Soil Fertility: QUEFTS and Farmers’ Perceptions

Soil fertility is one of many factors which influence farmers’ choices regarding agricultural production, fertilisation and soil and water conservation. Before we can study the effects however, we need to measure soil fertility. We use the QUEFTS model (QUantitative Evaluation of the Fertility of Tropical Soils Janssen et al., 1990), which predicts crop yields from chemical soil characteristics...

Conservation Agriculture Improves Soil Quality, Crop Yield, and Incomes of Smallholder Farmers in North Western Ghana

Conservation agriculture (CA) practices are being widely promoted in many areas in sub-Saharan Africa to recuperate degraded soils and improve ecosystem services. This study examined the effects of three tillage practices [conventional moldboard plowing (CT), hand hoeing (MT) and no-tillage (NT)], and three cropping systems (continuous maize, soybean-maize annual rotation, and soybean/maize int...

Bobik : Dig Deeply into Scientific Problems To Find Knowledge

A lthough the carboxysome was for nearly 30 years the only microcompartment recognized within microbial cells, additional microcompartments, including some that are involved in metabolic processes such as degrading carbon sources, are known. Cluster analysis of homologues of microbial microcompartment-specific proteins suggests that such enclosures could be involved in as many as seven differen...
