We examined if cover crop and addition of organic materials may counteract these effects. Organic materials were one application of biochar mixed with liquid digestate (BLD); solid digestate (SD); or farmyard manure (FYM); with or without winter rye as cover crop, in a field with regular potato growing. Organic amendment increased SOM, especially for FYM and BLD, while cover crop did not affect SOM. Yet, cover crop increased tuber yields in the second year, and reduced the severity of potato diseases by 10% in post-harvest potatoes in both years. In the second year, the number of marketable potatoes after storage increased by 37% with cover crop. Organic amendments did not affect potato yield or quality, but the proportion of marketable potatoes tended to be higher in the amended soil. By lab incubation, BLD showed the largest potential for SOM storage, up to 32 years, followed by FYM and SD. Cover crops and organic amendments is recommended in potato production, especially for early potatoes where there is sufficient time after harvest to establish a good cover crop.","PeriodicalId":40817,"journal":{"name":"Acta Agriculturae Scandinavica Section B-Soil and Plant Science","volume":"74 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83995857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nitrogen retention capacity and loss of ammonia volatilisation, leaching, etc. of paddy soil with large differences in nitrogen levels from two long-term rotations, garlic-rice and wheat-rice, were measured using the soil column simulation method. The results showed that the loss rate of leaching was only 5.4%, whereas that of ammonia volatilisation was up to 22.8%, which was the main nitrogen loss way of paddy soil under the two rotations. The average ammonia volatilisation rates under wheat-rice rotation with high and low nitrogen application rates were 12.1% and 40.2% higher than that under garlic-rice rotation, leading to a decrease in the total nitrogen loss amount and rate through ammonia volatilisation by 29.8% and 8.8%, respectively. As a result, nitrogen retention in the soil under garlic-rice rotation increased by 12.7%. In conclusion, the long-term garlic-rice rotation could significantly inhibit ammonia volatilisation, thus improving the soil nitrogen retention capacity. The straw return may increase soil organic matter content, reduce ammonia volatilisation loss, and enhance soil nitrogen retention capacity and productivity.","PeriodicalId":40817,"journal":{"name":"Acta Agriculturae Scandinavica Section B-Soil and Plant Science","volume":"57 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74169012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, the study aimed to assess the presence of soil microorganisms in lahar-laden soils in Sta. Rita, Pampanga, with their ability as beneficial microbes for crop production. Vigna radiata was used as the trap crop and grown for a maximum of 35 days in a microcosm experiment where all variables were similar except for the location of the sampling site. Through the sequence analysis of the 16S rRNA gene, five representative isolates revealed close resemblance to the genus Bradyrhizobium and Rhizobium, while the others were classified as non-rhizobial endophytes, namely, Pseudomonas, Agrobacterium, and Leifsonia. These results indicate that the lahar-laden soils in the sampling site harbour some agronomically-important genera of microorganisms. Surprisingly, this is the first time that the species Leifsonia xyli was identified and isolated in acidic lahar-laden soil. In contrast, it is hypothesised that the presence of L.xyli in this study might be attributed to the acidic soil pH, leading to the suppression of rhizobia in root nodules.","PeriodicalId":40817,"journal":{"name":"Acta Agriculturae Scandinavica Section B-Soil and Plant Science","volume":"298 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79640828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results showed that after eight weeks, the RR C O 2 of sprouted control onions was 52% higher than that of unsprouted control onions. High concentrations of soluble sugars (glucose, fructose and sucrose) were observed for cold treated bulbs (from 9 to 20 mg g - 1 FW) after two weeks following cooling, but in control bulbs high concentrations were only observed after eight weeks. In cold-treated onions, a slight increase in phenolics (from 0.17 to 0.2 mg g - 1 FW) was observed after one week, and then there was a decrease to 0.12 mg g - 1 FW after five weeks. In inner buds of control bulbs, an increase from 0.17 to 0.2 mg g - 1 FW was observed during the first five weeks and then a decrease to 0.15 mg occurred during the three last weeks when the bulbs began to sprout. Peroxidase activity followed the same pattern as phenolics, with a decrease (38%) in cold-treated bulb after four weeks. In control samples, a decrease of 25% was noted after eight weeks. This decrease in POD activity coincided with the decrease in phenolics and the onset of sprouting. With cold treatment, total sprouting was observed after eight weeks. In comparison, only 20% of the control bulbs started sprouting after the same period.","PeriodicalId":40817,"journal":{"name":"Acta Agriculturae Scandinavica Section B-Soil and Plant Science","volume":"34 1","pages":"16-20"},"PeriodicalIF":1.6,"publicationDate":"2003-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76470091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
