Answer:
The importance of chemical fertilizers in agriculture can not be neglected. However, its extensive and indiscriminate use has created many issues particularly, in the areas where ground water-table is shallow. While, using the chemical fertilizers in shallow water-table areas , one should know about the dynamics of the upward flux from water-table. While, applying, fertilizers, some part of fertilizer remain in the soil column for plant uptake while some move towards ground water in response to the irrigation and rainfall incident; this will increase nutrient concentration in saturated zone (at and below WTD). However, because of capillary rise, this leaching process would be reversed; bringing nutrients back to the root zone. This has both advantage and disadvantage. Advantage is that plants would be able to use maximum fertilizer as returns to the root zone , resultantly produced high yield. The disadvantage is more chances of soil salinity in response to the chemical fertilization. Therefore, under shallow WTDs, for growing a particular crop, reduce the quantity of fertilizer (from recommended dose) equal to how much is there capillary rise from WTD. In this way, the chances of salinity will be minimum.
