The system evaluated is a design that combines planter and sprayer technologies to allow clients to plant crops while simultaneously spraying initial fertilizer on or in close proximity to the seed.  The system is an idea Capstan Ag Systems has been pursuing for around 15 years, and has recently been revived in a partnership with Great Plains Manufacturing Company.  Great Plains Manufacturing released the final product under the name AccushotTM at the 2015 Agritechnica Farm Show in Hannover, Germany.  When planting, particularly corn in twin or narrow rows, it is difficult to spray initial fertilizer while planting seeds.  In the past, this has been done by walking behind the planter and using backpack sprayers to apply the initial fertilizer on quarter sections of the field.  Agronomists have found that the survival rates and condition of the plants are significantly better if the initial fertilizer is applied in the furrow with the crop seed.  Therefore, it would be beneficial for farmers to have the technology, such as AccushotTM, which applies the initial fertilizer in the furrow while planting the seed.  However, in order for it to be marketable to farmers, the system would need to include a method of verifying the machine’s performance.
