Arable Farming Weekly Summary
Date Range: 18 May – 24 May 2026—
Executive Summary
This week on The Farming Forum’s Arable section, the conversations predominantly revolved around fertiliser pricing and application strategies, cereal fungicide regimes, and crop management techniques for spring cereals and linseed. Discussions on fertiliser addressed price trends, product choices particularly comparing solid versus liquid forms, and issues with spreading accuracy and crop safety. Fungicide applications for spring barley generated significant interest, with growers exchanging practical advice on cost-effective chemical programs amid challenging weather conditions. There was also notable dialogue on niche crops such as linseed and winter barley, including equipment considerations and alternative varietal solutions. Additional topics encompassed glyphosate use under warm conditions, soil amendment comparisons, and advice requests for brassica crops, reflecting a diverse set of agronomic concerns at this time of the season.—

Fertiliser Pricing and Application
The Fertiliser Price Tracker conversation led the week with 29 contributions, detailing the ongoing volatility in fertiliser markets. Members debated solid versus liquid fertiliser applications, with granular products like Extran and Nitram receiving extensive comparison. Clarifications were made regarding composition differences — highlighting that Extran is a granular ammonium nitrate product with a spreading advantage, often preferred for windier sites due to better coverage over longer distances (up to 36m). Cost per unit nitrogen remains a critical consideration, with some frustration expressed over fluctuating supply and pricing structures.
Liquid fertilisers attracted interest for their precision capabilities on smaller or irregular fields. Contributions emphasised crop safety concerns, especially regarding scorch potential if liquid nitrogen applications are mistimed relative to growth stages. Some growers shared positive first-year experiences switching from granular to liquid forms, appreciating the even greening achieved across headlands. However, others preferred the work rates and simplicity of granular forms, particularly on larger acreage. Overall, active discussion confirmed fertiliser strategy remains highly farm-specific, balancing cost, accuracy, workload, and crop safety.

Cereal Fungicide Strategy and Growth Regulation
Spring barley fungicide programs were another focal point, with 16 contributions covering chemical choices and timings. The consensus leaned toward utilising generic prothioconazole products such as ‘generic Siltra’ (prothifen) due to lower cost, often applied at T1 with triazoles or strobin complements. Resistance management was a recurring theme, with a reminder that overreliance on prothioconazole risks reduced future efficacy. Multisite fungicides were recommended to extend active ingredient life.
The T2 timing for wheat, particularly “rubbish wheat” cases, generated 24 contributions focusing on effective fungicide mixes and balancing disease control versus cost. Users sought cheaper but efficacious alternatives given dry conditions impacting disease pressure. Substitutions such as folpet and adjustments to spray regimes were debated to combat ramularia and net blotch.
The Univoq growth regulator conversation (23 contributions) complemented fungicide discussions, with members sharing trial results and observations on timing for optimising crop standing power and yield. Despite some scepticism, many reported favourable outcomes in terms of lodging reduction and yield stability.

Crop and Machinery Management
The linseed harvest debate (22 contributions) highlighted practical challenges with combine headers. Growers discussed varietal-specific threshing demands, moisture management, and header configuration tweaks to reduce losses and improve throughput. The need for tailored machinery setups to accommodate linseed’s unique characteristics was stressed.
Alternative herbicide options for winter barley beyond Axial (16 contributions) attracted interest from those facing resistance or control gaps. Several alternative products and integrated approaches were proposed, though a consensus on a direct substitute is yet to emerge.
For brassica growers, especially Cavolo Nero (15 contributions), discussions covered disease control protocols and cultural practices to maximize quality. Questions around seed selections and pest management were also present.
The glyphosate application debate (18 contributions) illuminated caution on spraying at temperatures above 25°C, with users sharing experiences of leaf scorch and efficacy concerns. Many recommended altering spray timing or considering alternative herbicides under warm conditions.

Additional Topics of Interest
- Soil amendment comparisons such as Calcifert versus ground limestone saw a smaller but focused conversation, with members exchanging rates and timing recommendations to address pH issues in acidic soils.
- Fertiliser tank design and management was discussed with a dozen contributions focusing on ergonomics, corrosion issues, and mixing strategies to ensure product integrity.
- Queries regarding spreading muck before discing fields offered practical tips on nutrient incorporation and minimising odour or nutrient loss.
- Several contributions addressed harvesting logistics and crop storage concerns, including moisture management and marketing strategies ahead of the 2026 season.

Conclusion
This week’s Arable discussions on The Farming Forum have underscored the complexity and variability in fertiliser management amid fluctuating prices and evolving product availability. Growers demonstrated a clear preference for precise, cost-effective applications tailored to their farm size and conditions, balancing the pros and cons of solid and liquid fertilisers. Meanwhile, fungicide stewardship, especially for spring barley and wheat, remains a top priority given resistance risks and budget constraints. Machinery adaptation for specialty crops like linseed reflects ongoing efforts to optimize harvest efficiency. Overall, the community is actively exchanging valuable knowledge, providing a robust support network as growers navigate the critical early season crop management decisions.
