Sewage sludge compost long-term experiment
This experiment has been added by the GLTEN Curators using existing published sources.
- Local identifier
- Hungary, Nyíregyháza
- Years operational
- 2006—
- Objective
- The experiment was established to study the effects of regular application of sewage sludge compost on acidic sandy soil.
- Description
- The 0, 9, 18 and 27 t/ha doses of sewage sludge compost are studied in a small plot (12 m x 19 m) experiment. The compost was designed for sandy soil with co-composting of organic matter (sewage sludge and straw) and minerals (zeolite and bentonite). The experiment was set up in five, not-randomized blocks with three test plants in all-year crop rotations.

- History
- The 1.4 hectares of the experiment has been used for crop production more than 100 years. Soil pH was acidic (about pH(KCl) 4), humus content was low (about 0.8%).
- Management
- Soil is conventionally managed in terms of weed and pest management while chemical fertilizers are not used. The applied sewage sludge compost was planned for acidic sandy soils with straw, bentonite and zeolite addition to the sewage sludge in the course of composting process. Test plants are sawn in crop rotation. 2003-2017 maize, green pea and triticale were used, while from 2018 maize, hairy vetch with rye and rye are sawn yearly. Treatments are 0, 9, 18 and 27 t/ha sewage sludge compost ploughed into the soil in the autumn of every third year.
