Dragon fruit agriculture on soil geomorphology perspective

Abstract

This study aims to describe the land horizon of soil texture that is influenced by soil moisture, soil pH, soil organic matter and soil color in dragon fruit gardens in the Kemuning Lor village, Arjasa Subdistrict, Jember Regency. The type of research used includes qualitative research using the survey method. The object of this research can be obtained and reviewed from the Geomorphological and Geological Map of the Arjasa Subdistrict, Kabupaten Jember, East Java Province on a scale of 1: 25,000 (Indonesian Digital topographic map), which is on the condition of the land horizon. Point samples are determined by the area of the dragon fruit orchard selected to be used as five sample points by means of tools, namely, google earth, GPS, pH and humidity measuring devices, geological maps, and geomorphological maps. The results showed that the 5 points taken at the dragon fruit garden had an average pH that was neutral, the soil moisture was high, the soil was of average dark brown and blackish brown, brown in such a way that the condition of organic matter was present in O horror or the uppermost layer itself has a fairly high level of soil fertility, the soil structure that is there contains quite a lot of sand and clay. These conditions influenced by old volcanic landform, aluvial plain, and quarter volcanic landform
