Should you be applying lime?

Fall is an excellent time to test soil pH and determine whether any lime needs to be applied for future crops. Proper soil pH is important for nutrient availability, herbicide activity, and crop development. For most soils, additional lime is not needed every year.


Decreasing loss when using urea

Selecting the right nitrogen source when fertilizing pastures and hayfields has always been important in nitrogen use efficiency. For many years we have had the option of using either urea or ammonium nitrate as the nitrogen source in our fertilizers. A basic recommendation was to use urea in spring, but use ammonium nitrate in summer and early fall. Urea was usually cheaper, but more prone to nitrogen loss due to volatilization, which occurs in hot weather with limited rainfall.

The ‘four Rs’ of nutrient management—the right source of nutrients, at the right rate, at the right time, in the right place—are additional best management practices to consider when nutrient management planning.
