Development of Soil Fertility Map as a Decision Support Tool for Fertilizer Recommendations in Citrus

Development of a Soil Fertility Map as a Decision Support Tool for Fertilizer Recommendations for Citrus in India, 2012 Citrus is a highly nutrient responsive crop. But it's productivity in India is low due to multiple nutrient deficiencies, caused by generalized fertilizer application. Application of GIS technology in mapping the fertility status of soil and fruit yields has been useful to provide the desired accuracy and effectiveness in fertilizer recommendations.

Development of a Soil Fertility Map as a Decision Support Tool for Fertilizer Recommendations for Citrus in India, 2011 Citrus is one of the most important fruit crops in India. Average yield levels of citrus has remained stagnant over the past two decades. This project aims to break this yield stagnation through estimation of spatial nutrient variability in citrus orchards and use such information to develop site-specific nutrient management (SSNM) strategies.

Development of a Soil Fertility Map as a Decision Support Tool for Fertilizer Recommendations for Citrus in India, 2010. Citrus is the third most important fruit crop in India, after mango and banana. Citrus is grown on 840,000 ha nationally and total production approaches 7. 6 million t. However, national average productivity of citrus has hovered around 7 to 9 t/ha for the last two decades.
