Effect of Potassium Chloride Application for Rice, Cotton and Potato in the Irrigated Zone of Kazakhstan
Over the past two decades a sharp deficit of all nutrients, especially K, has been observed in Kazakhstan. Field trial results indicated a strong positive response to KCl for potato and rice, and a modest response for cotton.
Three years after the initiation of the IPNI Global Maize project in southern Russia, a local solution to an Ecological Intensification (EI) management system is proving to be successful model for demonstrating the potential for better yielding and high quality maize and soybean crops compared to th
First results of research project on the improvement of K fertilizer recommendations in intensive cropping systems in Russia
The continuous removal of potassium by crop and the incomplete return of the element with fertilisers lead to a slow but permanent decrease in the content of plant-available potassium in arable soils; its mobility in soil decreases, as well as the capacity of soil to restore the initial content of p

Results from field studies show that optimization of plant nutrition with N, P and K is an important factor in improving both yield and quality of winter wheat grown in Southern Russia. High yield goal-based NPK application resulted in grain yield increases of 87 to 93%. Two methods for calculating
Stavropol Krai is one of the largest grain-growing regions in Russia. However, about 50% of its cereal grain output comes from areas that suffer from season-to-season fl uctuations in yield due to moisture defi cit. Soil and climatic conditions in these drier areas do allow for fairly high cereal
Through an analysis of the effect of soil properties on the accuracy of the Olsen P soil test, a refined method and interpretive scale for available soil P supply was developed for use in alkaline soils.
The major region of grain maize cultivation in Russia is in the South. This article considers both mineral fertilizer use and maize productivity in the region. The agronomic efficiency of fertilizer applied to maize is summarized for two maize growing zones differing in annual rainfall. The profitab
After 1990 the fertilizer consumption declined from almost 11 million t of nutrients (1990) to current 1,9 million t. And in spite of the slight increase during the last 5 years it hardly reaches 15% of the level in 1990. There are many reasons responsible for that fall. First of all the share of
Geographically, the Eastern Europe and Central Asia (EECA) region includes all former Soviet Union republics. The total area of arable land and permanent crops in the region amounts to 204 million ha. Three countries have 87 % of arable land: Russia 60%, Ukraine 16%, and Kazakhstan 11%. Currently, the EECA Program consists of two large regions: Central Russia, and Southern and Eastern Russia. IPNI activity in this region will initially be concentrated in Russia and Ukraine, and in the near future the Program will expand to include Kazakhstan.
