The New Maizex Nitrogen Tracker 4.5

The Maizex N Tracker will allow corn producers to assess nitrogen recommendations on a single spreadsheet.  The spreadsheet will include both field based and soil nitrogen testing based recommendations. The fundamental calculations in this spreadsheet are based on the OMAFRA N Calculator or OMAFRA PSNT Recommendations with some enhancements and adjustments made based on years…

Introducing the Maizex P and K Tracker

Fine tuning our nutrient applications is an ongoing process. Phosphorus management in Ontario is important on two fronts; ensuring we have productive soils to maintain high yields as well as reducing losses to water sources. Soil test K levels that have fallen in the last 10 years pose a threat to increasing yields. As farms…

Manganese Deficiency

Manganese (Mn) is one of nine essential micronutrients for plant growth. Corn is only a moderate consumer of manganese and so deficiency in most mineral soils is rare.  High organic matter (muck) soils can be more frequently diagnosed with some level of Mn deficiency.  In mineral soils under dry conditions and where the soil is…

Seedbed and Corn Stand Evaluations

Before we let corn planter performance and early corn stands get too far into the rearview mirror, here are a few observations from Spring 2016. 1. Residue Management High residue situations can improve soil structure and water infiltration, but residue pinched into the seed trench or interfering with emergence may set a plant back so…

Late Nitrogen Insights

There is unprecedented interest and investment in applying nitrogen on corn later in the season.  By later, we mean applications that are beyond the traditional planting or sidedress timings and generally between the V10 to VT (tassel emergence) stages. Some key questions need to be considered as we aim to shift more of the corn…
