- Intervention effect Sulfur coated urea increased available N in the surface 150 mm soil zone in fall 1981 and spring 1982 compared with ammonium sulfate or ammonium nitrate.
- Intervention effect Available soil N in the 150-300 and 300-450 mm soil zones was largely unaffected by N source or N rate during sampling.
- Association Leaf-soluble NO3-N of strawberry plants at full bloom was positively correlated with available N in the 0-150 mm soil zone (r2 = .63).
- Intervention effect Strawberry yields in 1981 and 1982 were not influenced by N source or rate.
- Intervention effect Individual strawberry weights were increased by 15% at the initial harvest with sulfur coated urea.
- Observation In the laboratory incubation study, ammonium sulfate was readily soluble in the soil solution.
- Observation In the laboratory incubation study, sulfur coated urea (SCU) was slowly soluble in the soil solution.
- Association Under greenhouse conditions, available soil N and runner production were correlated (r2 = 0.87).
