INFLUENCE OF COATED UREA APPLICATION ON SOIL ORGANIC CARBON SEQUESTRATION
Abstract
The application of nitrogen fertilizers in the form of urea tends to increase acidity, especially on low pH soils, and as a result can lead to increased aluminum toxicity, which can adversely affect not only soil properties such as microbial activity, but also productivity. Application of different types of urea with inhibitors to reduce nitrogen losses would result in a different carbon response to fertilizers applications for the same soil type because of differences in soil micro-environment, including microbial biomass and activity. The aim of the study was to determine the influence of applying different forms of urea on the content of total nitrogen, organic carbon, phosphorus and assimilable potassium. The experiment was set up in the Western Plain of Banat, on soil with weak acid pH and medium nitrogen supply. The research was carried out on autumn oilseed rape crops, in the following fertilization variants and application rates: UREE 46% total N; UREE Z 45.7% N total with nitrification inhibitor up to 80%; UREE ZL 45.7% N total with urease inhibitor up to 50%; UREE NDP 45.7% N total with urease inhibitor up to 50% and nitrification inhibitor up to 80%; UREE DMPP 45.7% N total with volatilization reduction up to 95%. For these crops, 300 kg/ha 16:16:16 complex fertilizer and 120 kg/ha UREE were applied, from the described above varieties. There were no significant differences in soil pH and total nitrogen, available potassium increased significantly, and available phosphorus decreased slightly in all treatments. Application of stabilized and coated urea fertilizers resulted in a moderate improvement in soil SOC.
