2 Motivation By 2050 FAO predicts needed increase of 70% in cereal grains to feed 9 billion people (FAO 2012) 70% of global water consumptive use for agriculture, 40% of global food production is from irrigation agriculture (Mekonnen 2011) Estimated that 60% of 2,500 trillion liters used for agriculture is wasted for non-productive ET (Clay 2004) WHY?????? 2
3 Hypothesis Difficult to accurately measure water availability in the soil at the measurement scale of water application (individual nozzle and center-pivot) with existing point based technology. That uncertainty is 1 key factor that leads to overwatering as to not adversely affect yield. Right photo courtesy of Valley Irrigation 3
4 Solution! Only apply water when and where it is needed Turns out that it is not that easy to measure plant water use (ET) and soil water storage at the same scale, or on the scale of water application (i.e. see myriad of ET and soil moisture monitoring methods) 4

Proximal sensor, doesn t interfere with farm operations Mobile for large scale mapping or within field spatial variability for precision agriculture New tool for conducting field scale water balance studies 11

Applications: 1) Irrigation management- Use to optimize irrigation water inputs in May-June for max. irrigation in July-August 2) Precision agriculture- in-season spatial mapping 13

Built-up with updated electronics and high voltage NPMs Same basic physics as in-situ neutron probe Passive sensor, uses cosmic-ray neutrons as source Relates fast neutrons to water content instead of slow or thermal neutrons Footprint is ~1000x larger (density of soil vs. air) Probe sees about top 30 cm In-situ probe considered gold standard in agronomy and soil physics 14

26 1. Irrigation management By reducing Watermark point sensor uncertainty with CRS, there can be increased yield and reduced input costs. 26
27 1. Irrigation management By reducing Watermark point sensor uncertainty with CRS, there can be increased yield and reduced input costs. Yield: How many inches of water can we save in May and June to apply in July and August? 1 inch of water = bushels/acre, savings ~ $7k per 130 acres at $4 corn per inch of water 27
28 1. Irrigation management By reducing Watermark point sensor uncertainty with CRS, there can be increased yield and reduced input costs. Yield: How many inches of water can we save in May and June to apply in July and August? 1 inch of water = bushels/acre, savings ~ $7k per 130 acres at $4 corn per inch of water Energy: How much water/energy does that cost us over an entire growing season? 1 center-pivot rotation, ~$1-2k in energy pumping costs 28
29 1. Irrigation management By reducing Watermark point sensor uncertainty with CRS, there can be increased yield and reduced input costs. Yield: How many inches of water can we save in May and June to apply in July and August? 1 inch of water = bushels/acre, savings ~ $7k per 130 acres at $4 corn per inch of water Energy: How much water/energy does that cost us over an entire growing season? 1 center-pivot rotation, ~$1-2k in energy pumping costs Fertilizer: How much Nitrogen can we save from leaching out of the root zone? ~$0.4 per lb of N, need 200 lb per acre, savings ~$50 per lb of N per 130 acres 29
30 2. Precision Agriculture Problem: we can break field into 5400 management zones but we have very limited or no information on what is happening in each zone! Remember a point sensor represents only a point, takes about 6-12 point samples to estimate a reasonable zone average for each layer Why should I spend an extra ~30k to upgrade my pivot to variable rate if we can t make dynamic water prescription maps? 30
31 2. Precision Agriculture A point sensor represents only a point unless we tell it otherwise Why not train our point sensors with spatially representative information from the cosmicray sensors 31

34 2. Precision Agriculture Cosmic-ray rover can be mounted to existing farm equipment, ATV, sprayer, destroyer Collect 4 to 8 training datasets to train any existing point sensor and then make dynamic water prescription maps for VRI Landscapes, fields, and management zones, wet up and dry down following similar and now observable patterns 34
35 Future Steps Refine data collection and data processing currently can mapped in about ~1-2 hours per center-pivot data processing ~10-15 minutes Continue to investigate data merging strategies for combining time series data with spatial mapping (see. Franz et al GRL) Work with companies to: make hardware cost effective develop user friendly software develop cost effective business strategies (i.e. crop consultants) 35
