“…Clinoptilolites are synthetic substances with high cation exchange properties with the potential to retain ammonium ions (Jakkula and Wani, 2018). Hydrogel, polyvinyl alcohol, and anionic polyacrylamide are soil conditioners reported by Seddik et al (2019) noticed to increase the total nitrogen content of the soil. Although, according to Youssef et al (2019), polyvinyl alcohol had no significant effect on the nitrification process.…”

To meet the global demand for food, several factors have been deployed by agriculturists to supply plants with nitrogen. These factors have been observed to influence the soil nitrification process. Understanding the aftermath effect on the environment and health would provoke efficient management. We review literature on these factors, their aftermath effect on the environment and suggest strategies for better management. Synthetic fertilizers and chemical nitrification inhibitors are the most emphasized factors that influence the nitrification process. The process ceases when pH is <5.0. The range of temperature suitable for the proliferation of ammonia oxidizing archaea is within 30 to 37oC while that of ammonia oxidizing bacteria is within 16 to 23oC. Some of the influencing factors excessively speed up the rate of the nitrification process. This leads to excess production of nitrate, accumulation of nitrite as a result of decoupling between nitritation process and nitratation process. The inhibition mechanism of chemical nitrification inhibitors either causes a reduction in the nitrifying micro-organisms or impedes the amoA gene's function. The effects on the environment are soil acidification, global warming, and eutrophication. Some of the health effects attributed to the influence are methemoglobinemia, neurotoxicity, phytotoxicity and cancer. Biomagnification of the chemicals along the food chain is also a major concern. The use of well-researched and scientifically formulated organic fertilizers consisting of microbial inoculum, well-treated organic manure and good soil conditioner are eco-friendly. They are encouraged to be used to efficiently manage the process. Urban agriculture could promote food production, but environmental sustainability should be ensured.

“…Dahri et al (2019) found that Superabsorbent Polymers (SAP) in powder and crystal forms decreased soil bulk density, increasing porosity and field capacity. Seddik et al (2019) showed synthetic soil conditioners improved soil properties, enhancing field capacity and nutrient availability, positively impacting plant growth and yield in sesame and wheat.…”

This study evaluated the effects of two Super Absorbent Polymers (SAPs) types, P1 and P2, and four microbial isolates (Trichoderma harzianum, two Actinomycetes sp., and Bacillus subtilis) on improving some soil physical properties. The results showed that SAP application, alone or in combination with microbes, significantly reduced bulk density by 6.1% and increased porosity by 5.2% compared to the control. Specifically, the P1C (P1 polymer + Actinomycetes 1) treatment increased water holding capacity by 48.7%, field capacity by 169.4%, permanent wilting point by 180.5%, and available water by 149.8% compared to control based on data from the results. The P1C treatment improved soil properties and moisture characteristics. The synergistic effect of polymers and microbes emerged as an effective strategy to modify soil properties. This study provides valuable insights into using SAP-microbe amendments to enhance soil physical properties, water availability, and agricultural productivity in drought conditions.

“…This group will include amendments like biochar, superabsorbent polymer (SAP), nonwoven geotextiles, water absorbing geocomposite (WAG) or biodegradable water absorbing geocomposite (bioWAG). Their function is to retain additional amounts of water in the soil profile through a reduction of water infiltration or evaporation [1][2][3][4][5][6]. Water conservation is essential due to the high level of water consumption for agricultural purposes and progressing climate change.…”

Soil amendments are substances added to the soil for moisture increment or physicochemical soil process enhancement. This study aimed to assess the water conservation efficiency of available organic soil amendments like bentonite, attapulgite, biochar and inorganics like superabsorbent polymer, and nonwoven geotextile in relation to the newly developed water absorbing geocomposite (WAG) and its biodegradable version (bioWAG). Soil amendments were mixed with loamy sand soil, placed in 7.5 dm3 pots, then watered and dried in controlled laboratory conditions during 22-day long drying cycles (pot experiment). Soil moisture was recorded in three locations, and matric potential was recorded in one location during the drying process. The conducted research has confirmed that the addition of any examined soil amendment in the amount of 0.7% increased soil moisture, compared to control, depending on measurement depth in the soil profile and evaporation stage. The application of WAG as a soil amendment resulted in higher soil moisture in the centre and bottom layers, by 5.4 percent point (p.p.) and 6.4 p.p. on day 4 and by 4.5 p.p. and 8.8 p.p. on day 7, respectively, relative to the control samples. Additionally, an experiment in a pressure plate extractor was conducted to ensure the reliability of the obtained results. Soil density and porosity were also recorded. Samples containing WAG had water holding capacity at a value of −10 kPa higher than samples with biochar, attapulgite, bentonite, bioWAG and control by 3.6, 2.1, 5.7, 1 and 4.5 percentage points, respectively. Only samples containing superabsorbent polymers and samples with nonwoven geotextiles had water holding capacity at a value of −10 kPa higher than WAG, by 14.3 and 0.1 percentage points, respectively. Significant changes were noted in samples amended with superabsorbent polymers resulting in a 90% soil sample porosity and bulk density decrease from 1.70 g∙cm−3 to 1.14 g∙cm−3. It was thus concluded that the water absorbing geocomposite is an advanced and most efficient solution for water retention in soil.
