“…Constructing terraces on sloping land can reduce the steepness of the slopes by dividing the slope into smaller, sloping sections. Modified slopes can change hydrological pathways, reduce surface runoff, and increase land catchment areas (Uchida et al, 2013). The use of terraces can increase the moisture content of the soil by improving the soil's infiltration ability and capacity to hold groundwater (Wei et al, 2016).…”

Improper soil management inland with steep slopes is one of the causes of decreased agricultural productivity in hilly areas. The use of terraces on steep slopes is considered effective in preventing erosion. However, this does not increase agricultural productivity significantly. Therefore, this study aimed to analyze the performance of maize on land with and without terraces as affected by the addition of goat manure and NPK. A field experiment was arranged in a randomized complete block design, consisting of 12 experimental plots that were made on a hill with a slope of 79 % with three replications. Plant tissue samples were analyzed for assessing N, P, and K content. However, soil samples were measured for N, P, K, SOC, pH H2O, EC, CEC, and soil texture. Data were analyzed using analysis of variance and continued with a Post-Hoc test (DMRT at α= 5%). The application of manure and NPK fertilizers significantly improved EC, SOC, N, and P in soil, also N and P content in plant tissues. Goat manure played a role in improving soil properties, while NPK fertilizers played a role in supplying nutrient availability directly to plants. The best performance of maize was on land without terraces and cover crops (sweet potato). Competition for nutrients between maize and sweet potato occurred on land with terraces so that the performance of maize tended to be lower. Soil management on land with terraces needs to consider nutrient management and selection of cover crops so that both can increase maize productivity.

“…Magnetic susceptibility, on the other hand, is less widely utilized. Recent years have seen an increase in its use in lab-based applications (for a comprehensive review, see Dalan 2008;Dalan and Banerjee 1998), including provenience studies (Williams-Thorpe et al 2003), relative dating (Ellwood et al 2004;Uchida et al 2013), predicting the success of magnetometer survey (David 1995;Gaffney and Gater 2003), aiding the interpretation of other geophysical datasets (Fassbinder 2015;Gallo et al 2011), investigating feature and site formation processes (Ard et al 2015;Rosendahl et al 2014), and stratigraphic investigations (Dockrill and Gator 1992).…”

Evaluating the archaeological potential of wooded areas is often difficult because many of the techniques archaeologists commonly use to locate and map archaeological sites elsewhere are less effective in the trees. Ground cover hinders the visual identification of surface artifacts during pedestrian survey, and the tree canopy impedes many of the techniques used to map areas of interest, such as optical theodolites and DGPS. Shovel test pitting, which disturbs the integrity of sites and provides limited contextual information, is the most common method used to evaluate woodlots today. In light of increasing interest from Indigenous peoples in limiting the impact of archaeological work on their cultural heritage, we are testing less invasive methods to locate and map archaeological sites within wooded areas. Here, we present the results of a magnetic susceptibility survey on a wooded precontact site in southern Quebec, where the technique rapidly determined site limits and pinpointed the location of several longhouses and other features. Where geological conditions are suitable, this method could considerably reduce the cost and impact of archaeological assessment and investigation of wooded sites by both cultural resource management (CRM) and academic archaeologists.
