This paper presents a binary soil capability classification System which bas been developed and used in Québec since 1958. The system bas been designed to provide some basic and essential information, regarding the value of the soil, to be integrated in a broad agricultural and economic survey of the region. The basic criteria of the present system are : 1. the fundamental value of the soil determined by the characteristics of the soil profile ; and, 2. the kind and importance of management practices required, v.g. : correction of unfavourable internal or external limitations ; or, indications for a restricted use of the land such as : permanent pasture, wildlife, recreation and forestry. In this system, the capability class is derived by integrating these two variables ; or, in other words, the class is the result of the combination of these two fundamental criteria. The close relation between these two factors or parameters is ex-pressed in the scheme presented in tables I and II for mineral and organic soils respectively. This logical and practical method seems suitable and adaptable to describe any set of landscapes which are of interest to agronomists, economists and regional planning commissions. The regions of Bas-Saint-Laurent, Gaspésie, Iles-de-la-Madeleine and Montréal have been mapped according to this system.

Soil C Sequestration

<p>Reducing greenhouse gas (GHG) emissions in to the atmosphere to limit global warming is the big challenge of the coming decades. The focus lies on negative emission technologies to remove GHGs from the atmosphere from different sectors. Agriculture produces around a quarter of all the anthropogenic GHGs globally (including land use change and afforestation). Reducing these net emissions can be achieved through techniques that increase the soil organic carbon (SOC) stocks. These techniques include improved management practices in agriculture and grassland systems, which increase the organic carbon (C) input or reduce soil disturbances. The C sequestration potential differs among soils depending on climate, soil properties and management, with the highest potential for poor soils (SOC stock farthest from saturation).</p><p>Modelling can be used to estimate the technical potential to sequester C of agricultural land under different mitigation practices for the next decades under different climate scenarios. The ECOSSE model was developed to simulate soil C dynamics and GHG emissions in mineral and organic soils. A spatial version of the model (GlobalECOSSE) was adapted to simulate agricultural soils around the world to calculate the SOC change under changing management and climate.</p><p>Practices like different tillage management, crop rotations and residue incorporation showed regional differences and the importance of adapting mitigation practices under an increased changing climate. A fast adoption of practices that increase SOC has its own challenges, as the potential to sequester C is high until the soil reached a new C equilibrium. Therefore, the potential to use soil C sequestration to reduce overall GHG emissions is limited. The results showed a high potential to sequester C until 2050 but much lower rates in the second half of the century, highlighting the importance of using soil C sequestration in the coming decades to reach net zero by 2050.</p>

To achieve the optimal and diverse utilization of cotton (Gossypium hirsutum) plant residues in various agricultural, industrial, and environmental applications, the chemical composition of cotton biomass tissues across different plant parts (e.g., seed, boll, bur, leaves, stalk, stem, and root) is of essential information. Thus, in this work, we collected field-grown whole mature cotton plants and separated them into distinct biomass fractions including main stems, leaf blades, branches, petioles, roots, and reproductive parts (mid-season growth stage) or bur, peduncles/bract, and seed cotton (pre-defoliation stage). The contents of selected carbohydrates and amino acids in these cotton biomass materials were determined. Both essential and nonessential amino acids were enriched in cotton leaf blades and reproductive parts. The distribution pattern of the selected carbohydrates differed from that of amino acids—higher contents of carbohydrate were found in roots, main stems, and branches. Although glucose was the most abundant non-structural carbohydrate in cotton plant parts at mid-season, xylose was the most abundant in most plant parts at the pre-defoliation stage. Nutritional carbohydrates and amino acids were further accumulated in seeds at pre-defoliation. The information reported in this work would be helpful in exploring and optimizing management practices and processing strategies for utilizing cotton crop biomass materials as valuable and renewable natural resources.

SummaryJalauni sheep are found in the Bundelkhand region of Uttar Pradesh and Madhya Pradesh states in India. About 37% of the geographical area of this region is under cultivation and about 86% of the population, mostly directly or indirectly dependent on agriculture, live in villages. Forests, cultivable waste and barren land occupy more than 50% of the area, permanent pasture and other grazing lands about 9% and miscellaneous tree crops and grasses about 0.7%. The livestock census figures of 1977 and 1997 indicate an annual declining trend of 0.04 % in the sheep population in Uttar Pradesh and Madhya Pradesh states. Characterization and evaluation of Jalauni sheep under field conditions were undertaken to establish the norms, morphological characteristics and performance parameters of this breed. A total of 78 households were visited in 29 villages in five districts. Information on feeding, breeding and management practices, utility patterns etc. and production and reproductive performance was collected through personal observations and interaction with the farmers. Body weight and/or body measurements were recorded for 374 animals. Average adult body weights of male and female Jalauni sheep were 35.5±2.1 and 27.2±0.7 kg respectively. Age at first lambing was 1.5 to 2 years and lambing interval one year. A ewe, on an average, delivers 7–9 lambs in her lifetime.

