Aftermath care

Friday, June 14th, 2013

Now most silages are clamped, attention should turn to the aftermaths. If you wish to graze, aim for 50 units of nitrogen and 30 units of potash. 3,000 gallon per acre of slurry will more than meet the potash requirements, so if applied opt for straight nitrogen to reduce staggers risk.

If the fields are to be utilised for second cut, aim for 75 units of nitrogen and 45 units of potash. If you can avoid grazing these fields, regrowth will be quicker and cleaner. Allowing these fields to be shut off, will help see clamps fill again after last years shortage.

For reliable fertiliser planning it is essential that the nutrient content, rate and time of application of manures are known. The nutrient content of animal excreta is greatly influenced by factors such as diet and water dilution. Slurry nutrient content may vary from one year to the next on the same holding. CARA recommends that the nutrient content of a representative sample be determined by analysis at least once per annum. Interim assessments of slurry can be made by using a slurry hydrometer. CARA are able to provide a lab analysis service, interim assessment via hydrometer and give a report on crop nutrient planning based on results.

CARA slurry/manure analysis = £42 + VAT. Analysis gives levels of Nitrogen, Phosphate, Potash, Magnesium and dry matter. This would allow you to carry out a manure management plan and accurately plan fertiliser requirements. This in turn would:

·improve crop nutrient management

·result in potential savings on fertiliser inputs

·meet farm assurance criteria

·gain environmental agency approval

·benefit the environment
