| Testing the addition of an alkali (NaOH) in an air cleaner (Munters A/S) connected to a finisher pig unit during the summer resulted in an average odour reduction of 47%. The measurement days were spread over two batches of pigs (summer and autumn). The average odour reduction for the entire test period was 41%. The measurements taken during the autumn did not show a statistically significant odour reduction. Furthermore, the results showed that it was possible to reduce the emission of hydrogen sulphide by 53%. As expected, the levels of ammonia and carbon dioxide were not reduced. When using 100% air cleaning, the consumption of the air cleaner for two batches of finishers (30 – 110 kg) amounted to 355 L water and 2.4 kg 27.7% NaOH solution,... |

| The objective of this study was to evaluate effects of different irrigation and N fertilization regimes by gun irrigation and drip-fertigation on potato production, and subsequently optimize the supply of water and N fertilizer to the growth condition of the specific season and minimize nitrate leaching without compromising profits. Four replicate plots of each treatment with varying predefined and model-based (Daisy and Aquacrop crop model) irrigation and N fertilization levels was used in the study. Two experiments were conducted. In experiment-I, treatments consisted of one drip-fertigation system (IdsNds) and two gun irrigation systems (GIdsN120 and GIaN120) to display the differences on growth, yield and water use efficiency of potato. All treatments... |
