Özet
Many minerals such as especially nitrogen leaching out from the soil in exceed precipitation leach. This situation is a very important factor causing economic losses and environmental pollution. The aim of the study is to determine amount of the nitrogen leaching from the soil by precipitation outside the irrigation season from a weighing lysimeter controlled by a programmable logic controller (PLC). The research was carried out under Kahramanmaraş conditions in the five-month period between December 2018 - April 2019. In the study, a weighed lysimeter with a diameter of 113 cm (1 m2) and a depth of 130 cm was used and on which three-year-old (Maraş 18) walnut was planted. Two pluviometers were used to measure the amount of precipitation falling on lysimeter and the drained water from it. At the beginning of the experiment, 300 gr DAP (diammonium phosphate) fertilizer was applied to the lysimeter soil. A PLC automation system has been created that controls lysimeter and pluviometers for the research. The PLC automation system measured a total precipitation of 868.1 mm and drainage water of 686.6 mm Nitrogen concentrations and loads in the drainage water were determined from 26 water samples taken in the experimental period. In analysis of water samples, it was determined that nitrogen of 12.7 kg was leached from the soil of one hectare with the effect of precipitation. The leaching amount of nitrogen was 8.4%, of which 24% was in the form of ammonium (NH4) and 76% in the form of nitrate (NO3). The highest nitrogen leached with 5.4 kg per hectare in December, when the precipitation was the highest (264.1 mm). According to the results, as amount of precipitation increased, the leaching amount of nitrogen increased leach. Therefore, application programs of nitrogen fertilizer should be prepared by taking into consideration the precipitation regime of the region. It is very important for economy, the environment and human health. , . E-mail: sgencoglan@ksu.edu.tr OrcID:
