Corn growth stages are estimated for 41 sites in 10 states and yields are estimated for select irrigated and rainfed sites, based on the Hybrid-Maize model and input from specialists and educators across a 10-state area as of July 18, 2017. The authors note that these early season yield forecasts vary widely, particularly for rainfed fields, and may change considerably by end of season.
This article discusses data and data collection for the Yield Forecasting Center forecasts of crop phenology and yield for 2017, including a map of the site locations and specific data on crop management and soil types for each site.
Following heavy spring rains, farmers may be interested in testing for soil nitrogen availability. This article notes a new publication from Iowa State University on using the Late Spring Soil Nitrate Test (LSNT) as well as other options for assessing soil nitrate.
Farmers are increasing their soybean plantings for 2017, which likely means some are shifting to soybeans-after-soybeans. This article looks at what you should be considering at planting time as you consider changing your cropping sequence.
As you evaluate the cost of inputs, consider this: Only focusing on expenses without subsequent income changes is misleading. The most profitable plan uses the most profitable inputs. Is a starter fertilizer one of those inputs? The authors look at university and grower research under various conditions to see when a starter fertilizer offers economic benefits.
