Beberapa Sifat Biologi Tanah Kebun Jeruk Siam (Citrus nobilis Tan) pada Sistem Monokultur dan Tumpangsari dengan Beberapa Tanaman Sayuran di Desa Sekaan Kecamatan Kintamani
Abstract: Some Biological Soil
Properties of Orange Orchard (Citrus nobilis Tan)under Monoculture and
Intercropping System with some Vegetable Cropsin Sekaan Village of Kintamani
Districts. Orange fruit is of economically importantcommodity in Bali. The
fruits mostly produced in Bangli Regency including KintamaniDistrict under
intensified monoculture and intercropping with vegetable crops. Those
systemspredicted contribute to variation of soil biological properties as the
results of differences inmagnitude of agrochemicals that being used. A research
about soil biological properties oforange orchard land was conducted in Sekaan
Village of Kintamani on November 2015 -March 2016. The purpose of the study was
to differenciate the soil biological propertiesamong the common cropping
pattern applied in the study area, namely: monoculture oforange, and either
intercropping of orange with cabbage (Brassica oleracea), tomatoes(Solanum
lycopersicum), chilli (Capsicum annum L.), or cucumber (Cucumis sativus).
Threereplications of rhizosperic soil samples were collected from each planting
systems andproceed for selected soil analysis. The measured parameters were
soil pH, organic-C, as wellas the respective total population number of soil
microorganisms, fungi, Gram (+) and Gram(-) bacteria, and also soil respiration.
The results showed that total population number of soilmicroorganisms and total
fungi were significantly higher on intercropping compare tomonoculture systems.
No significant different of those present among soils that cultivatedwith
different vegetable crops. In contrary, no differences were also observed for
both soilrespiration value and total number of G (+) and G (-) bacteria among
soils differing incropping pattern.
