Manganese deficiency remains one of the most common nutritional challenges facing growers in the UK. It limits early growth and weakens crop structure, which gradually erodes yield potential. Many fields show the same symptoms year after year, especially on lighter land or soils with higher pH. At Fielder, we developed Mn350 to give growers a faster, more effective way to correct deficiencies and protect performance.
Mn350 is a high-strength manganese crop feeder designed to work with the crop. It delivers manganese in a form the plant can absorb quickly, whilst fitting easily into modern spray programmes.
Why manganese matters so much
Manganese plays a central role in photosynthesis and enzyme activity, supporting overall plant health. When levels drop, crops struggle to grow evenly. In cereals, this often shows as interveinal browning on older leaves and slow tiller development. If deficiency persists, yield potential drops, and recovery becomes difficult.
Standard 15% manganese sulphate often fails to solve the issue. Availability remains limited, especially in cold or wet conditions. Bulky IBCs also create storage problems and product waste. Tank mixing can prove awkward, too, which limits flexibility during busy spray periods.
A more effective solution
Mn350 addresses these issues head-on. It delivers over two and a half times the strength of standard manganese sulphate, with far greater availability to the crop. The nitrate-sulphate formulation allows rapid uptake through the leaf, helping crops respond quickly once applied.
This liquid manganese fertiliser comes in easy-to-handle 5 litre cans rather than large IBCs. That change alone reduces waste and improves storage, whilst making recycling simpler. Lower application rates mean you buy only what you need for the job.
How Mn350 works in the crop
Mn350 absorbs quickly once it reaches the leaf. The formulation moves easily within the plant, quickly correcting deficiency. Faster uptake matters, as manganese shortages often hit early when crops establish roots and leaf area.
The inclusion of potassium supports cell strength and overall growth. Added sulphur and nitrogen also play a supporting role during active growth phases. Together, these nutrients help the crop recover faster and maintain momentum through early stress.
Growers often notice a visible improvement within days, as leaves regain colour and growth becomes more even across the crop.
Designed for challenging soils
Certain soils remain more prone to manganese deficiency. Lighter land and high pH fields, especially those with high organic matter, carry a greater risk. Cold, wet conditions also reduce manganese availability in the soil.
Mn350 suits these situations well. Foliar uptake bypasses soil limitations and delivers manganese directly where the crop needs it. Many growers now use Mn350 as part of a preventative approach rather than waiting for symptoms to appear.
Knowing your soils makes all the difference. Where history shows recurring issues, early intervention helps protect yield before losses occur.
Easy to use, easy to mix
Mn350 fits easily into existing spray plans. It mixes cleanly with all plant protection products and other nutrients. This flexibility saves time and reduces complications during busy periods.
The concentrated suspension allows low application rates, which keeps tank loads efficient. Smaller packs also take up less space in the store and reduce handling strain.
From a practical point of view, Mn350 removes several frustrations linked with traditional manganese products.
What results look like in the field
Crops treated with Mn350 show quicker nutrient uptake and stronger early growth. Deficiency symptoms reduce, and plants maintain healthier leaf area during key growth stages. This supports yield potential as the season progresses.
Lower application rates also reduce storage requirements and leftover product. Many growers value the control this gives over purchasing and stock management.
When compared with standard manganese sulphate, Mn350 delivers a faster crop response and improved nutrient efficiency.
Where Mn350 fits best
Mn350 suits a wide range of crops. Growers use it on cereals, root crops, vegetables, maize, top fruit, and amenity grassland. This flexibility makes it a useful tool across mixed rotations.
A crop nutritionist can help fine-tune rates and timings, especially where deficiency risk remains high. Mn350 works well as part of a broader nutrition strategy focused on prevention rather than cure.
A simpler way to manage manganese
Mn350 offers a straightforward answer to a long-standing problem. It delivers more available manganese and works reliably in the tank, whilst also reducing handling issues on the farm. Most importantly, it helps crops maintain growth when manganese levels threaten performance.
If manganese deficiency affects your fields, Mn350 gives you a faster and more reliable option. Speak to us today to see how this manganese crop feeder can fit into your nutrition programme and support healthier crops from the start.
