Land Use Types

Information on soil fertility status of acid soil of a particular area as affected by land use type is important for developing sound soil management systems for improved and sustainable agricultural productivity. The main objective of this study was to assess the fertility status and effect of land use change on soil physicochemical properties. In this study, adjacent three land use types, namely, enset-coffee, crop, and grazing land use were considered in four districts (i.e., Bolos Sore, Damot Gale, Damot Sore, and Sodo Zuria) of Wolaita Zone, southern Ethiopia. Soil samples were collected from a depth of 0–20 cm from each land use type of the respective districts for physicochemical analyses. The results showed that land use types significantly affected ( P ≤ 0.05 ) soil properties such as bulk density, available P, exchangeable potassium, exchangeable acidity, exchangeable bases (Na, K, Ca, Mg), exchangeable acidity, and CEC. Besides, soil pH, OC, and TN were influenced significantly ( P ≤ 0.05 ) both by districts and land use types. The very strongly acidic soils were found predominantly in the crop and grazing lands whereas a neutral acidity level was found in the enset-coffee land use type of four districts. In conclusion, the study proves that land use type change within the same geographic setting can affect the severity of soil acidity due to over cultivation and rapid organic matter decomposition. Finally, the study recommends an in-depth study and analysis on the root causes in aggravating soil acidity under crop and grazing land use types.

The Impact

Abstract Changes in soil attributes caused by the conversion of native forest for agricultural use in the Amazon region is an area of research because of current uncertainties regarding land use and occupation processes. These uncertainties are significant for tropical soils. Understanding changes in soil attributes is vital for developing strategies to mitigate greenhouse gas emissions in the Amazon region. The objective of this study was to investigate the impact of land use on soil attribute variability occurring in distinctly Amazonian environments. This study was conducted using five meshes in Southern Amazonas: Forest 1, cassava, sugarcane, Forest 2, and Archeological Dark Earth (ADE). Descriptive statistical, geostatistical, and multivariate analyses were performed on data obtained from local measurements of CO2 emissions and data obtained from physical and chemical analysis of soil layers up to a depth of 20 cm. Most physical, chemical, and biological attributes of the soil were related to land use classifications. The similarity between cultivated and forested areas yielded no evidence of land degradation resulting from land use. Increasing certain physical attributes total porosity (PT), soil moisture (SM), and Macroporosity (Macro) yielded a greater increase in the CO2 efflux for ADE and Amazon forest environments than for cultivated regions.

Soil Physical Characteristics

<p class="Abstract">This study area was used to be covered by teak forest. However, because of the human influences, the land use was changed to rice field, shrubs, dry field, settlement and remaining teak forest. The aimed of this research is to study the soil chemical and physical characteristics as a base in improving its quality.&nbsp; The soil samples were taken from the field at 5 land use types with 4 repetitions. Then, they were analyzed in the laboratory. This research resulted that all areas have the soil acidity of more than 8 and the soil organic content of 2.72 % to 3.69 %, whereas the Nitrogen content varies from 0.2 % to 0.29 %. Furthermore, the Phosphorus content varies from 4.61 mg · L‒1 to 21.07 mg ⋅ L‒1.&nbsp; The available potassium ranges from 0.78 cmol ⋅ kg–1 to 1.99 cmol ⋅ kg–1. The soil physical characteristics of the study area showed that the bulk density varies around 1 Mg ⋅ m–3 and the particle density of 2.13 Mg ⋅ m–3 to 2.27 Mg ⋅ m–3. The porosity also varies from 46.30 % to 60.80 %, whereas the soil permeability ranges widely from 1.4 cm ⋅ h–1 to 25.9 cm ⋅ h–1. In conclusion, the study area has the high soil acidity, relatively high soil organic matter content, low nitrogen, phosphor and potassium, good porosity and relatively bad permeability. To achieve sustainable forest land use, the use of fertilizer is required, also the implementation of soil tillage is recommended to improve the soil physical characteristics.<br></p>
