Four metrics of KUE are discussed: partial factor productivity (PFPK), partial nutrient balance (PNBK), agronomic efficiency (AEK), and recovery efficiency (REK). The chapter also explores genetic modifications to increase KUE by either improving the efficiency of K acquisition from the soil, improving the efficiency with which K is used by the plant to produce harvestable biomass, or both. The chapter also reviews management of K inputs, such as fertilizer form, fertilizer rate, fertilizer placement and application timing, all of which can all affect KUE. Crop management also impacts KUE. Both intra- and interspecic variations in KUE exist, and it may be possible to sequence crops in such a way that species with greater access to non-exchangeable soil K may increase the exchangeable soil K supply and thereby benefit crops with less access to non-exchangeable K.","brand":"Dr Kaushik Majumdar","offers":[{"title":"Default Title","offer_id":48281279758587,"sku":"9781786766557","price":32.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0779\/3917\/9771\/files\/9781786766557.jpg?v=1772486762","url":"https:\/\/indiepubs.com\/products\/advances-in-optimizing-potassium-use-efficiency-in-crop-production-9781786766557","provider":"IndiePubs","version":"1.0","type":"link"}
