| Abstract | ||||
| Lack of adequate nutrient supply and poor soil structure are the principal constraints to crop production under low input agriculture systems of Dakhalia Governorate. The burning of crop residues is one of national problems in Egypt especially after harvesting or threshing operations to the different crops. The distinctive feature of rice straw is that its silicon content of 4.53% is higher than that in wheat straw of 1.28% and it may be much more difficult to process the rice straw (Su et al., 2002) . Animal compost, organic fertilizer and straw management are among the factors affecting soil fertility in organic cropping systems. However, few studies have compared the effects of organic amendments on soil fertility of organic paddy fields. We conducted a survey of organic farmers’ paddy fields to compare soil nutrients (N, P, K, Ca and Mg), nutrient budgets and partial factor productivity of N (PFPN), and to relate them to organic amendments. This research concentrated on the possibility of using the burring amount of rice straw in Dakhahlia Governorate as field residue. And it will be a good deal situ to dig it through tillage operation to convert it as soil manure. | ||||
