Micronutrient Usage

Zinc, a common micronutrient for dry beans, was applied to 53% of Northarvest respondents' acres, nearly the same as in 1997. Zinc was applied to 39% of Minnesota and 59% of North Dakota respondents' acres, which is down from 1997 for Minnesota but about the same for North Dakota. Other micronutrients were used on 11% of Northarvest, 13% of Minnesota and 11% of North Dakota respondents' acres, nearly double the usage in 1997 (Table 23).

A single application of zinc was made by 97% of Minnesota and 95% of North Dakota respondents
who answered the question. Two applications were made by 3% of respondents in each state and three applications were made by 2% of North Dakota respondents. Most respondents in both states made but a single application of other micronutrients (Table 24).
