“…The difference between applied 0.1% and 0.2% concentration of PVA were insignificant, but, it had significant effect with applied 0.0 % and 0.05 % on faba bean seed kg fed -1 ., in second season. These results are in agreement with those obtained by Kukal et al (2007), Chandrika et al (2014), Jiang et al (2016) and Yin et al (2016).…”

“…Hence, the average increased in ETa compared to zero concentration PVA treatment reached 527.18 and 502.39 mm in first and second season, respectively. These results were in agreement with those obtained by Jiang et al (2016), Yin et al (2016) and Abobatta (2018) who observed that the density of chain cross linking creates an expressive amount of free volume between the polymer network. This in turn, combined to the presence of huge number of hydrophilic groups, has the ability of water absorption and retention for large amounts of water, on the order of 10 to 1000 g/g (1.000-100.000%).…”

Quantifying local crop response to irrigation is important for establishing proper irrigation management approaches.To apply that, a field experiment was carried out to evaluate the effect of three available soil moisture depletion(ASMD) levels, 25 %, 50 %, and 75% applied using solid set sprinkler irrigation system in combination with four concentrations (0.00%, 0.05%, 0.1% and 0.2 %)of poly vinyl alcohol soil conditioner. The combined effect of water regimes and different concentrations of soil conditioner was studied on faba bean (Vicia faba cv Giza 843), The experiment was carried out in the semiarid climate of northeast Farm of El-Ismailia Agricultural Research Station, El-Ismailia Governorate Egypt during two successive seasons (2012/2013 and 2013/2014).Evapotranspiration (ETa), yield productivity of faba bean, water use efficiency and macronutrients uptake were also evaluated. Results showed that the actual seasonal crop evapotranspiration (ETa) for ASMD treatments varied between (1605.36 -2482.45m 3 fed -1 .) in the first season (2012/2013) and (1439.26 -2457.01m 3 fed -1 .) in the second season (2013/2014). There are three options to calculate seasonal ETc for faba bean crop in Ismailia condition. So, it can be use FAO-24RD, PMd or Droogers and Allen ( 2002)methods. Moreover,obtained data reveal that application of polyvinyl alcohol(PVA)synthetic soil conditioners (with high concentration), decreased available soil moisture depletion (ASMD) in sandy soil and caused a significant increase in faba bean yield, water use efficiency (WUE) and improved the macronutrient uptake by faba bean yield. Finally, the results clearly showed that the significant effect of PVA at (0.1or 0.2 %) concentration was most observed at 50% ASMD.

“…Furthermore, manual management and improvement measures were also important for coordinating the ES relationships. These measures include building bench terraces to change the topographical conditions and implementing artificial rainwater collection measures to fully utilize water resources (Wei et al, 2016), improving soil properties to increase organic matter and silt content (with greater emphasis on organic fertilizer) (Ankenbauer and Loheide, 2017;Geng et al, 2017), covering the soil surface (e.g., straw mulching) to decrease water evaporation and control soil erosion (Fernández and Vega, 2016), applying chemical measures such as water-retaining agents (Yin et al, 2016) and transpiration-controlling preparation (Li et al, 2015) to decrease water consumption, and finally, employing environmentally friendly tillage methods, such as reduced/ no-tillage, straw retention, crop rotation, forest-crop intercropping, and mix-sowing of shrubs and grass (Fang et al, 2016).…”

Soil erosion control (SEC), carbon sequestration (CAS), and soil moisture (SMO) strongly interact in the semi-arid Loess Plateau. Since SMO has supportive effects on SEC and CAS, it can be considered as ecosystem service (ES), and there is an immediate need to coordinate the relationships among these ecosystem services (ESs) to promote the sustainability of vegetation recovery. In this study, we quantified the ESs, ES trade-offs, and the environmental factors in 151 sample plots in the Ansai watershed, and we used a redundancy analysis (RDA) to clarify the effects of environmental factors on these ESs and their trade-offs. The results were as follows: (1) the general trend in the SEC of vegetation types was Robinia pseudoacacia (CH)>native grass (NG)>small arbor (ST)>Hippophae rhamnoides (SJ)>artificial grass (AG)>Caragana korshinskii (NT)>apple orchard (GY)>crop (CP); the CAS trend was CH>SJ>NT>AG>CP>ST>GY>NG; and the SMO trend was CP>NG>GY>AG>SJ>ST>CH>NT. (2) For SEC-SMO trade-offs, the influence of vegetation type, altitude, silt and sand composition was dominant. The arrangement of NG, AG, and SJ could decrease the extent of the trade-offs. (3) For CAS-SMO trade-offs, vegetation coverage and types were the dominant factors, but the effects were not complex. The extent of these trade-offs was lowest for NT, and that for SJ was the second lowest. (4) Considering the relationships among the three ESs, SJ was the most appropriate afforestation plant. Combing the vegetation types, slope position, slope gradient, and soil properties could regulate these ES relationships. The dominant factors influencing ES trade-offs varied among the different soil layers, so we must consider the corresponding influencing factors to regulate ESs. Moreover, manual management measures were also important for coordinating the ES relationships. Our research provides a better understanding of the mechanisms influencing the relationships among ESs.

Water unavailability and shortage are severe problems in agriculture, particularly in loamy sandy to sandy soil, since they inhibit plant growth, resulting in a low crop yield. Using biocompatible hydrogels with good water absorption and retention properties is essential to improve plant growth under unfavorable situations. This work aimed to investigate the influence of the carboxymethyl cellulose/nano-calcium carbonate (CMC/NCC) composite amended in the loamy sand soil on maize growth in a pot experiment. Two types of CMC hydrogels with 1 or 5% wv–1 of NCC, designated as CMC/NCC1 and CMC/NCC5 composite hydrogels, respectively, were selected in this study. Incorporating NCC nanoparticles into the physically crosslinked CMC hydrogel networks exhibited the ability to increase water absorption of the pristine and nanocomposite CMC hydrogels. We investigated the properties of hydrogels of different compositions and dosages added to cause increased water absorption capacity (WAC), water holding capacity (WHC), and carbon dioxide (CO2) evolution. The CMC/NCC hydrogels had better swelling capacity than those of the pristine CMC hydrogels at all pHs. The amendment of hydrogels in loamy sand soil enhanced the soil WHC. The CO2 evolution gradually increased with incubation time in the order of CMC > CMC/NCC1 > CMC/NCC5 > the control soil. The chlorophyll contents, the biomasses of the above- and below-ground parts, and root length were observed as the determining parameters of maize growth. Although the total chlorophyll contents of maize leaves did not significantly change with hydrogel supplementations, the root biomass and cumulative root length of the maize grown in the soil amended with hydrogels were significantly lower than that of untreated soil without changing the above-ground biomass. This suggests that the maize plant growing in the loamy sand soil amended with CMC/NCC hydrogels could affect the allocation of carbon without changing the overall crop yield. Thus, the CMC/NCC hydrogels can be used as an alternative soil amendment for agricultural applications in the loamy sand soil to maintain plant growth.
