The results show that, the animal dung samples: cow, donkey, goat and sheep have common physical properties. Similarly, it appeared that the house-refuse and ani-cro-ber (combination of all materials) have the same physical properties. Leaf samples (Acacia nilotica and Acacia. albida) are types of organic materials, which show some similarities in their textural appearances but differed significantly in term of structure. Millet husk, wood ash and wood husk show unique physical properties. However, it is reported that nitrogen content for all the animal materials is above 2% but show a practical variation in term of phosphorus, potassium, calcium, and magnesium. Ani-cro-ber has the highest nitrogen content of 3.07% while wood-husk has very low content (0.98%). There is high potassium content in Acacia nilotica (2.01%), Acacia albida (1.87%) and ani-cro-ber (1.82%). Generally, with the exception of ani-cro-ber that has phosphorus content of 1.04%, all the remaining organic materials show low phosphorus contain of less than 1%. Calcium is high in ani-cro-ber (17.9%), wood ash (17.6%), and wood husk (16.3%), but very low in sheep dung (0.13%), cow dung (0.16%), millet husk (0.20%), goat dung (0.21%) and donkey dung (0.29%). Also, calcium is high in ani-cro-ber (5.39%), wood husk (4.11%), wood-ash (3.23%), and millet husk (2.88%). This finding suggests that organic materials should be widely used as good sources of essential soil nutrients and soil quality and soil fertility rehabilitations; and this is particularly important under poor soil condition.&#13;
