Abstract

Soil quality is the ability of the soil to function to maintain plant productivity, maintain and maintain water availability and support human activities. The purpose of this study was to determine the Soil Quality Index (SQI) and determine the management direction for improving soil quality on different land uses in the Maginti sub-district. A field study and laboratory analysis were carried out from March to May 2022. The method used in this study was a free survey method through field observations conducted on 2 types of land use, namely irrigated rice fields and dry land. In irrigated rice fields, 3 sample points were taken and 3 sample points in dry land, then composited into 1 sample in order to represent the total amount of each land use. In calculating the value of the soil quality index using the formula by Bajracharya (2006) which has been modified by Ghimire (2018). The soil quality index is analyzed using the indicators that best represent soil functions. The variables observed included Texture, pH, C-Organic, N-Total, P-Available and K-Available. Soil quality index values range from 0-1, the higher the index value, the better the quality. The results of the analysis of the selected soil functions (minimum data set/MDS) and the MDS scoring were summed to determine the value of the soil quality index (SQI). The conclusion of this research is that the criteria for medium soil quality are irrigated rice fields with SQI (0,56) and dry land with low criteria with SQI (0,36). To improve soil quality in irrigated paddy fields and dry lands is to increase organic matter through the application of organic fertilizers with the right dosage according to the type and level of soil fertility.Keywords: Soil Quality Index, Irrigated Rice Fields, Non-Irrigation, Soil Management, Physical Properties of Soil Chemistry.

Abstract

This research was carried out on a clove plantation in Puulemo Village, Lembo District, North Konawe Regency from June to July 2022. The purpose of this study was: to determine the nutrient status of different toposequences on community clove plantation in Puulemo Village, Lembo District, North Konawe Regency. The method used in the field is a survey method based on toposequence. Soil samples were taken by purposive sampling at three points, namely the top, middle and bottom of the slope with a depth of 0-30 cm and 30-60 cm. The samples were brought to the laboratory for analysis of the content of pH, Organic-C, nitrogen nutrients, phosphorus, soil potassium and soil CEC. The results showed that the assessment of some soil chemical properties in clove soil based on toposequences in Puulemo Village, Lembo District, North Konawe Regency, it can be stated that the total-N content in layers 0-30 cm and 30-60 cm were classified as moderate, available-K and available-P were classified as very low, pH values were classified as acidic, organic-C content was classified as very low and CEC content was classified as moderate at the top and bottom. in the middle and bottom at the 0-30 cm layer is classified as moderate while at the 30-60 cm layer it is classified as low.Keywords: Clove plant soil, nutrient status, toposekuen
