“…Alternatively, mass discharge can be estimated more directly by physically sampling soil porewater above the capillary fringe (or as deep as practicable) using lysimeters because PFAS concentrations in soil porewater with depth represent the PFAS fraction subject to migration to groundwater. Multiple soil lysimeters within vadose zone sources sampled at multiple time points have yielded rigorous estimates of contaminant mass discharge without modeling uncertainty (e.g., Del Campo et al, 2019).…”

A Society of Environmental Toxicology and Chemistry (SETAC) Focused Topic Meeting (FTM) on the environmental management of per-and polyfluoroalkyl substances (PFAS) convened during August 2019 in Durham, North Carolina (US).Experts from around the globe were brought together to critically evaluate new and emerging information on PFAS including chemistry, fate, transport, exposure, and toxicity. After plenary presentations, breakout groups were established and tasked to identify and adjudicate via panel discussions overarching conclusions and relevant data gaps. This manuscript is one in a series and summarizes outcomes of presentations and breakout discussions related to 1) primary sources and pathways in the environment; 2) sorption and transport in porous media; 3) precursor transformation; 4) practical approaches to the assessment of source zones; 5) standard and novel analytical methods with implications to environmental forensics and site management; and 6) classification and grouping from multiple perspectives. Outcomes illustrate that PFAS classification will continue to be a challenge and additional pressing needs include increased availability of analytical standards and methods for assessment of PFAS and fate and transport, including precursor transformation. While the state of the science is sufficient to support a degree of site-specific and flexible risk management, effective source prioritization tools, predictive fate and transport models, and improved and standardized analytical methods are needed to guide broader policies and best management practices.

“…It should be noted that the agronomic conditions in 2010 and 2011 were like the standard conditions of the FAO, but those in 2009 were very far from the standard, reducing the transpiration of the turf. This may be due to agronomic practices in 2009, the year in which the planting and establishment of the lawn took place (Martin del Campo et al ., 2019).…”

“…The addition of OM and hydrogel amendments is a common practice since they increase efficiency in water and agrochemicals use (Aamlid et al, 2009; Ullah et al, 2015; Martin del Campo et al, 2019). Hydrogels are hydrophilic polymers that absorb water, improve soil porosity, aeration, infiltration, nutrient transport and release, and water absorption that promote plant growth (Akhter et al, 2004; Abedi‐Koupai et al, 2008; Ullah et al, 2015).…”

Irrigation and Drainage

The irrigation schedule in arid areas has to be efficient in order to reduce losses due to evaporation and deep infiltration. Irrigation optimization poses the need to establish with precision the value of actual evapotranspiration (ETa), and the crop coefficient (Kc). The water soil availability can be increased using hydrogel and organic matter amendments, and their effects could vary ETa and Kc. The aim of this study was to determine the ETa, and Kc of an experimental site with lysimeters on the Spanish Mediterranean coast cropped with a turf grass variety, Agrostis stolonifera ‐L‐93, under field conditions, and amended with hydrogel and organic matter. Reference evapotranspiration (ET0) was determined from meteorological data (FAO‐Penman‐Monteith equation). ETa was calculated from the water balance, and Kc was obtained by dividing ETa by ET0. Kc was calculated and compared on a yearly, monthly and daily basis. In summer, the differences between amendments become manifest:Unamended lysimeter (100% sand) had Kc values (0.92‐1.16), similar to organic matter amended lysimeter (0.99‐1.17). Maximum and minimum Kc values for the hydrogel amended lysimeters (1.04‐1.52) were higher than those from the other because of the ability of this compound to retain water, which facilitated evapotranspiration. Finally, hydrogel helped to maintain the turf grass quality.

“…On soil bund and exclosure plots, the loss of soluble N via leaching was reduced (Table 8, 9). Notably, the percentage of leached N tends to be less when drainage volume is less (Martin et al., 2019), which also is associated with improved soil physical qualities, increased soil organic matter, and less leaching (Carmo et al., 2017). However, a link was discovered between rising fertilizer application rates and increasing percentages of N leaching (Martin et al., 2019), as well as gaseous losses (Elias, 2002).…”

Agricultural sustainability and land degradation can be monitored through studying soil nutrient dynamics. This study was conducted to investigate the balance and stocks of nitrogen (N) and phosphorus (P) under major land use types and land management (LM) practices in three contrasting agroecological environments in Ethiopia. We employed a nutrient monitoring approach and assessed soil N and P inputs and outputs at watershed and plot scales. Field data were collected from 72 sites representative of the major land uses of the three watersheds for the watershed scale analysis. In addition to the watershed data, 16 experimental runoff plots were established and the response of nutrient balances to improved LM practices for the major land uses, including cropland with three treatments (control, farmyard manure [FYM] and soil bund), grazing land with three treatments (control, exclosure and FYM + exclosure) and bushland with two treatments (control and exclosure). Nutrient balances, flows and stocks varied significantly among agroecological settings, land‐use types and LM practices. Severe and negative N balances were found in all agroecological environments, with midland (−70.8) > highland (−61.7) > lowland (−50.3 kg ha−1 yr−1), whereas slightly positive P balances were found in all agro‐ecosystems. As a result, the midland (4.2% yr−1) and highland (2.1% yr−1) sites had greater N depletion rates than the lowland site (1.0% yr−1). Our results also demonstrated that applied LM practices improved N balances: by 32%–40% in cropland through FYM and mineral fertilizer, by 7%–18% in grazing land via FYM and exclosure, and by 6%–36% in degraded bushland via exclosure, implying that, implementing FYM and mineral fertilizer for cropland and implementing FYM with exclosure on non‐croplands can reverse nutrient depletion in the study sites and in other areas having similar agroecological conditions.
