Other claims from this paper (15)
- Intervention effect Salt did not increase herbage yields in four experiments.
- Association Salt and potash showed consistently negative interactions.
- Intervention effect Salt and ammonium sulphate increased herbage yields.
- Intervention effect Salt and ammonium sulphate greatly increased sodium contents of grass and clover.
- Intervention effect Muriate of potash markedly depressed sodium contents.
- Intervention effect Salt did not alter potassium concentrations in grass or clover.
- Intervention effect Muriate of potash had consistently large incremental effects on potassium concentrations in grass or clover.
- Intervention effect Repeated application of ammonium sulphate reduced potassium concentrations.
- Intervention effect Fertilisers did not alter calcium contents of grass or clover.
- Intervention effect Three cwt. of ammonium sulphate increased grass magnesium concentration by 14% on average.
- Intervention effect Three cwt. of ammonium sulphate increased clover magnesium concentration by 4% on average.
- Intervention effect Muriate of potash (2 cwt.) or salt (4 cwt.) depressed grass and clover magnesium contents by 7.5% and 4% respectively.
- Intervention effect Reductions in herbage magnesium due to muriate of potash were greatest in late-season samples.
- Intervention effect A small dressing of magnesium sulphate increased herbage magnesium in one of two experiments.
- Intervention effect Salt in finely powdered form may scorch clover severely if applied in dry weather.
