Abstract

ABSTRACT Soil  is a natural body that occupies most of the surface of planet Earth.  Soil as a medium for growing plants with various properties possessed. Tomato cultivation is not only on plantation land.  Soil chemistry concerns the composition of minerals, organic matter, and environmental factors. Components of soil chemistry include pH, organic C and essential nutrients. Soil reaction (pH) is a characteristic or parameter that shows acidic conditions in the soil. The taste of tomatoes is sweet - fresh sweetness that can provide freshness to the body. The optimal rainfall for tomato growth is 100-220 mm / rain with the ideal daily temperature, which is 25-30oC. Keywords: Soil Chemical Properties, Tomato Plants

Abstract

ABSTRACTNutrients of nutrients are important factors for plant growth which can belikened to food substances for plants. Plant nutrient contents of N, P, and K in themining area of Talawaan Village was studied in this research. Soil samples from threedifferent places at the mining site were taken and analyzed at the Laboratory ofChemistry and Soil Fertility. Analysis of plant available Nitrogen utilized Kjedhalmethod and plant available P and K used Bray 1 method, The findings show that theplant available nutrient of N, P and K is classified from low to very low, while soil pHof the Talawaan Village Mining area is neutral. It is suggested to increase the nutrientavailability for plants in this location by adding organic fertilizers.Keywords: Plant available nutrients, Nitrogen, Phosphorus and Potassium
