We are moving into spring work quickly here in 2019, including the application of fertilizer. Whether fixed- or variable-rate fertilizer application, it is important that proper maintenance, setup and calibration of spreaders is carried out. Annual calibration is necessary for accurate and uniform application of fertilizers.
While technology on spreaders, especially variable-rate technology (VRT) spreaders, has significantly increased in the last 10 years, the technology being adopted does not directly correlate to accurate field performance. Crop yield can potentially be impacted if incorrect rates are applied or non-uniform application occurs. There are a number of variables that impact the quality of dry fertilizer application, which includes the operator, fertilizer source properties, applicator and conditions during application. Here are a few notes to consider as we approach spring with work related to making sure the right source is accurately placed at the right rate.… Continue readingRead More »
