Umesh C. Gupta; D. C. MacKay Canadian Journal of Soil Science 1968. doi:10.4141/cjss68-033
Other claims from this paper (15)
- Intervention effect Applied Mo raised cauliflower yield by 2000–5000 percent, depending on soil series.
- Intervention effect Applied Mo raised spinach yield by 400–900 percent.
- Intervention effect Applied Mo raised barley yield by 20–400 percent.
- Intervention effect Applied Mo raised timothy yield by 90–400 percent.
- Intervention effect Applied Mo raised alfalfa yield by 150–400 percent.
- Observation Mo content in crops ranged from 0.05 to 0.85 on untreated soils and 0.64 to 6.62 ppm on treated soils.
- Observation After harvest, 81 to 86% of applied Mo was in crop tissue or exchangeable soil Mo.
- Observation Exchangeable soil Mo and crop Mo under treatment correlated positively with untreated-soil crop yields.
- Observation Exchangeable soil Mo and treated-crop Mo were negatively correlated with yield response to Mo.
- Observation Applied Cu caused no significant yield response in four tested crops.
- Observation Hudson barley kernel yield increased on three soils with applied Cu.
- Observation Applied Cu raised Hudson barley kernel Cu content by 400%.
- Observation Crop Cu content ranged from 2.5 to 8.5 ppm untreated and 6.6 to 13.2 ppm treated.
- Observation After harvest, 85 to 94% of applied Cu was recovered from plants or exchangeable soil Cu.
- Observation Exchangeable soil Cu showed no apparent relationship to crop Cu content.
