551 - Starter Fertilizer Provides "Bang for your Bucks"
4-11-11
Starter fertilizer has provided great benefit for those using it for nearly 20 years. About 75% of all growers used it in 2010. However increased usage has slowed in recent years. Even in 2010 with an early planting date starter fertilizer increased revenue by nearly $30/acre and P fertilizer cost was reduced by about $27 per acre. Starter fertilizer use may be especially beneficial when using conventional varieties to get the crop off to a fast start to compete better with weeds.
