Apps and Mobile Sites for Mobile Devices on the Farm

It didn’t take long for the phrase “there’s an app for that” to be seen and heard regularly in the phone and mobile deviceUNL Extension Educator Gary Zoubek shares app information via his iPad during lunch at the Nebraska Technologies Association Conference world.  Today, there are many apps and mobile websites that can be fantastic tools for producers to use in decision-making.  University of Nebraska Extension has developed several mobile apps to take a look at and be sure to visit our site often to learn of additional new apps.  

In addition to our Extension Apps, Dennis Kahl, UNL Extension Educator, and I have also compiled a list of a few mobile apps that we think could be useful to farmers yet this year as they get closer to harvest, but also for next year to test out and see if they will indeed help them do work quicker and make decisions more accurately.

Today we are going to highlight a few mobile applications and mobile websites that producers may be using now as they make preparations for fall harvest.

  • UNL CropWater – provides an easy way to estimate soil water status based on Watermark sensors installed at depths of 1, 2, and 3 feet. With these sensor readings, the Crop Water app will estimate the water used as well as what is still available for Nebraska soils.
  • Market Journal –  Television for Ag Business Decisions.  Weekly crop reports, markets, weather and current insect, MJ app from UNL Extension based off Market Journal TV show http://marketjournal.unl.edu disease and harvest issues. It was also listed at Agriculture.com’s #1 ag app for 2013.
  • RealAgriculture – focuses on the issues that are impacting agriculture.  The site is focused on getting farmers the opinions on issues so that you not only get the news but the insight into what the news means in the production business.
  • DTN/PF – The Progressive Farmer – provides market data, link charts to market data for single, seamless view of how the latest prices correlate with current market trends.
  • Farm Progress – Keep up on local ag news, grain and livestock markets, enhanced weather and blogs as well as Nebraska Farmer magazine.
  • Husker Harvest Days Show – Maximize your time at Husker Harvest Days with this application that includes exhibitor and category lists, show maps and other tools to help you maximize your time at the show.
  • Ag PhD Harvest Loss Calculator – Allows farmers to estimate yield loss before and during harvest by recording the number of individual corn, soybean, wheat, sorghum, barley or oat seeds found on the ground in a square foot.
  • Combine Performance Optimizer by John Deere – Help operators adjust and set the critical settings for next year’s harvest of small and large grain crops to improve machine performance.
  • Calibrate My Sprayer – Aid in the proper calibration of spraying equipment.
  • In addition to the apps listed above, Crop Life featured a story of the Top 13 Mobile Ag Apps for 2013 and Agriculture.com has a list of mobile apps.  Take a look at these as well.

With wireless technology available in most areas of the state, we utilize Verizon Wireless with our mobile devices in the field and in our communities to update various social media outlets such as Twitter, Facebook and blogs.  Mobile access has allowed University of Nebraska Lincoln Extension to provide current information and situations in the field at all times.  We encourage producers to subscribe to various resources including:

Goss’ Wilt in Corn

Goss’ wilt was found this week in corn damaged from Memorial Day storms in Clay County.  I’ve also received pictures that appeared toGoss' Wilt in Corn in Nebraska with characteristic black "freckles". be Goss’ from crop consultants in other areas of the State.  Goss’ wilt lesions have a wavy edge, have a varnished look to them when wet, and have characteristic black “freckles” within and particularly along the lesion edges.  We are seeing some plant death due to the systemic version of Goss’ wilt.  This can be seen by taking a cross-section of the stem and looking for orange discoloration in the vascular bundles.  Because this is a bacterial disease, fungicides are not effective in controlling Goss’ wilt.  If you are interested in trying a product that is labeled for treating bacterial diseases in corn, we would recommend you test its effectiveness via on-farm research.  Spraying in a paired comparison treatment design will give you a true answer if the product made a difference for you or not.

To do this simply:Paired Comparison Design with buffer rows for on-farm research comparison

1-Spray a pass or round with the product (depending on sprayer size) to ensure you can harvest two passes from the center of the treated area.
2-Skip the same amount of distance as you previously sprayed.
Repeat steps 1-2 at least three more times

Mark a few plants in each plot and take photos throughout the growing season to determine if disease progresses or not.  You may also wish to keep track of percent of plants affected in each untreated and treated area throughout the season, and check for percent stalk rot and harvest population in each area before harvest as well.

Make sure to harvest two passes from the center of each treated and untreated Split plot harvest design for on-farm research comparisonarea.  Then compare the weights as shown in the harvest figure.  Please let Jenny Rees jrees2@unl.edu (402) 762-3644 know if you decide to conduct this study and if you have any questions!

Crop Update 6-20-13

The sun has been welcomed and crops are rapidly growing in South Central Nebraska!  Corn right now is between V6-V8 (6-8 leaf) for the most part.  Quite a few farmers were side-dressing and Corn that's been hilled in south-central Nebraska.hilling corn the past two weeks.  It never fails that corn looks a little stressed after this as moisture is released from the soil and roots aren’t quite down to deeper moisture.

Installing watermark sensors for irrigation scheduling, we’re finding good moisture to 3 feet in all fields in the area.  The driest fields are those which were converted from pasture last year and we want to be watching the third foot especially in those fields.  Pivots are running in some fields because corn looks stressed, but there’s plenty of moisture in the soil based on the watermark sensor readings I’m receiving for the entire area.  So we would recommend to allow your crops to continue to root down to uptake deeper moisture and nitrogen.

The last few weeks we observed many patterns from fertilizer applications in fields but as corn and root systems are developing, they are growing out of it.  We’ve also observed some rapid growth syndrome in plants.  This can result from the quick transition we had from cooler temperatures to warmer temperatures, which leads to rapid leaf growth faster than they can emerge from the whorl.  Plants may have some twisted whorls and/or lighter discoloration of theseOn-farm Research Cooperators, Dennis and Rod Valentine, get ready to spray their corn plots with a sugar/water solution.  Their study is to determine the effect of applying sugar to corn on yield and economics.  leaves, but they will green up upon unfurling and receiving sunlight.  This shouldn’t affect yield.

Damping off has been a problem in areas where we had water ponded or saturated conditions for periods of time.  We’ve also observed some uneven emergence in various fields from potentially a combination of factors including some cold shock to germinating seedlings.

We began applying sugar to our on-farm research sugar vs. check studies in corn.  We will continue to monitor disease and insect pressure in these plots and determine percent stalk rot and yield at the end of the season.

Leaf and stripe rust can be observed in wheat fields in the area and wheat is beginning to turn.  We had some problems with wheat streak mosaic virus in the area again affecting producers’ neighboring fields when volunteer wheat wasn’t killed last fall.  Alfalfa is beginning to regrow after first cutting and we’re encouraging producers to look for alfalfa weevils.  All our crops could really use a nice slow rain right now!
