The article examines the preconditions for the use of local biological resources in farming agriculture of the North Kazakhstan Region. Wild land reclamation in the central and southern regions has resulted in enhanced extensive nature of farming agriculture in the region which is due to the low agronomic standards and difficult soil and climatic conditions. An increased share of soil-depleting crops in the post-Soviet period aggravated both arable soils dehumification and excessive nutrients removal. Using the statistics provided by the Department of Agriculture and Land Relations, statistical analysis method and generally accepted procedures we have determined the annual volumes of bedding manure, poultry droppings and straw. In addition, we have analyzed the reserves of local agronomic ore, i.e. sapropel, which is the most valuable multicomponent organic raw material with long-term effect. It has been established that the volume of generated biological resources to be used as fertilizers exceeds 17 million tons which can potentially replenish the annual removal of 15% of humus, 39% of nitrogen, 53% of phosphorus, and 57% of potassium taken from fields with harvested crops and erosion products.
