Since starter fertilizer came into general use, several methods of placement have been used, including starter fertilizer programs using row placement of liquid fertilizer directly on or very close to the seed. The advantage of this process is the availability of the fertilizer to the newly germinated seed. The disadvantage is that this practice may result in injury to the seed or damage to established growth after germination. This type of injury is directly connected with the placement of too much soluble salt in the small zone next to the seed. The extent of damage depends on many variables, soil moisture conditions being the most important. Other factors that can be controlled are locating the fertilizer away from the seed, reducing the amount of fertilizer by dilution and reducing the soluble salt content of the fertilizer.
