Observing the fodder crisis

The national fodder crisis is back in the main stream news- with reports of grass growth 50% below normal and silage stores nearly empty.

But this crisis has been developing since summer last year and has crept across the country from the north west to the south east.

The main reason is the seemingly relentless rain and low temperatures. The rainfall problem is characterized not so much as excess rain (though accumulated rainfalls are above normal) but by its remorselessness – it has rained continually so that some places haven’t seen two dry consecutive days since last year, so soils haven’t had a chance to dry. Soils that are very wet cannot be trafficked without damaging them, – so many farmers were unable to get the usual harvest of silage toward the end of the summer, so stores were low. The rain continued so farmers had no option but to bring cattle indoors and feed them the stored fodder (cattle can do as much damage to wet soils as  a tractor).

Unfortunately the rain continued which meant animals has to stay indoors and this coupled with a cold late spring has meant that across the country grass has not started to grow. This effect of a cumulative seasonal impact (wet autumn, cold spring) is being studied by one of our PhD students Mohana Logakrishnan- who is looking at historical weather , satellite and farm records to build a model that can predict what the final economic impact of the current conditions will be at the end of the year.

Another student, Richa Marwaha  is building a national biomass estimator using satellites so we can measure the amount of grass growing in the country and be able to estimate what the national fodder harvest each year is. One of her outputs is February’s map of the month.

Our newest PhD student Azucena Castaneda is studying ways of improving the calibration of Met Eireann’s rainfall radar, so we can get real time estimates of current and cumulative rainfall at any location in the country. These will be combined with Sentinel 1 images to see if we can estimate soil moisture/SMD.

Finally our fourth student working in the area is Rob O’Hara and he is using satellites to measure the extent and effectiveness of field drainage. Obviously the impact of rainfall on soils varies with the soils capacity to drain the water away. If you are farming in an area of “heavy soils” then the drainage can be improved though the installation of drains (either ditches or underground drains) and Rob’s work has used Sentinel and Landsat to distinguish drained and un-drained fields and to look at the impact on grass growth of drains.

One of his outputs, actually looking at the recovery time of grassland after inundation/flooding, shows how, even if spring arrives with a bang it’ll be weeks before some farms, especially on un-drained fields in the BMW region will be back to “normal”.


depression of ndvi in summerThis plot using NDVI as a proxy for grass growth (for non-remote sensors, the higher the value, the more grass is growing) looks at fields inundated in the floods of 2015/16. What this tells us is that fields still flooded after Feb 11th had lower grass growth in May, June and July than expected- and at the extreme, fields that only drained by April 11th had very reduced grass growth in May and still reduced growth in June. So farms that have been inundated for long period, as many in the NW have – will still be feeling the effects on grass growth in June this year, even if the weather picks up by mid April. This sort of impact will have knock-on effects on farm management for the rest of the year and could potentially leave these farms vulnerable next winter to even a relatively mild seasonal shock.


Harris© Live Free Webinar: Quickly Assess Your UAV Data Quality In The Field

Quickly Assess Your UAV Data Quality In The Field    Live Webinar by Harris Geospatial Solutions, Inc.

Live Webinar | April 17

One question a UAV pilot will inevitably ask in the field is “did I collect all of the necessary data for the project?” With this in mind, PrecisionPass was developed to quickly assess UAV imagery and answer this question in the field, rather than having to wait until you’re back at the office.

Immediate feedback on your collection reduces the risk of failures during the analysis stage, all but eliminating the need to re-fly a mission, so customer needs are met in a timely and cost-efficient manner. You can think of PrecisionPass as an incredibly easy-to-use and understand insurance policy.

Attend this webinar and see how PrecisionPass can:

  • Automatically check the saturation, contrast, EXIF tags and/or associated metadata file, and gaps between scan lines (for push broom)
  • Ensure that data collected has proper overlap, coverage, and GSD for stitching and analysis purposes
  • Provide a “texture map,” which gives you a rough draft of what the final orthomosaic will look like
  • Help pilots improve their capture techniques over time Less
When: Tuesday, April 17

EARSeL SUMMER SCHOOL Sentinel for Applications in Agriculture

Sentinel for Applications in Agriculture

EARSeL SUMMER SCHOOL is open to early career scientists or employers, such as Ph.D. students, young postdoctoral scientists, technicians specialized in Earth Science disciplines, wishing to expand and improve their knowledge and skills on EO in Agriculture.

In-field exercises! 

These will be organized to collect data through ad-hoc instrumentation: spectral measurements, drone imagery, proximal sensor on tractors, etc. Samples’ collection for testing in proximity (weather permitting) of scheduled acquisition of Sentinel data is also planned.
  • Participation is limited to a maximum of 20 students: a selection based on CVs and motivation letters will be applied.
  • APPLICATION DEADLINE: Candidacy has to submit by April 30th, 2018
  • DATE & TIME: September 17th to September 21st, 2018.
  • LESSONS START: at 12:30 PM on Monday Sept 17th and end at 01:30 PM on Friday Sept 21st.
  • FEES: the cost is 950 Euro to be paid to AIT within 30/06/2018
Fees include attendance to the lectures and laboratories (including in-field excursions), accommodation and luncheons costs. Travel costs are not included. (Financial support is not available).

Plough and the stars. Remote sensing in Engineers Ireland Journal

I recently wrote a general interest piece on remote sensing, Copernicus and agriculture for the Engineers Journal published by Engineers Ireland.

Agricultural Map of the Month

We often get asked to produce maps by colleagues and for one reason or another they don’t get a wide audience. So we though we’d take the best request each month and turn it in to the “Map of the Month“.

First of our new lab member, Jesko Zimmermann has produced a very nice map based on OSI Prime 2 data showing average agricultural field size in Irish townlands.
