Some practices such as fertilisation and pesticide use are carried out in order to obtain high yields in agricultural production. However, as a result of these practices, agricultural pollutants may occur as a result of incorrect agricultural practices. Problems such as water pollution, air pollution, soil pollution, nutrient imbalance, salination in soils, eutrophication in waters, beneficial microorganisms in soils and damage to human and animal health occur due to faulty fertilisation and pesticide applications, misuse of agricultural soils, and inaccuracies in the disposal of plastic wastes. In this study, the literature on agricultural polluting factors was examined and it was aimed to raise awareness about agricultural pollution by explaining the harms of agricultural polluting factors to the environment and the health of living beings and by trying to offer solutions. Within the scope of this targeted awareness, this study; It is aimed to raise the awareness of producers in future production processes and to provide a stepping stone for scientific studies on this subject.

Ensuring the homogeneity of the indoor climate throughout the greenhouse is very important for uniform plant cultivation. In the study carried out to determine the indoor climate distribution in the heated greenhouse in the terrestrial climate, indoor temperature, relative humidity, dew point and vapour pressure deficit values were measured from 8 different measurement points. The distribution pattern of the measurement points was made horizontally and vertically at 2, 4 and 6 meters. Sensor placements are grouped vertically at 2 meters (G1: S1, S2 S3), at 4 meters (G2: S4, S5, S6) and at 6 meters (G3: S7, S8). Measurements taken during the day are divided into three parts. The climatic changes in the greenhouse were monitored as daily (00:00-23:30), daytime (08:30-17:30) and night (18:00-08:00) hours. According to the results obtained from the research, it was determined that the indoor climate parameters in the greenhouse change during the average daily, daytime and night hours at different times of the day and at different locations. According to this, it has been determined that it is important for better regulation of the greenhouse climate by monitoring the changes in the plant level as it rises from the greenhouse floor to the ridge with multiple sensors instead of a single sensor.

The rapidly changing quality of irrigation water requires urgent attention to understand and predict the long-term effects on soils and food crops, especially in a situation of global freshwater scarcity. The aim of the research was to assess changes in water quality in two selected lakes located in Poland in 2009–2016. The study was carried out in terms of the possibility of using selected reservoirs as sources of water for sprinkler irrigation of agricultural crops. The presented analysis was compared with a similar one carried out in 1999–2006 and 2004–2009 to determine the historic and present water quality state. Results indicate, that the source of pollution of the lakes is most often outflows from sewerage systems, the precipitation and surface runoff from the catchment areas of these lakes, which are mainly used as agricultural land. In Lake Niepruszewskie, the oxygen conditions, water transparency, phosphorus content, sestone dry matter and coliform titre increased, while the biological oxygen demand (BOD5), nitrogen, and chlorophyll content decreased. According to present research, in the Strykowskie Lake, the phosphorus content and BOD5 decreased, while the sanitary condition, nitrogen content and oxygen conditions deteriorated. The reduction of mineral fertilization in recent years has reduced the degradation of the lakes and allowed the water quality to remain in Class III of purity. Despite the visible improvement in the general condition of both studied lakes, constant monitoring of their quality is necessary, which is obligatory for the water from these reservoirs to be used for sprinkler irrigation of crops.

The goal of this study is to determine the crop water stress index (CWSI) and irrigation scheduling based on CWSI values, as well as to examine the correlations between CWSI, physiological parameters and grain yield of hybrid corn P31A34 in semi-arid climate conditions. In 2014 and 2015, the upper limit (UL) temperatures at which plants were entirely exposed to water stress were 1.178°C and 2.38°C, respectively. When the corn grain yield began to decline, the CWSI threshold value was 0.34, indicating the yield limit. Grain yield, crop water consumption, crop water stress index, chlorophyll content, water use efficiency and leaf area index were found to have negative correlations (p ≤ 0.01) with CWSI values in both years of the study. The findings revealed that in semi-arid climate conditions, a maximum of 30% water deficit could be used during the growing period of the corn compared to full irrigation (I100) for water savings and that a water deficit greater than 30% results in considerable grain yield losses. In areas with limited water resources, the moderate water deficit (I70) may be a viable alternative to the I100.

Promieniowanie jonizujące powoduje jonizację i/lub wzbudzenie atomów ośrodka materialnego, z którym oddziałuje. W zależności od mechanizmu oddziaływania mówimy o bezpośrednim i pośrednim promieniowaniu jonizującym. Pierwsza grupa obejmuje cząstki naładowane elektrycznie (alfa, beta, protony), które jonizują głównie na drodze oddziaływań kulombowskich. Z drugiej strony, cząstki obojętne (np. neutrony) i wysokoenergetyczne promieniowanie elektromagnetyczne (promienie X i γ) oddziałują z materią pośrednio poprzez efekt fotoelektryczny, rozpraszanie Comptona i tworzenie par elektron-pozyton, a także poprzez reakcje jądrowe. W pracy przedstawiono wynik eksperymentu, w którym nasiona Pieprzycy siewnej (Lepidium sativum L.) poddano działaniu promieniowania neutronowego. W eksperymencie wykorzystano komercyjne źródło Cf-252 (aktywność źródła w dniu eksperymentu A 11 MBq, wydatek neutronów W = 1,34E + 6 n/s,) [5-7]. Czas ekspozycji wahał się od 5 sekund do 11 godzin.

Lonizing radiation causes ionization and / or excitation of atoms of the material medium with which it interacts. Depending on the mechanism of interaction, we speak of direct and indirect ionizing radiation. The first group includes electrically charged particles (alpha, beta, protons), which ionize mainly by Coulomb interactions. On the other hand, neutral particles (e.g. neutrons) and high-energy electromagnetic radiation (X and γ rays) interact with matter indirectly through the photoelectric effect, Compton scattering, electron-positron pair production, and also by nuclear reactions. The paper presents the result of an experiment in which seeds Lepidium sativum L. were exposed to neutron radiation. A commercial Cf-252 neutron source was used in the experiment (source activity on the day of the experiment A = 11 MBq, yield of neutron source W = 1.34E + 6 n/s,) [5-7]. The exposure time ranged from 5 seconds to 11 hours.

With the increasing need for energy, energy studies to be obtained from waste gain importance. In this study, it has been tried to determine the amount of biogas energy that can be obtained from olive pomace (pirina), which is produced by processing oil olives. Numerical maps of pirina amounts and potential biogas energy values and location maps of the proposed pirina processing plant were created. The necessary calculations were made by comparing the obtained results with the relevant literature information. In the study, the current potential biogas energy amount was calculated, maps were created and the electricity and gasoline energy equivalent levels of this energy were tried to be calculated using the 2015-2019 data of the Mediterranean, Aegean and Marmara Regions. The total potential amount of pirina in the research area is 1853375.7 tons and the potential biogas energy amount that can be obtained is 33360762.4 MJ. Pirina, which is the production waste after pressing the olives for oil, can be used for energy production. By using pirina to obtain biogas energy, both the utilization of pirina and the development of the regions will be provided.
