Abstract
A conceptual model for managing productivity of estuary agroameliorative landscapes that makes it possible to take into account the basic parameters of the agroecosystem and the features of the technological process to optimize its operation and to reach a planned level of productivity is presented. The agroecological model that guarantees hay yield at the level of 4–4.5 t/ha is developed for long-term sustainable use of irrigated estuaries with heavy soils. The models are developed for the operation of agroameliorative landscapes and the equations are worked out for correlation dependences of hay yield on the most important factors (contents of humus, phosphorus, and water soluble salts), duration of inundation, and sum of effective air temperatures as applied to the conditions of key segments of estuary irrigation.
