Evaluation of physicochemical properties with the availability of plant nutrients in forests and crop farms in different Fijian provinces

Soils are the foundation of agriculture and forestry it provides many functions such as supply water nutrients anchorage for plant growth more. Forest farming 2 entities ecosystem they may lead to changes in soil properties. To cope with challenges management system, data on current chemical physical properties more necessary. Therefore, we present a comparative study existing forest farms Fiji Island. Soil samples from 24 different locations were collected 8 sites based heterogeneity land use soils, keeping view variation type slope determine physicochemical nutrient status. The bulk density (1.05-1.20 Mg m-3), percent porosity (54.14-56.62), moisture % (16.78-18.53%) permeability (11.79-12.35 cm hour-1 was comparatively higher compared agricultural farms. pH ranged 5.42-6.10 5.30-5.61 respectively. A range CEC found (17.7-19.2) be due amount organic matter comparison results also showed that N, P, K, Ca micronutrients (Cu, Fe, Mn Zn) values low suggests combined good practices, limited agrochemicals minimal disturbance at prevent further degradation, acidification stocks.
