“…In this rain-fed region, although rainfall is relatively sparse throughout the year, most is concentrated during maize growth period. Uneven high intensity precipitation in short periods occurs frequently, and contributes to the accumulation and leaching of soil NO 3 − -N. 34 In our 3-year trial, total rainfall during the growth period was 480 mm in 2018, which was significantly higher than the 390 and 372 mm observed in 2016 and 2017, respectively. The NO 3 − -N retention capacity of soil is small as NO 3 − -N has a negative charge.…”

BACKGROUND: A one-off application of combining controlled-release urea (CRU) and conventional urea has been recommended for the reduction of nitrogen (N) loss and improvement of grain yield. However, the effects of combining CRU and urea with different surface mulching has not been studied in detail, and the underlying agronomical and physiological mechanisms need to be more clearly understood.RESULT: A 3-year field study was conducted to determine the effects of combining CRU and urea with different surface mulching on dry matter, N accumulation and translocation, nitrate nitrogen (NO 3 − -N) residuals and loss in maize grown under rain-fed conditions. Three surface mulching [plastic film mulching (FM), straw mulching (SM) and no mulching (NM)] as well as three N fertilization [combining CRU and urea with 1:2 as the baseline application (NC), a split urea application with 4:3:3 (NU) and a N control (N0)] were used. The FM under NC fertilization increased N uptake, decreased NO 3 − -N residual in the deep soil layer, and decreased N loss. The FM, SM and NM under NC fertilization increased 3-year mean grain yields by 5.8%, 4.0% and 4.6%, respectively, compared to that under NU fertilization. The FM under NC fertilization showed the highest grain yield and economic return. CONCLUSION: Properly managing N application by mixing CRU and urea in a one-off application combined with plastic film mulching may have the potential to provide a better compromise among grain yield, N loss and economic returns for maize in rain-fed farmland.

“…Unfortunately, this excessive N application has led to decreased NUE, elevated soil N buildup, heightened nitrate leaching, and intensi ed greenhouse gas emissions, thereby exacerbating environmental pollution (Jiang et al 2016(Jiang et al ,2018Liu et al 2017). The use of PFM is known to in uence soil properties and microbial activities (Jiang et al 2016(Jiang et al ,2018Zhou et al 2012), both of which have impacts on soil N transformations, thereby affecting soil N supply and retention (Guo et al 2019;Liu et al 2015).…”

Aims Plastic film mulching induces significant shifts in soil temperature and water balance, thereby influencing microbial activities, particularly those associated with nitrogen (N) transformations. However, its effects on interactions between N fate and soil N transformations remain unclear. Methods We investigated the complex interplay of soil N transformation processes using a 15N tracing method, N availability, and N fate under plastic film mulched ridges (PFM), in contrast to a non-mulched flat system (control). Results PFM resulted in 20–28% reduction in gross N mineralization and nitrification rates and increased rates of gross microbial N immobilization. Maize showed a 19% increase in N uptake and a 127% increase in N accumulation in the PFM-treated soil (up to 80 cm depth) compared to the control. PFM effectively inhibited N leaching, while also reducing N2O and NH3 gas emissions (by 32 kg N ha-1). In the early stages of maize growth, PFM-treated soil showed increased N availability due to accelerated rates of gross N mineralization and nitrification, which in turn bolstered N uptake by both maize and microorganisms. Furthermore, PFM effectively mitigated gaseous N emissions and N leaching, contributing to increased soil N retention and N use efficiency. As the rates of gross N mineralization and nitrification declined in the later stages of maize growth, PFM maintained substantial N availability. This was achieved by limiting NO3- leaching and microbial N immobilization, resulting in heightened N uptake and increased maize yield. Conclusion Plastic film mulching produced changes in soil N transformation processes that included gross N mineralization, nitrification, and immobilization rates. These changes manifested in increased N availability, maize N uptake, soil N retention, and reduced N losses.

“…The practice of reducing water losses from the soil, keeping it moist, and using the lining of the pits and furrows with plastic film has shown promise in the cultivation of yellow passion fruit Passiflora edulis Sims (Cavalcante et al 2005) and the pepper Capsicum annuum (Lima Neto et al 2013. The main benefits of plastic film in soil for plants are the reduction of nutrient losses-mainly nitrogen and potassium (Guo et al 2019), water losses through lateral flow (Zhao et al 2018;Lima Neto et al 2021), and maintenance of a wetted soil in the root absorption zone, promoting greater absorption of water and nutrients, with productivity gains (Dukare et al 2021;El-Beltagi et al 2022).…”

In semi-arid regions, agricultural production is often limited due to scarcity and rainfall irregularities, and, therefore, the production system depends on irrigation. In this direction, the research aimed to evaluate the influence of the reduction of water losses in the soil through the coating of the lateral faces of the planting furrows with plastic film, by lateral infiltration of water and bovine biofertilizers for growth in height, production, and chlorophyll responses of tomato cv. Fascínio F1 irrigated with moderately saline water. The experiment was carried out in randomized blocks, in a 2 × 3 factorial scheme, with 4 replicates and 21 plants per plot. Different conditions were used and compared with each other: the furrow had side coating or not, and the soil received a common biofertilizer (fresh lactating bovine manure), chemically enriched fertilizer (common biofertilizer, milk, molasses, and gypsum), or no fertilizer at all. The variables evaluated were soil moisture, plant height, a, b, and total chlorophyll content, number and average fruit mass, tomato production, and productivity. The enriched bovine biofertilizer associated with the lateral furrow coating increased the synthesis of chlorophyll pigments, the number of fruits per plant, and the productivity of tomato cv. Fascínio F1. Protecting the faces of the furrows against water losses from the root environment of plants keeps the soil moist, stimulates the synthesis of chlorophyll, and increases the average mass of the fruits. The common bovine biofertilizer promotes greater growth in plant height, and the chemically enriched biofertilizer increases the average weight of tomato fruits.
