The study is devoted to developing technologies and methods for harvesting fodder from the forage lands of Kazakhstan in the framework of sustainable management. In the context of climate change, pasture degradation, and the growing need for fodder resources, providing high-quality fodder for the agricultural sector is becoming a key factor in the countrys food security. The paper analyzes the effects of modern organic fertilizers on the condition of rangelands in the Northeastern steppe zone of Kazakhstan. The parameters include the geobotanical composition of pastures, projective coverage, plant density, green and dry mass yields, and the nutritional composition of pasture grass. Bio-organic fertilizers were found to improve each examined indicator. Compared with the control, the application of WUXAL Aminoplant along with organic fertilizer “Kazuglegumus” increased green mass yield to 0.90 t/ha from 0.53 t/ha, dry mass yield to 0.27 t/ha from 0.16 t/ha, and digestible protein content to 0.013 t/ha from 0.007 t/ha. Humate + CO2, along with Stoller Energy, also showed meaningful improvements. The paper concludes that bio-organic fertilizers increase forage yield, protein content, and energy values, specifically when restoring degraded pastures. However, the studys generalizability may be affected by its one-season and one-region limitation. Future research should expand to multi-year trials along with multi-regional trials, in addition to impacting long-term soil health, and also determining economic feasibility. Based on the conducted analysis, recommendations are proposed for improving the current condition of forage lands and ensuring a sustainable supply in the agricultural sector of Kazakhstan.
