SOIL PROPERTIES IN MULTIFUNCTIONAL CROPS

Abstract

This paper examines the influence of multifunctional crops on soil properties. The research was conducted in a long-term stationary field experiment, which is located at the Experimental Station of the Vytautas Magnus University Agricultural Academy. The research was conducted in 2021. The purpose of the study is to compare the soil O₂ and CO₂ emissions in monocot, dicot and tricot crops. Cultivated crops are sown - beans (Vicia faba L), hemp (Cannabis sativa L.), corn (Zea mays L.). The fields were sown with mono, binary and ternary crops. Measurement of the experiment, the following devices were used for the research: "Screenalyt Honold Umweltmesstechnik" and electronic "Delta T device HH2" hygrometer with "WET" sensor. As a result of the research, it was found that at the beginning of the growing season, the highest concentration of CO₂ and O₂ in the soil was found in corn fields. In the middle vegetative season, the soil temperature increased and the accumulated concentration of CO₂ in the soil decreased, but O₂ increased to 23%. At the end of vegetative season, the soil temperature was higher in the fields where corn and beans were growing.

Key words: Multifunctional crops, bean, corn, hemp.
