Crop and Soil Responses to Using Corn Stover as a Bioenergy Feedstock: Observations from the Northern US Corn Belt

Johnson, Jane M. F.; Acosta-Martinez, Veronica; … - In: Agriculture 3 (2013) 1, pp. 72-89

Corn (Zea mays L.) stover is a potential bioenergy feedstock, but little is known about the impacts of reducing stover return on yield and soil quality in the Northern US Corn Belt. Our study objectives were to measure the impact of three stover return rates (Full (~7.8 Mg ha−1 yr−1),...

Earthworm Populations in Savannas of the Orinoco Basin. A Review of Studies in Long-Term Agricultural-Managed and Protected Ecosystems

López-Hernández, Danilo - In: Agriculture 2 (2012) 2, pp. 87-108

Earthworm biomass and production in savannas are limited by seasonal precipitation and the lack of organic and nutrient resources; I hypothesize that after a long-term protection of savanna from fire and agricultural activities drastic changes in the physical and chemical characteristics of the...

Soil Microbial Activity in Conventional and Organic Agricultural Systems

Araújo, Ademir S.F.; Leite, Luiz F.C.; Santos, Valdinar B. - In: Sustainability 1 (2009) 2, pp. 268-276

The aim of this study was to evaluate microbial activity in soils under conventional and organic agricultural system management regimes. Soil samples were collected from plots under conventional management (CNV), organic management (ORG) and native vegetation (AVN). Soil microbial activity and...

Agricultural Systems Located in the Forest-Savanna Ecotone of the Venezuelan Amazonian. Are Organic Agroforestry Farms Sustainable?

López-Hernández, Danilo; Hernández, Carmen Leonor; … - In: Sustainability 1 (2009) 2, pp. 215-233

The savannas located in the forest-savanna ecotone in the Venezuelan Amazon have unfertile sandy ultisols and entisols which show a very low crop production unless they are supplemented with large amounts of fertiliser. In spite of this restriction, local farmers have established long-term...

Effects of drought stress on agriculture soil

Geng, S.; Yan, D.; Zhang, T.; Weng, B.; Zhang, Z.; Qin, T. - In: Natural Hazards 75 (2015) 2, pp. 1997-2011

experiments were designed in this study. The objective of this study was to identify changing tendencies of microbial biomass … carbon content and the proportion of microbial biomass carbon in soil organic carbon under different drought conditions. All … content of microbial biomass carbon was selected as indicator for identifying effects of extreme drought on agriculture soil …
