Biological fertilizers are compounds comprising various free living microorganisms that are able to change the basic nutrients into available form through biological procedures. Being an important source of nutrients in sustainable agriculture, these fertilizers lead to better seed germination and development of root system. In order to investigate the effect of biological fertilizers on the me...
Abstract During the growing season, a field experiment was conducted in one of fields Um Al-Akf region (about 5 kilometers from heart Al-Muthanna Governorate) at 45.23 longitudes and 31.32 latitudes (2021-2022). Three cultivars were produced for first time governorate, they compared to approved variety Ibaa 99, determine impact spraying micro-Nano fertilizers different stages had on growth char...
The composting industry has been growing rapidly in China because of a boom in the animal industry. Therefore, a rapid and accurate assessment of the quality of commercial organic fertilizers is of the utmost importance. In this study, a novel technique that combines near infrared (NIR) spectroscopy with partial least squares (PLS) analysis is developed for rapidly and accurately assessing comm...
The activity concentration of naturally occurring radionuclides K, Ra and Th have been measured in different brands of fertilizer samples in Saudi Arabia using sodium iodide gamma spectrometry. The results of measurements showed that the mean (ranges) of specific activities for Ra, Th and K activities in the nitrogen, phosphorus and potassium fertilizers are 64 (35.8 120.7), 17 (3.2 56.8) and 2...
Application of polymer-coated controlled-release fertilizers (CRF) during outplanting has resulted in variable growth responses in the Pacific Northwest (PNW). Results have been linked to several factors, including soil moisture availability. Multiple experiments were designed to examine the influence of CRF on Douglas-fir seedling root architectural development and establishment. Placement of ...
Drought stress is one of the abiotic factors that reduces crop production. The use of biofertilizers can mitigate the negative effects of drought stress and reduce chemical inputs on agricultural systems. In order to investigate the effect of combined management of chemical and biological fertilizers on yield and quality-related traits of black cumin (Nigella sativa L.) under different irrigati...
