Maintaining soil fertility was the most pressing problem in preindustrial agriculture. Prior to the arrival of industrial inputs, farmers relied on ecological soil replenishment processes and biological fertilizing techniques to sustain the productivity of soil. Central European farmers actively managed the cycling of nutrients by keeping livestock. Farm animals provided the means to recycle nutrients from crop production and to transfer nutrients from land-use systems dedicated for biomass extraction, such as grasslands. This article explores the unequal distribution of these vital resources in the Manor Bruck, Austria, and its impact on landlord’s and peasant’s abilities to meet the “land costs” of sustaining soil fertility. The article tests the hypothesis as to whether inequality was a major driver for unsustainable farming practices and the degradation of agro-ecosystems in the long run. Focal points are commons and communal land-use systems and their role in cycling nutrients through the agricultural landscape. Commons in the Manor Bruck comprised vast grasslands, which provided an important ecological buffer to balance the continuous export of nutrients from crop production for all actors. The aim is to demonstrate how social conflict emerging from the competition over commons guides us to the specific sustainability challenges faced by farmers.

This article describes the intensification process of agriculture and its environmental limits regarding soil fertility in the rural community of Fonsagrada, in the inner region of Galicia in northwestern Spain. It addresses changes in land use, crops, and agricultural productivity between 1750 and 1890, framed within the theory of social metabolism and based on the method of nutrient balances. That technique measures nitrogen, phosphorus, and potassium flows across the landscape within a given agro-ecosystem to assess its biophysical functioning and to detect environmental constraints related to management. The intensification of cropland resulted in net losses of potassium in outlying rough grazing land and hay meadows that served as the sources of cropland nutrients. Agricultural intensification was possible due to the close stabling of livestock, which allowed for more manure availability. Doing so, however, deprived pastureland of nutrient recover through manure deposition, which created a metabolic rift in the agro-ecosystem.

Understanding the replacement of soil nutrients removed by harvests makes it possible to understand the influence of humans on long-term soil fertility. This article calculates nitrogen, phosphorous, and potassium balances for cropland in 1920 for three agroecoregions distinguished by particular historical settlement patterns, land use, geography, and climatic characteristics in Catalonia, Spain. The analysis assesses and compares the regional potential for farmers to have returned the nutrients extracted from croplands at a time of transition, when only a few synthetic fertilizers were yet available. From sustainability science, the article borrows a methodology to reconstruct soil nutrient balances in historical agroecosystems from available regional historical sources. The soil balances indicate that nutrient extractions were balanced with the additions in Catalonia’s wetter Pyrenees and eastern regions, but were in deficit in the arid western regions, where less livestock manure was available. In Barcelona province, farmers made considerable use of synthetic fertilizers already in 1920. Such fertilizers were mainly intended to supplement phosphorus in the eastern region, suggesting that they played an important role there too, where there was not enough manure.

This research explains what happened to agricultural soil fertility during the “Campanha do Trigo” (Wheat Campaign) in Portugal, which began in 1929. It is commonly understood that the excessive expansion of wheat crops during the fascist “Estado Novo” (New State) regime led to the degradation of soils in the southern half of Portugal. This relationship, however, has never been questioned before. This article extends the narrative back into the last half of the nineteenth century in search of the origin of processes that gradually intensified throughout the country. In short, expansion of the cultivated area in association with the inadequate intensification of crop rotations over about 80 years, from the 1870s onward, including in non-wheat areas, strongly accentuated soil erosion and made organic fertilization progressively less effective. These transformations were only partially offset by chemical fertilization. Nitrogen and phosphorus were the key factors in this historical process. Focusing on the cultivation system and soil dynamics allows the successive integration of various kinds of historical evidence and sources. From an environmental question—why did agricultural soil degrade?—this article explores soil degradation over time and space, and assesses its social and biophysical impacts. At the same time, it addresses the history of agriculture in Portugal and its disciplinary foundations.

In contrast to most long-settled agricultural landscapes, the US Great Plains presents a rare example of well-documented agricultural colonization of new land. The Census of Agriculture provides detailed information about evolving grassland farm systems from the beginning of agricultural expansion and then at some two dozen time points between 1880 and the present. From early sod-busting, through drought and depression, and into late-twentieth-century modernization, it is possible to track how farmers used their land in any county. Treating farmland as an agroecosystem, a hybrid human-natural landscape, this article asks how farmers captured, altered, and replenished soil fertility. Did they extract more soil nitrogen than they returned, or did they maintain a balance? The article assesses land use from a soil nutrients perspective in several plains environments to capture variation in climate (especially rainfall), native soil quality, and availability of irrigation water. It traces farm management strategies through time to understand agricultural crises, growth periods, and technological transitions in the context of soil fertility. Soil management on an agricultural frontier was markedly different from that in places that had been farmed for centuries. A shortage of people and livestock and an abundance of deep, rich soils in the plains informed farmers’ calculations as they juggled labor, capital, and market forces against family and financial strategies. Uniform methods of estimating and representing soil nutrient processes make possible a direct comparison of the relative sustainability of historical agroecosystems.

