“…The three organisations have jointly developed a mapping instrument for the current coverage of areas, as well as for the field degradation types and tendencies [37]. As such, a variety of feedback mechanisms have resulted that involve processes such as: a) changing soil properties and field degradation [2,5,29]; b) combining vegetation and climate; c) changes in the composition of plant species.…”

Even from the middle of the 19th century desertification was considered a controlled artificial process with anthropic factors as the main cause. Forest treatments applied in tropical forests in an incorrect manner have led to soil degradations and a destabilization of climatic and hydrologic regimes. In these conditions, desertification and its indicators have regressed in regard with agricultural and forestry productivity. This was caused by a non-sustainable management characterised by exploitation anthropic activities realized in an uncontrolled procedure. In 1994, the desertification definition was updated by introducing climatic factors and abusive grazing as consequences of field degradation. The main purpose of this article is to understand the concept of” desertification” and to elaborate a qualitative analysis based on published scientific articles in order to investigate the influence factors that led to the apparition of this phenomenon in Europe, Asia, Latin America and Africa. The scientific objectives consist in analysing the evolution of desertification in different affected regions as well as to analyse the influence factors that led to the ecological destabilization of agricultural and forestry domains through degradation and a reduction of silvo-biologic productivity. The results were based on analysing 74 articles published in specialty agricultural and forestry journals or magazines by institutions or associations of owners, managers of waters and forests, forestry specialists, academicians and ecologists. They have all studied the present problem posed by desertification as well as modern applied methods for rehabilitating ecologic conditions in degraded ecosystems from semi-arid, arid and extremely arid areas.

“…One of these is to evaluate the activity of soil microorganisms based on specific indicators, for example, dehydrogenase activity (Samuel et al, 2021). Dehydrogenase activity produced by the soil microbiota represents an efficient indicator for soil health status (Bireescu et al, 2010).…”

“…Dehydrogenase is an intracellular enzyme and provides information only about the biologically viable, active microbial cells in the soil. For this reason, dehydrogenase activity is considered an indicator of the microbiological REDOX system and an efficient indicator of the soil health (Bireescu et al, 2010;Furtak and Gajda, 2017;Bireescu et al, 2018;Małachowska-Jutsz and Matyja, 2019).…”

Currently there is a growing interest both in obtaining large agricultural yields in order to provide food for a growing population as well as in increasing the sustainability of production systems by improving the health of the soil. The overall objective of this study was to evaluate the effect of organic versus chemical fertilization versus irrigation on runner bean crop and soil health. A bi-factorial field experiment was organized in a split plot design with three replicates during two years (2019 and 2020). The first factor, irrigation, had two graduations: irrigated with 3000 m 3 ·ha-1 (Ir) and non-irrigated (Non-Ir). The second factor, fertilization, had four graduations: biosolids (1200 kg·ha-1 ) (B), chemical (360 kg·ha-1 ) (Ch), microorganism (80 kg·ha-1 ) (M) and unfertilized (Unfert). The results showed that, regarding the physiological state of the plants, both the photosynthesis and the chlorophyll content were higher at Ir x M (5.31 µmol CO2 m -2 s -2 and 45.23 SPAD units, respectively). The yield of dried beans ranged between 1476-4811 kg·ha-1 in 2019 and 1498-4727 kg·ha-1 in 2020 and was highest for Ir x Ch. Soil health status estimated by determining the dehydrogenase activity in the soil, has been improved for irrigated (Ir) and fertilized (B, M, Ch) variants.
