A high-residue rotary hoe
can be used in crop for control of small seedling crops, up to about 12” height. You will obtain optimal weed control if you use the rotary hoe in a moist soil, with a dry weather forecast.
The inter-row cultivator is a tool used for weed control used in row crops: corn, beans… Using it in small grains would require wider spacings (15” instead of 10”), and a precision guidance system to keep the shanks and shovels out of the crop rows. Timing and soil conditions are also essential when using a cultivator, especially in small seedling crops: used too early, or under dry conditions, soil can be overthrown and bury the crop.
