“…During the last two decades, other studies followed by applying plastic films instead. Elawady et al (2003) reported 18% yield increase in spinach (Spinacia oleracea L.) [21] whilst Awady et al (2008) found a 141% to 190% increase in tomato fruit yield (Solanum lycopersicum L.) [22] Other studies performed in Iraq highlighted positive effects of plastic SWRSs on both yield and water use efficiency in the chili pepper (Capsicum annuum L.) [23,24]. Kavdir et al (2014) investigated the use of impermeable membranes in irrigated sandy soils and an increase in corn production was assessed to be as high as 238% more than under normal conditions [25].…”

The potential to use Subsurface Water Retention Systems (SWRSs) to combat desertification and improve agriculture in arid and semiarid areas has already been investigated and proved promising. Nevertheless, a lack of specific machinery has prevented this technology from demonstrating its effectiveness on vast areas. In the present study, a specific prototype is presented along with the results obtained from a preliminary study conducted to assess effectiveness, performance and associated cost. During the test, the machinery permitted the construction of a SWRS 100 cm belowground using a 140 kW tractor. The effective field capacity (EFC) averaged at 0.19 ha h–1 whilst total cost was estimated to be as high as 4800.00 € ha–1. However, 93% of the cost was associated with the purchase cost of the removable impermeable film. A removal operation was also investigated using a 42 kw excavator for evaluating the EFC and cost which averaged at 0.2 ha h–1 and 655.79 € ha–1, respectively.

“…As for the effect of the interaction between poultry manure and the elements, the results showed that there were significant differences between the treatments if the highest value was for the M 2 E mg treatment (1.5400) and the lowest value for the M 0 E zn treatment (1.0111), This is attributed to the overlapping effect between the poultry manure and the elements and the role of organic matter in retaining the nutrients. Through its effective aggregates that act as a chelating substance that preserves the elements from loss and increases their readiness [20,29]. As for the effect of the triple interference between the treatments, if the highest value is for the treatment P 2 M 2 E mg (1.6300) and the lowest value is for the treatment P 0 M 0 E mg (0.3033), this is due to the overlapping effect of the three-way factors involved in the experiment.…”

This study was conducted to determine the effect of Bentonite mineral, poultry manure, and the addition of some elements on the chemical properties of the soil. The experiment was carried out in a split-plate design using completely randomized blocks (RCBD). The experiment included 81 experimental units resulting from the intersection of three levels of bentonite mineral (P0, P1, P2) and three levels from poultry manure (M0, M1, and M2) and three chemical elements: Magnesium, Zinc, and Copper (Emg, Ezn, and Ecu) separately and the effect of these factors on the chemical properties, the results showed that the P2 addition level to Bentonite mineral outperformed the rest of the levels in affecting the chemical properties, namely EC, PH, CEC, and OM. The M2 addition level to poultry waste outperformed the rest of the levels in the chemical properties studied, EC, PH, CEC, and OM. The binary interactions between the metal and poultry manure showed a significant effect, and the P2M2 treatment outperformed the rest of the treatments. As for the interaction between the metal and the chemical elements, the P2Ezn treatment gave the best effect on the EC and CEC properties, while the P2Emg treatment gave the best effect on the PH and OM properties, and the interaction between Poultry manure and elements: the M2Ezn treatment gave the best effect on the EC and CEC properties, while the M2Emg treatment gave the best effect on the PH and OM properties.
