Overview of Long-Term Field Experiments (LTE)

This LTE overview map, developed under the BonaRes initiative at ZALF, currently encompasses data from +570 agricultural experiments with a duration of at least a minimum of 20 years. The following networks are included: EJP SOIL (European Joint Programme), GLTEN (Global long-term experiment network), ILTER (International long-term ecological research), IOSDV (International Organic Nitrogen Fertilization Experiment), NLFT (National Long-term Fertilization Trials, Hungary), RetiBio 2 (Italy).

(You can get easy access to your LTE of interest by using the categories as a filter criteria.)
