Soil sampling with basis on the Albrecht method
Taking soil samples the William Albrecht way:
Taking a soil sample determines how good or bad the result of the analysis will be. A correctly taken soil sample delivers a good picture and gives thus also a good recommendation.
Please follow the guidelines given here carefully so that we can provide you with effective recommendations.
Who should take the soil sample:
The sampler should have a knowledge of the current fields so that the samples represent the average of the fields. Sites of old ponds or former hedgerows, former paths and other unrepresentative areas should be avoided.
When can you take samples:
Soil samples can be taken in principle the whole year. You should always try to sample in the same season to get comparability over the years. In field crops an important fertilizing time is autumn, e.g. be sampled after harvest in summer / early autumn. No samples should be taken under the following conditions:
- Within 90 days after application of larger quantities of organic fertilizer, micronutrients, lime.
- Within 6 months after sulfur fertilization> 30 kg S / ha
- In very dry conditions, when there is no growth
- In frost
What do you need:
- A spade or a stainless steel soil sampler
- A bucket
- New plastic bags for the sample. (500g)
- A waterproof pen
Normally, the samples are taken at a depth of up to 20 cm or other depths can be of interest up to processing depth; for grassland, permanent crops or No Till, please talk to your advisor here.
Where should the samples be taken?
Divide your field into sections where the soil conditions are the same, e.g. in soil color, texture, soil type and make sure that the cuts all have the same history, that is, the same crops, processing and fertilizer application have taken place.
Then take 8-10 samples / hectare from each section into a bucket.
- mix the samples well together,
- remove stones, plant remains and other foreign objects, but do not remove earth.
- Fill 500 g of the mixture into the sample bag.
Only use new plastic bags, original sampling bags or food freezer bags (zipper bags), ie no shopping bags, paper bags or similar.
Weigh out the sample taken to exactly 500 g per sample (for example, with a cup) and place in the bag.
Write all the necessary information on the bag with a watertight inscription: your name, sample number. – Do not put any papers in the bag!
For your own reference, we recommend that you document the location on a map or with GPS. Name each sample with a unique name so that you can always safely identify the part where the sample was taken.
Check the following:
- All samples are labeled correctly, with readable writing
- You have documented all samples in your own system with name and location
- The samples are filled to 500 g, not more
- The bags are well closed
- That you have filled out the “Soil sample request form” and enclose it in the package. Send a copy of the form to Mail@levendejord.dk
- Then put the samples in a box and label the package correctly with your information and send to the following address:
NRM Swaffham, Breckland Est.
Downham Road, Swaffham
Norfolk PE37 7QE
