Crops of swedes were grown in a dry season (1949) and a wetter season (1950) with and without nitrate fertilizer, using three cultivation treatments, shallow (2 in.) and deep (8 in.) ploughing and tine cultivation, were used. Ploughing had no advantage over tine cultivation as regards crop yield or nitrate accumulation in the soil. Correlations between nitrate content of soil at various depths using the three cultivation methods and various soil factors and yield of crop and uptake of nitrogen are discussed, and the effects of application of nitrate fertilizer on accumulation of nitrate in the soil are examined.
