“…Soil management in Brazilian states: comparative analyzes of Physical andMonetary Soil Nutrient Balance in 2005 and2015 The comparative analysis between the years reveals a 55% increase in the total NPK balance. Among the states, Rio Grande do Sul showed a greater increase, about 81%, followed by Paraná (56%) and Mato Grosso (53%).…”

Intensive agricultural production tends to stimulate the outflow of nutrients from the soil, requiring producers to properly manage the soil to avoid reducing fertility in the following crops. Thus, the objective was to estimate the annual monetary balance of nutrients in the soil of six Brazilian states that present the highest consumption of inorganic fertilizers in the years 2005 and 2015. The Annual Balance of Nutrients in Soil was used to calculate the physical and monetary balance of nutrients, in the main crops of these States, by quantifying the export of N, P, K from the soil by plants and the insertion of nutrients, through the application of fertilizers, fertigation, and biological fixation. The monetary balance of N, P and K added for the six states was positive and increased by 114% between 2005 and 2015, however, the balance of P for the state of Paraná was negative in 2015 reaching R$ 1,769.17. The balances and Mato Grosso, Rio Grande do Sul, and Paraná were higher concerning Goiás, São Paulo, and Minas Gerais. Except for Paraná, related to P, there was no positive depreciation of the associated NPK nutrients. The different flows, in the comparison among states, are caused by the different dynamics of land use, mainly in the size of the corn and soybean cultivation area.

“…More recently, N-P-K analysis became the basis of several historical nutrient balances studies embracing most input and output processes. These have been applied at spatial scales from villages or parishes 11 – 13 to countries 14 or even to the globe 15 . In general, the agroecosystem is analyzed as a whole, comprising all land uses in a given region, but some studies have focused on just one crop 16 or crop rotation 17 .…”

Agricultural nutrient balances have been receiving increasing attention in both historical and nutrient management research. The main objectives of this study were to further develop balance methodologies and to carry out a comprehensive assessment of the functioning and nutrient cycling of 1950s agroecosystems in Portugal. Additionally, the main implications for the history of agriculture in Portugal were discussed from the standpoint of soil fertility. We used a mass balance approach that comprises virtually all nitrogen (N), phosphorus (P) and potassium (K) inputs and outputs from cropland topsoil for average conditions in the period 1951–56. We found a consistent deficit in N, both for nationwide (−2.1 kg.ha−1.yr−1) and arable crops (−1.6 kg.ha−1.yr−1) estimates, that was rectified in the turn to the 1960 decade. P and K were, in contrast, accumulating in the soil (4.2–4.6 kg.ha−1.yr−1 and 1.0–3.0 kg.ha−1.yr−1, respectively). We observed that the 1950s is the very moment of inflection from an agriculture fertilized predominantly through reused N in biomass (livestock excretions plus marine, plant and human waste sources) to one where chemical fertilizers prevailed. It is suggested that N deficiency played an important role in this transition.

“…Tello et al [12] and Marull et al [13,14] have used SEM approaches to comprehensively study the evolution of land use changes and effects on local biodiversity. Also, flows of nutrients have been traced through agro-ecosystems to better understand issues of soil fertility [15][16][17][18]. Still, a vitally important aspect of (pre-industrial) socio-ecological systems has been widely under-researched.…”

This paper takes a Long-Term Socio-Ecological Research (LTSER) perspective to integrate important aspects of social inequality into Socio-Ecological Metabolism (SEM) research. SEM has dealt with biophysical features of pre-industrial agricultural systems from a largely apolitical perspective, neglecting social relations and conditions of peasant production and reproduction. One of the politically and economically most important manorial systems in Early Modern Austria (Grundherrschaft Grafenegg) serves as a case study to reconstruct the unequal distribution of central resources between ruling landlords and subjected peasants. We show that peasant land use systems generated small surpluses only, whereas landlords enjoyed significant economies of scale. Furthermore, we explore what these conditions of landlord surplus and peasant scarcity implied for their respective agro-ecological sustainability. Finally, we argue that within pre-industrial agrarian systems sustainability costs of inequality were severely limiting margins for agricultural intensification and growth of peasant economies.
