Converting to a direct seeding system can change soil fertility characteristics because of reduced soil disturbance. You will need to adjust your fertilizer management practices to respond to any short- or long-term changes in soil fertility.

Direct seeding systems range from high disturbance, where the entire soil surface is disturbed, to low disturbance, where surface disturbance is minimal. Management practices for high-disturbance systems tend to be more similar to those for conventional systems while low-disturbance practices are less similar.

In general, when fields are converted from conventional tillage to direct seeding systems, several changes affecting soil fertility management tend to occur:
