    The purpose of studies was to determine chemical properties of composts and content of macro- and microelements of butterhead lettuce (Lactuca sativa L.), cultivar Królowa Majowych, from allotment gardens of West Pomeranian Voivodeship. Chemical analysis included pH, content of organic matter, organic carbon, total nitrogen and total sulphur as well as total amount of macro- and microelements. The assessment of lettuce quality was based on macro-and microelement content in leaf dry matter. A characteristic feature of allotment garden compost is a low content of organic matter and a lower level of macroelements, total nitrogen and carbon, in comparison with the composts from mixed municipal wastes. The majority of composts are mature and stable but C : N ratio turned out to be unfavourable. Heavy metal content in these composts was low, except for one sample with an elevated level of lead. The lettuce cultivated on these composts has poor resources of calcium and phosphorus but optimum content of potassium and magnesium. The lettuce leaves contained a high level of sodium and one sample -an elevated amount of lead.
