Soil quality (SQ) assessment is a proactive process for evaluating soil and crop management effects on biological, chemical, and physical indicators of soil health. Our objectives were to evaluate several SQ indicators within five Agricultural Research Service (ARS) experimental watersheds (WS) and determine if those indicators were affected by manure, tillage, or crop rotation histories. Ten s...

soil quality is the most suitable index to an assessment of the stability of terrestrial ecosystems, especially agro-ecosystems. to determine the effects of agricultural practices on soil organic matter, species richness and abundance of soil invertebrates, a study was conducted in three regions of razavi and northern khorasan provinces, iran. soil were taken from in each winter wheat field of ...

To investigate better saline water irrigation scheme for tomatoes that scheduling with the compromise among yield (Yt), quality, irrigation water use efficiency (IWUE) and soil salt residual, an experiment with three irrigation quotas and three salinities of irrigation water was conducted under straw mulching in northern China. The irrigation quota levels were 280 mm (W1), 320 mm (W2) and 360 m...

The aim of this study was to develop a systematic quality index for application in the cultivation of Agaricus bisporus (Lange) Imbach mushrooms, based on the physical, chemical and biological properties (indicators) of the compost and casing layers (factors). The relative importance (weight) of each of the factors and indicators, their normalized scores, the quality index values and the correl...

In order to support interoperability of learning tools and reusability of resources, this paper introduces a framework for harvesting learning objects from web-based content. Therefore, commonly-known web technologies are examined with respect to their suitability for harvesting embedded meta-data. Then, a lightweight application profile and a microformat for learning objects are proposed based...

The changes induced by illumination variation are larger than the differences between individuals. This difference escalates the misclassification rate and thus aggravates the performance. So to improve the performance, illumination normalization/compensation becomes an essential preprocessing step. In this paper we propose a method Region Based Self Quotient Image (RBSQI) for illumination comp...

Physical properties of soil are good for plant growth is closely related to the management soil, so it will need integrate physical get an overall assessment with making quality index (SPQI). This study aims evaluation and determines using several unit treatments produce various qualities on Groundnut/Arachis hypogeal L. The location research was carried out in a farmer's garden Cimaung Village...
