“…Others point out that there was no significant difference in both leaves and roots in terms of tillage (Ojeniyi, 1993). None of the tillage systems had (Ozpinar and Baytekin, 2006). These results are not in agreement with other studies that differences in K due to a more rapid mineralization when chisel had slower mineralization (Hussain et al, 1999).…”

“…However, these results showed that B, Zn and Cu were higher in ST when compared with MT disagreeing Rhoton (2000), while Lavado et al (1999) found higher in plough. Among the micronutrients considered in this study, Zn and Cu were slightly affected by the tillage systems, especially Zn was never higher in MT than other two systems except in roots of 2007 due to low organic matter content in plough (Ozpinar and Baytekin, 2006), as previously reported (Stanislawska-Glubiak. and Korzeniowska, 2009;Houx et al, 2011).…”

“…In this study, Fe could be due to the fact that, during rainfall deficit periods (from May through September), ST and CT improved soil water facilitates and nutrients uptake. Moreover, the soil water availability generally relies on organic matter content which is significantly higher in ST than in MT in an early study of this area (Ozpinar and Baytekin, 2006) (Pais and Benton-Jones, 1997). These results were consistent to other authors (Sękara et al, 2005) who found in maize leaves and roots 0.0095 and 0.0097 g Cu kg 1 , respectively.…”

“…Chemical fertilizer was applied in a band at planting in maize plots at a rate of 50-50-0 kg ha 1 as nitrogen, phosphorus, and potassium (NPK), respectively, according to common practices without K fertilizer in this region. Moreover, plots received green manure from winter vetch (Table 1) which provides between 110 to 200 kg N ha 1 to the following maize concluded by Ozpinar and Baytekin (2006). No chemical fertilizer was used during the growing season due to green manure application from vetch which was suggested by Campiglia et al (2011) in the Mediterranean environment.…”

The effects of tillage on plant availability nutrients are critical to develop nutrient management strategies to optimize yield. The objective of this study was to evaluate differences in the concentration of 19-nutrient and yield after 4-year of conventional (mouldboard plough (MT)) and two reduced (rototiller (ST) and chisel (CT)) tillage systems in maize (Zea mays L.) after winter vetch (Vicia sativa L.) in double crop one year. Three tillage systems were compared from 2005 to 2008 in area located in the western region of Turkey under semi-arid Mediterranean clay-loam soils. Nutrients were determined in maize leaves, stems, roots and soils. Results show that the concentration of macronutrients were found to be higher in leaves and stems of maize than roots in three tillage systems of all years, while the opposite was true for micronutrients. Among the macro and micro nutrients, there was no effect of tillage on nutrient concentration in all maize tissues for sulfur, magnesium, sodium and copper (S, Mg, Na and Cu). Co, Cr, Ni, Pb and Se) were affected by tillage. ST increased N in stems of 2006 compared with other systems. K in roots of 2006 was 52 and 30% greater in CT than in ST and MT, respectively, while ST and MT of 2007 resulted in 38 and 41% greater than CT. In two of four years, ST contributed to higher grain yield compared with other systems. In general, ST can effectively contribute to increase maize yield following winter vetch compared with MT under this region. Results suggested the need for different management systems associated with reduced tillage including rotation, particularly for basic nutrients. Further, results showed similarities and differences with other studies under tillage with maize following winter vetch.

“…Similar results were reported by Sidiras et al (1999), which obtained the highest dry matter yield of common vetch in no-tillage and reduced tillage compared to the conventional tillage. Ozpinar and Baytekin (2006) found that the level of organic carbon in the soil with shallow tillage increased compared to the conventional tillage and to the amount at the beginning of the study. The same authors indicated that at the green forage harvesting, the N content in biomass was higher in conventional than shallow tillage.…”

2 The application of conservative agricultural practices such as crop rotation, shallow tillage, and organic fertilizer could usefully sustain crop yield and increase soil fertility, thus playing an important role in the sustainable agriculture. This study was conducted to determine the effects of conservative agronomic practices on yield and quality of wheat. The effects of these practices on soil fertility were further investigated in this four-year study (2005)(2006)(2007)(2008). Two cropping systems, durum wheat in continuous cropping, and in two-year rotation with leguminous crops, were investigated at Foggia (Southern Italy) in rain-fed conditions. Within each cropping system, two levels of crop management were compared: i) conventional, characterized by a higher soil tillage management and mineral fertilizers application; ii) conservative, with a lower soil tillage management and organic-mineral fertilizers. The seasonal weather greatly affected the wheat yield and quality, inducing lower production in years that were characterized by unfavorable climatic conditions. This trend was found when the conventional treatment was applied, both in continuous cropping and rotations. The effects of cropping systems and crop management pointed out the positive role played by the leguminous crops (common vetch and chickpea) in crop rotation. This introduction improved wheat yield in rotation (6.47% compared to the continuous cropping), improved grain protein content (5.88%), and reduced the productive gap between conventional and conservative treatments (9.24 and 14.14% of the wheat in rotation and continuous cropping, respectively). Conversely, the effects of cropping systems and crop management on soil fertility were not very high, since the differences found at the end of the study in total nitrogen values were poor. However, total organic carbon (16.04 and 17.58% for cropping system and crop management, respectively) and available phosphorus values (11.30 and 7.43%) depend on root organic matter contribution, plant biomass residues, and fertilizations. The suitable crop rotation and the sustainable crop management appear important agronomical practices to improve yield and quality of wheat, and may reduce the environmental risks resulting from conventional intensive cropping systems.

Abstract. More diverse crop rotations have been promoted for their potential to remediate the range of ecosystem services compromised by biologically simplified grain-based agroecosystems, including increasing soil organic carbon (SOC). We hypothesized that functional diversity offers a more predictive means of characterizing the impact of crop rotations on SOC concentrations than species diversity per se. Furthermore, we hypothesized that functional diversity can either increase or decrease SOC depending on its associated carbon (C) input to soil. We compiled a database of 27 cropping system sites and 169 cropping systems, recorded the species and functional diversity of crop rotations, SOC concentrations (g C kg/soil), nitrogen (N) fertilizer applications (kg NÁha ). We categorized crop rotations into three broad categories: grain-only rotations, grain rotations with cover crops, and grain rotations with perennial crops. We divided the grain-only rotations into two sub-categories: cereal-only rotations and those that included both cereals and a legume grain. We compared changes in SOC and C input using mean effect sizes and 95% bootstrapped confidence intervals. Cover cropped and perennial cropped rotations, relative to grain-only rotations, increased C input by 42% and 23% and SOC concentrations by 6.3% and 12.5%, respectively. Within grain-only rotations, cereal + legume grain rotations decreased total C input (À16%), root C input (À12%), and SOC (À5.3%) relative to cereal-only rotations. We found no effect of species diversity on SOC within grain-only rotations. N fertilizer rates mediated the effect of functional diversity on SOC within grain-only crop rotations: at low N fertilizer rates (≤75 kg NÁha ), the decrease in SOC with cereal + legume grain rotations was less than at high N fertilizer rates. Our results show that increasing the functional diversity of crop rotations is more likely to increase SOC concentrations if it is accompanied by an increase in C input. Functionally diverse perennial and cover cropped rotations increased both C input and SOC concentrations, potentially by exploiting niches in time that would otherwise be unproductive, that is, increasing the "perenniality" of crop rotations.
