JK Senior Frequently Asked Questions


Can J K Senior & Sons reduce my spray costs?

Comparisons between ourselves and the trade have shown 20-25% lower spray costs in our favour. See Annual Spray Costs for more details.

Our involvement with HGCA Crop Bench System has pinpointed machinery and labour as a higher input, endorsing our interest in low input crop establishment i.e. sub soiler drills, Claydon drills and ploughing in with beans.

Should I reduce the rate of Nitrogen with the higher nitrogen cost per tonne?

Yes on cereals if the break-even ratio of 4.0 or more can be calculated. Reduce your N rate by 15-20kg/ha. See RB209

How many points can my consultant give me?

Each arranged meeting is worth 2 CPD points, 1 environment and 1 crop protection. There are only two meetings per year i.e. a maximum of 4 CPD points can be claimed each year of membership, with a maximum of six meetings accredited over the three year period.

Can I reduce the water rate with iodosulfuron + mesosulfuron?

Spraying at 100L/ha covers 30% more ha/day than at 200L/ha - more hectares of Blackgrass hit at the ideal time (2-3 leaf). Droplet concentration will be more concentrated and will have more wetter in it and can lead to a small efficiency increase. Please use flat fan 110, flat fan VP110 or Hawk nozzles.

What is an EAMU?

An EAMU is an Extension of Authorisation for Minor Uses. To use a pesticide product in accordance with an EAMU you must read the text of the EAMU notice before commencing any spray operation.

Tip - only fill in one of the search boxes i.e. only fill in 'Active' or 'Product' then press 'Get Results'.

Can I put manufactured Nitrogen on a frost?

You can apply Nitrogen on a frost providing the land is not frozen for more than twelve hours in the previous twenty-four hours. You must not apply manufactured N fertiliser if the soil is water logged, flooded or snow covered.

Can I put manure on the same site each year?

Temporary storage of solid manure in field heaps need a two year gap before returning to the same site.

Identify the location of field sites on your risk map each year.
