Chemical and physical changes in standing cereal straw residues in no-till fallow and its relationship to nitrogen and phosphorus availability

Adjustments to nitrogen and phosphorus fertilization rates may be required in fields which receive a no-till (herbicide) fallow treatment as compared to the conventional tillage fallow. For example, there is potentially greater immobilization of nutrient in no-till fields.

IPNI-1993-CAN-SK11

In drier regions of the Great Plains such as southern Saskatchewan, Alberta, and parts of Montana and North Dakota, cereal - fallow rotations continue to dominate, mainly because of the need for a fallow period to shore sufficient moisture to produce economic yield and lower the risk of crop loss.
