Soil fertility capability classification (FCC) for rice production in Cameroon lowlands

Comparision of fertility capability and taxonomic classification systems to classify the soil map units in some parts of Chaharmahal-va-Bakhtiari province

Although fertility capability classification (FCC) has high performance in land evaluation and soil maps interpretation, so far it has been less attended in land evaluation studies. Therefore, qualitative (FCC method) and quantitative (Riquer index) land fertility capability evaluation for Wheat and Rice cultivation and comparison of Soil Taxonomy and WRB classification with FCC were chosen as ...

Soil Fertility and Bean Production

Beans require adequate amounts of all essential plant nutrients for optimum growth but only a few nutrients are documented to be needed for southern Idaho soils. These nutrients include phosphorus (P), nitrogen (N), zinc (Zn), potassium (K), sulfur (S), and to a much less extent B, Cu, Mn and Fe. University of Idaho Agricultural Experiment Station research as well as research from throughout th...

Soil fertility in flooded and non-flooded irrigated rice systems

Soil Fertility Map for Food Legumes Production Areas in China

Given the limited resources of fossil energy, and the environmental risks of excess fertilizer on crops, it is time to reappraise the potential role of food legume biological nitrogen fixation (BNF) as sources of nitrogen for cropping systems in China. 150 soil samples across 17 provinces and 2 municipalities of China were collected and analyzed. A distribution map of the soil fertilities and t...

Gibberellic Acid: A Key Phytohormone for Spikelet Fertility in Rice Grain Production

The phytohormone gibberellic acid (GA) has essential signaling functions in multiple processes during plant development. In the "Green Revolution", breeders developed high-yield rice cultivars that exhibited both semi-dwarfism and altered GA responses, thus improving grain production. Most studies of GA have concentrated on germination and cell elongation, but GA also has a pivotal role in flor...
