| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk mengetahui kandungan dan distribusi unsur hara kalium pada lahan sawah di Kecamatan Kalibening dan korelasi antara ketersediaan unsur hara K dengan produksi padi sawah di Kecamatan Kalibening, Kabupaten Banjarnegara. Penelitian ini dilakukan dari bulan September sampai November 2014. Metode yang digunakan adalah metode survei tinjau mendalam dengan tingkat ketelitian 1:50.000. Teknik pengambilan sampel dilakukan berdasarkan Peta Satuan Lahan Homogen dengan menumpangsusunkan Peta Administrasi, Peta Jenis Tanah, Peta Kelerengan, dan Peta Penggunaan Lahan. Diperoleh 9 titik sampel dan kemudian dianalisis di laboratorium untuk mengetahui kandungan K total, K tersedia, pH, dan C-organik. Hasil penelitian menunjukkan kandungan K total tertinggi terdapat pada Satuan Lahan Homogen (SLH) LatIII dengan nilai 54 mg/100g dan kandungan K total terendah terdapat pada Satuan Lahan Homogen (SLH) AluV dan LatV dengan nilai 10 mg/100g. Kandungan K tersedia tertinggi pada Satuan Lahan Homgen (SLH) LatIII dengan nilai 0,25 me/100g dan terendah pada AluV dan LatV dengan nilai 0,16 me/100g. pH tanah berkisar dari sangat masam (4,07) sampai agak masam (5,96). Kadar C-organik berkisar dari rendah (1,60%) sampai sangat tinggi (5,90%). Sebaran K total dan K tersedia pada lahan sawah tergolong Rendah (R) dan tidak memiliki korelasi yang nyata terhadap produksi padi tahun 2014. |

| Abtrak (Bhs. Inggris) | The aims of the research were to know the level and the distribution of potassium nutrient on lowland rice at district of Kalibening and correlations between the availability of potassium element with the production of rice at district of Kalibening, Banjarnegara. The research was conducted from September to November 2014. The methodology was used a method survey of deep observation with the level of thoroughness 1: 50.000. Determination of the point of the sample is done by first creating a Homogeneous Land Units Map, which is made by way of overlay administrative map, soil map, land use map and slope map. The potassium content of nutrient elements in soil measured by taking soil samples as much as 9 points of the sample and then analyzed in a laboratory to determine nutrient levels K, pH, and C-organic. Results of the study showed a Homogeneous Land Units has the content of potassium (K) are total highest in Homogeneous Land Units LatIII with 54 mg/100g. The content of potassium (K) lowest total in Homogeneous Land Units LatV and AluV with a value of 10 mg/100g. For the content of potassium (K) are available, the highest levels of available K in Homogeneous Land Units LatIII with 0.25 me/100g and lowest on AluV and LatV with 0.16 me/100g. Range of pH from very acid (4.07) until rather acid (5.96). Level of C-organic from lowest level (1.60 %) until highest level (5.90). Distribution of total K and available K in paddy fields classified Low and did not correlate significantly to rice production in 2014. |
