Maximizing Fertilizer Efficiency with Peak Fertilizer Prices

Dr. Kitty O’Neil, Field Crops Specialist, CCE NCRAT

Plan ahead and plan thoroughly to minimize fertilizer costs in 2023.  We’re all familiar with the 4R approach to maximizing fertilizer and nutrient efficiency, but we’ll talk about the small details in its implementation, throughout the whole cropping system, to ensure accuracy and to minimize the need for purchased nutrients.

This presentation will share research results that answer the following questions:
What is the fertilizer replacement value of manure?, How does injection of manure in alfalfa impact the crop?, Can shallow incorporation be as effective in conserving N as deeper incorporation?, Can no-till planting be compatible with manure injection?,  What is the carry over benefit of manure application?

This seminar will outline a strategy for corn production that targets manure nutrients and purchased fertilizer where they are needed and conserving where needs are met by nutrient turnover from organic matter and drawing down previously built reserves.

We will discuss fertilization practices that optimize winter wheat production for grain and triticale production for forage. We will also discuss soybean production and fertilization practices that should be considered in corn grain / soybean rotations.

Quality forage from hay crops is the foundation of profitably raising dairy and livestock, there is no substitute for good yields of good quality hay and silage.   If you’re going to get this right, you’ll need a solid plan for meeting the fertility needs of this humble, and sometimes over looked crop.  This workshop will help you make the most of your on-farm fertility sources, and sort through how to profitably use purchased inputs to get a good return on your investment.  We will consider needs of alfalfa, grass and mixed stands for all major nutrients as well as pH and lime.

Advances in sensor technologies and analytical tools (machine learning and spatial statistics) now make it possible for farmers to be create management zones and make more informed decisions about crop inputs and nutrient management. In this session, we will talk about gathering high quality sensor-based data, creating yield maps and management zones for the farm, making use of grid-based soil.
