2024 IFS webinar series

A programme of webinars covering a variety of topics relating to fertiliser production and crop nutrition

During 2024 the IFS will continue to organise webinars for those involved and interested in the production and application of fertilising products. These webinars will be in the same format as in previous years.

Society Members will be able to attend all these webinars without charge, as well as having free access to the presentation charts, a recording of the webinar, and a pdf copy of the written paper, where applicable. For UK attendees, each webinar will be worth BASIS FACTS CPD points.

Non-members are also welcome to attend, for a charge of £25 per webinar, or £35 for a webinar plus access to a pdf of the presentation charts, recording of the webinar and pdf of written papers, where applicable. Selected webinars will be free to all.

For those who are unfamiliar with the quality of Society talks, we are offering a ‘taster’, to enable non-members to attend one webinar (only, excluding recordings and pdfs) for free. To take advantage of this offer, enter the code IFSFREEWEB into the Coupon box in your basket when registering for a webinar.

Detailed information on the webinars that comprise this programme is shown below. Updates will be added as these are finalised. Webinar registration will open for each webinar as its details are confirmed, and will be accessed from the section for each webinar, below.

Reaching production and environmental goals through soil specific potassium fertiliser advice for grassland

Thomas McCarthy, Teagasc / SETU Waterford, Ireland

This research investigated the optimisation of K fertilisation to grassland, categorising Irish soils using their inherent characteristics that influence K dynamics and to develop soil specific K fertiliser advice to promote increased sustainability on farms. The research developed a system of soil categorisation criteria that will lead to the development of more soil specific advice to optimise fertiliser K use.

Root iron plaque as a dynamic pool of phosphorus in rice grown under different water management

Sara Martinengo, University of Turin, Italy

Sara investigated iron (Fe) plaque mineral composition and the uptake of P in rice. The issue is that oxygen released by rice roots, grown in submerged paddy soils, causes the precipitation of iron (Fe) on the root surface. The Fe plaque that forms can adsorb phosphorus (P) from the solution, potentially decreasing the plant P availability. Her research results will help farmers to calibrate their P fertilisation based on their irrigation practices, mitigating the impact of P on water quality and saving unnecessary expenses in terms of money, resources and energy.

Tailored cover crop mixtures for improved soil P exploration and subsequent crop nutrition

Henrique Rasera Raniro, University of Natural Resources and Life Sciences, Vienna, Austria

This research investigated the P-related effects of cover crops on the soil and subsequent crops. Henrique’s key finding was that, by combining synergistic species with efficient P acquisition traits, cover crops may be able to explore less available P pools, which are not normally available to cash crops. Being reintroduced into the soil, a plant’s biomass gradually mineralizes, releasing bioavailable P and indirectly giving subsequent crops access to the legacy P.

This webinar should be worth 1 AP and 1 PN BASIS FACTS CPD points, which have been applied for.

Developments in crop and soil scanning technology

13.00 GMT / 14.00 CET

Practical application of fusing spectroscopic techniques in routine soil analysis: Lab-in-a-Box (LiaB) concept

Matteo Poggia, Agrocares, Netherlands

Modern spectroscopic techniques give an opportunity to analyse soil samples more time and cost effectively, while eliminating the need to use substances harmful to the operator and the environment. Above that, their simplicity of operation allows to expand the circle of users as no thorough “know-how” of analytical chemistry is needed. Most interesting is that these attributes do not have to come at the expense of accuracy. The improvements in instrument manufacturing, computing power and advanced calibration modelling algorithms have provided the tools to realize a sensor fusion concept combining mid-Infrared spectroscopy and X-ray fluorescence that meets these criteria: the Lab-in-a-Box (LiaB). In this webinar, we will briefly discuss the theoretical background, demonstrate the procedure, while highlighting the strengths and weaknesses of the process.

The science and operational experiences of the ICLeaf crop leaf scanning technology

Prof. Uri Yermiyahu, Volcani Institute, Israel and  Sanjay Namdev Biradar, ICL Fertilisers India

Uri will discuss Reforming crops’ Mineral Diagnostics by Chemometrics

World farming requires precision fertilization to eliminate contaminations, improve crops’ productivity, and ensure sustainability. Yet, chemical mineral analyses are overly expensive and labour-intensive to substantiate large datasets of plants’ nutritional status, rendering farming to rely on discrete measurements for fertilization updates. Hence, we set to restructure nutritional diagnostics in agriculture. First, we developed a unique experimental setup to produce a wide range of mineral concentrations in multiple crops. Then, we turned to analytical tools in alternative industries, mainly NIR and X-ray fluorescence used by the mining and pharmaceutical industries for mineral analyses. Finally, we integrated an array of statical tools to adjust chemometric tools to the mineral matrices in various plant tissues. The novel chemometric projections fitted chemical analyses of macro and micro-elements’ concentrations in multiple crops (e.g., vine, tomato, almond, citrus, and avocado leaves). The error range was ±5% of laboratory analyses (corresponding to common variability between laboratory assays), and repetitions were redundant. Moreover, it is a rapid analysis, and its procurement costs are significantly lower than current laboratory practices. We recently extended our efforts to the extension and commercial sectors, supporting field laboratories in India and Israel. Now, we are set to survey numerous crops throughout all their phenological stages at various growth conditions and produce the large datasets required for modern decision-support algorithms to guide farming.

Sanjay will then describe the operational experiences of using the technology, covering:

Protocols and collection of leaf samples

Processing the samples in the lab

Generating reports

Impact on Yield,

Quality Improvement

Impact on Fertiliser application

Impact on cost saving on fertiliser application

Social Impact- sustainability.
