CHANGES OF SOIL MOISTURE IN THE UNSATURATED ZONE DURING RAINLESS PERIODS IN THE MARTEW FOREST AREA

The paper presents changes of volumetric soil moisture during rainless periods in the area covered by the sixty year-old pine stand. The analysed area is located in the Tuczno Forest District, the Martew Forest Area in the north-western part of Poland. The calculations were based on the measurements of volumetric soil moisture at seven different depths below the ground level (to the depth of about 7 m). A set of probes was installed in the unsaturated zone for moisture measuring, using TDR method (Decagon Devices Em5b-ECH2O), in order to calculate volumetric soil moisture changes in the unsaturated zone. Volumetric soil moisture measurements used in this work were calculated at daily intervals during rainless periods in the years 2013-2016. The variability of volumetric soil moisture during the rainless periods was registered only at the shallowest level (0.85 m below the ground level). On deeper levels over relatively long (more than 20 days) rainless periods these changes are negligible. The Authors suggested the Weibull equation to describe the changes of volumetric soil moisture at shallow levels during the rainless periods. ...

ANALYSIS OF TREND CHANGES IN DEGREE-DAY VALUES OF HEATING AND COOLING: BROILER BREEDING CASE

An ideal broiler house should be designed to minimize the effects of weather changes and to keep indoor conditions at the comfort temperature of the animals. In this case, this should be done with minimum cost and possible lowest operating costs. Degree-day methods are used in order to have knowledge of the energy need of any structure. With this method, the measured values or meteorological data can be used to give information about the heating and cooling energy quantities of structures. Depending on the climate change in recent years, the changes need to be examined that have taken place in order to provide optimum comfort in animal barn. Isparta province and districts were selected as the study area. The long-term average daily temperature values are used from meteorological stations of the selected region. The heating and cooling degree day values were calculated for selected balance temperatures in broiler breeding. Linear Regression Analysis and Spearman Rank Correlation Test were conducted to determine the changes of these values due to climate change. In conclusion, it was determined that there were statistically significant trends at 5% significance level in Egirdir (21°C), Isparta (31-29-25 and 23°C), Kasimlar (18°C), Senirkent (31-29-25-23 and 21°C), Sutculer (all ...

Climatization, Greenhouses, Heat load, Lower Euphrates basin

As a result of the increase in the world population and the decrease in agricultural land, the need for food increases every day. Nowadays, breeding studies are carried out to increase the yield of plants to get more products from the same area. Furthermore, controlled production areas are created by optimizing climatic conditions and the continuity of production is ensured. It is called greenhouse, where production can be carried out throughout the year and the indoor temperature and humidity conditions can be controlled. Nowadays, greenhouses are now functioning as an industrial enterprise. However, greenhouses need to comply with the principles of quality production, efficient income growth and physical environmental protection. Almost all of the plant production in greenhouses in Turkey is done in the Mediterranean region, but in the Southeastern Anatolia Region, it is done in a very limited greenhouse area. The increase of protected agricultural areas in the Mediterranean region and the fact that the production volume cannot reach a certain limit makes it necessary to investigate alternative protected production areas. In this study, climate conditions of Antalya province and climate data of four provinces of the Lower Euphrates basin are compared with each other and statistically compared. As ...

THE EFFECTS OF WALNUT SHELL AND THYME STALK BIOCHAR ON PEPPER: PLANT PARAMETERS

The aim of this study is to determine the effects of biochar that obtained from walnut shell and thyme stalk on yield and biomass development of pepper plant. Biochar obtained by self-constructed oxygen-free reactor at 400 C. According to experimental design, 2 different biochar raw materials (walnut shell and thyme stalk) at 3 different doses (0, 0.1 and 0.2% w/w) were evaluated in either with or without sulphur application (0 and 0.1% w/w). Results revealed that the all parameters tested were greatly influenced from raw material, biochar dose as well as sulphur applications. Significant differences were determined between the raw materials in which the biochar was made. According to mean values the walnut shell biochar provide 38% more shoot dry weight than thyme stalk biochar. These findings clearly indicate that although biochar almost consisted of carbon, all of the biochar are not the same, and depends on the raw material; biochar even can reduce plant growth. The effect of sulfur application was also significant, especially in the pots where biochar and sulfur were applied together. The lowest yield value was determined at control as well as 0.1% thyme stalk biochar applied pots as 34.2 and 33.4 g pot-1, respectively while ...

