“…Thus, it require large quantities of N for optimal growth and yield. Shafi et al (2007) also reported increased maize yield with the application of N fertilizer. Maize starts to take up N rapidly at the middle of vegetative growth period and maximum N uptake occur near silking stage (Hanway, 1963).…”

Abstract:The magnitude of yield reduction due to soil compaction is variable and depends on the soil type, fertility status and other soil and environmental factors. The present investigation was carried out at the research farm, Department of Soil Science, Punjab Agricultural University, Ludhiana. The experiment was conducted to evaluate the effect of different levels of subsoil compaction and nitrogen fertilization on maize phenology, yield and heat use efficiency ) treatment during the year 2012 and 2013, respectively. The tasseling and silking stage was delayed, while physiological maturity was advanced under C 2 subsoil compaction treatment than that in C 0 treatment. The N 2 treatment improved the yield by 14.9 and 13.9 % and HUE by 15.2 and 14.3 % than that in N 0 treatment during the year 2012 and 2013, respectively. Maize took more days to reach physiological maturity under N 2 treatment as compared to N 0 treatment. Phenothermal index (PTI) showed that crop reached different stages earlier under C 1 and C 2 than that of C 0. The data emphasized the need to take care of soil strength and soil temperature related parameters along with weather conditions for better yield prediction using thermal time.

“…The results showed that the maizelegume treatment required a low amount of nutrients and also improved the soil fertility through recycling of the plant biomass. Researchers have demonstrated a number of ways of incorporating N fixing grain legumes into cropping system (Mpepereki et al 2000), as well as FYM/compost application to increase availability of N to cereal crops (Murwira 1994;Chikowo et al 2004;Shafi et al 2007). …”

On-farm runoff plots were established during 2004 and monitored for 4 years in the Pokhare Khola watershed (Nepal) in a completely randomized design with four replications of each three treatments: traditional Farmer Practice (FP) (Zea mays-Eleusine coracana), Reduced Tillage (RT; Z. mays-Vigna ungeuculata), and Commercial Vegetable with double dose of farm yard manure (CV; Z. mays-Capsicum species) to evaluate treatment effects on soil nutrient losses, nutrient balances and crop income on Bari land (rainfed terraces). Nutrient removal due to crop harvest was found to be significantly higher than nutrient loss through soil erosion, and CV treatment exhibited a significantly higher N uptake (123 kg ha -1 year -1 ) through crop harvest than other treatments. Moreover, the CV treatment produced significantly higher income per unit area of Bari land than the other treatments. Soil organic carbon and major nutrients losses (NPK) through soil erosion were minimal [25.5 kg ha -1 year -1 soil organic carbon (SOC) and 5.6:0.02:0.12 kg ha -1 year -1 nitrogen (N), phosphorus (P), potassium (K), respectively]. Result showed that no nutrients were lost through leaching. Nutrient losses due to soil erosion and runoff were lower than previously reported in the Middle Mountain region, indicating a need to re-evaluate the soil erosion and nutrient loss problems in this region. Interventions such as reduced tillage and double dose of FYM with vegetable production were found to be effective in maintaining soil fertility and increasing farm income compared to the traditional maize-millet production system. The nutrient balance calculations suggest that integrated nutrient management techniques such as residue incorporation and application of FYM with a minimum application of chemical fertilizer are potentially sustainable production approaches for the Mid-hills of Nepal.

“…Aunque el nivel medio de este pará-metro es ligeramente superior en superficie, no existen diferencias significativas con las muestras tomadas a 15-30 cm. Incrementos en el contenido de materia orgánica son esenciales para garantizar una rehabilitación real de los suelos, ya que es una propiedad íntimamente relacionada con las mejoras en la estructura del suelo, aireación, retención y circulación de agua, reducción de las tasas de erosión, estimulación de las poblaciones microbianas y en incrementos en la fertilidad por liberación de nutrientes (Smith et al, 1993;Bukert et al, 2000;Shafi et al, 2007). La tendencia habitual del Corg, sobre todo en ambientes áridos y semiáridos, es la mineralización, de manera que una sola aplicación de estiércol porcino debería conducir a una ligera reducción en el contenido de Corg del suelo a medio y largo plazo (Zornoza et al, 2012).…”

Zornoza, R. et al., 2017. Rehabilitación de una presa de residuos mineros mediante la aplicación de lodo de mármol y purín de cerdo para el desarrollo de una fitoestabilización asistida. Boletín Geológico y Minero, 128 (2) RESUMENLas acumulaciones de residuos mineros abandonados presentan riesgos ambientales y de salud pública por la potencial transferencia de metales pesados tóxicos a través de la erosión hídrica y eólica o lixiviación. Para reducir estos riesgos, se ha desarrollado una estrategia de rehabilitación en una presa de residuos mineros basada en la fitoestabilización asistida. A lo largo de 2011 se aplicó sobre la superficie de la presa lodo de már-mol (6.7 kg m -2 ), purín de cerdo (1.7 ,7 L m -2 en julio y 2.6 L m -2 en septiembre), y la fase sólida de purín de cerdo (7 kg m -2 ). En primavera de 2012 se introdujeron trece especies vegetales autóctonas. Durante dos años (2012-2013) se ha monitorizado con carácter semestral la evolución de diferentes propiedades edáficas y la fracción biodisponible de los metales Cd, Pb y Zn. Los resultados mostraron un incremento en el pH (de ~3 a ~7), la estabilidad de agregados (de 7% a 10-15%), el carbono orgánico (de 3.5 g kg -1 a 3.5 g kg -1), el nitrógeno total (de ~0.3 g kg -1 a ~0.8 g kg -1) y la capacidad de intercambio catiónico (de 6 cmol+ kg -1 a 11 cmol+ kg -1 ) con la aplicación de las enmiendas y el desarrollo de la vegetación, mientras que la fracción biodisponible de los metales descendió drásticamente (90-99%). Por tanto, la estrategia seguida ha resultado positiva para reducir la biodisponibilidad de metales pesados, mejorando la calidad y fertilidad del suelo. Estos resultados son prometedores en áreas donde se generen residuos que puedan ser utilizados para la rehabilitación de suelos afectados por metales pesados, revalorizando los mismos y al convertirse en subproductos de utilidad.Palabras clave: Presa de residuos, enmiendas, geoquímica, metales pesados, minería.
