Why analysing all year round is important for Irish farmers

Some farmers may say that regular soil and plant tissue analysis is an unnecessary cost. However, with the unpredictable weather conditions we’ve seen over the past few years, it’s become harder than ever to optimise crop nutrition – and going with your instincts or previous advice may no longer be the best option. This is particularly important for Irish farmers due to various environmental schemes.
Collecting the right data can help you make better decisions, improve productivity, use nutrients more efficiently, and plan with confidence. In fact, season-long analysis provides valuable insight into how your soils and crops are performing, helping you fine-tune management, maximise the value of inputs, and improve nitrogen use efficiency (NUE).
Read on to learn why analysing all year round at key points of the season benefits your farming system, what you should be testing and when, and how this information supports both profitability and environmental compliance in Ireland.
Why is analysing all year round important?
Analysing soils and crops at different stages of the season allows you to monitor progress and adjust management plans in time to maintain and improve crop production. Investing in different types of analysis throughout the year helps you to:
- Maintain and improve soil health
Healthy, well-structured soils are the foundation for optimal crop production. Establishing a baseline through soil testing and monitoring changes over time allows you to manage pH and nutrient availability effectively.
Additionally, organic manures and livestock slurries contribute organic matter which improves soil structure and boosts biological activity, increasing nutrient cycling and availability. Analysing these resources helps you make the most of what’s already available on farm, and could even save you money.
- Refine crop nutrition plans
Plant tissue analysis shows how well crops are accessing nutrients. Your results will show whether nutrient supply is balanced and sufficient, allowing corrective action where needed to support crop performance. Combining this with other analyses will enable you to adjust crop nutrition plans if necessary to ensure optimal growth and maximise yields.
- Evaluate farm management systems
Analysis can help assess how cultivation practices, rotations, organic inputs, and nutrient strategies are performing.This informs change and enables remediation plans to be put in place and implemented for long-term improvement.
- Improve resilience to weather and climate pressures
Key indicators like soil organic matter (SOM) and active carbon analysis provide information on your soil’s fertility and resilience. Improving SOM supports better water retention and infiltration rates and nutrient availability. This all helps plants cope with challenging soil conditions, enabling them to thrive both now and in the future.
- Save money
Analysing organic materials (manure and slurry) will help you calculate exactly how much fertiliser you need to apply to ensure your crops have all they need to thrive. Better managing livestock manures and slurries will benefit the whole agronomic system through the nutrients they recycle back reducing the overall need for fertiliser.
- Assess the impact of sustainable farming practices
SOM analysis supports compliance with Ireland’s Nitrates Action Programme (NAP) and contributes to wider sustainability goals under schemes such as ACRES. Additionally, soil carbon baselining and continued testing can help you confirm if soil carbon sequestration objectives are heading in the right direction.
- Protect water and soil resources
Applying nutrients based on what your crops need reduces the risk of nutrient loss through leaching and soil surface runoff, supporting good water quality and long-term soil function.
Overall, analysis throughout the season provides clarity on how your approach to farming and the farming system is performing. It helps you make data-driven decisions that improve both operational and agronomic efficiency, increase farm profitability, and safeguard the environment.
When and what should I be analysing?
Although weather influences when certain farming operations occur each year, the farming calendar provides clear opportunities to gather meaningful data. Planning analysis around these key points ensures results can be acted on when they matter most.
When is the best time to book in samples for analysis?
Ahead of spring applications: manure and slurry analysis
Testing livestock manures and slurries before application is one of the most effective ways to improve nutrient efficiency. The nutrient content of organic materials can vary widely depending on livestock type, storage, handling, and livestock diet.
Analysis allows you to:
- Accurately account for nutrients supplied by organic manures
- Reduce reliance on purchased fertiliser
- Lower overall input costs
- Improve nutrient use efficiency and reduce environmental losses.
Making full use of nutrients already present on farm is increasingly important under Irish nutrient regulations and supports optimal crop production as well as sustainability goals.
During spring growth: plant tissue analysis
Once crops are actively growing and manures/slurries or fertilisers have been applied, plant tissue analysis provides valuable data on nutrient uptake. This step is often overlooked unless visible symptoms appear in the crop, but early testing can identify hidden deficiencies before yield is compromised.
Plant tissue analysis:
- Checks that applied nutrients have reached the crop
- Highlights imbalances or shortages as the crop grows
- Supports timely corrective action to get crops back on track before it’s too late.
Monitoring nutrient status during the season helps ensure crops stay on track to achieve their yield potential.
Between harvest and the start of a new season: soil analysis & CarbonCheck
The period after harvest and before the next crop is established is the ideal time for soil sampling. Before nutrients are applied, soil testing provides a clear picture of baseline fertility.
Standard soil analysis provides information on soil pH to help guide lime requirements, on phosphorus (P), potassium (K), and magnesium (Mg) to assist nutrient planning, and on SOM levels to indicate soil health. Additionally, this data all helps comply with Irish nutrient management regulations.
For growers focused on improving soil health or participating in sustainability and environmental schemes, soil testing can be expanded to include carbon metrics, such as total organic carbon and active carbon. Our CarbonCheck service helps track progress in building SOM and soil carbon, and in improving soil health over time.
Data paints a full picture of your farm
Each type of analysis provides useful information on its own, but investing in a combination of soil, carbon, plant tissue, and manure/slurry data results in a much clearer picture of how your farming system is performing.
This integrated approach:
- Improves nutrient planning efficiency
- Supports compliance with Irish environmental schemes
- Builds resilience into soils and crops
- Reduces unnecessary inputs and costs
…ultimately helping you see in depth how a crop is performing and where issues exist in real time.
With increasing volatility in input prices, tighter nutrient regulations, and more unpredictable weather, having reliable data is more important than ever. Analysis allows you to make informed decisions based on facts instead of assumptions.
