Abstract

Organic matter can improve soil fertility as well as soil physical and mechanical properties. The objective of this study was to determine the effect of long-term (seven years) incorporation of organic manures (COMPOST, SEWAGE SLUDGE, FARMYARD MANURE) at four application rates (0, 25, 50 and 100 Mg ha-1) and inorganic fertilizer (250kg urea ha-1 and 250 kg ammonium phosphate ha-1) on some soil, physical (organic carbon, texture and bulk density) and consistency limits (plastic limit, LIQUID LIMIT and PLASTICITY INDEX) using a complete randomized block design with three replications. Organic manure application significantly increased ORGANIC CARBON and consistency limits due to high absorbing water capacity of organic matter, but the soil bulk density was decreased. The soil texture and PLASTICITY INDEX were not significantly affected by adding organic manure. Each percent increase in organic matter, the friability index increased by about 3/9%. In fact, with higher friability index, the longer will be the period when soil cultivation is feasible, extending suitable moisture for tillage operations without damaging to soil structure. The result indicated that 100 Mg SEWAGE SLUDGE ha-1 treatment had the best performance in increasing moisture limits for agricultural machinery trafficability and soil tillage. Inorganic fertilizers had no significant effect on improvement of the measured properties. Therefore, organic manuring could be better than inorganic fertilizer for improving soil physical and mechanical properties.
