Effects Of Land Use

Land-use change has been shown to affect soil quality and may lead to soil degradation. The effects of land-use change from natural forest to tea farming on soil properties and quality were studied within Guilan Province of northern Iran. Thirty-six soil samples (0–30 cm) were randomly collected from six sites with three replications at each site. The soil quality of forest and tea farms was determined using the cumulative rating (CR) index and the Cornell Comprehensive Assessment of Soil Health (CASH) scoring function. Effects of land-use change on soil quality or health were significant (P < 0.01) using both methods. Both methods for all regions (forest and tea fields) showed that forest land-use was more sustainable based on lower CR (lower limitation to crop production) and higher CASH scores (higher soil productivity and quality) than tea farm soils. Both methods were also negatively correlated with each other. Despite pH being a limiting factor for soil quality, it was not influenced by land-use change in most locations because the studied soils were acidic. However, organic carbon was the most important soil quality indicator, which was significantly correlated with soil physical, chemical and biological (respiration rate) properties. Therefore, land-use management practices that are continuously cultivated should include increases in organic carbon.

Water Holding

Soils play a critical role to society as a medium that facilitates crop production and also contributes to the energy and carbon balance of the Earth System. Land-use change and improper land-use is one of the dominant factors affecting soil erosion and nutrient loss in soils. We examined the effects of land-use change on an Elmbrook clay/clay-loam soil on a farm in Ameliasburg on the northern part of Prince Edward County. Three cover types were examined: a sod field (established for over 10 years), a wheat field (part of a wheat/corn/soybean rotation for 30 years) and an undisturbed deciduous forest. Under each land-use type, cores to a depth of 40 cm were collected along three random 30 m transects (at 8, 16 and 24 m), then divided them into 10 cm increments, combining all similar depth increments along one transect. Soil quality was assessed by analyzing various soil physical and chemical properties. Bulk density of the soil was much higher (1.55 vs. 0.95 g/cm3) in both agricultural ecosystems compared to the forest, but only in the 0-10 cm layer. Soil moisture at 60% water holding capacity was much greater for the forest than the sod and wheat soils. Soil pH was slightly lower in the forest compared to the sod and wheat fields. The sod and wheat fields showed losses of ~52% and ~53% organic matter, respectively, in contrast to the forested area. The greatest differences in organic matter and total carbon were found in the top 10 cm, likely due to the greater accumulation of litter at the ground surface in the forest compared to the agricultural sites. It appears that long-term (10 year) agricultural production has led to a decline in some, but not all, soil quality measures, particularly soil organic matter, bulk density and water holding capacity. These findings are consistent with much of the literature concerning the effects of land-use change on soil quality, and highlight the need to develop improved management systems to minimize losses in soil quality that can lead to declines in the productivity potential of soils over time.

Soil quality in an agroecosytem is considerably influenced by land use and management practices. Twenty two potential soil quality indicators were used to assess the effects of five different land use types (arable land, plantation, agroforestry, marginal land and native forest) on soil quality in Akufo and Atan farm settlements in Ibadan, southwestern Nigeria. A total of sixty-two fields were selected from which soil samples were taken at a depth of 0-15 cm and subjected to laboratory analysis. Majority of the evaluated physicochemical properties varied significantly among the land uses and whereas native land performed relatively better for most of the observed attributes, arable and marginal lands performed worse. Due to the moderate to strong significant correlation among the potential indicators, they were subjected to principal component analysis and only seven indicators were selected to compute the soil quality index (SQI). In both Akufo and Atan, native land had the highest SQI (0.8250 and 0.860 respectively) which was significantly different (P = .05) from all the agricultural land uses, except plantation (0.739 and 0.750 respectively). Whereas marginal field in Atan was most degraded (SQI = 0.455), it was closely followed by arable fields in both locations. This study indicates that the current agricultural land use and soil management practices in Akufo and Atan farm settlements have negatively impacted soil quality; however, the degree of degradation was strongly influenced by the concentration of soil organic carbon in the understudied land use systems. It also emphasizes the need to promote the use of sustainable management practices among agricultural land users, so as to increase soil organic carbon stock, and improve soil quality and land productivity.

Abstract. The agricultural Mediterranean areas are dedicated to arable crops (AC), but in the last few decades, a significant number of AC has a land use change (LUC) to olive grove cultivations (OG) and vineyards (V). A field study was conducted to determine the long-term effects (46 yr) of LUC (AC by OG and V) and to determine soil organic carbon (SOC), total nitrogen (TN), C:N ratio and their stratification across the soil entire profile, in Montilla-Moriles denomination of origin (DO), in Calcic-Chromic Luvisols (LVcc/cr), an area under semiarid Mediterranean conditions. The experimental design consisted of studying the LUC on one farm between 1965 and 2011. Originally, only AC was farmed in 1965, but OG and V were farmed up to now (2011). This LUC principally affected the thickness horizon, texture, bulk density, pH, organic matter, organic carbon, total nitrogen and C:N ratio. The LUC had a negative impact in the soil, affecting the SOC and TN stocks. The conversion from AC to V and OG involved the loss of the SOC stock (52.7% and 64.9% to V and OG, respectively) and the loss of the TN stock (42.6% and 38.1% to V and OG, respectively). With respect to the soil quality, the effect was opposite; 46\\,yr after LUC improved the soil quality, increasing the stratification ratio (in V and OG) of SOC, TN and C:N ratio.
