PRESENTATIONCollection "Agricultural sciences unveiled: exploring the dynamics of farming and sustainability": a work that has as its main focus a scientific discussion through various works that compose its chapters. The purpose of the Ebook is to explore different contents linked to environmental issues in 19 chapters, tracing a contemporary theme of sustainability and the direct action of human beings in the responsibility and creation of strategies for the development of the environment. The volume will address in a categorized and interdisciplinary way works, investigations, case reports and/or reviews that go through the various areas of the environment and sustainability.It is worth mentioning that sustainability is tied to the growing demand for global progress, with the emergence of the need to expand studies that present alternative uses of the present resources in the environment in a responsible manner, without compromising the benefits and systems involved. Seeking to minimize impacts, develop environmental responsibility and strengthen sustainable growth. Thinking about development allied to sustainability involves economic, social, and cultural aspects.In this way, the work "Agricultural sciences unveiled: exploring the dynamics of farming and sustainability"" presents the foundation of the theory obtained in practice by the authors of this e-book, several professors, academics, and researchers who have arduously developed their work that will be presented here in a manner concise and didactic. The importance of this space for scientific dissemination is evidence or commitment and the structure of Atena Editors that provides us with a consolidated and trustworthy platform for researchers to expose and disseminate their results.The authors hope to contribute with relevant content to provide technical, scientific, and constructive ass...

Fertilization is a critical input factor in crop production and food security achievement. However, there is room for improvement in the application of fertilizers in certain regions. Thus, using low-cost fertilizers, such as phosphogypsum (PG), could enhance farmers' access to these essential inputs. A two-years field experiment was conducted using two Moroccan PG products applied at four rates (0, 1.5, 3, and 4.5 t/ha). The aim was to assess the impact of PG source and rate on barley crop, including yield component, nutrients uptake, and heavy metals content. The study's findings revealed that as the rate of PG application increased, there were significant enhancements in the number of spikes, tillers, grains, total biomass, grain yield, and thousand grains weight. In fact, when compared to the control, the application of 1.5, 3, and 4.5 t/ha of PG led to a remarkable increase in grain yield by 21%, 34%, and 39%, respectively. Furthermore, the uptake of nutrients by the shoots and grains was significantly influenced by the PG application rates, with higher rates resulting in greater nutrient uptake. Notably, the application of PG had no impact on the heavy metal content in shoots, grains, or soil.

“…The annual production of PG worldwide is estimated to be 200 million tons (Chernysh et al, 2021). However, only 15% is recycled on a global scale including construction, agriculture and others (Outbakat et al, 2023). Because of PG's acidic nature (pH < 3, as opposed to natural gypsum being a natural salt (Outbakat et al, 2023)), high sulphur content and high solubility, we hypothesized that it could be an alternative additive to improve the solubility of PR.…”

The direct application of phosphate rock (PR) has been found suitable for acidic soils. Still, efforts are needed to improve its reactivity to match grassland P demand. This research aimed to investigate changes in the dissolution of two Moroccan sedimentary PRs (Ben Guerir and Khouribga) in response to four rates of phosphogypsum (PG)—a by-product of the phosphate fertilizer industry. We conducted a 60-day incubation study using two acid soils from New Zealand. The soils were treated with PRs at 100 mgP kg−1 of soil either alone or combined with PG, which was applied at 0, 1, 3 and 9 t ha−1 (approximately the equivalent of 0, 0.9, 2.7, and 8.1 g of PG kg−1 of soil, respectively). The dissolution rates were determined from the differences in residual calcium (Ca) extracted with 1 M HCl. Soil pH, Olsen P, exchangeable aluminium (Al) and Ca and Ca saturation were analyzed at the end of the experiment. Phosphate rocks and PG’s physicochemical properties were characterized. Phosphogypsum addition increased Olsen P by 34% and 59% at 9 t ha−1 compared to 0 t ha−1 in Molesworth and Lindis Peaks soils, respectively. However, PG did not affect the dissolution of PRs in the different of soil types. Khouribga PR was more reactive than Ben Guerir PR, especially in the Molesworth soil where soil pH and base saturation were lower and P retention was higher compared to Lindis Peaks soil. Particle size distribution was the key factor that contributed to the observed greater reactivity of the Khouribga PR. Both PRs showed dissolution rates >50%, suggesting their suitability for direct application on acid soils. Being an important source of sulphur and some P, PG if combined with PR, can promote and complement PR’s direct use as fertilizer on acid soils. Moreover, the development of new fertilizer products by combining these two materials should be encouraged.
