Multi-Location Study of Soil Enzyme Activities as Affected by Types and Rates of Manure Application and Tillage Practices

Acosta-Martinez, Veronica; Mikha, Maysoon M.; Sistani, … - In: Agriculture 1 (2011) 1, pp. 4-21

Significant amounts of manure are produced in the USA; however, information on the changes in ecosystem services related to soil biogeochemical cycling for agroecosystems supported with organic amendments such as manure is limited. A multi-location field study was initiated in Colorado (CO),...

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...

The Potential Impact of Climate Change on Soil Properties and Processes and Corresponding Influence on Food Security

Brevik, Eric C. - In: Agriculture 3 (2013) 3, pp. 398-417

According to the IPCC, global temperatures are expected to increase between 1.1 and 6.4 °C during the 21st century and precipitation patterns will be altered. Soils are intricately linked to the atmospheric/climate system through the carbon, nitrogen, and hydrologic cycles. Because of this,...

Crop and Tillage Effects on Water Productivity of Dryland Agriculture in Argentina

Noellemeyer, Elke; Fernández, Romina; Quiroga, Alberto - In: Agriculture 3 (2013) 1, pp. 1-11

Rising demands for food and uncertainties about climate change call for a paradigm shift in water management with a stronger focus on rainfed agriculture. The objective here was to estimate water productivity of different crops under no-till (NT) and conventional till (CT), in order to identify...

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),...

Pyrolysis Kinetics of Physical Components of Wood and Wood-Polymers Using Isoconversion Method

Jin, Wenjia; Singh, Kaushlendra; Zondlo, John - In: Agriculture 3 (2013) 1, pp. 12-32

Two hardwood species, namely red oak and yellow-poplar, were separated into their bark, sapwood and heartwood components. The samples were tested for calorific value, specific gravity, proximate analysis, mineral composition, chemical composition, ultimate analysis, and thermo-chemical...

Differentiation of Blossom Honey and Honeydew Honey from Northwest Spain

Olga, Escuredo; María, Fernández-González; Carmen, … - In: Agriculture 2 (2012) 1, pp. 25-37

The knowledge of important parameters for honey characterization is an increasing requirement of consumers and the honey industry. In this respect, differentiation between blossom honeys and some honeydew honeys is still an unresolved task. This study includes the results of physicochemical and...

Managing Soil Erosion in Northern Ireland: A Review of Past and Present Approaches

Mullan, Donal - In: Agriculture 3 (2013) 4, pp. 684-699

In recent decades, the off-site transport of sediment and nutrients from agricultural land into the neighbouring natural and built environment has become a more pressing environmental sustainability issue than the on-site threats of soil erosion in many of the world’s temperate regions. In the...

Functional Food and Organic Food are Competing Rather than Supporting Concepts in Europe

Kahl, Johannes; Załęcka, Aneta; Ploeger, Angelika; … - In: Agriculture 2 (2012) 4, pp. 316-324

A review of recent literature pertaining to organic and functional food was conducted according its conceptual background. Functional and organic food both belong to fast growing segments of the European food market. Both are food according to the European food regulations, but organic food is...
