“…Statistical analysis shows total soil N correlates with C org and sulfur, indicating that these elements are mainly bound in the organic matter fraction of soils. The content in soil sulfur (S) varied between 0.06 and 1.40 g kg 21 , (mean 0.4 g kg 21 ), whilst the respective amount of S in non cultivated mountainous areas in Greece was on average 1.7 g kg 21 (Karyotis et al, 2006). These differences indicate that sulphur content is affected mainly by factors related to topography (Roberts and Bettany, 1985).…”

Twenty-seven soil samples were collected from surface horizons, in order to include representative soil types. Three samples per site were taken and mixed from the examined area, in spring 2005. The study area occupies 820 ha of the now-drained (1910), partially levelled, and continuously farmed Lake Askuris in Greece. The area, which is close to the village of Kalipefki (Longitude: 22u 279 220 E; Latitude: 39u 579 390 N) and to Mount Olympus, is elevated (<1000 m) with a Mediterranean climate of mild, rainy winters and hot, dry summers. In addition to clay content, the soils were chemically characterized using 22 soil chemical tests, including pH, total carbon and organic matter, total nitrogen, total sulphur, exchangeable cations, cation exchange capacity, organic and extractable phosphorus (P), and pseudo-total and diethylenetriaminepentaacetic acid (DTPA) extractable trace elements. All of the soil data were skewed, with population mean values higher than the median for clay percentage, cation exchange capacity, carbon/nitrogen ratio, exchangeable calcium (Ca) and magnesium (Mg), DTPA iron (Fe), and total zinc (Zn). A geographic information system and kriging was used to prepare spatially explicit maps (at least two or three level of fertility) for the exchangeable basic cations, the trace elements, phosphorus, organic matter, total nitrogen (N), and total sulfur (S). It is expected these contemporary baseline data will assist the local community and farmers as they consider future nutrient management plans along with other land use options that could include re-flooding the lake bed.''

Agriculture is among the main causes of water pollution. Currently, 75% of global anthropogenic nitrogen (N) loads come from leaching/runoff from cropland. The grey water footprint (GWF) is an indicator of water resource pollution, which allows for the evaluation and monitoring of pollutant loads (L) that can affect water. However, in the literature, there are different approaches to estimating L and thus contrasting GWF estimates: (A1) leaching/runoff fraction approach, (A2) surplus approach and (A3) soil nitrogen balance approach. This study compares these approaches for the first time to assess which one is best adapted to real crop production conditions and optimises GWF calculation. The three approaches are applied to assess N-related GWF in barley and soybean. For barley in 2019, A3 estimated a GWF value 285 to 196% higher than A1, while in 2020, the A3 estimate was 135 to 81% higher. Soybean did not produce a GWF due to the crop characteristics. A3 incorporated N partitioning within the agroecosystem and considered different N inputs beyond fertilization, improving the accuracy of L and GWF estimation. Providing robust GWF results to decision-makers may help to prevent or reduce the impacts of activities that threaten the world’s water ecosystems and supply.

“…Estudios han mostrado diferencias entre la mineralización neta de N para la misma enmienda en suelos de distinto origen (Thomsen y Olesen, 2000;Huang y Chen, 2009;Karyotis et al, 2006;Mubarak et al, 2010). Estas diferencias pueden ser atribuidas a propiedades como: textura (con énfasis en contenido de arcillas), capacidad de retención de humedad, pH, salinidad, contenido de materia orgánica, concentración de nutrientes y actividad microbiana.…”

Factores que intervienen en el proceso de mineralización de nitrógeno cuando son aplicadas enmiendas orgánicas al suelo. Una revisión RESUMENLa aplicación de enmiendas orgánicas es una práctica que se hace regularmente en sistemas de cultivos, con el fin de mejorar propiedades físicas y químicas del suelo y aportar nutrientes como nitrógeno (N). Para que las plantas puedan absorberlo, gran cantidad del N que es aportado a través de las enmiendas orgánicas, debe ser transformado de sus formas orgánicas a inorgánicas, en un proceso denominado mineralización. Se han desarrollado investigaciones tendientes a entender este proceso, y, cómo el aporte de enmiendas orgánicas influye en su dinámica. Esta revisión proporciona una visión global sobre los factores, de suelo y enmienda, que intervienen en el proceso de mineralización de N cuando se aplican al suelo enmiendas orgánicas de diferentes fuentes.Palabras clave adicionales: inmovilización, lixiviación, abono orgánico. ABSTRACTThe application of organic amendments is a practice that is done regularly in crop systems in order to improve the physical and chemical properties of the soil and provide nutrients such as nitrogen (N). In order for plants to absorb it, much of the N that is contributed through organic amendments must be transformed 1 Facultad de Ciencias Agrarias, Programa de Maestría en Ciencias Agrarias, Línea Suelos y Aguas, Universidad Nacional de Colombia, Bogotá (Colombia).
