Influence of energy potential of soil amino acids on wheat yield in typical calcisols

Winter wheat in agricultural production is the most common and oldest crop. An accelerated and sustainable increase in grain production is a key problem for agriculture both in Uzbekistan and abroad. “According to the FAO, there are about 1.5 billion hectares of soil suitable for agriculture. Neutral and slightly alkaline soils of subtropical zones with a dry climate make up 8177.1 thousand hectares or 5.46% of the entire land area of the globe. 14.5 million km 2 or 11% of the world's land stock is suitable for production. Over the past 50 years, the area of irrigated land has increased by almost 12%. As a result, the volume of agricultural production increased by 2.5-3 times1”. In this regard, the study of the theoretical foundations for improving the soil-ecological, energy conditions and increasing the fertility of neutral, slightly alkaline gray soils, taking into account the evolution of virgin and irrigated lands, the development of theoretical and practical issues of their improvement is of great importance.
