Salt index is the ratio of an increase in osmotic pressure produced by a fertilizer compound compared to a standard sodium nitrate base. The higher the salt index, the more concern there is that the fertilizer material can affect the germinating seed. The following table shows salt index for some common starter fertilizers. Table… Read the full article…
Planting depth for corn is extremely critical for proper development of the nodal root system. If the nodal root system (principal root mass for the corn plant) is located too close to the soil surface, then the nodal root system can be greatly reduced in size. The impact of a smaller nodal root system can… Read the full article…

The trend to fertilize with hog manure is growing for those farms with the opportunity to do so. When hog manure is applied according to their manure management plan, generally, most if not all of the phosphorus requirements for crop production are generally met. However, if phytate feed supplements are utilized in their modern hog… Read the full article…
The source of fertilizer had an effect on 2011 corn yields. With corn at $6.00/Bu, for equal net $ returns per acre for both fertility programs, the dry P & K program would need to be better than $50.00/acre cheaper!
