How much does it cost to test food components in natural fertilizers?
Most often for natural fertilizers we take the average of food components. Of course, this is to a large degree of value quite well estimated, however, precise determination of the composition of bran is possible only by performing laboratory analysis. Such analysis can be conducted at district chemical – agricultural stations. A the results of these studies give very large knowledge about the composition of fertilizer, and this enables how to most optimize fertilization. The more so, because the composition of fertilizer is affected by a wide spectrum of factors -from the method of storage, through the period in which the food is stored, and through the conditions in which it is distributed (this is particularly important in the context of the note).
Testing a sample for the content of general nitrogen, phosphorus and potassium costs 187.47 £. Check the content of these macronutrients can also be in diagnosis and diagnosis – then the cost of testing is 143.73 £ and 151.23 £, respectively. Extending this analysis to the value of Mg we will pay 199.97 £ in the case of manure and 156 and 163 £ by examining gnores or gnores.
Available are also packages in which you can additionally check the content of calcium in tested natural fertilizer (cost analysis of manure in such package is £206 ).
In cases of manure each time is tested also the weight of the actual fertilizer.
How to take a sample of manure, so that it would be authoritative?
The number of samples depends – for example, in the case of manure -on the surface of fertilizer on the prism or platform of manure, which you want to test. Distinguish there may be a primary and general sample. Primary concerns a specific place on a surface or prism, general includes on the other hand a sample created as a result of mixing primary samples. I this is the generic sample, consisting of different intakes at some locations, is the sample that is delivered to the laboratory.
Remember also about that, that the sample should not be taken from the surface layer of bork. This is also applies underneath. Preferably cut off the surface of debris and such separated fragment in packaging (it
should be a tight container or sack of plastic ). Same sample.Laboratory should have about
2 kg weight.
Sample should be appropriately labeled. It should clearly specify the type
of manure (mixed, beef, pig etc.). It should also contain including the following. information in
what way the manure is stored. Also remember, to as quickest after
collection deliver it to examination. During the time from collection to delivery it should be stored in a
cool place.
