Crop varieties and dates and rates for management operations in 2018 and 2019.
1Alfalfa crops harvested in 2018 and 2019 were planted in 2017 and 2018, respectively.
2Oat crop harvests in 2019 were done in two days because of equipment complications.
3Soybean germination in 2018 was lower than in 2019 because of poor drainage in the soil. Oat and red clover were intercropped in the 3-year system. Oat and alfalfa were intercropped in the third year of the 4-year system, and alfalfa was overwintered after oat harvest.
Error 1: The 2018 soybean planting date originally stated “Jun. 3”. This has been changed to “May 17”.
Error 2: Missing 2018 soybean herbicide application date and type.
Error 3: The 2019 oat harvest date originally stated “Jul. 22 and 24”. This has been changed to “Jul. 24 and 29”.
Error 4: Incomplete 2019 red clover cultivar name.
Error 5: Missing year in 2019 alfalfa planting date.
Error 6: The 2019 alfalfa harvest date originally stated “Jun. 7, Jul. 12, Aug. 26,”. This has been changed to “Jun. 7, Jul. 12, and Aug. 26”.
Error 7: Footnotes were missing from Headers “Planting date”, “Harvest date”, and “Crop density”.
Table 2 has been updated as shown below.
