    Sharpen Up On Crop Nutrition For 2025

    As we move into 2025 and prepare for planting, think carefully about what you can do to set your soil up for a successful harvest. It should start with soil structure, fertility and nutrition. For me, soil testing is absolutely crucial to making good planting decisions – too much and you are wasting money – […]

    Battling Broadleaf Weeds in Cereals

    We often focus extensively on grassweed control in cereals, but on many farms – particularly where cereals have been grown year on year – many broadleaved weeds are becoming challenging and robbing us of yield and quality. Thankfully there are many options available so rotating chemistry, if not rotating crops, can be part of the […]

    The Role of Soil Health in Crop Protection

    Healthy soils are the foundation of a resilient, high-yielding, and sustainable farming system. But did you know that soil health also plays a critical role in crop protection? A thriving soil ecosystem not only supports plant growth but also creates natural defences against pests and diseases—significantly reducing the need for chemical inputs. Here’s why soil […]

    Introduction to Precision Farming

    Precision farming, also known as precision agriculture, is an agricultural management approach that leverages data-driven technologies like GPS-guided equipment, satellite imagery, and data analytics to optimise crop production through precise input applications. Instead of a “one-size-fits-all” approach, farmers and agronomists can tailor inputs like lime, fertilisers, and pesticides to match the specific needs of each […]

    Impact of Soil Microbiome on Plant Disease Control

    Beneficial soil microorganisms can suppress soil-borne plant diseases through various mechanisms: Antagonism: Some soil microbes act as natural antagonists to plant pathogens. They produce antimicrobial compounds that inhibit the growth and activity of harmful microorganisms. This biocontrol mechanism reduces the incidence and severity of diseases. Competition for Resources: Beneficial microbes compete with pathogens for space […]

    Maize Plant Populations

    For five years we have tested maize plant populations, and every year we find that the existing advice to plant at 45-50,000 plants/ha does not produce the highest yields or the highest margin – or the best weed control. It is very clear that maize plant populations across the country need a fundamental re-think, and […]
