Effects of Urea Treatment in Malignancies of the Conjunctiva and Cornea (with 1 colour plate)

Microbial biomass and soil respiration rate decreased after application of 150 kg NH4NO3–N∙ha−1 to different coniferous forest podzols. The decrease was already found 3 months after fertilization and was still evident after 3–5 years. Changes in pH, organic matter, or water content in the soils could not explain the decreases. In laboratory experiments, several unfertilized forest soils were treated with 2 mg of NH4NO3–N or of urea–nitrogen∙g wet soil−1. The ammonium nitrate addition resulted in severe depressions of the respiration rates during and up to 175 days of incubation and the decrease was evident after about 1 week. The urea treatment initially increased the respiration rate of the soils, but this appeared to be a transitory effect.

On Farm

Urea-ammonia treatment of straws in the tropics involves mixing 1.0 kg of air dry straw with 1.0 kg of a 40 g/kg urea solution and storing under plastic for at least 4 weeks (Schiere and Ibrahim, 1989). The economics of treatment is dependent on the cost of urea. Treatment cost would reduce, if on-farm-produced urine, e.g. cow urine, could be used as a source of urea. However cow urine is dilute and may contain only 10 g/kg urea or less (Owen, 1993). The present study therefore investigated varying concentrations of urea solution for treating wheat straw at a tropical temperature.

Carbohydrate Supplement

The yield of dry matter (DM) in a mature wheat crop can equal that obtained from three cuts of grass. Ensiled mature whole crop wheat is however characterised by a lower digestibility and lower crude protein concentration than good quality grass silage. Addition of urea at ensiling has been shown to increase the digestibility and the non-protein nitrogen concentration of whole crop wheat silage. The objectives of this study were to determine (i) the effect of urea-treatment on the in vivo digestibility of wheat of relatively high moisture concentration and (ii) the effects of the provision of a rapidly fermentable carbohydrate supplement on nitrogen metabolism in steers fed these silages.
