Abstract


ABSTRACT

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