Last Saturday, it was a mostly sunny but cool day. CPS finished up with the application of the fertilizer for 2018. This was mostly phosphorus and potassium, (P & K) with some micronutrients. These are applied according to a map-based prescription, The spreader truck varies the rate of application of the nutrients as it moves across the hills and flat parts of the fields. The maps are developed using the results of sampling the soils, overlaid with maps of the previous year’s yields–accounting for the nutrient removal by the previous crop.
This concludes the application of granular fertilizers for the 2018-crop corn and soybeans. The next nitrogen application will come on the wheat crop in late winter-early spring. In late March or early April (depending on current conditions) we will apply the nitrogen for the 2018 corn crop, in the form of anhydrous ammonia. It will be knifed into the soil, ahead of planting time, and applied according to a variable-rate prescription map. Those prescription maps will be written this winter. It’s a good office task on a cold, blustery day.
Have a blessed week.
