Avoiding high-temperature stress effectively can ensure sufficient plant production in hot seasons. Therefore, we proposed the use of zone cooling to decrease the temperatures around the chrysanthemum canopy using a heat pump and duct at the bottom (base cooling), top (top cooling), and above (above-top cooling) the canopy. The spatiotemporal distribution of temperatures (air, leaf, and stem temperatures) was measured under the various zone cooling treatments applied, and compared with those under the treatments which were not subjected to cooling (no cooling) and were entirely cooled (entire cooling). The air temperature around the targeted cooling regions and some plant temperatures declined substantially under the base and top cooling treatments at night, but such a decline was not observed with the above-top cooling treatment. During the day, the cooled region under top cooling was directly affected by solar radiation, but this region was unaffected under the base cooling treatment. The cold air was maintained at the bottom. The results indicate that solar radiation substantially influenced spatiotemporal tem - perature distribution. Moreover, base cooling was found to be the most effective method during both day and night. Thus, this study examines the spatiotemporal temperature distribution under zone cooling methods in the chrysanthemum canopy, thereby advanc-ing our understanding of the fundamental knowledge required for the establishment of a practical zone cooling system.","PeriodicalId":13959,"journal":{"name":"International Agrophysics","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2023-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42858514","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 aim of this study was to evaluate the effect of thea digestate which originated fromon a widely cul - tivated perennial crop ( Miscanthus giganteus ). Cchanges in the physicochemical properties of the soil, the abundance of soil microorganisms, and soil respiration were all assessed. Three types of digestate: fresh in the liquid form, processed – dried and pyrolysed, were tested and compared with mineral fertilization and an unfertilized control. Soil samples were taken in spring 2014, summer 2015 and autumn 2016. In total, 14 variables were analysed: total carbon, hot water extractable carbon, total nitrogen, C/N ratio, phosphorus, magnesium, potassium, pH, bacteria, fungi, O 2 intake, CO 2 emission, total carbon mineralized after 7- and 100-day-long respiration. Overall, regardless of the form of the digestate, the chemical parameters of the soil improved, although the extent of the improvement depended on the applied form of the digestate. The highest TC 12.79, N 1.29, K 257.95 and P 149.96 g kg –1 DM were determined in the plots fertilized with biochar. All digestate forms had a positive influence on the bacte - rial DNA abundance, and biochar also affected the abundance of the fungal DNA and the potential carbon sequestration in the soil. Pyrolysed digestate may have a particular value in the fertilization of perennial industrial crops.","PeriodicalId":13959,"journal":{"name":"International Agrophysics","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42898535","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}

At present, the use of by-products from plant food production is gaining more interest because these products contain a large amount of valuable nutritional compounds e.g. dietary fibre, proteins, polyphenols, unsaturated fatty acids, vitamins. The by-products improve both the nutritional profile and the health-promoting properties of bakery products but simultaneously impair some technological properties, which is strongly related to the structure of the gluten network. FT-IR spectroscopy was used to determine changes in the gluten structure through the addition of by-products from the vegetable industry and cold oil pressing production. The supplements were added to the common wheat dough in the amounts of 3, 6, 9 and 12%. Analysis of the spectra indicates that changes in the gluten structure and the distribution of water populations are connected with the type of technological process from which the supplement originated and hence its chemical composition. Vegetable supplements cause the formation of aggregated structures such as pseudo-β-sheets, whereas gluten samples modified by oil supplements contain mainly basic secondary structures i.e. α-helices, β-turns and antiparallel-β-sheets. With regard to the water populations, oil supplements do not affect them or affect them slightly. Vegetable supplements lead to the formation of a weaker gluten network. This is observed in the form of a decrease in the number of strong hydrogen bonds","PeriodicalId":13959,"journal":{"name":"International Agrophysics","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2023-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49357569","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}

