Other claims from this paper (9)
- Intervention effect On the light soil, autumn-given treated ammonium sulphate increased wheat yield by 5–4 cwt/acre with a double dressing.
- Intervention effect On the heavy soil the nitrification inhibitor had no effect on wheat yield.
- Intervention effect Dressings of 50 lb N/acre in autumn or spring increased wheat yields equally.
- Intervention effect With 100 lb N/acre, a spring dressing increased wheat yield slightly more than autumn dressings.
- Intervention effect Calcium nitrate at 75 lb N/acre gave significantly better wheat results than ammonium sulphate on the light soil.
- Intervention effect The nitrification inhibitor did not affect the speed of N uptake or the total N uptake from spring-given fertilizer.
- Observation Without fertilizer-N, winter wheat on the sandy-loam yielded 17 cwt/acre.
- Observation Without fertilizer-N, winter wheat on the clay yielded 46 cwt/acre.
- Observation With the double spring dressings, winter wheat yields were 52 and 56 cwt/acre on the two soils.
