Background and aims Rhizosheath, the soil attached to plant roots, may enhance drought resilience by improving water and nutrient uptake. This study evaluates the effects of rhizosheath formation on water and nutrient absorption from soils with different textures and moistures. Methods Two maize inbred lines R109B (Rh +) and Ky228 (Rh-), known for...

The book “Methods of Soil Analysis; Sampling, Chemical and Physical Methods” is a comprehensive textbook with a focus on the characterization of soils in arid and semi-arid regions and consists of 31 chapters that cover most of the methods of soil analysis. The current book is intended to provide a standardized and coordinated reference for soil an...

In the process of conducting this research, 110 studies on monitoring nitrate content in agricultural products produced in Iran were gathered. These studies were published until March 20, 2023. The collected studies underwent evaluation for methodology, quality control, and quality assurance of results and were then assessed based on standard resea...

Background and aims Rhizosheath, a mixture of soil and mucilage that remains attached to the root system after being removed from the soil and shaken, plays a prominent role in the resistance of plants to drought stress. This study aims to investigate the effect of silicon (Si) on rhizosheath formation and mitigate the effects of drought stress in...

The main challenge of the twenty-first century is to find a balance between environmental sustainability and crop productivity in a world with a rapidly growing population. Soil health is the backbone of a resilient environment and stable food production systems. In recent years, the use of biochar to bind nutrients, sorption of pollutants, and inc...

Background and Aims The optimal management of plant nutrition is an effective strategy for sustainable agriculture under various conditions. Soil drying is one of the main limiting factors for plant nutrient acquisition. Plants imposed to these limitations have evolved several strategies such as modifying root-to-shoot ratio, modifying their root a...

Abiotic stresses such as salinity and drought stresses are known as the main constraints for optimum growth of plants, especially in arid and semi-arid regions. Therefore, in recent years, agricultural scientists have begun to research about the fertilizers that have a multifaceted use and can be used to maintain the optimum growth and yield of str...

Background and Objective: Land degradation is one of the destructive phenomena that threaten the stability and security of ecosystems, especially in arid areas. Land degradation can lead to reduced soil fertility and productivity, population migration and displacement, food insecurity, and ecosystem destruction. Despite widespread efforts to combat...

Potassium, as an essential element, which its role in plant metabolism and resistance to biological and environmental stresses has been proven many times, requires accurate extraction and measurement for optimal management. The present study was conducted to investigate the effect of soil/extractant ratio on measuring the amount of available potass...

Optimal plant nutrition is one of the accurate solutions to meet the demands of population growth and food in the future. In order to study the effect of different fertilizers on the responses of tomato plant, a greenhouse experiment was conducted as a factorial arrangement based on a completely randomized design with three replications. The applie...

Soil pollution by potentially toxic elements (PTEs) as one of the major environmental hazards is associated with metal exploration and refining acting. In this study, forty-five topsoil samples surrounding a copper smelter factory were taken and analysed using standard routine methods. The total concentration, chemical fractionation and the mobilit...

Sustainable agriculture has been consistently challenged due to the menace of changing climate, thereby, causing depletion in carrying capacity of soil vis-à-vis agronomic response of crop. Of late, biochar has turned out to be the most promising option to address these issues. The present review takes stock of the research work accrued under varie...

The present study was carried out to investigate the effects of biological and chemical fertilizers on morpho-physiological characteristics and nutrients uptake in tomato plant (Lycopersicon esculentum Mill). A factorial trial arranged in a completely randomized design was carried out under greenhouse conditions. Treatments consisted of five levels...
