Ebook "Phytoremediation and biofortification: Two sides of one coin" is a valuable resource to students, technicians, and academics who are interested in the treatment of environmental problems (bioremediation) through the use of plants, and in the field of biofortification. This book shows how, despite having different goals, both phytoremediation and biofortification technologies can be closely connected as they are both based on the phytoextraction process that involves plant uptake, accumulation, and transformation of nutrient elements from soil.

Ebook "Nutrient use efficiency in plants: Concepts and approaches" presents a broad overview of topics related to improvement of nutrient use efficiency of crops. Nutrient use efficiency (NUE) is a measure of how well plants use the available mineral nutrients. It can be defined as yield (biomass) per unit input (fertilizer, nutrient content). NUE is a complex trait: it depends on the ability to take up the nutrients from the soil, but also on transport, storage, mobilization, usage within the plant, and even on the environment.

Ebook "Principles of terrestrial ecosystem ecology (Second edition)" regards living organisms, including people, and the elements of their environment as components of a single integrated system. The comprehensive coverage in this textbook examines the central processes at work in terrestrial ecosystems, including their freshwater components. It traces the flow of energy, water, carbon, and nutrients from their abiotic origins to their cycles through plants, animals, and decomposer organisms.

In ebook "Ecology of cyanobacteria II: Their diversity in space and time" cyanobacteria have existed for 3.5 billion years, yet they are still the most important photosynthetic organisms on the planet for cycling carbon and nitrogen. The ecosystems where they have key roles range from the warmer oceans to many Antarctic sites. They also include dense nuisance growths in nutrient-rich lakes and nitrogen-fixers which aid the fertility of rice-fields and many soils, especially the biological soil crusts of arid regions.

Runoff reduction is the goal of soil and water conservation in agricultural watersheds. Through the runoff, many substances of soil such as sediment, nutrients have been eroded to end up in streams, rivers, and lakes. In decades, studies have revealed various mitigation, including structure and non–structure conservation ranging from field scale to watershed scale.

Root is the prime organ that sucks water and nutrients from deep layer of soil. Wild barley diversity exhibits remarkable variation in root system architecture that seems crucial in its adaptation to abiotic stresses like drought. In the present study, we performed quantitative trait locus (QTL) mapping of root and related shoot traits under control and drought conditions using a population of wild barley introgression lines (ILs).

Coastal dunes are characterised by plant species adapted to harsh conditions. Salinity and other factors (soil pH, nutrients, and climate events) vary along the landward gradient. The current study investigated the effects of environmental factors on the occurrence and composition of coastal dune plants. Ellenberg ecological indicator values (EIVs), species tolerance values (TVs), and species niche models for salinity, nutrient availability, and soil reaction were determined.

In paper "Fine root vertical-seasonal distribution of Robinia pseudoacacia in relation to abiotic factors in a chronosequence in coastal saline alkali land of the Yellow River Delta, China", FRB, FRL, FRSA, SWC and soil nutrients increased, while SRL and SSC decreased with increasing stand age. Vertically, fine roots were concentrated in a 0–20 cm soil layer. SRL, SWC and SSC increased, while soil nutrients decreased with increasing soil depth.

The study "Biochar mitigates salt stress by regulating nutrient uptake and antioxidant activity, alleviating the oxidative stress and abscisic acid content in cabbage seedlings" was conducted as factorial completely randomized design with two factors; salinity levels (0 and 150 mM NaCl) and biochar doses (weighed at the rate of 0%, 2.5%, and 5% by soil weight). Growth parameters such as stem diameter, leaf area, shoot fresh weight, root fresh weight, shoot dry weight, and root dry weight of cabbage seedlings treated with 150 mM NaCl were lower than the control.

Nitrogen (N) and phosphorus (P) are essential nutrients for plant growth and development. However, too much N and P can be toxic to plants and hurt crops and animals. Analysis and assessment of N and P content in soil and crops will help build a balanced and effective fertilizer plan for agricultural production. This study introduces a new method to determine both TP and TN in one process, reducing the analytical cost and time.

Enhanced efficiency fertilizers (EEF) are an important subject for sustainable materials. It is fundamental for the released nutrient and biodegradation in the soil to have synergy to ensure material harmlessness. Chitosan, montmorillonite, and KNO3 were considered to develop the EEF because of the high biodegradation potential of the final product.

Different types of land use, practices and management can alter biogeochemical cycling of a piece of land by the effect it produces on soil properties. The conversion of forest land to agricultural land and wastelands to forest land use have been in practice from primordial days due to land hunger and reclamation.
