A field survey was carried out to understand the distribution of soil organic carbon stock and available Zn i.e. DTPA-Zn and organically bound Zn (Org-Zn) from 90 randomly selected rice growing farmers’ fields of Navsari district. Analytical results revealed that all the rice grown soils were ‘clayey’ in texture. Soil pH, EC, CaCO3 content and CEC of soils of entire Navsari district varied respectively from 5.70 to 8.20, 0.02 to 1.82 dS m-1, 0.32 to 6.5 per cent and 32.28 to 70.32 cmol (p+) kg-1. In general, the soils of this district were found neutral in reaction and normal in salinity, except soils from few villages which were moderately alkaline in reaction with slight salinity. Mean SOC stock of Khergam, Vansda, Chikhli, Gandevi, Jalalpore and Navsari taluka was 21.50, 19.94, 19.04, 13.44, 13.22 and 12.10 t ha-1, respectively. DTPA-Zn and Org-Zn in rice soils of Jalalpore, Navsari and Gandevi taluka was recorded low over others. Range of DTPA-Zn and Org-Zn in rice soils of this district were 0.15 to 1.83 ppm (deficient to adequate) and 1.1 to 6.68 ppm, respectively with corresponding mean values of 0.67 and 3.32 ppm. Correlation analysis showed that DTPA-Zn increased with SOC (r = 0.788) and silt+clay (r = 0.237). The fact that the chemistry of Zn in this set of soils appears to be dominated by the most stable fractions offers an explanation for the common notion held that majority of rice grown Navsari soils have low soil Zn test levels which accounts for low Zn bio-availability. Regression equations showed that variation in DTPA-Zn was governed by combined effect of pH, EC, SOC, CaCO3, CEC, clay and silt +clay up to 64.34 per cent wherein the impact of SOC and soil pH were higher.
