| Abstract | ||||
| This study was carried out at green house of Soil Science Department, Faculty of Agriculture, Menoufia University, Shebin El-Kom, Egypt to study the effect of different sulphur (S) additives on the chemical properties and the content of available macro-and micronutrients in the compost produced from maize stalks at different composting periods. Four piles of fine maize stalks and farmyard manure with mixed ratio of 65:35 by weight were tested. These piles were treated with S at rates of 0, 1, 2 and 3 % based on the dry weight. The piles were moisted at 60 % WHC of the composted organic materials and aerated every 15 days. Samples of each pile were taken at 0, 20, 40 and 60 days of composting and analyzed for their chemical properties and the content of available macro and micronutrients. The obtained data show that, increasing of both added S and composting period induced a decrease in organic matter (OM) content and pH in the compost, but the content of total N (%) and EC were increased. So, C/N ratios become most narrow in the treatment of 3 % S at 60 days of composting. In addition, the produced compost content of available macronutrients (N, P, K, Ca, Mg and S) and micronutrients (Fe, Zn, Mn and Cu) were augmented with the increase of added S and composting period. These findings mean that, S additives to the composted organic materials improved the compost properties and quality. | ||||
