Other claims from this paper (9)
- Observation Considerable leaching or transfer of nitrogen, phosphorus, magnesium and potassium occurs in the standing crop before litter deposition.
- Observation Potassium showed a 96% turnover in the vegetation before the end of the first year.
- Observation Silica showed a distinct rising trend with age of the standing crop.
- Intervention effect Dry matter losses in litter were about 50% more rapid for foliage than for flower stalks.
- Observation Total ash after 2 years of litter decomposition was approximately twice the initial level in foliage and flower stalks.
- Observation Nitrogen percentage showed a decreasing trend in the standing vegetation during the first year.
- Observation Nitrogen levels increased on a dry weight basis during the litter phase.
- Association Nitrogen increase in litter relative to faster dry matter loss suggests a narrowing of the C/N ratio as decomposition progressed.
- Intervention effect Foliage from control plots had higher nitrogen concentrations than foliage from burned plots.
