Analytical methods comparison for soil organic carbon determination in Andean Forest of Sangay National Park-Ecuador Acta Agron. (Palmira)
Cargua Catagña,Franklin Enrique; Rodríguez Llerena,Marco Vinicio; Damián Carrión,Diego Armando; Recalde Moreno,Celso Guillermo; Santillán Lima,Guido Patricio.
Abstract A relationship among total organic carbon content determined by ignition loss (LOI) and DUMAS combustion methods, were perfomed in evergreen Andean eyebrow forest soils, southwestern zone of Sangay National Park- Ecuador, where three conglomerates were established as follows: (C) with five plots (P) with plots of 20 x 20 m. In each plot, five digging trenches and four soil samples were carried out at different depths: 0-10, 10-20, 20-30 and> 30 cm, respectively. It is observed that the amount of total organic carbon obtained by the DUMAS and LOI method (R2 = 0.99) does not differ significantly. However, the DUMAS total organic carbon determination methodology showed greater precision with regard to LOI, thus becoming a good alternative to be...

Estimation of carbon stocks under different soil uses in the central highlands of Mexico Acta Agron. (Palmira)
Álvarez-Arteaga*,Gustavo; García-Fajardo,Belina; Orozco-Hernández,María Estela; Mireles-Lezama,Patricia; Contreras-Martínez,Julieta.
Abstract The loss of organic carbon stocks from the soil and their expulsion into the atmosphere due to the effect of anthropogenic activities must be understood as a problem that goes beyond the environmental to the social and economic context, with the soil degradation being just one of its many impacts. While the accumulation of carbon in the soil depends naturally on the interaction among a series of biotic and abiotic factors, management practices often cause the deterioration of its physical, chemical and biological properties, and, thus, increase the levels of mineralization and a reduction in carbon stocks. This research was undertaken in the municipality of San José del Rincón, State of Mexico, in volcanic soils under different conditions of soil...

Rice growth and yield are adversely affected by soil salinity. The application of organic matter is a successful technique for saline soil remediation. The experiment was conducted to determine the effect of different organic materials on the response of rice in saline soil. Experimental design was a randomized complete block with 4 replicates comprised 4 treatments: 1) no organic material application (control) 2) sesbania application at the rate of 1,000 kg/rai 3) rice straw application at the rate of 1,000 kg/rai and 4) sesbania at the rate of 500 kg/rai and rice straw at the rate of 500 kg/rai. The result were shown that sesbania and rice straw treatment had the highest rice dry weight in all growth stages, the highest nutrient uptake at booting stage,...
