Abstract
The long effect of crop rotation practice in irrigated soil will obtain N inputs from legume plant residues as well as non-legume crop residues, organic fertilizers (manure) and or inorganic fertilizers (ammonium nitrate fertilizer). Crop rotation plays an important role in improving soil fertility (chemical, phisic and biology), production, and sustainability of land use. Crop rotation carried out by farmers is determined by the availability of water. The aim of this study was to investigate the soil fertility attributes in field plots after more than 20 years of applying crop rotation in irrigated paddy field. After the harvests of rice crops at 2017, surface soil samples were collected from the plots of each field. Four field of crops rotation were rice-rice-maize (RRM), rice-rice-soybean (RRS), conventional continuous rice (CRC), and organic continuous rice (CRO). Crop rotation resulted in a significant soil texture, bulk density, fresh soil moisture, P&
