“…Maximising the duration of enzymatic activity is one of the main focuses of research: this can be achieved by their immobilisation on ceramic supports, porous resins and nanoparticles (Zdarta et al, 2018), by creating cross‐linked enzyme aggregates with agents such as chitosan (Xu et al, 2018), or by synthetic humic‐enzymatic complexes (Burns et al, 2013). Recent studies aimed at prolonging the activity of natural and inoculated soil enzymes pointed out the effectiveness of altering the plant populations to optimise pH and soil aeration (Bueis et al, 2018) or soil tillage techniques to optimise water availability (Jat et al, 2021).…”

Soil enzymes are crucial in mediating ecosystems' responses to environmental drivers, so that the comprehension of their sensitivity to drivers of global change can help make predictions of future scenarios and design tailored interventions of biomanipulation. Drivers of global change usually act in combination of two or more, and indirect effects of one driver acting through modification of another one often occur, yet most of both manipulative and meta‐analysis studies available tend to focus on the direct effect of one single driver on the activity of specific soil enzymes. One of the biggest challenges is, therefore, represented by the difficulty in assessing the interactions between different drivers, due to the complexity of disentangling the single direct effects from the indirect and combined ones. In this review, after elucidating the general mechanisms of soil enzyme production and activity regulation, we display the state‐of‐the‐art knowledge on direct, indirect and combined effects of the main drivers of global change on soil enzyme activities, identify gaps in knowledge and challenges from research, plus we analyse how this can reverberate in the future of biomanipulation techniques for the improvement of ecosystem services. We conclude that qualitative but not quantitative outcomes can be predicted for some interactions such as warming + drought or warming + CO2, while for other ones, the results are controversial: future basic research will have to center on this holistic approach. A general trend toward the overall increase of soil enzyme activities and acceleration of biogeochemical cycles will persist, until an inflection will be caused by factors such as future shifts in microbial communities and changes in carbon use efficiency. Applied research will develop toward the refinement of “in situ” analytical systems for the study of soil enzyme activities and the support of bioengineering for the better tailoring of interventions of biomanipulation.

“…Soil enzymes are key indicator of soil quality in crop production systems and direct biochemical processes for nutrient cycling C, N and P; organic and inorganic fertilizers significantly impact soil quality [22]. In this study, integrated use of RHB and EFBB with fertilizer (T1 and T2) increased the dehydrogenase (DHA) enzyme activities up to 50.9 and 64.8%, respectively, over the recommended fertilizer dose (RFD: T3) under AWD irrigation, and in the CF it was 41.1 and 51.2%.…”

“…Biochar application to soil may enhance soil nutrient retention for N, P and K, as well as increase the balance of soil organic matter [21]. Soil enzymes are a key indicator of soil quality in crop production systems and are involved in biochemical processes of nutrient cycling [22]; moreover, biochar-amended soil showed advantages in improving soil quality and retaining nutrients, increasing plant growth [23]. Due to these beneficial characteristics, the addition of biochar increased the rice yield, as reported in several studies [24,25].…”

Water-saving irrigation occasionally causes an inconsequential yield loss in rice; thereby, biochar incorporation in this context has great scope due to its properties, including the release of nutrients and improving soil physicochemical properties. An experiment was conducted to investigate the effect of biochar combined with fertilizer on physiological response, water and nutrient efficiency of rice and changes in biochemical properties of soil under AWD (alternate wetting and drying) irrigation system. Two types of irrigation practice, such as AWD and CF (continuous flooding), and four types of fertilizer combination, namely T1: 25% Rice husk biochar (RHB) + 75% of recommended fertilizer dose (RFD); T2: 25% oil palm empty fruit bunch biochar (EFBB) + 75% of RFD; T3: 100% RFD; and T0: 0% biochar and fertilizer, were assigned to assess their impacts. The AWD irrigation produced a sharply reduced grain yield (210.58 g pot−1) compared to CF irrigation (218.04 g pot−1), whereas the biochar combination treatments T1 and T2 produced greater yields (260.27 and 252.12 g pot−1, respectively), which were up to 12.5% higher than RFD. Within AWD, irrigation water usage by T1 and T2 (98.50 and 102.37 g L−1, respectively) was profoundly reduced by up to 28.8%, with improved water use efficiency (WUE). The main effect of biochar treatment T1 and T2 also increased photosynthesis rate during vegetative and maturing stage (up to 17.6 and 24.4%, respectively), in addition to boosting agronomic efficiency of nitrogen (N), phosphorous (P) and potassium (K) compared to RFD (T3). Nevertheless, T1 and T2 significantly enhanced the total carbon and nitrogen; dehydrogenase and urease enzyme activities also increased in both irrigation regimes. The results reveal that the integrated application of RHB and EFBB with fertilizer in the AWD regime significantly reduces irrigation water usage and improves nutrient use efficiency, WUE and soil biochemical properties with a minimum yield penalty for rice.

“…Soil enzymes driven by microorganisms are the key indicators for several biochemical processes in soil (Caldwell, 2005;Riah et al, 2014). They play an important role in mineralization and transformation of organic matter and nutrient recycling in soil, energy transformation, stability in soil structure, nitrogen fixation, disease control, and other biochemical transformations such as ammonification, nitrification and phosphorus solubilization leading to increased vigour, growth and productivity of crop (Prasad Reddy et al, 1984;Husain et al, 2003;Karas et al, 2018;Jat et al, 2021).…”
