“…The geostatistical analysis of soil variability can indicate management alternatives, not only to reduce the effects of variability of soil attributes on agricultural production, but also to increase their response to the various cultural practices employed (Trangmar et al, 1985;Carvalho et al, 2011b;Carvalho et al, 2012). Thus, the collection of spatial values of a given attribute may reveal wide variations because the soil is a product of the action of various factors training varies greatly in its three dimensions, especially the surface (Roque et al, 2008;Montanari et al, 2012).…”

Relations between the yield of bean (Phaseolus vulgaris L.) and chemical attributes of an Acrustox under no-tillage AbstractIn crop year 2006/07, in Selvíria, MS, Brazil, were analyzed the productivity of beans because of the chemical attributes of an Acrustox cultivated under conditions of high technological level of management by no-tillage irrigated with pivot central. The objective was to select, among the attributes studied soil, the one with the best representation to explain the variability of agricultural productivity. Geostatistical grid was installed to collect data from soil and plant, with 117 sampling points in an area of 2,025 m 2 and homogeneous slope of 0.055 m m -1 . From the standpoint of linear and spatial bean yield was respectively explained in terms of P and soil pH. So much for the values of phosphorus (P) in the intermediate layer and subsurface between 24-26 mg dm -3 , as well as for Hydrogen (pH) in the surface layer between 5.0 to 5.4, resulted in sites with the most high yield (2,160-2,665 kg ha -1 ).

The characterization of spatial variability of soil physical and chemical characteristics is very important for precision farming and managing agricultural production. Therefore, the objective of this study was to evaluate the spatial variability of selected physical properties of a soil under different crops in Ado Ekiti, Nigeria using descriptive statistics and geostatistical techniques. Grids of 10 m x 10 m were set up on the field within three land uses. The field was about 3 hectares, out of which 1ha was apportioned for cowpea, 1ha was for sole maize and the rest for maize/cassava intercrop. A total of one hundred and eighty-four (184) georeferenced surface samples were collected for analysis of texture, bulk density (BD), particle density (Pd), porosity (Pt) and saturated hydraulic conductivity (Ks). The study used descriptive statistics to investigate the striking features in each soil property and further adopted semi-variogram and kriged maps to assess the spatial dependence and classification of the soil properties respectively. The soil properties showed varying degrees of spatial variability, with Ks highly variable (118%) than others. There was weak correlation between Ks versus BD (12%) and Pt (-14%) but the correlation was significant with Original Research Article

“…As mentioned above, the main characteristic of the transition from burning sugarcane to green harvest is the retention of sugarcane plant residue on the soil surface [11,12]. The sugarcane plant residue retention is an effective practice to: (i) reduce infiltration and soil loss rates [110]; (ii) protect the soil surface from high temperature ranges [110][111][112]; (iii) maintain the soil moisture levels [110,113]; (iv) increase earthworm populations and soil microbial biomass [110], which are responsible for organic matter decomposition [95,113], increasing carbon stocks in the 0-10-cm topsoil layer [83]; (v) increase soil stability and help spread micro and macroaggregates in the soil, which are important for maintaining the soil microbial diversity through the conservation of their microhabitats [12,98]; and (vi) reduce the necessity of weed control [110].…”

The risks of sugarcane management on soil microbes and their relationships with soil physicochemical factors and biogeochemical processes have not been described from an integrated perspective for different agronomic practices. Here, we provide a platform for multi-analytical interactions between ecologists analyzing the soil microbes at multiple ecological levels and geoscientists measuring the release of greenhouse gases and the physicochemical soil factors including labile fractions from soil organic matter in tropical sugarcane management systems. We compile the benefits and risks of nutrient management and soil amendments as well as of crop residue and harvest management in sugarcane soils on belowground microbial life and biogeochemical processes mediated by soil microbial communities, and we demonstrate that the massive planting of the crop brings environmental risks that include a potential impact on tropical soil ecosystem sustainability. We emphasize that soil management and harvest management are critical for supporting the sustainable development of biofuel production in tropical areas.
