ABSTRACT The efficiency and suitability of different models to estimate infiltration rates in Ferralic Arenosols and Rhodic Ferralsols in southern Brazil are evaluated in this paper. The influence of nine types of land use and soil management practices on infiltration modeling is also assessed. Model parameterization was performed fitting 42 experimental infiltration curves obtained by in situ tests with a double-ring infiltrometer. Soil characterization was also performed in laboratory. The results were assessed using basic statistical descriptors and model accuracy indicators (Nash and Sutcliffe efficiency coefficient and root mean square error). The investigated models satisfactorily simulated the infiltration rates and the most accurate model was modified Kostiakov, followed by the Horton; Singh and Yu; modified Holtan; Holtan; Philip; Green and Ampt/Mein and Larson and Kostiakov. Different types of land uses and soil management practices significantly affect the infiltration rates, mainly those combination with great presence of macroporosity that resulted in an erratic infiltration behavior and affected the infiltration model accuracy.

When olive groves are cultivated on clayey soils with steep gradients, as in many Mediterranean areas, reducing the runoff and soil erosion rates by adopting proper soil management practices is imperative. A soil cover by pruning residues may represent an alternative to the commonly adopted mechanical tillage. This study evaluates the water infiltration rates and surface runoff volumes in a steep and clayey olive grove of Southern Italy. These hydrological variables are measured at the plot scale under four soil management practices (mechanical tillage, total artificial protection of soil and soil cover with two different rates of vegetal residues). The measurements have been carried out using a rainfall simulator under dry (undisturbed) and wet (that is, on soils disturbed by intense rainfall) conditions. The mechanical tillage leads to lower water infiltration rates and higher runoff production. The retention of a soil cover by vegetal residues (in the range 3.5–17.5 tons/ha of dry matter) reduces the runoff rate on average by 30%, mainly because of the increased soil infiltration rates (over 100%, compared to mechanical tillage). After soil disturbance due to antecedent rainfall, the runoff generation capacity of a soil disturbed by a heavy precipitation significantly increased compared to undisturbed soils because of the decrease in soil infiltration rates. Overall, the retention of vegetal residues over the soil may be advisable to reduce surface runoff generation rates, particularly for saturated soils.

Information on soil changes under various forms of land use in poplar box (Eucalyptus populnea) lands on solodic soils is summarized and generalizations on the effects of management practices on the soil resource are made. The implications of the results for land use are considered and problems seen as requiring further research are outlined. Crazing by domestic livestock results in soil compaction which, through decreasing the infiltration rates, causes an increase in the surface run-off of water. These effects are enhanced by the killing of trees, and the associated changes in soil water content profiles are accompanied by changes in the distribution of soluble soil salts. Scalds develop in some areas. Tnese deleterious changes are reversed where there is shrub growth and livestock are excluded. The reasons for the development and persistence of scalds require further elucidation. In particular, the conditions requited for the recruitment of grass and shrub species, and the relative importance of the various pathways for salt movement in these systems, should be defined.

Some topsoil physical properties evolve unfavourably under continuous, no-till farming. On the Pampa, loam soils under no-till sometimes have lower infiltration rates than those conventionally tilled; this is due to the occurrence of platy and massive structures. In this study, we aimed to identify the soil management practices that promote platy structure formation, and explain the soil physical behaviour linked to the thickness of platy structures in relation to infiltration rate, bulk density and shear strength. Six fields with different numbers of years under agriculture and diverse previous crops (maize or wheat–soybean double crop) were sampled, distinguishing within each field headlands (areas with higher traffic) and centre (lower traffic). Twenty samples were taken at random along a 200-m transect to characterise soil structure (platy, granular or massive) and the thickness of the platy structure. Principal component analysis revealed linkages between previous crop and location in each field and type of structure. ANOVA showed a significant (P < 0.05) interaction of previous crop × location. The frequency and thickness of the platy structures were lower, and those of granular structures higher, under wheat–soybean double cropping and in the centre of the field. Greater thickness of the platy structure determined lower water infiltration rate (r = –0.337; P < 0.01) and greater soil shear strength (r = 0.297, P < 0.01). Micromorphological analysis indicated the dominance of massive and platy structure in the headlands and bioturbation in the centre of the fields with wheat–soybean double cropping. These results suggest bioturbation, crop-root binding and low machinery traffic as the main factors minimising soil evolution towards unfavourable structural types under no-till farming in the area.

The UN Sustainable Development Goals (SDGs) identify the need to restore degraded soils in order to improve productivity and the provision of ecosystem services. The aim is to support food production, store and supply clean water, conserve biodiversity, sequester carbon, and improve soil resilience in a context of climate change. Within this framework, in order to achieve the SDGs and to correct land management in the long-term, soil management is considered mandatory. The reduction of land degradation should be based on various sustainable soil management practices that improve and maintain soil organic matter levels, increase water infiltration, and improve soil water management. This technical review - a policy paper - summarizes the sustainable and territorial impact of soil degradation, including soil water erosion, from the global level to the European and National levels. Furthermore, with the aim of sharing ongoing soil and water management actions, instruments, and initiatives, we provide information on soil and water conservation activities and prospects in Italy.

