Added Value Fertiliser (worth the extra money or not)

As a business, we try to avoid being too product orientated, but there is a danger that without talking about it you don’t know that we do it. Especially customers who have historically or currently use an enhanced product and are looking for a more cost-effective British made product.

The forage department at CMC are well prepared in conjunction with Humber Palmers to offering advice on a range of Added value fertilisers which enhance the quality of forage produced on farms from silage to maize wheat and barley and especially grazing ground there is a solution for every scenario.

The Humber range incorporates the highest level of cutting edge technology which has migrated across from the amenity sector enhancing both efficiency and quality of the fertilisers.

A unique product

Humber Palmers high-efficiency fertilisers are manufactured from a specially selected range of ingredients to maximize dry matter output, whilst assisting in improving the environment, with their unique efficient phasing properties.

Includes a well-researched vegetable origin organic base, free from any weeds and pathogens, with a high level of humic substances, which assists in the phased release of the fertilisers, available only in the Humber Palmers range.

Added Value to you the customer!!

  • Out-perform the best mineral fertilisers by up to 35% in terms of increased dry matter yield.
  • 25% higher take-up of applied nitrogen, phosphate and potash compared with high-quality mineral fertiliser.
  • Considerably lowers soil and plant nitrate content.
    Imperative when caring for the environment.
    Essential under the Water Directive Rules.
    Increases Trace Element levels.

Trace Elements

A wide spectrum of available Trace Elements is contained in all grades of Humber Palmers benefiting the soil, plants and animals.

These include:

  • Calcium
  • Sodium
  • Boron
  • Iron
  • Zinc
  • Selenium
  • Copper
  • Manganese
  • Cobalt
  • Molybdenum


All grades contain Sulphur, universally acknowledged as essential for amino acid production (cysteine and methionine), – being the catalyst for the improved uptake of applied nitrogen and potash, increasing true protein and reducing nitrate levels in crops and soil reserves.

With levels of atmospheric deposition having declined by over 80% in the last 20 years and continuing to do so, Sulphur is now regarded as the 4th major nutrient for many crops.

Many sectors of UK agriculture, in particular, Grassland, are failing to recognize the importance of Sulphur application with the subsequent loss of fertiliser efficiency and quality production. The use of Humber Palmers will remedy this situation.


A key addition to our OptiGraze product this is added at a rate of 8% which provides 80KG per tonne of product, when spread at 100KG per acre it provides 8 KG of sodium. This is far above fertilisers out there which also contain sodium but at under 1% which when converted back means very little product will make it to the pasture and it’s negligible what actual benefit this brings.

Sodium is vital in sweetening up pastures that suffer from grazing rejection normally associated with dung patches usually on the 3rd of 4th grazing round on a dairy system but not only the dairy farmer will benefit from OptiGraze, sheep farmers will also comment on how well lambs will do on pastures treated with OptiGraze along with beef farmers alike.

In Practice

In March J & S Davey and partners undertook a split field trial of the Humber products in this instance Opticut which is the specialist cutting fertiliser against normal practice and the results are quite impressive

They split a couple fields down the middle at their choosing and the program administered to the fields were as follows

Normal practice

1st cut 2500 Gallons of slurry followed by 100 kg/acre of 38:0:0:19so3

2nd cut 2500 Gallons of slurry followed by 75 kg/acre of 38:0:0:19so3

3rd cut 2500 Gallons of slurry followed by 75 kg/acre of 38:0:0:19so3


1st cut 2500 Gallons of slurry followed by 125kg/acre OptiCut

2nd cut 2500 Gallons of slurry followed by 75 kg/acre of 38:0:0:19so3

3rd cut 2500 Gallons of slurry followed by 75 kg/acre of 38:0:0:19so3

As you can see the only difference was the 1st application of fertiliser and from the below chart you can see the improvement this has made on second and third cuts on fresh samples pre-clamping.
