will have a reduction effect on leaching, because it will ensure persons who handle livestock manure understands how to secure a precise spreading and how to avoid leakage.
