“…Good fodder production can minimize soil erosion compared to conventional crop cultivated areas and grazing animals may increase the soil erosion and sediment deposited like urine, faeces of animals , and other wastes in the water bodies' impact on water quality. Human population pressure, untreated wastewater, poverty, erratic precipitation, and loss of biodiversity are severely causing the deterioration of water quality around rivers (43). Nitrogen and phosphorus are primary concerns, as its higher NO3concentration in the drinking water causes methemoglobinemia (blue baby disease) and excess PO4 3-.…”

Change in precipitation patterns and increase in the frequency and intensity of extreme weather events (high temperatures and heat waves) harm crop productivity. As per the future prediction, the temperature may increase by 2.5 0C by 2050 and by 2-30 C by the end of the century. The present review evaluates the impact of a rise and fall in temperature, solar radiation, and CO2 on the productivity of maize and other crops. Agronomic management practices during the crop growth period of selecting crop cultivars, date of sowing, plant population, dosage, timing, and methods of application of inputs are influenced by temperature, rainfall, solar radiation, and CO2 concentration in the atmosphere. Overall crop productivity will reduce by 50.9 % in wheat in the USA, 46% in maize in China,17% in cotton in India, and 30% in sugarcane in India. Changing the sowing date and adopting improved early and short-duration varieties of corn and other crops are becoming significant under low-cost adoption technologies to mitigate climate change. Info Crop-SORGHUM simulation model predicts that change in the sowing date of a variety in sorghum reduces the impact of climate change and vulnerability to 1- 2 % by 2020, 3-8 % by 2050, and 4-9% by 2080. The review highlights the impact of heat stress and drought on soil processes, and overall soil health. The authors conclude to implement climate adoption technologies based on Agriculture 4.0 to sustain crop production globally.

“…It is the basic and nutritious staple food of the world. However, due to an imbalance in the 6Ps (population, poverty, pollution, precipitation, periodicity and plantation) and/or an increase in environmental stress, the present civilization is facing high challenges for sustaining soil fertility, mitigating water demand and achieving optimum agricultural production (Mariya et al 2019). To alleviate these challenges, researchers are looking towards nanotechnology, an emerging field of science, to understand and regulate nutrient application in agriculture on a nanoscale (1-100 nm) coupled with developing nano-fertilizers for sustainable agriculture.…”

Zinc oxide nanoparticles (ZnONP) were synthesized and characterized using SEM, EDAX, DLS and UV-Vis spectra. Its use as a nanofertilizer as an alternative to conventional zinc sulphate (ZnSO 4 .7H 2 O) was evaluated in five Zn-deficient soils with a variable pH range (7.2-8.7). For this, the carbon of the soil microbial biomass (SMBC), the bacterial population, the nutrient dynamics and the biometric parameters of the wheat crop were assessed. The varying dosages (0, 100, 200 and 500 mg/L), sizes (30-100 nm), and the spherical shape of ZnONPs were evaluated in comparison to ZnSO 4 .7H 2 O levels. Results showed the maximum SMBC and bacterial population at 100 mg/L of ZnONPs but a sharp decline at higher concentrations. In addition, soil application of ZnONPs at 5 mg/kg produced a higher root elongation (4.3-8.8%), shoot elongation (3.5-4.0%), total chlorophyll (4.9-5.6%), grain yield (1.7-2.3%) and grain Zn-content (1.6-2.1%) in comparison to the conventional ZnSO 4 .7H 2 O at 10 mg/L. ZnONPs at 100 mg/L produced a higher soil microbial biomass carbon (3.9-4.6%), bacterial population (7.2-9.0%), germination (22%) and grain Zn-content (17.9-20%) as compared to the conventional ZnSO 4 .7H 2 O at 0.5%. The higher grain Zn-contents could be attributed to the small size and high surface area of ZnONPs resulting in easy entry into the plant system either through root or foliar by penetrating the pores present in the cell membranes. Conversely, the conventional ZnSO 4 .7H 2 O, due to its larger size and higher solubility as compared to ZnONPs, has low retention in plant systems, high surface run-off and low fertilizer efficiency. Thus, the authors concluded to apply spherically synthesized ZnONPs (average size-36.7 nm) at 5 mg/kg in the soil application and 100 mg/L in the foliar application for maintaining SMBC and bacterial population, improving total chlorophyll, and grain Zn-contents and overall sustaining wheat production in Zn-deficient neutral and alkaline soils.

“…Geographic information system mapping techniques reveal saltwater intrusion, paleo‐salinities, water–rock interaction, and overexploitation of groundwater in coastal areas (Mastrocicco & Colombani, 2021). Population, poverty, pollution, precipitation, periodicity, and plantation (popularly called 6‐Ps) are responsible for degrading soil and water ecosystems (Mariya et al., 2019). Globally, salinity and sodicity are increasing at a rate of 1–2% per year.…”

A continuous decline in soil organic C (SOC) and an increase in salt‐affected areas are a challenge to future sustainability. We searched on the scientific databases of Web of Science, Scopus (Elsevier) database, and Google. We reviewed 101 studies of the last 25 yr with the following keywords: drip irrigation, fertigation system, liquid biochar, liquid organic, organic fertigation, saline‐sodic soils, and salinization. Our objectives were to identify knowledge gaps to direct future organic research and assess the effect of organic amendments on meeting the plant's N, P, and K requirements in saline‐sodic soils. The review showed that organic fertigation systems reduce salt concentration in irrigation water and inhibit glutamine synthetase by N‐fixing diazotrophs. The system increases photosynthetic activities in plants, microbial biomass C, bacterial colonization, plant–mycorrhizal association, and phospholipid‐derived fatty acids from microbes. It increases essential soil nutrients, including SOC; increases salt/water stress tolerance; and reduces Na+ ion toxicity in plants by regulating abscisic acid pathways in saline‐sodic soils. It creates a conducive environment for phosphatase, dehydrogenase, urease, protease, α‐amylase, and gibberellins. This review sketches the role of silicic acid, salicylic acid, and liquid organics in plant growth mechanisms: enhanced photosynthesis, increased salt/water tolerance, and reduced Na+ toxicity. It suggests novel strategies to develop a task force to promote a community–corporate farming system to adopt cost‐effective green technologies for bioresource regeneration, diverse market production, and social capital generation. We develop a synergy between organic fertigation system and community–corporate farming to bring much‐needed agricultural sustainability.
