KAJIAN SIFAT FISIK DAN KIMIA TANAH PADA TANAH YANG DI TANAMI PADI GOGO (Oryza Sativa) DI DESA WAWONA KABUPATEN MINAHASA SELATAN

Abstract

ABSTRACT
This study aims to determine the physical and chemical properties of soil on soil that planted
upland rice in Wawona Minahasa Selatan Village. This study was taken samples on soil that was planted
with upland rice and land that is not planted in upland rice. This research was conducted by using survey
method with composite sampling technique in Wawona Minahasa Tenggara Village at two locations
planted and not planted with upland rice then under the soil sample to soil laboratory of Faculty of
Agriculture Unsrat for analysis of texture, permeability, soil pH, C -organic, N-total, K-available, and
Phosphorus. This study found the physical properties of the soil texture of the soil in the village of
Wawona at the location of the planted and not planted with gogo rice has the same texture class clay
berliat. The permeability of soil at the location of planted upland rice was 7.48 cm / h - 8.98 cm / h while
in the unopested areas 7.23 cm / h-7.73 cm / hr. The soil chemistry properties are: soil pH at planted site
and not planted with upland rice pH value 6,78-6,80 with neutral criterion, C-organic at planted location
and not planted with upland rice have the same criterion that is being (2 , 08% -2.39%), soil nitrogen in
the planted site has low criterion (0.16% -0.17%) and at the unfertilized site has medium criterion (0.22%
-0.24%) . Potassium in the planted and unlogged areas of upland rice has the same criteria that is very
low where in the cultivated tilapia criteria (0.068 me / 100g-0.076 me / g) and the unplanted location has
the criterion (0.078 m / 100g-0.083 M / g).(15,46%) and in non-cultivated land have low criterion (11,56
Ppm-12.81 ppm).
Keywords of physical and chemical properties.
