“…Ongoing global climate change has a complicated nature that influences local, national, and regional conditions with economic, social, and environmental consequences [2]. Climate change is considered a worldwide hazard that affects crop productivity and food security [3][4][5][6], as well as soil, water, and energy resources [7][8][9][10], the overall bioeconomy [11,12], and our ability to fulfill the United Nations' Sustainable Development Goals [13][14][15][16]. The rising average global temperature and more frequent extreme thermal events are major concerns with climate change [17].…”

Increased heat stress is a common feature of global climate change and can cause adverse impacts on crops from germination through maturation and harvest. This review focuses on the impacts of extreme heat (>35 °C) on plants and their physiology and how they affect food and water security. The emphasis is on what can be done to minimize the negative effects of heat stress, which includes the application of various materials and approaches. Nano-farming is highlighted as one promising approach. Heat is often combined with drought, salinity, and other stresses, which together affect the whole agroecosystem, including soil, plants, water, and farm animals, leading to serious implications for food and water resources. Indeed, there is no single remedy or approach that can overcome such grand issues. However, nano-farming can be part of an adaptation strategy. More studies are needed to verify the potential benefits of nanomaterials but also to investigate any negative side-effects, particularly under the intensive application of nanomaterials, and what problems this might create, including potential nanotoxicity.

“…Carbon, as the predominant elemental constituent of soil organic matter, exerts a substantial influence on the physical, chemical, and biological characteristics of soil, hence impacting the productivity of soil biomass. Carbon sequestration offers a multitude of ancillary advantages, encompassing the mitigation of climate change, enhancement of ecosystem health, promotion of food security, and facilitation of agricultural profitability [1].…”

“…Soil organic carbon (SOC) plays a crucial role in the global carbon cycle, as the highest layers of soil are believed to possess around three times the amount of carbon present in the entire atmosphere [3]. It is imperative to ensure that the soil organic carbon (SOC) levels in the root zone remain above the designated threshold of 1.5-2.0% in order to preserve the proper functioning of diverse soil processes [1,4].…”

“…Soil carbon sequestration offers various other advantages, encompassing enhanced ecological well-being, bolstered food security, and increased agricultural profitability. The implementation and promotion of site-specific sustainable farming practices, such as conservation tillage and cover cropping, have the potential to enhance both crop and pasture productivity while simultaneously mitigating soil carbon losses [1,6].…”

Depending on the type of agricultural use and applied crop rotation, soil organic carbon accumulation may depend, which can lead to less CO2 fixation in the global carbon cycle. Less is known about organic carbon emissions in different crop production systems (cereals, grasses) using different agrotechnologies. There is a lack of more detailed studies on the influence of carbon content in the soil on plant productivity, as well as the links between the physical properties of the soil and the absorption, viability, and emission of greenhouse gases (GHG) from mineral fertilizers. The aim of this study is to estimate the long-term effect of soil organic carbon sequestration potential in different crop rotations. The greatest potential for organic carbon sequestration is Norfolk-type crop rotation, where crops that reduce soil fertility are replaced by crops that increase soil fertility every year. Soil carbon sequestration potential was significantly higher (46.72%) compared with continuous black fallow and significantly higher from 27.70 to 14.19% compared with field with row crops and cereal crop rotations, respectively, intensive crop rotation saturated with intermediate crops. In terms of carbon sequestration, it is most effective to keep perennial grasses for one year while the soil is still full of undecomposed cereal straw from the previous crop. Black fallow without manure fertilization, compared to crop rotation, reduces the amount of organic carbon in the soil up to two times, the carbon management index by 2–5 times, and poses the greatest risk to the potential of carbon sequestration in agriculture.

Management can affect soil quality through changes in carbon (C) stock, especially in protected C fractions of soil aggregates. Soil aggregation and C sequestration may be improved with soil correction (liming and gypsum) and nitrogen (N) fertilization, but it is not clear how these factors might interact to affect humic substances. The objective of the study was to evaluate the effects of calcium (Ca), magnesium (Mg), and N fertilizatilizer amendments on the accumulation of C, N, and humic substances in soil aggregates from an Oxisoil in Brazil. The production system was no‐till soybean [Gycine max (L.) Merr] double‐cropped with maize (Zea mays L.) and intercropped with forage grass since 2016. Treatments were no amendment, lime only, and lime + phosphogypsum, factorially arranged with and without annual N fertilization of maize. Soil was collected at 0–10, 10–20, 20–40, and 40–60 cm 6 years after initiation of the experiment. The combination of lime, gypsum, and N led to 13% greater total C stock and 20% greater total N stock within the 0–60 cm soil profile than the control. Levels of fulvic acid (FA) and humic acid (HA) were similar among aggregate classes, but humin was greatest in larger aggregates. Liming plus N decreased FA and HA, but gypsum application mitigated this negative effect. Application of limestone, gypsum, and N increased humin, mainly in the soil surface (0–10 cm). Soil C storage and stabilization was enhanced in large soil aggregates with the combined use of lime, gypsum, and N fertilization in humid tropical soils.