Das","doi":"10.31545/intagr/156829","DOIUrl":"https://doi.org/10.31545/intagr/156829","url":null,"abstract":". Field water balance and root water uptake in wheat were simulated with Hydrus-2D after a 7-year transition to conservation agriculture. The zero-tilled system with a 40% anchored residue improved soil structure and porosity. Water retention was augmented for most of the growing period, especially in the subsurface (15-30 cm), which was essentially a compact layer (penetration resistance >2 500 kPa). The lower soil strength allowed the roots to extend further as compared to conventional tillage. The loss in drainage was reduced by 54-74% over the season using zero tillage with residue. Improved initial crop establishment led to a higher leaf area index and also to an enhanced interception of photosynthetically active radiation. Soil evaporation was also reduced, and root water uptake was 14-17% higher in zero tillage with residue. The grain yield was 17% higher in zero tillage with residue with a marginally higher crop water uptake efficiency. The adoption of conservation agriculture opti - mized water uptake in wheat by the improving physical condition of the soil and plant water availability. Hydrus-2D was used to successfully simulate the soil water balance and root water uptake in wheat under conservation agriculture. Conservation agriculture requires a redesign of irrigation scheduling, unlike in conventional practice. The simulation of water balance in the soil will aid in irrigation water management in the wheat crop in order to achieve a higher degree of efficiency under conservation agriculture.","PeriodicalId":13959,"journal":{"name":"International Agrophysics","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2023-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46751531","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 purpose of this work was to determine the effects of lowering nitrogen fertilization on the baking value of winter wheat cultivars and it also serves as a response to the implementation of the Nitrates Directive. Nine wheat cultivars were tested, which represented four technological groups that are included in the Polish National List of Agricultural Plant Varieties. The wheat was cultivated over a period of two seasons as a two-factor field experiment designed to utilize the method of randomized blocks, in four replicates. Two distinct applications of nitrogen fertilizer were adopted in the experiment: 120 and 200 kg ha -1 N. The Zeleny index, the quantity of protein and gluten, and the alveograph characteristics were determined in order to assess the baking value of t he wheat. Lowering the level of nitrogen fertilization to 120 kg ha -1 N caused a negative effect on the quality of the wheat, with regard to a lower Zeleny index, protein and gluten quantity. The alveograph parameters were affected by wheat cultivars while the nitrogen dose applied and the crop year had no effect. Lowering the degree of nitrogen fertilization of wheat crops to comply with the Nitrates Directive implementation may cause the production of wheat with a lower protein quantity which is a crucial parameter in grain trading. However, the reduction in nitrogen fertilization causes only a slight, statistical non-significant reduction in the alveograph characteristics of wheat flour dough","PeriodicalId":13959,"journal":{"name":"International Agrophysics","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2023-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44810681","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 aggregate stability of the soil is subject to the influence of anthropogenic factors and is of great interest all over the world. The research aimed to quantify the correlations between soil organic carbon, total nitrogen, total phosphorus, and total potassium, soil macropore parameters and water-stable aggregates under no-tillage and conventional tillage in Cambisol. The content of water-stable aggregates and macroporosity tended to increase in the following order: conventional tillage (returned residues) < conventional tillage (removed residues) < no-tillage (removed residues) < no-tillage (returned residues) in both fertilizations. The relationships between total nitrogen and various soil factors were investigated: soil organic carbon (r = 0.65, p < 0.05), total phosphorus (r = 0.65, p < 0.05), were statistically significant. Soil organic carbon and total nitrogen were positively correlated with water-stable aggregates (r = 0.81, p < 0.01 and r = 0.68, p < 0.05, respectively), whereas the relationship between total potassium and water-stable aggregates was negative. The relationship between total phosphorus and water-stable aggregates (r = 0.62, p < 0.05) was positive. The soil chemical properties, macropores and water-stable aggregates that were averaged across the residues and fertilizations were higher in no-tillage than in conventional tillage. Soil organic carbon, total nitrogen and total phosphorus all had a positive direct influence on the formation of water-stable aggregates under different tillage conditions. Since our results are largely based on correlations, the mechanisms of interaction between the soil chemical properties, water-stable aggregates and the formation of pores in the soil need to be explored further in future investigations.","PeriodicalId":13959,"journal":{"name":"International Agrophysics","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2023-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45123897","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}
