Foliar fertilizers and biostimulants are vital tools in modern agriculture. Foliar fertilizers are nutrient solutions applied directly to leaves, enabling rapid absorption through the cuticles and stomata. They provide a quick nutrient boost to plants. Biostimulants, including various substances and microorganisms, enhance natural processes, improve nutrient uptake, and increase resilience to environmental stresses like drought and extreme temperatures. By promoting overall plant growth and development, these products help maximize crop yields and plant health. Together, foliar fertilizers and biostimulants offer an integrated approach to optimizing agricultural productivity.
