Historical and ecological aspects of hydro-reclamation research at the Kirov Meadow-Swamp Experimental Station (to the 105th anniversary of the Station's formation)

The article presents the history of the origin and development of hydromodule research at the Kirov Meadow-Swamp Experimental Station, their practical implementation and ecological significance in the development of the principles of a saving, soil-protective and environment-forming system of agriculture on organic soils in the conditions of the North-East of the European part of the Russian Federation. The main object of long-term research is a typical lowland peatland «Gadovskoye», located on the territory of the Kotelnich peat base of the Kirov region. Special attention is paid to the search for the most effective ways to regulate the water regime of drained swamps used in feed production. It has been established that the most operational, efficient and environmentally friendly method is sluicing, when additional moisture is supplied to the root layer from below. The most optimal range of groundwater regime for annual and perennial forage grasses is shown. The correlation dependence of yield on the degree of drainage of peat deposits is presented. A significant contribution to the reclamation science was made by hydromodule studies on the cutover bogs of the Kirov region. The chemical composition of groundwater and waste swamp waters has been studied on the «Gadovskoye», «Zenginskoye», «Bakhtinskoye», «Pishchalskoye» peatlands, and others, the relationship of the water-physical properties and water regime of the residual deposit with food and temperature regimes, as well as with the coefficient of water consumption of plants and the bearing capacity of the soil of cutover bogs has been established. Agroecological monitoring of the developed peatlands, which have been in culture for more than 40−60 years, shows that during the operation of these facilities there is a gradual decrease in their productivity, due to a decrease in the total agricultural background, partial and even complete violation of the hydrological functions of the drainage network. In order not to completely lose these anthropogenic formations from the sphere of cultural nature management, it is necessary, first of all, periodic repairs of the entire drainage system. Further restructuring within the landscape shell will make it possible to construct fundamentally new post-swamp forest-meadow agroecosystems, where other alternative fields to forage production (hunting, forestry activity, berry-officinal, mushroom, etc.) can be provided.
