“…Nitrates already exist in groundwater and will be present there for many years because of their 25-year half-life (Follett et al, 1991;Rubin et al, 1998). Given the nonpoint/diffuse nature of such contamination, there are no known means of extracting and treating all water from aquifers prior to human and animal use, and the use and production of nitrogenous compounds in agriculture and society is unavoidable.…”

“…Gaining insight into water distribution in soils is especially important for nutrient and contaminant distribution, which is of interest for agricultural applications and in relation to aquifer contamination [27]. Any substance entering the soil pore system interacts with the solid surface and, therefore, depends on solution distribution and interaction with the matrix.…”

“…This changes the solid surface and, hence, the pore system itself. Model calculations are often inadequate in describing water uptake into and the interaction of water with the soil matrix [27,28]. NMR relaxometry, therefore, offers a great potential for investigating soil water interactions without the need for modelling or sample destruction.…”

Proton NMR relaxometry is a very powerful tool for investigating porous media and their interaction with water or other liquids and the mobility and interaction of organic molecules in solution. It is commonly used in material science or earth science. However, it is only scarcely applied in soil science although it shows great potential for helping to understand water uptake into the soil matrix and processes occurring at the solid-liquid interface at soil particle surfaces. This review introduces proton NMR relaxometry in the context of soil science and discusses the most important applications of the method in this field. Relevant results from different applications of NMR relaxometry in soils are described and research gaps identified. Some original data is presented concerning biofilm formation in soils, which was investigated using proton NMR relaxometry. NMR relaxometry is a sensitive, informative and promising method to study pore size distribution in soils as well as many kinds of soil physicochemical processes, among which are wetting, swelling or changes in macromolecular status. It is further a very helpful method to study interactions between molecules in soil organic matter and can serve to study the state of binding of water or organic chemicals to soil organic matter. Relaxation times determined by NMR relaxometry are sensitive to various factors that play a role in soil-water interaction which is both an advantage and shortcoming of the method: NMR relaxometry can be applied to numerous investigations in soil science, but at the same time interpretation of the results may be very difficult in such complex and heterogeneous systems like soils.

“…As occurs to the diesel fuel, the commercialization of biodiesel or the biodiesel/diesel blend on the market of many countries can cause environmental damages due to spills. The danger associated with ecological threat caused by the infiltration of biodiesel or biodiesel/diesel blends into environment media like soil and ground water during its extraction, transportation, processing and distribution of the fuels [9]. The long term effects of genotoxic compound in contaminated soil can adversely defects the health of many living organisms including human beings, by exposing them through diverse pathways, such as ingestion of plants that uptake soil pollutants and also leaching of compound from contaminated soil to ground and surface water used as drinking water [10].…”

Abstract. The commercialization of biodieselldiesel blends on the market can cause environmental damages due to spills. This study aims to investigate the effectiveness of Pseudomonas putida as oil-biodegradable agent in soil contaminated with biodieseVdiesel blend (B20). The eflkctiveness on bioremediation have been conducted by examined several physico-chemical tests on biodieselldiesel-contaminated soil before and after seeding of P. putida. The spillage stimulation of B20 was conducted at laboratory scale for 24 days of incubation time. The results show that the bioremediation treatment able to remove up to 82%, 77%, 1676, and 10% of nitrogen, phosphate, sulfate and total organic carbon, respectively. The pH of soil sample was changed from pH 7.45 (Day 0) to 7.25 (Day 24) after the treatment. Meanwhile, the moisture content in the sample has increased from 44.11% (Day 0) to 50.35% (Day 24). All of these results show the good indication of quality improvement of polluted soil after treated with P. putida. It is apparent from the acquired results that the application of P. putih is suitable as effective microorganism and potentially exploits as useful oil-soil biodegradable agent in polluted soil.
