Multivariate Data Analysis Using R Software
ISBN: 9783848408139 / Angielski / Miękka / 120 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Multivariate analysis is branch of statistics designed to reduce the complexity of high dimensional data by creating a low- dimensional representation of the data without ignoring the relationships among individual taxa. R is an integrated suite of software facilities for data manipulation, calculation and graphical display. It is integrated collection of intermediate tools; graphical facilities and display either directly at the computer or on hardcopy make it vital. R is very much a vehicle for newly developing methods of interactive multivariate data analysis. It has developed rapidly, and...

Management of Salt Affected Soils
ISBN: 9783639356489 / Angielski / Miękka / 2011 / 96 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Salt-affected soils are common in arid and semiarid regions, where annual precipitation is insufficient to meet the evapotranspiration needs of plants. As a result salts are not leached from the soil. Instead they accumulate in amounts or types detrimental to plant growth. Salinity is the major and ever-present threat to the permanence of irrigation agriculture not only to arid or semiarid regions but also even in subhumid and humid regions. Unless salinity controlled, productivity decreases, land values drop and in severe cases the land is completely abandoned. This book entails detail...

Soil Science and Soil Fertility Management : Soil properties and plant Nutrient Management
ISBN: 9783639367591 / Angielski / Miękka / 2011 / 348 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. soil is the basis for life as it is the foothold for plants on which other lives are dependent. In any ecosystem, soils have five key roles. The knowledge about the soil should be comprehensive and supported with the practical management principles. This book enables to acquire all round knowledge on the introduction of Soil Science, functions and concepts of soil, soil forming factors and processes. Moreover, physical, chemical and biological properties of soils are briefly discussed in subsequent chapters. Emphasis is also given for essential plant nutrients and soil fertility management...

Natural Resources and Resource Scarcity in Ethiopia
ISBN: 9783846585474 / Angielski / Miękka / 2012 / 72 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Ethiopia is endowed with abundant natural resources and biodiversity. Yet the sustainability of these resources is under threat. The initial alarming projections of environmental scarcity, inadequate supplies of minerals to sustain industrialization and agricultural production are too limited to meet the needs of a growing population.Environmental services are inadequate to disperse increasing quantities of waste and have given way over time to a broader view of growing insecurity. Resource scarcity poses new challenges, it also encourages the development of technologies that allow for the...

Soil Acidity Effects on Land Productivity and Environment in Ethiopia
ISBN: 9783639351323 / Angielski / Miękka / 2011 / 64 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Soil Acidity affects soil ecology and plant growth. It influences soil productivity by elemental toxicity, reducing nutrient solubility and availability as well as microbial activity. Moreover, deficiency of elements (Ca, Mg, Mo), Phosphorous - fixation, incidence of plant disease (fungal) and poor bacterial growth are also observed. Activities such as mismanagement of agricultural practice, depletion of base cations, weathering of acidic parent material and organic matter dissociation boost soil acidification processes. However, the magnitude and rate of soil acidification...
