“…Final suitability layer in form of thematic map is shown in Figure 3. Possible suitability values match standardization interval [1][2][3][4][5], with mean suitability value of 2.86 and standard deviation of 0.37. Suitability values range from 1.78 to 4.10, which indicates that no part of the study area fully satisfies the selected criteria.…”

Spatial and environmental conditions on the agricultural land are invariable components and any plantation planning should take them into consideration. The conducted research presented methodology for suitability calculation of hazel plantations based on multicriteria analysis, performed in Vukovar-Srijem County. Nine criteria representing topographic, climate, pedology and infrastructure properties were modelled in GIS environment. Values of created layers were standardized using stepwise standardization and their respective weights were calculated by Analytical Hierarchical Process. These values were integrated using weighted linear combination, resulting with suitability values. The surrounding area of the City of Ilok had the highest suitability for hazel plantation in the studied locality, with maximum suitability 4.1 out of 5.0. Suitability was visualized on a thematic map, which enables farmers to interpret the data.

“…Multicriteria analysis in agriculture is currently not developed as a recognizable procedure for calculation of land suitability in Croatia. However, variants of spatial modelling for suitability estimation in agriculture were used extensively in the eastern Croatia during the last decade (Vukadinović et al, 2011;Bogunović et al, 2016).…”

“…Several studies have shown the capabilities that penetrometers have to spatially distinguish variations in mechanical properties in soils [ 20 ]. Soil resistance strongly depends on its volume, density, texture, structure and organic matter components [ 21 ]. It should be noted that for soil, settlement can change significantly in space depending on land use (fig.…”

The present work involved a study of the impact of tillage on soil resistance using a three-body disc plow hitched to a 60 hp tractor, on soil structure. All plowing was carried out on the same day with this plow on 21 plots, divided into 3 blocks of 7 elementary plots serving as treatments. Treatments are designated P0. P1, P2, P4, P8, P12, and P15 corresponding to plowing frequencies: 0, 2, 4, 8, 12, and 15. The P0 treatment is used as a control. The tests were carried out in accordance with the standards: NF P 94-050.1995, for water content by weight, NF EN 1097-3.1998, for apparent density, and NF EN 1097-6.2001 for porosity. Soil conductivity was determined using the Muntz method. The results show that plowing at a minimum frequency of one or two per cycle provides better soil resistance. Two plowings per cycle gave better soil resistance (20.8 (0.27) bc; 19.6 (0.27) d), water content (0.016 (0.002) b ; 0.015 (0.002) b). Soil hardness and density decrease with increasing water content, while porosity increases with plowing frequency (0.437 (0.017) a to 0.478 (0.017) a). For this type of soil, one or two plowings are more than enough to maintain better soil resistance and water conservation. This work has enabled rural actors, and farm machinery operators in particular, to better carry out tillage operations. Keywords: Agricultural soil, soil tillage, mechanical properties, penetration resistance, Benin Republic.

“…In addition, Medeiros et al (2010) found a similarity between the results obtained using a manual penetrometer and those obtained with the electronic penetrometer when detecting the critical depth of compaction of three types of soil: silty, clayey and sandy. In all cases, penetrometer resistance strongly depends on the soil bulk density, texture, structure and soil organic matter content (Cassel, 1982;Bogunovic et al, 2016). It should also be noted that soil compaction can vary significantly in space depending on land use.…”

“…When these properties exceed critical values, plant growth is severely restricted (Medeiros et al 2010). Several factors influence soil compaction which may include different tillage tools, depth and speed of ploughing, moisture content, texture or soil cover residue (Bogunovic et al 2016). Experimental results studied variations of crop yield as a function of the level of subsidence of the surface horizons (Richard, 2008) but the influence of soil stress on the strength of agricultural equipment has been less studied.…”

The physical properties of soils are important for proper monitoring of soil functions. In order to evaluate soil resistance to agricultural equipment, a study was carried out on the four main soil types (ferralitic, ferruginous, hydromorphic and vertisol) in the eight agroecological zones of Benin. The objective of this work was to determine the physical and mechanical parameters of the soils. A sampling of soil types by agroecological zone was carried out in 36 localities in Benin to record vertical and horizontal soil strengths using a compactometer and a penetrometer. These data were complemented by measurements of texture, density and water content of the soil samples. An analysis of variance, polynomial regressions and Pearson correlation were performed between the parameters studied. It is noted that majority of soils assessed were sandy loam. The high sand content in most soils would be due to the depth considered (20 cm). The bulk densities range from 1.21 to 1.73gcm-3 and water contents from 4.9 to 35.11%. Vertical resistances range from 3.89 to 16.36 kg cm-2 and horizontal resistances from 1.03 to 4.44 kg cm-2. Strong soil resistances (vertical and horizontal) are recorded in the northern part of Benin where large proportions of the gravelswere observed in the samples taken. A positive correlation was observed between vertical resistance and horizontal soil resistance. It can be concluded that soil resistance in Benin vary from one agro-ecological zone to another, but the linking of soil properties is less significant between zones.
