Fertilisation in Eucalyptus grandis on Severely Truncated Soil. III: Nutrient Uptake


     

   Subscribe/Renew Journal


Nutrient content and uptake by different components (ischolar_main stem, twig and leaf) of one year old Eucalyptus grandis as affected by urea and superphosphate application at Minmutti, Kerala was estimated. In general, N, and K concentration decreased due to N and P fertiliser application either alone or in combination. However, uptake of N, P and K increased with each dose of application of N and P fertilisers and generally uptake values were maximum in N75 P75 treatments. Percent recovery of N was greater (79.1%) in N75 P75 treatment and P recovery (18.8%) In N75 P75 treatment.

Abstract


Nutrient content and uptake by different components (ischolar_main stem, twig and leaf) of one year old Eucalyptus grandis as affected by urea and superphosphate application at Minmutti, Kerala was estimated. In general, N, and K concentration decreased due to N and P fertiliser application either alone or in combination. However, uptake of N, P and K increased with each dose of application of N and P fertilisers and generally uptake values were maximum in N75 P75 treatments. Percent recovery of N was greater (79.1%) in N75 P75 treatment and P recovery (18.8%) In N75 P75 treatment.
