“…Agricultural hydrogel was reported in 1980s for improvement in efficient use of water and modification of physical properties of soil. The Indian agriculture research institute (IARA) fabricated a new hydrogel (branded as Pusa hydrogel) and explored for agronomic use to overcome drought and to ensure efficient water use in some semi‐arid and arid regions of India 5 . Initially, sodium and potassium polyacrylate were explored for development of agriculture hydrogel due to their superabsorbent and water insoluble nature 6 .…”

Modern world is searching for water efficient agriculture techniques as irrigation is becoming scarce. Limited water resources and more food demand are the two key challenges in agriculture. Hydrogels which can respond intelligently by pH, temperature, light, ionic strength, osmotic pressure, magnetic or electric field changes are termed as intelligent or smart hydrogels which are analogous to conventional hydrogels in preparatory methods and features. Lag phase, constant release and decay phase are three steps involved in release of nutrients from polymeric hydrogels. In fact, hydrogels act as little reservoirs of water and dissolve nutrients that are released in controlled manner anchored by plant roots via capillary action. Hydrogels also sustain optimum amount of water in water stress conditions and reabsorb water in moist conditions which ultimately increases seedling, seed germination, plant growth and crop yield. Fertilizer and salt release are majorly dependent upon pH and temperature followed by diffusion‐controlled mechanism. Cross‐linkers, binders and fillers play pivotal role in determining properties, architecture and hydrogel pores. In comparison to potassium (K+) and phosphate (PO4−3) ions, nitrates (NO3−1) and ammonium (NH4+1) ions exhibited faster release rate. This review spotlights application prospects of three dimensional hydrogel in agriculture. Initially, properties of hydrogels, their classification, preparatory methods, effect of natural‐synthetic‐polymer blending and role of fillers are stated. Afterward, hydrogel functioning, significance, advantages, mechanism of fertilizer release and agriculture specific applications of hydrogels are comprehensively described. In conclusion, extraordinary biocompatible, cheaper, stable, biodegradable, durable, non‐toxic and re‐wettable characteristics of hydrogel systems motivated their utilization in agronomical applications.

“…Owing to their versatility, availability, bio-compatibility, and ability to experience large elastic deformations, gels are the material of choice in many applications such as tissue engineering, [1][2][3] drug delivery, [4][5][6] agriculture, [7][8][9] soft robotics, [10][11][12] autonomous snapping architectures, [13] self folding structures, [14,15] and microfluidics. [16][17][18] Typically, the incorporation of gels in the above applications and devices results in mechanical, chemo-mechanical, or biomechanical constraints that may hinder swelling.…”

Stimuli‐responsive hydrogels that swell under constraints such as spatial geometric confinement are employed in many applications, including biomedical devices and actuators, to perform mechanical work. Due to the heterogeneous deformations that arise from these constraints, the computation of the swelling‐induced stress poses numerical difficulties. This work proposes a simple experimental method based on 3D‐printing technologies to characterize this stress. The swelling is investigated under two types of geometric confinements—transversely constraining and elastically constraining boxes. In the former, the box enforces uniaxial swelling of the gel. The results show that the longitudinal deformations decrease as the transverse stretches increase. The elastically constraining box comprises soft walls with various stiffnesses and sizes that deform in response to the swelling‐induced stress exerted by the gel. By employing elastic plate theory, a method to determine this stress is developed. The results reveal that: 1) the maximum volumetric deformation is achieved by free swelling and 2) the stress gels exert depends on the wall stiffness and non‐linearly decreases as the gel nears its freely swollen state. The insights from this work can be used to optimize the performance of swelling‐based systems and characterize the stress generated due to other stimuli such as pH and temperature.