THE DISTRIBUTION OF DEEP-LITTER TEMPERATURE IN A DAIRY BARN

The paper presents results of studies of some indoor microclimate parameters and temperature of litter bedding in a freestall barn used to house dairy cattle in a deep-litter bedding system. The studies were conducted in the period from 22 March 2014 to 22 March 2015. The analysis of distribution of litter surface temperature showed its strong relationship with indoor air temperature. In summer, temporary exceedances of the allowable indoor air temperature by even 12 °C were noted. The studies showed a significant effect of the number of animals in the barn on litter surface temperature. In the periods when cows stayed in the barn, two zones could be distinguished: the sidewall zone 1.5 m wide at the western outside wall of the building and the inner zone encompassing the remaining part of the barn. Differences in litter temperature between these zones, when cows stayed in the barn, reached 10°C. When the building was empty and animals were on pasture, the differences between litter surface temperatures were much smaller and did not exceed 3°C. ...

EFFECTS OF AGRICULTURAL DROUGHTS IN THE PROVINCE OF KUJAWSKO-POMORSKIE AND POSSIBILITIES OF MINIMIZING THEIR IMPACT

The aim of the research was an evaluation of the frequency and intensity of agricultural droughts and their effects in the province of Kujawsko-Pomorskie as well as to indicate ways of increasing productivity in such drought periods by applying irrigation. It was found that the drought periods around Bydgoszcz occurred in 17 vegetation seasons out of 30 analysed. They were differentiated by intensity and duration but were also characterized by high irregularity of their occurrence. In the past 30-year period, droughts were especially intensified in the years 1989-1995. In the years 2001-2005 droughts were rare (36%), as compared with the previous 15-year period of 1986-2000 (64%). Crop production of some selected agricultural cultivations in the province of Kujawsko-Pomorskie depended to a large extent on the degree of precipitation shortages in the periods of intensified water demand. The best correlations and determination coefficients exceeding 80% concerned maize cultivations. The occurrence of droughts, expressed by the degree of atmospheric precipitation shortages in June and July, led to a decrease in grain crops in the province by 13%, on average. In the extremely dry year of 2006, a decrease by 27%, in relation to average crops, was observed. Active methods of minimizing effects ...

EXPERIMENTAL EVALUATION OF THE ACCURACY PARAMETERS OF FORMER SURVEYING NETWORKS

Surveying field measurements performed during the development and updating of land registry were based directly on measuring networks. Accuracy parameters of these networks are lower in comparison with modern measurement networks. The main reasons for the lower accuracy relate mainly to the lower precision of measurements, two orders of network and approximate techniques for determining the coordinates of the points of these networks. Currently, archival materials of the State Geodetic and Cartographic Resource are used during surveying of real estate (division, separation, modernization of land registry). The paper presents the results of experimental evaluation of the accuracy parameters of former networks. The purpose of the performed evaluation to was to analyze the possibilities of use archival materials of the State Geodetic and Cartographic Resource during surveying works related to real estate. The study was carried out on the basis of three test objects located in the Małopolskie voivodship. Points of the analyzed networks found on the ground were measured (approx. 34% of all points), and then their coordinates were determined. The representative research sample was constituted by sets of deviations Z - the length of the displacement vector of the point in the research sample in relation to its position ...

CHANGES OF WATER POLLUTION DYNAMICS IN VISTULA RIVER ON WARSAW CITY AREA

The paper presents change of water quality within Vistula River in the city of Warsaw. Water samples for analysis were taken from four different measurement points in the period from February to June 2016. Based on the results of laboratory studies it was demonstrated that the Vistula River in Warsaw is exposed to the input of pollutants contributing to increase the salinity, especially in winter and early spring. The concentration of both chlorides and sulphates were highest in February and was decreasing in subsequent months of the year. At the same time it has been shown that during the entire study period the concentration of Cl- ion exceeded the limit values for water quality II class in Poland. While the SO42- concentrations in water samples taken in the winter months (February-March) exceeded the limit values for the second quality class, in April, it was within the acceptable range for II class water quality, and in May and June does not exceed the value referred to as standard for I class of water quality. Based on the analysis of indicators of nutrients (N-NH4, N-NO3, Ptot.) it was found that the Vistula is not exposed to eutrophication due to their low ...
