1 1 Adapt-N: An On-Line Nitrogen Management Tool. Background / Results from 2011 Strip Trials Harold van Es / Jeff Melkonian / Bianca Moebius-Clune Iowa Soybean Association, On-Farm Network Conference Ames, Iowa February 16, 2012

2 2 Control Points for Improving N Use Efficiency and Reducing N Losses 1. Input management - increased N use efficiency rate, timing, formulation, placement 2. Transport mechanism (drainage, irrigation) 3. Remedial actions (filters, buffers, wetlands)

3 Many sources of variation in N availability generalized recommendations less applicable for corn N needs Sources of Variability: Organic amendments (manure, compost, etc.) Crop rotations Soil type differences Soil organic matter contents (management- induced soil change) Soil and crop management Temperature Precipitation

4 Predicting N Needs for Corn: Precision Improves over Time Main Factors: snow cover spring rains summer drought high intervention nonintervention low fall winter spring summer fall 4

5 Nitrogen Management with Computational Tools Move from generalized to site-specific recommendations Allows for adaptive, real-time management - Weather conditions - Local soils and crop management Universal process-based approach - Incorporates system complexity through relevant processes Low cost Allows for progressive refinement 5

6 PNM model: Basis of the Adapt-N Tool Linkage of two simulation models: Crop growth/n uptake model Sinclair, T.R., and R.C.

14 Adapt-N Results Page Example with need for sidedress N

15 N Recommendation Methodology Mass Balance Approach CropN Harvest Total crop N uptake from planting to harvest, based on "Expected Yield" input. CropN Current Crop N uptake from planting to the current/simulated date, based on growth and N uptake according to weather data. SoilN Current Crop-available N in the root zone on the current/simulated date, based on soil, N inputs, previous soy or sod crops, crop uptake and weather effects. SoybeanN Credit Estimate of contribution of N to the current corn crop from a previous season soybean crop. SoilN postsidedress Estimated crop-available N (from mineralization/urea hydrolysis estimated N losses) from the current date to harvest. Loss postapplication Estimated post-n recommendation losses from the Adapt-N recommended N application.

34 Outcomes: What did we gain from this exercise? Soil organic matter is critical Rooting depth : tiled vs non-tiled fields Conversion of ammonium to nitrate in the soil Need to improve representation of winter processes Fall applied anhydrous ammonia/manure Initialization of model in the spring Need to improve representation of the soybean N credit Impact of flooding on crop growth? 34

50 Preliminary Strip Trial Conclusions Adapt-N generally accurately estimated lower N needs, and in some cases higher N needs In some cases Adapt-N under-predicted N needs N savings were considerable on some fields Adapt-N will need some minor adjustments Post-application loss probabilities N immobilization and soybean credit Analyses of strip trial data Aerial photos showed treatment effects when present; LSNT and corn stalk nitrate tests provided mixed results. Importance of additional year of testing (2012)

51 Current: Adapt-N for Operational in Northeast and Iowa Winter 2011/12: - High resolution climate data East of 100th Meridian 2012 season: - Strip trials - Limited it extension to other Corn Belt States - Cover crops - Inhibitors - Improvements based on 2011 data - Daily summaries; text/ alerts 2013: - Estimation of N 2 O losses 51
