 Abstract
Liquid livestock manure (LLM) has been used as a nitrogen fertilizer source for horticulture plants. LLM contains organic nitrogen (N), ammonium, nitrate, and nitrite. The amount of nitrate and nitrite in LLM are usually small compared to the amount of ammonium in it and so they can be negligible if total nitrogen (N) concentration in LLM is higher than . However, if total N concentration in LLM is less than , the amount of nitrate and nitrite may affect total N concentration in LLM. Currently, Kjeldahl digestion method is mainly used for ammonium-N in LLM. Therefore, it is ineffective to analyze nitrate-N and nitrite-N. The objective of this study was to evaluate whether the total N concentrations are affected by the amount of nitrate-N and nitrite-N with diverse LLMs by Kjeldahl method (with and without Devarda`s alloy after Conc. sulfuric acid digestion). Five liquid livestock manure samples were collected at swine farms in Ansung and Icheon. All LLM samples were stored at , subsampled at every day for 90 days, and analyzed for total N, ammonium-N, and nitrate-N. At the day, LLM samples were analyzed with and without Devarda`s alloy after Conc. sulfuric acid digestion. Potassium nitrate, ammonium nitrate, and ammonium chloride were used to determine the N recovery percentages. Total N concentration ranged from 560 to . Nitrate-Ns were found in all LLM samples, ranged from 21 to . N recovery percentages with potassium nitrate were 0 % without Devarda`s alloy and 100% with Devarda`s alloy because adding Devarda`s alloy facilitated nitrate-N into ammonium-N conversion. Total Ns were significantly different between two methods, with and without Devarda`s alloy. Total N concentrations were at LLM 4 and at LLM 5 without Devarda`s alloy and at LLM 4 and at LLM 5 with Devarda`s alloy. These results suggest that if total N of LLM is less , additional procedure such as adding Devarda`s alloy can be used to estimate the total N and inorganic N better.
