The state program for the effective involvement of agricultural land in the The state program for the effective involvement of agricultural land in the turnover and the development of land reclamation provides for the introduction of 13,234.8 thousand hectares of abandoned agricultural land into the production turnover by 2030. Renewal of their use will solve economic, ecological, social and geopolitical problems. Existing approaches and measures to expand the use of agricultural land are ineffective in the absence of a favorable situation in the agrarian economy. The purpose of the study is to identify the conditions necessary for the involvement of abandoned agricultural land in the turnover. The article considers the economic theories of land rent and effective demand of John. M. Keynes in the framework of solving the problem of involving abandoned agricultural land in the turnover and reducing the transformation of agricultural land into other categories. which in combination with general scientific methods of knowledge and special statistical methods of analysis allowed us to reveal the conditions necessary for this process: the growth of the level of market prices for agricultural products; the growth of land rent, and the growth of land rent due to the increase in market prices for agricultural products should exceed the growth of land rent due to soil productivity. The economic mechanism of creating these conditions is revealed – the excess of demand over supply in the market of agricultural products, which can be organized through direct and indirect support of the population’s demand for food and increase in demand for agricultural products by the state.
