“…In semiarid Mediterranean region, soil quality evaluation under conservation and conventional tillage systems should be prioritized [52] and carbon and nitrogen dynamics modeled under these contrasting systems [53]. These models will be the research focus in near future and for estimating environmental consequences of shifting to No-tillage technologies and conservation cropping sequences in both dry [54] and irrigated systems [55].…”

“…Previous research in the region of Navarre using the SMAF approach for the identification of sensitive SQ indicators showed that particulate organic matter (POM), penetration resistance (PR), aggregate stability and total organic C (SOC) were the most sensitive indicators for evaluating tillage effects associated with rainfed cereal cropping [18]. Our hypothesis for this study was that implementing irrigation would reduce the sensitivity of those indicators because of their strong dependence on the soil organic C cycle [18,40,56].…”

“…Our hypothesis for this study was that implementing irrigation would reduce the sensitivity of those indicators because of their strong dependence on the soil organic C cycle [18,40,56]. The SMAF algorithms developed by [13] are based on soil function so that soil biological, chemical, and physical effects can be examined together and monitored over time.…”

“…We followed a step-wise protocol to: (1) identify the most sensitive SQ indicators as previously in dryland conditions [18]; and then (2) compare the indicators selected under the two conditions; (3) evaluate the overall SQ associated with the irrigated tillage treatments; and (4) determine if the SMAF is an appropriate SQ assessment tool for irrigated Mediterranean conditions.…”

Tillage Effects on Soil Quality after Three Years of Irrigation in Northern Spain

Abstract:Irrigation is being initiated on large areas of traditionally rainfed land to meet increasing global demand for food, feed, fiber and fuel. However, the consequences of this transition on soil quality (SQ) have scarcely been studied. Therefore, after previously identifying the most tillage-sensitive SQ indicators under long-term rainfed conditions, conversion of a research site on a Haplic Calcisol in Navarre, in northeast Spain provided an ideal location to reevaluate those SQ indicators after three years of irrigated management. The Soil Management Assessment Framework (SMAF) was used to test our hypothesis that adopting irrigation could change the sensitivity and importance of non-irrigated SQ indicators. Several soil physical, chemical, and biological indicators along with crop yields were used to evaluate SQ three years after initiating irrigation on a long-term conventional tillage (CT), minimum tillage (MT) and no-tillage (NT) study where either barley (Hordeum vulgare L.) or wheat (Triticum aestivum L.) was being grown. The results confirmed our hypothesis that irrigation would change the relative importance of various SQ indicators and suggested that some SMAF algorithms, such as those used to assess bulk density, needed to be recalibrated for these Mediterranean soils.

“…The labile fractions of the SOC pool are more sensitive to changes in agricultural management practices than is the total SOC (Haynes 2005). These pools can be fractionated by physical, chemical, or biological techniques as indicators of soil quality (Weil et al 2003;Majumder et al 2008;Imaz et al 2010). However, few studies have investigated how SOC pools respond to different agricultural land use types in reclaimed soils (Tian et al 2012).…”

Soil organic carbon plays an important role in soil fertility and carbon sequestration. In the North China Plain, soil nutrients and organic carbon are still lacking in salt-affected soil after a successfully reclamation in the 1980s. Our objectives were to investigate the effects of land use types under different soil management practices on soil fertility, organic carbon pools, and the microbial community at this site. Three land use types were investigated: original land without farming, farmland with residue return, and a vegetable greenhouse with farmyard manure amendment. The carbon stocks were calculated according to the equivalent soil mass method, and microbial community structure was determined by phospholipid fatty acid analysis. Over 30 years, the current concentrations of alkali-hydrolysis nitrogen, available potassium (AK), and available phosphorus increased in the three land use types, except for the AK concentration in farmland, which decreased due to the lack of potassium fertilizer input. The nutrients in the greenhouse were significantly higher than those in the original land and farmland. The carbon stocks in the original land, farmland, and greenhouse were increased by 103%, 179%, and 660%, respectively. Both land use types and seasons influenced particulate organic carbon, chemical-labile organic carbon, and microbial biomass carbon. The microbial community structures were distinctly different between the three land use types. Overall, the soil available nutrients and carbon stocks increased compared to their 1980 levels in the three land use types, and labile carbon pools and microbial community structure exhibited different responses in the three land use types. Compared to spontaneous development, mineral fertilization and organic amendment are more effective for recovering soil fertility in reclaimed soils.
