“…Цей тип забруднення потребує заходів щодо усунення токсичного впливу, насамперед для ведення екологічно безпечного сільського господарства. Важливу роль у біоремедіації ґрунтів відіграють мікроорганізми, які в складі консорціумів здатні демонструвати більшу метаболічну універсальність до складних забруднювачів [11].…”

In the modern world, biogas technology is gaining momentum as an ecological alternative to the production of biofertilizer after anaerobic fermentation of various types of waste. Due to the large amount of organic, nutrient and biologically active substances, biogas digestates are often applied directly to the soil as an organic fertilizer to improve soil quality and increase yield. The purpose of the article is to determine the ecological safety of the digestate obtained after anaerobic fermentation of chicken litter and sewage sludge, as part of a biocomposite for soil purification from heavy metals. The methodological basis of this study are experiments on the phytotoxicity of digestate samples based on the results of the germination of pepper seeds in Petri dishes using aqueous solutions of untreated digestate and digestate treated with phosphogypsum. The expediency of choosing a phosphogypsum treatment method was due not only to the possibility of reducing the presence of pathogens in digestates, but also to obtain a biocomposite capable of adsorbing harmful elements from the soil and feeding it with necessary substances. Using the germination index, the level of phytotoxicity of digestate based on various organic wastes was assessed, the effectiveness of the use of digestate as a biological fertilizer was substantiated. It was determined that digestate based on sewage sludge became an ecologically safe substrate for the germination of pepper seeds. Digestate from chicken litter treated with phosphogypsum on the 20th day of anaerobic fermentation showed a phytotoxic effect on pepper seeds. Indicators of the germination index increased on the 30th day of anaerobic fermentation, which indicates a decrease in the toxicity of the material after the end of the anaerobic fermentation process. In general, a germination index higher than 50% was observed in all samples of untreated digestate and a greater number of samples of treated digestate for both substrates. The article provides recommendations for evaluating the maturity of digestate using the seed germination index as a quick indicator for determining the phytotoxicity of substrates and, accordingly, the level of environmental safety of the material for soil and plants.

“…Soil Science deals with various environmental compartments including soil and water resources management [3]. Assessments and classification of soil properties (morphological, physical, biophysical, chemical, and hydraulic) help to understand the current status and condition of soil for sustainable agricultural development [4][5][6]. Soil is the reservoir and store house for nutrients, water, and moisture for plant growth, and also for biological, chemical, and thermal (heat) processes of rock weathering [7][8].…”

Information regarding the soil water relationship for irrigation under fadama management system is crucial. A field measurement study was undertaken to evaluate and classify the infiltration rates, infiltration capacity and hydrological soil group classes of fadama in the study area. Fifteen (15) different soil units were randomly selected based on the presence of agricultural activities and the nature of irrigation applications. The infiltration rates for all the soil units ranged between 2.4 cm/hr and 12 cm/hr, while the cumulative infiltrations ranged between 4.8 cm to 24 cm. Soil unit 8 recorded the highest infiltration rates of 12 cm/hr and cumulative infiltration of 24 cm, while soil unit 10 had the lowest infiltration of 2.4 cm/hr and cumulative infiltration of 4.8 cm. Soil infiltration capacity was classified as moderate and moderate-rapid. Soil units 7, 8, 9, 13, 14, and 15 required an overhead method for correct water economy and proper utilisation for plants whereas soil units 1, 2, 3, 4, 5, 6, 10, 11, and 12 ideally may require a surface irrigation method probably because of the moderate basic infiltration rate. The Hydrologic Soil Groups (HSGs) of the study sites were evaluated as A, B and C. Soil units 1, 2, 4, 7, 8, 11, 12, 14, and 15 fall under group A, and soil units 3, 5, 6, 10, and 13 fall under group B, while soil unit 9 falls under group C, corresponding to well-drained soil texture with low runoff potential, moderately well-drained coarse texture with moderate runoff potential and moderately fine texture with moderate to high runoff potential, respectively. It is suggested that water management under irrigation in the fadama sites of the study area depend largely on the nature and condition of the soil, and that sites with low runoff potential are likely to retain more water during the days compared to moderate and moderate-rapid.
