Project Description


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).
Measurements in field experiments include: initial soil fertility status, crop phenology, yield components, grain quality, grain yield, dry matter accumulation and nutrient removal in the harvested and unharvested portion of crop.
