penentuan kadar kalium (k-dd) pada tanah taman agro inovasi di balai pengkajian teknologi pertanian dengan menggunakan metode spektrofotometri serapan atom (SSA)

Abstract

Soil is a layer of the earth's surface that physically functions as a place for growth and development of roots that support the growth of plants and supplies water and air needs, chemically functions as a warehouse and supplier of nutrients or nutrients (simple organic and inorganic compounds and essential elements such as N, P, K, Ca, Mg, S, Cu, Zn, Fe, Mn, B, Cl, etc.), and biologically serves as a habitat for biota (organisms) that actively participate in providing these nutrients. Research has been carried out regarding the determination of potassium (k-dd) levels in agroinnovation garden soils at the agricultural technology study center using atomic absorption spectrophotometry. Research that aims to determine the quality of the soil, whether it is in accordance with the terms and conditions of the Soil Research Agency. From the analysis results obtained potassium levels (k-dd) in Lab codes A, B, C, D, and E are 1.69 me/100g, respectively; 0.89me/100g; 1.08 me/100g; 0.48 me/100g; and 0.56 me/100g with high and very high categories. Based on the data obtained, it shows that the quality requirements of the potassium content in the soil have met the quality standards according to the Soil Research Agency
