Starter fertilizer (10-34-0) in corn production has traditionally been recommended for fields with low phosphorus levels, or cool soil temperatures due to early planting, high residue cover or nothern location. In these conditions, starter fertilizer placed near the developing seed provides easily accesible nutrients until soil conditions improve and a larger root system is established for a stress-free emergence.

 

Corn Grain Yield Increases From Starter Fertilizer Applications Are Most Likely:

• ln Northern portions of the Corn Belt, regardless of tillage practices

• When cultural practices such as no-till or minimum tillage are utilized

• On coarse textured and or low organic matter soils

• On poorly drained or cold soils

• On low testing P and K soils

• When nodal root systems are severally impeded by stresses

• When soils pH is unusually high or low

• When substantial drought stress is likely
