Advances in Research on Fertilization Management of Vegetable Crops
This book is a review of the recent literature on the key scientific and technical subjects of fertilization management in vegetable crops. In the last decades, research on fertilization management in vegetables was aimed at producing economical yields with reduced fertilizer inputs by the development and implementation of cropping systems, nutrient management approaches and crop varieties. Examples of the interventions in cropping systems included adequate crop rotations, inter-cropping, double cropping, and other strategies for a better soil organic matter management; nutrient management approaches included modelling, Decision Support Systems, crop nutritional status testing and precision agriculture technologies; amelioration of crop varieties has been directed toward higher nutrient/fertilizer use efficiency.
Umbria - Perugia, Orvieto, Spoleto and Assisi
Umbria, "the green heart of Italy," may not completely match Tuscany's geological variation, but it comes close. This small, hilly and fairly untouched region occupying Italy's core (Narni is the country's geographical center) is crammed full of walking, rafting, caving, hang-gliding and climbing opportunities, not to mention a rich artistic and architectural heritage left over the centuries by Etruscans, Umbrians, Romans and then by scholarly monks.Umbria has played a strategic role in Italy's busy history. Numerous archaeological finds have unearthed a human presence in Umbria dating back to Palaeolithic and Neolithic periods; flints and arrowheads have been found on several river plains a...
Weed Research
This book presents the most up-to-date and comprehensive guide to the current and potential future state of weed science and research. Weeds have a huge effect on the world by reducing crop yield and quality, delaying or interfering with harvesting, interfering with animal feeding (including poisoning), reducing animal health and preventing water flow. They are common across the world and cost billions of dollars’ worth of crop losses year on year, as well as billions of dollars in the annual expense of controlling them. An understanding of weeds is vital to their proper management and control, without which the reduction in crop yields that they would cause could lead to mass starvation a...
