abstract:
Contents of dry matter and macroelements in natural fertilizers – manure, poultry dung, dungstead, and liquid manure – were assessed in a study in the Lublin region in 2007-2008. Content of dry matter in the fertilizers was strongly related to the kind of fertilizer and amounted to, on average, 46.1 in manure, 50.9 in poultry dung, and 3.6% in liquid manure. Average content of nitrogen (N) in fresh manure was 1.03, 1.40 in poultry dung, 0.45 in liquid manure, and 0.42% of fresh matter in dungstead. Average content of phosphorus (P) in fresh manure was 0.35, 0.51 in poultry dung, 0.09 in liquid manure, and 0.03% of fresh matter in dungstead. Average content of potassium (K) in fresh manure was 1.00, 0.96 in poultry dung, 0.24 in liquid manure, and 0.38% of fresh matter in dungstead. Average content of calcium (Ca) in fresh manure was 0.51, 0.70 in poultry dung, 0.11 in liquid manure, and 0.03% of fresh matter in dungstead. Average content of magnesium (Mg) in fresh manure was 0.19, 0.26 in poultry dung, 0.20 in, liquid manure and 0.007% of fresh matter in dungstead. Out of all the macroelements studied, contents of nitrogen and potassium depended the most on the content of dry matter in manure, and on the content of phophorus in poultry dung.
