the following crop if the tops are mineralized in the growing season.
Other arable residues tend to mineralize in the late summer/autumn
leaving a large pool of SMN. Thus, N supply from beet residues on
sandy soils will be greater than from other residues where SMN can be
leached. Fertilizer recommendations on sandy soils need to reflect this.
