Faced with rising fuel and fertilisers costs, reduced margins and unprecedented extremes of weather, Britain’s farmers are looking more than ever at ways to reduce overheads, improve yield and work more efficiently.

While we don’t profess to have answers to ALL the current problems, for those who have taken steps towards greater self-sufficiency, with less reliance on bought-in feeds and fertilisers, Kelvin Cave’s expertise and comprehensive range of proven products to optimise the production of home-grown forage and cereals, has contributed to mitigating the impact of many of these headline challenges.

From soil improvement to crop preservation, through processing and ensiling minimising losses and maximising long-lasting nutrient value and pallatability, we offer a host of practical and cost-effective solutions. Our science centre includes field studies that illustrate how our approach has helped farmers become more productive, reduce costs and recover from the effects of extreme weather conditions. 




CrimpSafe 300 and CrimpSafe Hi-Dry
CrimpSafe 300 ensures a controlled fermentation and maximum nutrient retention for ensiled, crimped grain above 25% moisture content. And for effective preservation and ensiling of grain below 25% moisture content, use CrimpSafe Hi-Dry.

Propcorn NC Propcorn NC is the proven, non-corrosive, successor of Propcorn. Safer to use, and with 70% less fumes than straight propionic acid, Propcorn NC is suitable for preserving whole, or rolled, grain and pulses with moisture content of up to 25%, in aerobic conditions.

Safesil Pro and Safesil challenge for all forages, dependent on dry matter, will ensure fast efficient fermentation with maximum nutrient and dry matter retention and minimal aerobic stability losses at feedout.

Balesafe for preserving the quality of hay and straw at up to 25% moisture. It will also preserve wrapped haylage at 50-75% dry matter, and is proven to stop the development of yeasts and moulds in its tracks.


Grain Crimping Machines & Dry Grain Roller Mills
Whether you’re a farmer or contractor, and whatever your projected throughput, there is a machine to suit your requirements.

Designed and manufactured in Finland, the home of grain crimping, and available in the UK only through Kelvin Cave Ltd, Murska / Korte grain crimping machines are widely acknowledged as global market leaders.

Their ability to process all cereal grains and pulses either dry (up to 25% moisture) or for crimping and ensiling (from 25 to 45% moisture) sets the benchmark within the farming industry and meets our own exacting standards for engineering excellence.

SilaPactor removes the air from wholecrop, maize and grass silage clamps to ensure a fast, efficient fermentation with minimal losses, while making best use of available clamp space and reducing risk of air penetrating the face during feedout.



Klampclips – Like an extra pair of hands during clamp filling. Manufactured from spring stainless steel and made-to-measure for different clamp wall thicknesses. Available in packs of 25.

Side Sheets – essential to ensure a complete airtight seal. Heavy duty, 150μm, clear plastic in 50-metre rolls and in widths of 4, 5 and 6 metres.

Grain Moisture Meter – The Wile grain moisture meter is the only grain moisture meter that can give readings above 30% with any degree of accuracy. Available exclusively from Kelvin Cave Ltd, the Wile grain moisture meter tests whole grain, and will give accurate readings on all grain from 12% up to 50% moisture.

Hay Moisture Meter – The Wile hay moisture meter is ideal for testing the moisture content of hay and haylage. The dish probe allows moisture levels to be accurately assessed in the field.

SilaSpray Compact – applicator for accurate application of preservatives through your crimper, baler or forager.

O2 Barrier 2in1 – the single sheet which transforms into two. Polyamide vacuum film layer up to 10 times less oxygen-permeable than conventional silage film that reduces time and labour required to seal the clamp.

Farmguard – high-strength, recyclable silage sheeting. Uses advanced seven-layer technology for improved durability and tensile strength, tear  resistance, a high degree of UV protection and easy, lightweight handling. Farmguard’s barrier to oxygen is up to 100 times that of standard silage sheeting.

Silage Safe – the ultimate clamp protection system. With a projected service life of at least 10 years, this strap tensioning system eliminates the need for any other weighting. Its 2-metre modular design allows for quick deployment and removal.

ClampNet – for improved clamp protection. Reduces sheet damage by birds and vermin and the need for complete weight coverage.
