13. Reasons for premium chopper • Heavy yields and long-strawed varieties. • Better straw distribution. • Cutting platforms > 6,5 m. • Fast rotting of the straw mat due to shorter cutting length. • Ideal for minimum tillage practice. • The retention of nitrogen by soil organisms can be enhanced. • Thick straw layers mixed into the root zone stop capillary water transport and cause water stress in next season.
