Evaluation of Sprayed with Ozonated Water Spring Barley (Hordeum vulgare L.) Grain Quality by Chemical and Holistic Methods

Paper Id: 85 [Abstract]

<p>Research objects used herein are chemical and holistic test methods for spring barley and ozonated grain. The aim of this research project is to (1) analyze the influence of ozone-saturated water spray on chemical and electrochemical parameters of spring barley grain, (2) determine the electrochemical characteristics of barley grain grown by spraying with ozone and water by seasonality, (3) evaluate the electrochemical parameters of barley grain according to the applied technologies, and (4) analyze the possibilities of applying the method of biocrystallization for the quality of spring barley grain. Methods used include identification of chemical and electrochemical parameters, biocrystallization, and analysis of numerical values of independent evaluators. After the evaluation of spring barley cultivated using ozone-sprayed water, no statistically reliable effect of ozonated water on grain quality was established. Spraying with more water (plain and ozonized) shows a downward trend in numerical values of absolute redox potential. The lowest energy P numerical values were calculated for barley grain, which was sprayed with water 4 times. Biocrystallization method for barley grain quality requires further preparation of the methodology.</p>

THE INFLUENCE OF AGRICULTURE ACTIVITY ON SURFACE WATER STATUS IN LITHUANIA

Paper Id: 36 [Abstract]

It is the opinion of many authors that one of the most important and essential sources of diffuse river contamination is improper farming [1-3] Riversides are a strategically advantageous location for agricultural activities since river floodplains are exceptionally fertile. However, the diffuse contamination from farms is caused by not only the riverbank activities but also the intensive farming throughout the river basin. In pursuit of a larger yield, farmers intensively use manure, various chemical fertilizers and pesticides. However, these materials are easily washed out from the soil by rainwater, which then contaminate rivers with the groundwater or surface runoff wastewater. It has been determined that approximately 30-35% of nitrogen and 10-15% of phosphorus, two main contaminates of the surface waters, originate from agricultural activities [4]. The aim of this research was to evaluate the influence of agricultural activities on the state of surface water in Lithuania. Based on the studies conducted in 2014-2019, only 20 % of the studied lakes (total of 40 lakes studied) do not meet the criteria for good ecological status (0.100–0.140 mg/l) according to the phosphorus (Pb) concentration in water. At lakes Latežeris and Luksnėnai the concentration of Pb indicated a bad ecological class (0.231–0.470 mg/l), while at lakes Draudeniai, Paežeriai and Mastis these indicated very bad class (0.231–0.470 mg/l). The lake Talkša and in ponds Bubliai and Stepanioniai were in average ecological class (0.141–0.230 mg/l). The load of biogenic material in the Lakes basins was calculated using SWAT model data. It has been determined that the largest amounts of nitrogen and phosphorus in the Lakes basin appear due to agricultural activities.
