However, little is known about how organically managed hybridised perennial wheat (Triticum aestivum L. × Thinopyrum spp.) stimulates SOC, microbial biomass and activity in marginal soils. Therefore, the effect of three organically managed cropping systems: i) sole perennial wheat; ii) perennial wheat with clover intercrop; and iii) annual wheat; were investigated at three sites in Germany on marginal soils with different textures (silt loam (SL) with impervious soil layer, clay loam (CL) with 30–35% stone content and sandy soil (SS) with low nutrient content). Soil samples, from each cropping system and site, were taken from A- and B-horizons after 3 years of cultivation and were evaluated for SOC, microbial biomass C and N (MBC, MBN), basal respiration, and C-enzyme activities. In CL and SS soils, perennial wheat with clover intercrop increased SOC in the A-horizon compared with annual wheat and sole perennial wheat. Varied effects were observed in the B-horizon, with sole perennial wheat in CL having higher SOC and MBC than the other two cropping systems. SOC storage stock in the B-horizon of perennial wheat was on average 18% higher relative to annual wheat, revealing a considerable C storage potential. Overall, the study showed that perennial wheat cultivation can improve microbial biomass and activity in marginal soils compared with cultivation of annual wheat.","PeriodicalId":8904,"journal":{"name":"Biological Agriculture & Horticulture","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49329364","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 experimental treatments included harvest of tomatoes in two seasons, three maturity stages, three transportation conditions (varying distances and road surface profiles), four disinfection treatments (control, hot water, chlorinated or anolyte water in combination with biocontrol) and two storage conditions (cold (11°C) and ambient). For fruit harvested in winter, treatment with hot water (also for summer harvest) or with anolyte water + biocontrol and storage in cold conditions resulted in the highest concentrations of ascorbic acid (AA) compared with the other treatments. Fruit transported along the shorter and relatively smoother roads maintained higher AA (summer harvest) and lycopene concentrations compared with fruit transported the longest distance with moderately rough surface profile. The harvesting season and the disinfection treatments had significant effects on the concentrations of sugars. The nutrient characteristics of the tomatoes in the supply chain were shown to be affected not only by environmental and postharvest practices, but also by the road quality, demonstrated for the first time in this study. Cold storage of tomatoes, disinfection with hot water or anolyte water + biocontrol, and transportation planning to minimise the use of rough road surfaces and to use the shortest distances to markets, were recommended as best practices for the industry. Options for improvement of fruit packaging to provide adequate cushioning against physical damage during transportation should be investigated.","PeriodicalId":8904,"journal":{"name":"Biological Agriculture & Horticulture","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43569482","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}

Aqueous extracts used in organic agriculture, such as compost – or vermicompost-tea, often have deficiencies in macro-nutrients and ionic imbalances. However, when organic materials are used as fertilisers, they are often applied in combination with plant growth promoting bacteria (PGPB), which can improve the availability of the nutrients. In this study, PGPB were used as a tool to facilitate the nutrition of horticultural crops without using synthetic fertilisers. Three bacterial species (Azotobacter vinelandii (AV), Bacillus megaterium (BM) and Frateuria aurantia (FA)) were tested as (i) inoculated to an aqueous vermicompost extract and (ii) applied directly by fertigation to the growing medium in two tomato production cycles. The results showed that it was possible to obtain a balanced nutrient solution, with adequate concentrations of the main nutrient ions, from an aqueous and aerated solution made from vermicompost, without the addition of PGPB. In the second trial, the inoculation with PGPB to the growing substrate for tomatoes fertigated with vermicompost tea, resulted in significant increases in the yield and quality of the tomato fruit, increased nutrient assimilation by the plants and increased enzymatic activity in the growing substrate.","PeriodicalId":8904,"journal":{"name":"Biological Agriculture & Horticulture","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43696161","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}

Two commercial organic fertilisers, Fertor and Siforga, were applied at four rates (0.5, 1.0, 1.5, and 2.0 t ha−1), and shading was applied with two types of green polyethylene shading nets, retaining 30% and 50% of sunlight, respectively. Among the pomological characteristics, the clearest difference was observed for the number of clusters, which, in the second year, was significantly increased by both factors. The number of clusters was shown to have the highest correlation with the yield of berries. In the first year, only the higher rates of fertilisation affected the yields, but in the second year, the yields were significantly increased by all of the fertiliser treatments, compared with the control. For metabolic parameters such as dry matter, soluble solids, titratable acidity, sugars and ascorbic acid, the effects of the treatments were inconsistent. Only the highest rates of the fertilisers and the dark net had significant positive effects on the total phenolics. The concentrations of hyperoside in fruit from the shaded shrubs were significantly higher than in the control, with a similar pattern also for isoquercetin, but only for the dark net.

However, cornflower produces nectar that is a resource for pollinators and crop pest predators and parasitoids. To gain benefit from this resource, it is necessary to manage the presence of cornflowers and to maintain the population at a balance that ensures the beneficial ecosystem services whilst avoiding competition with the arable crops. This paper describes bispecific competition trials between cornflower and winter wheat in small experimental plots. The annual experimental conditions were highly variable, leading to plant densities that were too high or too low to estimate a competition threshold. The results provided relevant information on intraspecific competition among cornflower plants and its effect on the growth, the biomass and the yield of wheat. Conventional and organic farming could gain from growing some weeds like cornflower in the fields to provide ecosystem services for the crops.","PeriodicalId":8904,"journal":{"name":"Biological Agriculture & Horticulture","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2021-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44812537","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}

Soil nitrogen and phosphorus concentrations and organic decomposition rates were highest when pigs were present, consistent with recent inputs of feed and nutrient redistributed in dung and urine. Soil nitrogen and phosphorus concentrations and organic decomposition rates declined over the subsequent courses. The overall production system was sustained by inputs of pig feed one year in four, with nutrients being carried over to subsequent years. The pigs caused significant physical damage leading to soil disaggregation, but the soil structure recovered over the following 2 years. The high concentrations of inorganic nitrogen, particularly nitrate at high concentration ‘hot-spots’ around feeders and housings, and the poor soil structure caused by the pigs represented a significant risk of loss of nutrients and soil.

It took 15, 12 and 9 months for decomposition of 90% of the litter of H. binata, P. cineraria and T. undulata, respectively. Regression analysis showed that rainfall and air temperature had significant impacts on the decomposition process. Soil moisture and soil microbial biomass carbon showed high correlations (R2 > 0.70, p < 0.01) with litter decay. The rate of release of N (k N = 0.0014, surface (0–15 cm); k N = 0.0015, sub-surface (15–30 cm)) and K (k K = 0.0041, surface; k K = 0.0047, sub-surface) was highest from P. cineraria, whereas release rates of P were statistically equivalent for all species. N release from the decomposing litter increased initially, but then decreased as decomposition progressed. Concentrations of P, K and Mg in the litter decreased throughout the decomposition, with some fluctuations in P and Mg for P. cineraria and H. binata at the later stage.
