The use of bio-stimulants in agriculture has emerged as a promising strategy to improve crop growth and yield. One type of bio-stimulant that has gained attention is microalgae extracts, which are known for their high metabolic activity, bioactive compounds, and ability to enhance plant growth a...
(1:1, v/v). The mixture was heated on a hot plate until the digest became clear. After the digestion process, the mixture was cooled, filtered, and completed to 25 mL with twice-de-ionized H2O. The phosphorus, potassium, magnesium, and calcium concentrations were determined and expressed ...

By this method the underside of the root pass remains clean and sound so that little grinding is needed before depositing the next bead from the opposite side of the joint. Top Out of Position Welding [fromPWL#039, Section 3] Q: What makes an all position welding rod/wire,'all position...
15. Why to block slag out of steel? One of the necessary means to produce pure steel is to reduce slag or block slag out of steel. The purpose is to accurately control the composition of molten steel, effectively reduce the phosphorus return of molten steel, improve the absorption rate of...
Nutrient deficiency alters growth and the production of high-quality nutritious food. In Citrus crops, rootstock technologies have become a key tool for enhancing tolerance to abiotic stress. The use of doubled diploid rootstocks can improve adaptation t
