Rice as strategic agricultural crop requires a sufficient, but not excessive, the supply of essential mineral elements for optimal productivity at right time, right amount and right place of application. An insufficient supply of mineral elements required in large quantities and/or mineral elements with low phyto-availability in soils often limits crop production. In many agricultural soils, there is rarely sufficient phyto-available N, P or K to supply enough of these elements for the rapid growth of crop plants during their early growth. The DSW was founded with a mandate to find the right amount, right time and right place of essential mineral supplying (fertilizers) in both intensive and extensive agricultural systems. In addition, in areas where mineral deficiencies occur in animals and/or humans, fertilizers are applied not only to increase crop production but also to increase concentrations of essential mineral elements in edible portions (bio-fortification).