Using a socioecological metabolism approach to analyze data from the Census of Agriculture, this article examines the underlying soil fertility of two case study areas in the Canadian province of Saskatchewan through the calculation of soil nitrogen balances. The Rural Municipalities of Wise Creek and Livingston are 300 miles apart and therefore have different topography, soil types, and rainfall levels, even though both are within the northern Great Plains. Over 85 years, from first settlement in the 1910s until the beginning of the twenty-first century, Wise Creek agriculture focused increasingly on livestock production while in Livingston farmers began to grow a greater variety of crops, most notably incorporating canola into rotations. Despite the differences between the two case studies, the pattern of soil nitrogen losses was remarkably similar, with biomass yields declining along with soil nitrogen. The addition of chemical nitrogen fertilizers since the 1960s did not produce yields matching historic highs, nor did a renewed focus on livestock. Wise Creek and Livingston showed two different responses to declining yields, but neither one ultimately provided a long-term solution to the problem of soil nutrient depletion and consequent productivity declines.

Fertile soils are essential for human health and nutrition and formed the foundation of human economies for millennia. Soils deserve close attention from environmental and economic historians and sustainability scientists. Most soil history literature addresses failure: misuse of soil, uncontrolled erosion, and the resulting collapse of past civilizations. More important, however, and of urgent interest for our present and future prosperity, are the mundane ways that historical farm communities sustained soil health, even while cultivating the same land for centuries. This article explains five strategies by which European and North American farmers accessed, recycled, replenished, and sustained soil fertility over 250 years. By evaluating inputs, extractions, transfers, and annual balances of potassium, phosphorus, and, especially, nitrogen, it models historical soil management in a variety of agroecosystems in various geographical settings and through time. This biophysical environmental history, based on socioecological metabolism methods borrowed from sustainability science, reveals ongoing adaptation to shifting social and environmental contexts. As industrialization, global trade, and population accelerated, farmers adjusted their soil fertility strategies to keep up with new pressures and opportunities. Each solution to existing soil fertility constraints created new obstacles and bottlenecks. Through the past quarter millennium, farm sustainability meant constant readjustment to new circumstances. As farmers innovated crop choices and rotations, corralled livestock, adopted new technologies, deployed novel energy sources, and expanded into new lands, they increased food productivity to feed growing world population and supply expanding markets, while maintaining the supply of soil nutrients necessary to fertilize next year’s crop.

What social conditions produce positivism? One position, common to both positivists and some of their major critics, suggests that positivism is an “ideology” or “worldview” of industrial capitalism. Positivism therefore resonates with the basic experience of capitalism for all social groups. Intellectuals draw on this experience in formulating positivist social science. A second position suggests that positivism is a strategy of distinction by which intellectuals attempt to accumulate symbolic capital against their rivals. This position suggests that positivism is a resource for establishing a social science that imitates the methodology of natural science. Our article argues for a third view focused on the internal structure of the intelligentsia as a social group. Positivism could emerge in both industrial capitalist and preindustrial contexts; however, the types of positivism differ in these two cases because the structure of the intelligentsia differs. In preindustrial contexts, such as nineteenth-century Italy, which is the focus of our analysis, positivists claim an ontological continuity between natural and social sciences. In industrial contexts, on the basis of which most theories of positivism rest, positivists claim a methodological similarity between natural and social sciences. We conclude our analysis by reflecting on the implications of our study for work on positivism and social ontology in the social sciences.

We study the relationship between internal migration and industrialization in the United States between 1850 and 1880. We use the Linked Representative Samples from IPUMS and find significant amounts of rural-urban and urban-urban migration in New England. Rural-urban migration was mainly driven by agricultural workers shifting to manufacturing occupations. Urban-urban migration was driven by foreign-born workers in manufacturing. We argue that rural-urban migration was a significant factor in US economic development and the structural transformation from agriculture to manufacturing.

Following the landmark essay of T. H. Marshall, Citizenship and the Social Class (1949), it has conventionally been assumed that the introduction and expansion of social rights in Europe happened as the final stage of a long process of democratization that included the granting of first civil and then political rights. We present a radically different perspective on the relationship between the extension of suffrage (under meaningful competition for government power) and social rights, that is state-financed entitlements that make citizens’ livelihood independent from the labor market in the instance of events such as unemployment or sickness. First, some countries institutionalized a state-financed poor relief system much before mass democratization. In these countries, the primary effect of suffrage extension was to reduce public social spending, not expand it. Second, the way this retrenchment occurred was partly by creating a negative link between social rights, on the one hand, and civil and political rights, on the other. We test our argument with case studies of nineteenth- to early-twentieth-century England, Denmark, Norway, and Prussia, all of which are paradigmatic cases that represent the variation in welfare state types.
