Sludge, compost, manure

Organic fertilizers such as manure, sludge and compost always contain plant nutrients. However, they may also contain undesirable substances such as heavy metals or pesticide residues. Here is a selection of the analyses we offer for this type of product.

NPK analysis

Total nitrogen, phosphorus and potassium content. The analysis of ammonium nitrogen and nitrate nitrogen complements the analyses above with mineralized or readily available nitrogen.

Elements 16 or 26 pcs

Elements refer to minerals 16 or 26 (ICP-OES). Includes total aluminum, boron, calcium, cadmium, copper, iron, potassium, magnesium, manganese, molybdenum, sodium, nickel, phosphorus, sulphur, silicon, zinc and 26-element addition of arsenic, barium, lead, cobalt, chromium, mercury, selenium, titanium, vanadium and strontium.

Heavy metals

Includes arsenic, lead, cadmium, chromium, copper, mercury, nickel and zinc. Specify if other heavy metals are desired as additions. For analysis according to KRAV, silver is added, while arsenic is removed. (read more about heavy metals in the environment...)

Dry matter content

Dry matter content shows dried weight in relation to fresh weight.

Loss on ignition

Loss on ignition shows the proportion of combustible material in the dry weight.

Pesticides
