Field tests were carried out on a sandy soil obtained from the sandy area of the south of Sirte, Libya vvith field capacity 4.65 %, vvilting point 2.75 %, available \vater 1.90 %, pH 8.60, electrical conductivity 146 micromhos/cm, total K+ 5.1 ppm and total Ca++ 265 ppm. The addition of peat + chicken manure given in amounts 0.6 kg + 11.5 kg or 0.8 kg + 7.7 kg or 1.0 kg + 3.85 kg per 100 kg soil respectively, increased available water by 0.9 %, elecrical conductivity by 112 micromhos/cm, total K+ by 6.7 ppm, and reduced pH by 0.23 ali changes being statistically singificant in t-tests. The differences betv/een the effects of three dosages were statiscally insignifıcant. Peat given alone in amounts 0.6 kg or, 0.8 kg or 1.0 kg, per 100 kg soil had no eflect on soil properties examined.
