Qualitative land suitability evaluation for the growth of rice and off-seasons crops as rice based cropping system on paddy fields of central Guilan, Iran

Land suitability evaluation analysis is a necessecary to achieve optimum management and utilization of the available land resources for sustainable agricultural crops production. One of the most serious and urgent constraint in lowland paddy fields of Iran is to improve agricultural land management...
