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.