This paper explains the economic benefits that the country can achieve if improved irrigation management is followed in Bangladesh. The present study has been carried out using data from different studies by different organizations on the existing status of irrigation management practices in Bangladesh. As a result, defects were detected in the system, which are possible to eliminate through taking up various effective measures. A quantitative assessment has been done based on savings to be acquired as a result of eliminations of the defects. An additional amount of US$140 million may be saved from improved irrigation and water management practices, US$543 million from elimination of the present system loss of water and US$155 million by providing supplementary irrigation in the Aman (summer) season. An amount of US$108 million may be saved by enhancing mechanical efficiency of the diesel driven irrigation equipment through proper operation and in time repair and maintenance, US$362 million through proper conservation of water in khal (local drainage channel), beel (small water bodies), haor (comparatively larger water bodies) and pond and US$38 million by controlling unplanned installation of irrigation equipment. The Government of Bangladesh is to spend only an amount of about US$1.74 million for successful implementation of proper irrigation and other management activities, when in total an amount of about US$1,344.26 million may be thus saved and added annually in the economy of Bangladesh. The amount thus saved is about one-fifth of the total Bangladesh Budget for the Fiscal Year of 2002/03 (US$7,570 million) and about one-sixth of the total Bangladesh Budget for the Fiscal Year of 2003/04 (US$8,962 million).

The Da Dang river basin, located in the Upper Part of Dong Nai River, plays a crucial role to protect water resources in the downstream parts. The purpose of this study is to assess and develop a soil erosion map in the Da Dang river basin by using the Revised Universal Soil Loss Equation (RUSLE) combined with remote sensing (RS) and Geographic Information System (GIS). The factors used in the RUSLE equation (R, K, LS, C, and P) were computed by using data obtained from local meteorological stations, topographic maps, soil surveys, and satellite images. The data on water quality (TSS) of 75 surface water samples was deployed at 15 monitoring sites in the river basin in the period of 2012 – 2016, provided by DONRE of Lam Dong. The results showed that 14.41% of the basin area is subjected to a high erosion rate with an extent of 10 tons/ha/year or more. Furthermore, the study also indicated that TSS concentration has a closely correlation with land use practices and the the spatial distribution of soil erosion. These findings are essential information and practical implications for local authorities in formulating provincial planning policy for land use and the management practices of soil and water protection in the Da Dang river basin, a sensitively mountainous area, in the context of climate change.

Abstract Soil chemistry and microbial diversity can impact the vigor and nutritive qualities of plants, as well as plants’ ability to deploy anti-herbivore defenses. Soil qualities often vary dramatically on organic versus conventional farms, reflecting the many differences in soil management practices between these farming systems. We examined soil-mediated effects on herbivore performance by growing potato plants (Solanum tuberosum L.) in soils collected from organic or conventional commercial farm fields, and then exposing these plants to herbivory by green peach aphids (Myzus persicae Sulzer, Hemiptera: Aphididae) and/or Colorado potato beetles (Leptinotarsa decemlineata Say, Coleoptera: Chrysomelidae). Responses of the two potato pests varied dramatically. Survivorship of Colorado potato beetles was almost 3× higher on plants grown in organic than in conventional soils, but was unaffected by the presence of aphids. In contrast, aphid colony growth was twice as rapid when aphids were reared alone rather than with Colorado potato beetles, but was unaffected by soil type. We saw no obvious differences in soil nutrients when comparing organic and conventional soils. However, we saw a higher diversity of bacteria in organic soils, and potato plants grown in this soil had a lower carbon concentration in foliar tissue. In summary, the herbivore species differed in their susceptibility to soil- versus competitor-mediated effects, and these differences may be driven by microbe-mediated changes in host plant quality. Our results suggest that soil-mediated effects on pest growth can depend on herbivore species and community composition, and that soil management strategies that promote plant health may also increase host quality for pests.

SUMMARYSoil organic carbon (C) plays a critical role in supporting the productive capacity of soils and their ability to provide a wide range of ecologically important functions including the storage of atmospherically derived carbon dioxide (CO2). The present paper collates available information on Scottish soil C stocks and C losses and reviews the potential pressures on terrestrial C, which may threaten future C stocks. Past, present and possible future land use, land management practices and land use changes (LUCs) including forestry, agriculture, nitrogen (N) additions, elevated CO2 and climate change for Scotland are discussed and evaluated in relation to the anthropogenic pressures on soil C.The review deduces that current available data show little suggestion of significant changes in C stocks of Scottish soils, although this may be due to a lack of long-term trend data. However, it can be concluded that there are many pressures, such as climate change, intensity of land use practices, scale of LUC, soil erosion and pollution, which may pose significant threats to the future of Scottish soil C if these factors are not taken into consideration in future land management decisions. In particular, this is due to the land area covered by vulnerable peats and highly organic soils in Scotland compared with other areas in the UK. It is therefore imperative that soil C stocks for different land use, management practices and LUCs are monitored in more detail to provide further insight into the potential changes in sequestered C and subsequent greenhouse gas emissions, as advised by the United Nations Framework Convention on Climate Change (UNFCCC).
