abstract nowadays, fuzzy technique is used to prepare the map in different sciences, extensively. with due attention to important role of soil fertility in modern agriculture, the preparation of soil fertility map seems to be necessary to plan for appropriate using of fertilizers for crops. this study was conducted to prepare a distinct map for evaluating soil fertility according to soil availa...

Understanding the effects of external organic and inorganic components on soil fertility and quality is essential for improving low-yielding soils. We conducted a field study over two consecutive rice growing seasons to investigate the effect of applying chemical fertilizer (NPK), NPK plus green manure (NPKG), NPK plus pig manure (NPKM), and NPK plus straw (NPKS) on the soil nutrient status, en...

Soil fertility is a comprehensive reflection of soil properties, and its variation has been a central issue in the field of soil science. Most of current research on Variation of the soil fertility are most for a single time and place, and using expertise, simple mathematical model approach that can not effectively simulate the temporal and spatial variation of soil nutrients law. Therefore, th...

Maize is a staple summer crop grown in the hilly areas of Nepal, where the soil is fragile and fertility is declining over years due primarily to degradation of natural resource base, high rates of soil erosion, increased cropping intensity and inadequate replenishment of soil nutrients. Forum for Rural Welfare and Agricultural Reform for Development (FORWARD) with the financial support from Hi...

Soil fertility evaluation and management can be greatly improved with the use of precision agriculture technologies. Differential global positioning systems (DGPS), yield monitors, various forms of remote sensing, geographical information system (GIS) computer software, and variable rate technologies are available for use to producers. Intensive soil sampling, crop scouting, and other practices...

Throughout the world there is a strong evidence to support the link between poverty and soil conditions. In subsistence agriculture the wealth of people on low fertility sandy soils is much lower than those living on rich volcanic soils. But there are great differences between regions in the world and this talk focuses on historical developments in soil research in tropical and temperate region...

Appropriate fertilizer application is an important management practice to improve soil fertility and quality in the red soil regions of China. In the present study, we examined the effects of five fertilization treatments [these were: no fertilizer (CK), rice straw return (SR), chemical fertilizer (NPK), organic manure (OM) and green manure (GM)] on soil pH, soil organic carbon (SOC), total nit...

General knowledge of the small, invisible, or hidden organisms that make soil one of the most biodiverse habitats on Earth is thought to be scarce, despite their importance in food systems and agricultural production. We provide the first worldwide review of high-quality research that reports on farmers’ knowledge of soil organisms in agriculture. The depth of farmers’ knowledge varied; some fa...
