Improving N and S Fertilizer Management System under Crop Rotation

Crop response to S-containing fertilizers and various N sources is studied under winter barley – sugar beet – winter wheat – maize rotation.


Location: Krasnodar Krai, Southern Federal District. Objectives: 1) Optimize the rates of S-containing fertilizers (NPKS and NPS). 2) Optimize the N sources for top-dressing in winter barley and winter wheat. Goals: 1) Study the crop response to S-containing fertilizer. 2) Compare Ammonium Nitrate and Urea for topdressing in winter barley and winter wheat. Crop sequence: winter barley (2016-17), sugar beet (2018), winter wheat (2018-19), and maize (2020). Read more

Interpretive Summary


Field experiments with winter barley during the 2016-2017 season were conducted at four agricultural enterprises of AgroGard agroholding, Kuban Branch, located in different districts of Krasnodar Krai. Soils at these locations are Typical and Common Chernozems (Voronic Chernozems Pachic) with moderate organic matter (3. 3 to 4. 3%) and low concentrations of available sulfur (S) (2 to 4 ppm) routinely extracted with 1M potassium chloride (KCl) solution.
