In this study, the goal was to investigate the effect of different cover crops on the soil aggregate stability and soil phosphatase and their relationship. A laboratory pot experiment was established in which four cover crops were grown (Secale cereale L., Fagopyrum esculentum L., Brassica napus L. and Hordeum vulgare L.) for 33 days in sandy loam soil. Afterwards, the above-ground biomass was cut and incorporated in equal quantities (0.2 g C kg–1 of soil or 176 kg C ha–1) in the same soil and incubated for 30 days. The soil aggregate stability increased significantly with barley before harvesting and rye at day 30 after cover crop residues incorporation. The cover crop plant growth did not influence the soil acid phosphatase activity (APA) before biomass harvesting. Instead, the cover crop residues increased the soil APA only for a short period. The negative correlation between soil aggregate stability and APA can be explained by the variability in soil moisture. While the low cover crop residue quantity might have not been sufficient to increase and maintain the microbial activity.","PeriodicalId":7094,"journal":{"name":"Acta Agriculturae Scandinavica, Section B — Soil & Plant Science","volume":"4 1","pages":"992 - 1005"},"PeriodicalIF":0.0,"publicationDate":"2021-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91488349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, the purpose of this study was to assess the effect of sowing rate and variety on the nutrient content of faba beans. Five varieties were tested: Bauska, Gloria, Julia, Jõgeva, and Lielplatones. Two sowing rates were used: 30 seeds m−2 (100%) and 36 seeds m−2 (120%). The higher sowing rate decreased the K content in varieties Gloria, Julia, and Lielplatones in 2016. In 2015 the higher sowing rate increased the Ca content while in 2016 the sowing rate decreased the Ca content. The higher sowing rate increased the Mg content in varieties Gloria and Jõgeva in 2016. The highest N, K, and Mg contents were found in variety Gloria. In 2015 the highest K content was found in varieties Gloria and Jõgeva, while in 2016 the highest K content was in variety Lielplatones. The highest Ca content was in variety Bauska. In conclusion, an increased sowing rate did not have a consistent effect on the nutrient content of faba beans. Thus, variety Gloria can be recommended for faba bean production in Northern Europe because it was the variety with the highest nutrient content.","PeriodicalId":7094,"journal":{"name":"Acta Agriculturae Scandinavica, Section B — Soil & Plant Science","volume":"41 1","pages":"466 - 471"},"PeriodicalIF":0.0,"publicationDate":"2021-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78122166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main aim of the study was to identify plant species that are less susceptible to powdery mildew for possible application as cover crop, in trap cropping or seed production. Powdery mildew assessments were conducted in two growing seasons that were characterised by unusually warm and dry conditions for northern temperate climatic conditions. In both growing seasons, a heavy powdery mildew infection (over 80%) was recorded on B. napus and B. nigra plants, indicating that E. cruciferarum is an important pathogen for oilseed crops in northern Baltics. However, three other cruciferous species S. alba, E. sativa and R. sativus showed full resistance to powdery mildew, and thus, even under strong powdery mildew pressure, they can be cultivated without pesticide application in northern Baltic conditions. We suggest that in changing climatic conditions powdery mildew is expected to become a more serious problem in cruciferous oilseed crops in northern Europe, especially under intensive short-rotation farming practices.","PeriodicalId":7094,"journal":{"name":"Acta Agriculturae Scandinavica, Section B — Soil & Plant Science","volume":"6 1","pages":"443 - 452"},"PeriodicalIF":0.0,"publicationDate":"2021-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74392100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, Illumina MiSeq high-throughput sequencing were used to explore the relationship between the incidence of Fusarium wilt of tomato and soil microorganisms in more detail and analyse the contributing factors of changes. Compared with the control treatment, vermicompost treatment promoted the growth of Actinobacteria, Chloroflexi, Saccharibacteria and Planctomycetes and inhibited the growth of Proteobacteria, Gemmatimonadetes, Firmicutes, Verrucomicrobia, and Cyanobacteria. The relative abundance of Ascomycota was negatively related to that of Basidiomycota. The results showed that the incidence of Fusarium wilt of vermicompost treatment was 36.5%∼73.9% lower than that of the control treatment. The relative abundance of Proteobacteria was positively related to the incidence of Fusarium wilt, while the ACE and Chao diversity indices of bacterial communities were significantly negatively related to the incidence of Fusarium wilt (p<0.05).
