“…One of the main disadvantages of the SDI is the possibility of emitters clogging due to root intrusion, due to the moisture near the drippers. Chemigation with TFN is able to avoid this problem, since at each application, an amount of the herbicide is accumulated near the emitter's outlet, forming an acidic environment which can inhibits root growth and, consequently, its intrusion into the emitters orifice (Cai et al, 2019;Lima et al, 2014). This technique has been widely recommended as a preventive in field measure, especially in crops extremely sensitive to water stress, such as sugarcane cultivars (Dalri et al, 2021;Lima et al, 2014;Simões et al, 2018).…”

“…In addition, this system use can be an efficient solution for irrigation in corners where the center pivot cannot reach, what can increase 15 to 20% of the available area in a square parcel (Sorensen et al, 2021;Tilley et al, 2016). However, in SDI the emitters are buried in the ground and can become clogged by root intrusion, reducing the system efficiency and its useful life (Cai, et al 2019;Lima et al, 2014).…”

Modeling and simulation of trifluralin herbicide movement due to its application on soils by chemigation

et al. 2022

The Trifluralin (TFN) is a pre-emergent herbicide which is widely used in agriculture. Usually, this pesticide is directly applied to the soil, where it can remain for long periods or can be transported. In this sense, knowing the dynamics of an herbicide soil transport is essential to avoid environmental contamination problems and risks to human health. Thus, this study aims to model and simulate TFN movement on soils with two different textures, a sandy loam and clay loam soil. It was considered that the herbicide was applied via chemigation trough a subsurface drip irrigation system, under a non-steady regime. Therefore, the transport parameters of TFN in these soils and physical-hydric characteristics of these were used, while the physical environment modeling were conducted using the Hydrus 2D software. The results showed that both in sandy and clayey soils, the TFN tends to be retained by the soil, close to where it was applied, not exceeding a layer greater than 2.5 mm outside the dripper radius, even in more favorable conditions such as the presence of irrigation. Finally, it could be concluded that this herbicide movement in the soil is of low potential, due to this product high solid-liquid partition coefficient (Kd), even in sandy soil, which has low cation exchange capacity (CEC).

The sustainable development goals (SDGs), including 17 goals and 169 targets, were adopted unanimously by the United Nations General Assembly in 2015.The aims are to end poverty, protect the planet, and ensure peace, health, and prosperity of all people over the world. Toward the SDGs, human beings must effectively utilize the global resources, such as (1) oceans, seas, rivers, lakes, and so forth that supply us with water and aquatic resources; (2) land, ground, and soil where we can raise agricultural crops and livestock; (3) forests and woods that provide us with lumber and paper and convert carbon dioxide to oxygen; and (4) fossil fuel and mineral resources, which are essential to our modern lives. The use of macroporous ceramics is definitely conducive to the solutions to achieve the SDGs, because it can help solve many of the related technical issues. This review addresses macroporous ceramics primarily for filtration and purification, agriculture and fisheries industry, thermal managements, sensing devices, and constructions, which contribute to achieving SDGs.

“…Many scholars have discussed and tested the possibility of low-quality water source irrigation. Irrigation sources including reservoir water sources [17,18], urban wastewater [19], sewage [20,21], recycle water [22,23], saline water [24], and brackish water [15] are mainly low-quality water sources with biochemical reactions and blockage, but there are few studies on physical clogging. The few studies mostly focus on the influence factors on clogging performance [25], sediment particle motion state [26], adaptive selection [27], and optimal design [28] of emitters.…”

Drip irrigation technology has obvious advantages in solving the shortage of agricultural water. The demand for using low-quality water sources for irrigation is becoming urgent. Research on the physical blockage formation has become the main part of solving the emitter blockage in China. The purpose of this study is to investigate the blockage characteristics of the emitters in the drip irrigation system with a low-quality water source and to provide some basis for the anti-clogging measures. Therefore, we configured different concentrations (1.8 g/L, 2.8 g/L, 3.8 g/L) and different particle sizes (0–0.054 mm, 0.054–0.075 mm, 0.075–0.1 mm) of low-quality water sources and carried out drip irrigation tests. The holistic and local characteristics of the physical blockage occurrence and distribution were compared under the sand-laden water source irrigation, then the structure and element composition of the blockage material were analyzed. The results show that the clogging characteristics are related to the emitter types, sediment content, and sediment particle size. The higher sediment concentration means that the single emitter is more likely to be blocked completely, and the whole clogging development is short and quick. However, at lower sediment concentration treatments, the probability of complete clogging decreases, and the clogging process is uniform and slow. The blockage position of large flow channel emitters (E1) appears at the head and middle of the drip irrigation tape, and the internal blockage usually occurs at the inlet. The small size channel emitters (E2 and E3) are concentrated in the head and end of drip irrigation tape, and the internal blockage usually occurs in the low-speed zone of the labyrinth channel such as the inlet fence. The internal blocked material is the accumulation structure formed by sediment particles and the coupled precipitation aggregate formed by the reaction of various chemical ions. Among them, the mixing of large and small sediment particles is more inclined to form a stable blocking skeleton structure.
