Other claims from this paper (10)
- Intervention effect Mineral fertilization gave the highest maize grain yield (7.4 ± 0.7 Mg ha−1) relative to 100% compost fertilization.
- Intervention effect Maize grain yield was lowest under 100% compost fertilization (5.2 ± 1.0 Mg ha−1), relative to mineral fertilization.
- Intervention effect Wheat grain yield did not differ significantly among control, mineral, compost and mineral/compost fertilization (average 5.1 ± 0.7 Mg ha−1).
- Intervention effect Sunflower grain yield did not differ significantly among control, mineral, compost and mineral/compost fertilization (average 2.3 ± 0.3 Mg ha−1).
- Intervention effect Cumulative crop yield over the three years was not affected by compost type.
- Intervention effect Cumulative crop yield over the three years was affected by fertilization treatment, highest with mineral and with 50% compost plus 50% mineral fertilization.
- Intervention effect Compost application had no relevant effect on soil organic carbon.
- Intervention effect Under 100% compost fertilization the crops did not take up a large amount of the N supplied.
- Observation Compost has good fertilization properties in this three-year crop succession.
- Observation The amendment property of compost was not relevant, probably due to the low rates applied and the short experimental period.
