Abstract


Abstrak. Penelitian ini dilaksanakan untuk mengetahui perubahan sifat fisika dan kimia tanah pada lahan kering akibat perlakuan bahan organik dan kapur dolomit. Metode yang digunakan adalah rancangan acak kelompok (RAK) faktorial dengan 2 (dua) faktor yang terdiri dari kapur dolomit pada taraf 0 ton/ha, 0,8 ton/ha dan 1,6 ton/ha, dan bahan organik pada taraf 0 ton/ha, 6 ton/ha dan 12 ton/ha dengan 3 (tiga) kali pengulangan. Hasil dari penelitian ini menunjukkan bahwa pada perlakuan bahan organik mampu memperbaiki sifat fisika dan kimia tanah dimana stabilitas agregat, porositas total, C-organik dan pori drainase cepat menjadi meningkat serta mampu menurunkan bulk density dibandingkan dengan tanpa perlakuan bahan organik.

CHANGES IN PHYSICAL AND CHEMICAL PROPERTIES OF SOIL ON DRY LAND DUE TO ORGANIC MATERIALS AND DOLOMIT LIME

Abstract. This research was conducted to determine changes in physical and chemical properties of soil on dry land due to the application of organic matter and dolomite lime. This study used  factorial randomized block design (RAK) consisting of 2 (two) factors, namely dolomite lime at levels 0, 0.8 and 1.6 tons/ha, while organic matter at levels 0, 6, and 12 tons/ha. with 3 (three) repetitions. The results showed that the organic matter treatment was able to improve the physical and chemical properties of the soil in which the total porosity, aggregate stability, fast drainage pores and organic C were increased and were able to decrease the bulk density compared to without the addition of organic matter.
