“…During weeks of rainfall greater than or equal to 50 mm, ambient air temperatures were lower or equal to soil temperatures in all treatments. This increased water content within the treatments may have raised the specific heat of the soil [49]. As average ambient temperatures decreased below 26 • C during the fall, soil temperatures under all treatments were greater than air temperature, which is consistent with observations from a study by Yang et al [50].…”

Sustainable landscapes provide environmental, social, and financial benefits, with interest and adoption increasing due to environmental awareness. Ornamental ground-cover systems have garnered interest in the landscape due to the reduced need for water, fertilizers, pesticides, and maintenance compared to typical landscapes; however, limited research on groundcover ability to modulate soil conditions or suppress weeds exists. This study explored how ornamental groundcover systems impact the sustainability of landscapes. The effects of ground-cover growth habit (matting; bunching) and irrigation delivery method (micro spray; overhead) on soil temperature, volumetric water content (VWC), and electric conductivity (EC), along with impacts on weed growth, soil microbial communities, and plant coverage, were measured. Soil temperatures were generally lower under groundcover species with a matting growth habit, and to a lesser extent, bunching growth habits, in comparison to the warmer fallow systems. Groundcovers with a matting form led to lower VWC values compared to taxa with other growth habits, particularly when micro-irrigated. Plant form did not significantly influence EC values; however, micro spray irrigated plots had significantly higher EC values, likely attributed to irrigation spray patterns. Micro spray irrigation in tandem with matting growth habit taxa decreased weed density more effectively than taxa with bunching growth habits or groundcovers maintained under overhead irrigation. Selection of groundcover species with greater foliar coverage along with implementing more efficient irrigation practices can decrease soil temperatures, soil moisture, and weed density. Incorporating groundcovers in the landscape can decrease maintenance requirements and water/chemical use, thus increasing sustainability and decreasing environmental consequences.

The mechanism of greenhouse tomato growth and yield under the integrated water and fertilizer of moistube irrigation (MI) is not clear. Thus, to fill the research gap, a completely randomized trial design was used to study the effects of different irrigation amounts (I; to realize different I, the tube working pressure was 1 (I1), 2 (I2), 3 (I3) m) and fertilizer amounts (F, N-P-K: 20%-20%-20%; the F at a single time was 100 (F1), 200 (F2) and 300 (F3) kg/ha) on growth and yield of tomato. The results showed that with an increase in I, the photosynthetic rate (Pn) of leaves and total dry matter mass (TDM) first increased and then decreased, while the nutrition and the flavor indexes of fruit decreased. With an increase in F, the Pn of leaves, the TDM of tomato and the fruit quality increased at first and then decreased. The effects of I on the yield of tomato was higher than that of F. With an increase in I, the partial fertilizer productivity (PFP) increased at first and then decreased, and the water use efficiency (WUE) decreased by 13.96%. With an increase in F, the WUE increased at first and then decreased, and the PFP decreased by 148.97%. The conclusion based on a spatial analysis was consistent with the comprehensive evaluation of yield and water use efficiency, which showed that I2F2 was the best.

“…The impacts in soil, water and on organisms are still unknown. Recent studies address research questions concerning the environmental impacts on crop-soil systems, in laboratory and on-field trials for a range of different crops, e.g., wheat, maise, rice, oat, soybean, cotton, cabbage, lettuce and carrots, tomatoes, watermelon [20,21,65,[70][71][72]. Studies identify plastic's general impact on physicochemical properties [73][74][75][76].…”

“…In agriculture, the application of plastic mulch film benefits from the favourable material characteristics of plastic. It creates positive effects: mainly for production but also for the environment (e.g., increasing crop yields, increasing and maintaining soil moisture and temperature, reducing soil-based evapotranspiration and soil salinity, and increasing bacterial diversity [20][21][22]. Environmentalists criticise the application of plastic mulch films.…”

Plastic Emissions from Mulch Film and Abatement Measures — a Model-Based Assessment for Germany

Plastic mulch film in agriculture fulfils multiple purposes. In Germany, farmers apply mulch films to produce crops with specific climate soil conditions. While plastic mulch film benefits agricultural production, the emission of plastic debris and microplastic raises environmental concerns. To date, alternative technologies cannot adequately replace plastic mulch film emitting less plastic. Thus, abatement measures are required to reduce plastic emissions and maintain the application. In a model-based analysis for Germany, we find at the sector-level annual plastic emissions of 202 tons, and we identify regional emission hotspots with more than 500 grams per hectare utilised agricultural area in regions with intensive plasticulture production. Increasing the film thickness to 40 to 50 micrometres reduces plastic emissions by 20 to 40 per cent, creating abatement costs from 120 to 130 Euros per kilogram of abated plastic. Increasing prices for plasticulture products by 1 to 10 per cent can compensate for the increased material costs of thicker mulch films. Thus, increasing the film thickness can be an effective and efficient abatement measure, depending on farmers' willingness to apply thicker mulch films and consumers' willingness to pay increased prices. Our findings contribute to the interdisciplinary puzzle of plastic emissions from mulch films. They can be valuable information for agricultural and environmental discussion but require updating and complementation in future research.
