Effect of organic matter application on some of the soil physical properties

Abstract:
In order to investigate the effect of compost, vermicompost and sewage sludge application on some of the soil physical properties, an experiment was carried out in split plot based on complete randomized block design in three replications in the field of the University of Agricultural Sciences and Natural Resources of Sari. Seven levels of fertilizer treatments (T1=control, T2=compost 20 tons per hectare, T3=compost 40 tons per hectare, T4=vermicompost 20 tons per hectare, T5=vermicompost 40 tons per hectare, T6=sewage sludge 20 tons per hectare, T7=sewage sludge 40 tons per hectare) and four levels of fertilizer years, one year fertilizer (1385), two consecutive years fertilizer (1385 and 1386), three consecutive years fertilizer (1385, 1386 and 1387) and four consecutive years fertilizer (1385, 1386, 1387 and 1388), respectively. Physical properties in this study were as, bulk density, particle density, total porosity, water holding capacity, field capacity, permanent wilting poit and available water capacity in soil. The results of the study showed that the application of compost, vermicompost and sewage sludge in soil were significantly effective in increasing the total porosity, water holding capacity, field capacity, permanent wilting point, available water capacity and in decreasing the bulk density and particle density compared to control. Where as, years of consumption of fertilizer did not have a significant effect on the physical properties of the soil except on the amount of FC, PWP and AWC. The interaction between years of consumption of fertilizers were significantly different only in particle density and field capacity.
