Multisite potassium fertilization effects on sugarcane ratoon yield and economic return in South-Central Brazil

The rate of potassium (K) applied during sugarcane ( Saccharum spp.) ratoon cycles has been reduced due to the K-supply from straw recycling, but it may be insufficient to replace the K export by the stalks and maintain soil K at adequate levels. The aim of this study was to evaluate the multisite r...
