1. Networks of Precision Farming Trials to Evaluate and Improve Nitrogen Management for CornMost research to improve nitrogen (N) management has been conducted at relatively few locations on experimental farms. The advent of precision farming technologies offers the potential for producers to collect data on their farms. The objective of this paper is to describe how organized networks of producers using precision farming technologies can evaluate and improve N management practices. Pairs of N management practices were evaluated across many fms. Treatments were applied in alternating... B.W. Van De Woestyne, A.M. Blackmer, T.M. Blackmer |
2. Relationship between Nitrogen Rate and Weed Removal Timing on Corn YieldWeeds actively compete for nitrogen in corn grain production systems. Field studies were conducted in 2009 and 2010 at the Michigan State University Crop and Soil s Research Farm in East Lansing , MI to evaluate the effect of N application rate and weed removal timing on grain yield . Treatments included four preplant incorporated rates of urea (0, 67, 134, and 202 kg N ha - 1 ) and four weed removal timings (5, 10, 15, and 20 cm) based on average weed canopy height. An additional season- long weed-free... |
