Description India has been a traditional producer, consumer and exporter of spices. Almost all states in the country
produce one or other spices. Spices exports have registered substantial growth and crossed one billion
marks in foreign exchange. However, the current productivity levels show a disturbing downward trend.
Besides pests and diseases, important factor contributing to reduced yields in spices is poor soil quality; a
reflection of low carbon sequestration coupled with alarmingly higher nutrient mining from these soils.
Poor nutrient management strategies have resulted in depletion of C reserves, imbalanced' nutrient levels,
and decreased nutrient cycling and processes due to decreased biological activity. Low pH and lower levels
of organic carbon, KI Ca, Mg and Zn are the major constraints iii spice growing soils. This coupled with
high soil erosion and associated nutrient losses in high rainfall growing areas where spices are grown have
further aggravated the problem. Long-term trials on integrated nutrient management (INM) indicated that
fertilizer input efficiency can be increased through rational use of inputs and scientific management.
Adoption of INM techniques will not only enhance crop productivity but will also increase the total
productivity and the efficiency of fertilizer use in these soils. While doing so there is an urgent need to
augment supplies of soil amendments, organic manures, fortified and customized fertilizers supplying
secondary and micronutrients and bioagents to sufficiently support nutrient supply in spice production
systems.
