Other claims from this paper (9)
- Intervention effect Alfalfa-brome yields increased significantly with liming under NPKS and PKS treatments.
- Intervention effect Alfalfa-brome N, P and cation uptake increased significantly with liming under NPKS and PKS treatments.
- Association The liming-related increases in alfalfa-brome were linked to higher N uptake in subsequent wheat and oat crops.
- Intervention effect In the Check and Manure treatments, liming had no effects on marketable yields, N or cation uptake in all crops.
- Intervention effect In the Check and Manure treatments, liming had no effects on grain protein and N surplus in cereals.
- Intervention effect Soil acidification rates were greater in NPKS and PKS than in Manure and the Check treatments, regardless of liming.
- Observation Cation exports in alfalfa-brome exceeded those in cereal crops.
- Association Higher cation exports in alfalfa-brome are associated with increased H+ release by alfalfa roots.
- Association The authors suggest that soil acidification rates have likely increased with diversified crop rotations and fertilizer use, coinciding with conservation tillage.