Long Term Effect

SUMMARYThis experiment was conducted to study the long-term effect of soil management treatments on crop yields, sustainability yield indices (SYI) and soil fertility in rainfed semi-arid tropical Alfisol at Hayathnagar Research Farm, Hyderabad, India, during the period 1995 to 2009. The experiment was conducted in a split–split plot design with conventional tillage (CT) and minimum tillage (MT) as main factors, surface application of sorghum stover @ 2 t ha−1 (SS), fresh Gliricidia loppings @ 2 t ha−1 (GL) and ‘no’ residue (NR) as sub-factors and levels of N viz. 0 (N0), 30 (N30), 60 (N60) and 90 (N90) kg N ha−1 as sub–sub factors in a castor–sorghum two-year rotation. On an average, CT maintained 30.4 and 57.0% higher grain yields of sorghum and castor, respectively, over MT. Between two residues, GL performed well in both the crops. The highest yields of sorghum (1425 kg ha−1) and castor (876 kg ha−1) were recorded at 90 kg N ha−1. CT maintained higher SYI of 0.44 compared to MT (0.38) and higher agronomic efficiency (AE) of 13.5 and 6.76 kg grain kg−1 N for sorghum and castor crop, respectively. Use of crop residue as mulch had an advantage in increasing the yield of both the crops with increase in rainfall under CT even without N application (control), probably by making the soil more receptive to water infiltration, better moisture storage and by reducing the evaporative losses. Using response functions, the optimum fertilizer N requirement was also computed for a given set of tillage and residue combinations. The revised optimum fertilizer N doses for sorghum and castor varied from 45 to 56 kg ha−1 and 46 to 74 kg ha−1, respectively, under different tillage and residue combinations and could be recommended depending upon the soil management practices.

AbstractIn the high Andes, environmental and socio-economic drivers are transforming land use and presumably affecting thein situconservation of potato (Solanumspp.). To monitor the use and conservation of intraspecific diversity, systematic and comparative studies across land-use systems are needed. We investigated the spatial-temporal dynamics of potato in two contrasting landscapes of Peru’s central Andes: a highland plateau (Huancavelica) vs. an eastern slope (Pasco). We examined household-level areal allocations, altitudinal distribution, sectoral fallowing practices, and the conservation status for three main cultivar groups: (i) bred varieties, (ii) floury landraces, and (iii) bitter landraces. Mixed methods were used to survey 323 households and the 1,101 potato fields they managed in 2012–2013. We compared the contemporary altitudinal distribution of landraces with 1975–1985 altimeter genebank data from the International Potato Center. We show that intensification occurs in each landscape through adaptations of traditional management practices while maintaining high intraspecific diversity. Access to land and production end use (sale vs. consumption) significantly affected smallholder management and differentiated the landscapes. Total areas in Huancavelica and Pasco were allocated to 82.9% vs. 74.2% floury landraces, 9.2% vs. 25.7% bred varieties, and 7.9% vs. 0.1% bitter landraces. In market-oriented Pasco, fields in sectoral fallows between 3,901 m and 4,116 m above sea level consistently contained the highest levels of landrace diversity. The bulk of diversity in subsistence-oriented Huancavelica occurred between 3,909 m and 4,324 m outside sectoral fallows. Most of the unique landraces documented were scarce across households: 45.4% and 61.7% respectively in Huancavelica and Pasco. Bred varieties showed the widest (1,100 m) and bitter landraces the narrowest (400 m) altitudinal distributions. Potato cultivation has moved upward by an average of 306 m since 1975. Landrace diversity is versatile but unevenly distributed across landscapes. This requires adaptive ways to incentivizein situconservation.

Soc Stocks

An abundance of soil organic carbon (SOC) generally enhances the quality of lands for agriculture or forestry. Concentration of SOC varies in accordance to the type of land use, the inputs to the soil, and natural factors including climate and vegetation. SOC is vital for sustaining agricultural productivity which chiefly depends on both the inherent soil type and crop management practices affecting depletion or replenishment of organic matter over the years. Assessment of SOC concentration is a characteristic measurement of evaluating soil quality and the carbon sequestration potential of agricultural land. This study aims to assess SOC distribution on selected farmlands of Nepal’s mid-hills, where farmers have adopted sustainable soil management practices in non-irrigable hill terraces (“Bari” land) in comparison with those of surrounding Bari and forests where no such interventions are made. Thus the present study estimated SOC content of three types of land use – farmland with sustainable soil management practices (SSMP), farmland without sustainable management practices (Non-SSMP) and the community managed forest in four mountain districts of Nepal, namely Baglung, Dhading, Kavre and Okhaldhunga. This study found the average SOC stocks in the SSMP land in the range of 20 - 44 Mgha-1,those in non-SSMP agricultural areas 15 to 48 Mgha-1, and in the forested land 16 to 23 Mgha-1. In general, the abundance of SOC stocks are in the order of SSM>Non-SSM>Forests. The analysis indicates the high potential for carbon sequestration in hill agriculture lands through sustainable soil management.
