Abstract

ABSTRACK Soil chemical properties greatly affect the production of banana plants (Musa paradisiaca L). If the banana plant lacks one of the nutrients it needs, it can result in inhibition of growth and production of banana plants. Nutrients Nitrogen, Phosphorus, Potassium are needed by plants for plant growth and production. Nitrogen is needed by plants in the early growth of plants. Phosphorus is needed by plants in the formation of flowers, fruit and seeds. Elemental potassium is needed as a catalyst in accelerating the process of absorption of nutrients from the soil to the plants. This study aims to determine the chemical properties of soil on soil planted with banana plants in Kalasey Dua Village, Mandolang District. From this study, it can be seen that the chemical properties of soil in the village of Kalasey Dua, Mandolang sub-district indicate that the total pH of the soil is in a neutral condition (6.3 ), C-organic has a low to moderate content value (1.35% - 2.40%). ), Nitrogen has a low to moderate content value ( 0.13% - 0.26% ), soil phosphorus has a moderate content value ( 22.12 ppm - 25.34 ppm) and Potassium is available.

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
