“…Soil is a life-supporting natural resource which accomplishes diverse functions that are crucial for sustainable crop production [1,2]. The physicochemical properties of soil, viz., pH, bulk density (BD), porosity, total organic carbon (TOC), total nitrogen (TN), C:N ratio, and texture are key indicators of fertility and physical stability of soil [3].…”

A study to assess the profile distribution of important soil attributes in Alfisols and Entisols of West Bengal was conducted during 2016-17. Purposefully selected random sampling was carried out to collect the soils from different locations of two study sites, viz., Kalinagar (25º27'33.9"N, 88º19'10.2"E) from Malda district and Durganagar (26º09'62.7"N, 89º53'51.7"E) from Cooch Behar district of West Bengal at 0-15, 15-30, 30-45 and 45-60 cm depths. Understanding of vertical distribution of soil fertility indicators like soil organic carbon (SOC), total nitrogen (TN) and other important properties in two different soil and climatic conditions will provide an insight regarding the behaviour of soil with the change in environmental conditions. Soil bulk density (BD), porosity, pH, SOC, TN, C:N ratio and texture were determined using standard laboratory procedures and computations. Obtained results were subjected to statistical analyses. Soils of Kalinagar sites were slightly acidic in nature while soils of Durganagar were neutral in nature. Kalinagar soils were silt clay loam in texture where Durganagar soils classified as loam to sandy loam. Soil BD values increased with depth in both Kalinagar (Alfisol) and Durganagar (Entisol). The porosity percentage IJECC, 10(1): 62-73, 2020; Article no.IJECC.54438 63 progressively decreased with an increase in depth. Soils of Durganagar reported higher soil porosity at all the depths studied. An increase in soil pH with increasing depth was observed in both the sites. The mean total organic carbon (TOC) content recorded maximum in surface soil and its concentration decreased with the depth. Kalinagar soils observed 7.63% higher TOC (17.94 g kg -1 ) content than Durganagar (16.57 g kg -1 ) at surface depth (0-15 cm) and its accumulation at the lower depths was also maximum in former soil. Mean TN values were also found to decrease by increasing the depth. The accumulation of total nitrogen at the subsequent depths was relatively higher in Kalinagar than Durganagar. Increase in C:N ratio with increasing depth was noticed in Kalinagar site but the opposite trend was accorded in case of Durganagar. Accumulation of SOC and TN throughout the soil depth was found to be greater in Alfisol (Kalingar) due to higher clay and silt fractions as compared to Entisol (Durganagar). There was a significant positive relation of TOC with clay and silt (r = 0.285, p<0.05, r = 0.314, p<0.01, respectively) and of TN with clay and silt (r = 0.328, p<0.01, r = 0.262, p<0.05, respectively) irrespective of soil orders. Alfisols with high bulk density have a greater capacity to accumulate SOC and TN throughout the soil profile due to higher clay and silt fractions in comparison to Entisols with loose textural properties.

“…Despite several advantages, chemical fertilizers and pesticides are unfriendly to the environment, causing damage to soil, plant, animal, and human health and also placing an economic burden on farmers. Indiscriminate application of synthetic fertilizers interrupts sustainability and environmental quality, while the reduction of organic matter application causes adverse impacts on soil health (Sarkar et al, 2017a;Ferdous et al, 2020). Loss of soil fertility is accompanied by decreased soil aggregation, water-holding capacity (WHC), biodiversity and crop stress tolerance (Sergaki et al, 2018).…”

A majority of agricultural activities are conducted under fragile lands or set-up. The growth and development of crops are negatively affected due to several biotic and abiotic stresses. In the current situation, research efforts have been diverted toward the short-term approaches that can improve crop performance under changing environments. Seed treatment or priming technology is in a transition phase of its popularity among resource-poor farmers. Suitable policy intervention can boost low-cost techniques to implement them on a larger scale in developing countries and to harness the maximum benefits of sustainable food production systems. Primed seeds have high vigor and germination rate that help in seedling growth and successful crop stand establishment under stress conditions. This review is attempted to assess different seed priming techniques in terms of resource use efficiency, crop productivity, cost–benefit balance, and environmental impacts. Moreover, a comprehensive study of the mechanisms (physiological and biochemical) of seed priming is also elaborated. A detailed examination of the applications of priming technology under diverse agroecosystems can improve our understanding of the adaptive management of natural resources.

“…Agroecosystems (which covers $40% of the terrestrial ecosystems) are one of the major planetary ecosystems supporting various services and functions for humanity and underpins realization of important United Nations Sustainable Development Goals and their targets set for the year 2030 (Power, 2010;Dubey et al, 2021a). However, agroecosystems over the preceding decades have suffered immensely in terms of intense farm practices, excessive inputs (agrochemicals/ pesticides), and overuse of critical natural resources (soil, land, and water) (Sarkar et al, 2017a). The credits of agrochemicals in increased food production and feeding the rapidly growing human population is enormous, but at the same time, their debits, such as contamination of the environment, food poisoning, and serious health issues cannot be neglected (Aktar et al, 2009;Carvalho, 2017).…”

Organic interventions conferring stress tolerance and crop quality in agroecosystems during the United Nations Decade on Ecosystem Restoration

Excessive use of synthetic chemicals in conventional agriculture largely degraded the agroecosystems that constitute approximately 40% of the global terrestrial ecosystems. Moreover, changing climate resulted in a substantial loss in agricultural productivity (both in quantity and in quality) mainly due to diverse abiotic and biotic stresses. This draws public awareness about depleting natural resources, viz., soil, land, and water due to unsustainable agricultural practices and equivalently concerns for food-related animal and human health risks. Modern organic agriculture has shown positive impacts in terms of food/biomass production, climate resilience, soil health, biodiversity, nutritional security, and good quality of life; and is of prodigious demand for nutrient-rich organic food products. In the ensuing decade, owing to the principal focus for the quality aspects or health benefits of organic agriculture, this review explores how organic interventions affect the nutritional value and yield quality in a production system; enable plants to adapt to adverse futuristic environmental conditions, and address the global food and nutritional security challenges. The chronological emergence, current global status, public perceptions, and key components of organic agriculture with their attached health benefits are inextricably synthesized herein. Fostering the ethos of organic agriculture under the UN Decade on Ecosystem Restoration (2021-2030) is highly imperative for agroecosystem restoration and its sustainable management. Moreover, the multidimensional paybacks of organic agriculture help in attaining important global goals and targets such as the Bonn Challenge and United Nations Sustainable Development Goals (UN-SDGs) by the year 2030. Therefore, invigorating the escalation of organic farming as a concurrent strategy of soil, land, and ecosystem restoration is the need of the hour.
