IBA and vitamin B1 combined together stimulate root development and encourage growth by 30 percent in most species of plants and 50 percent in hardwood plants and trees.
IBA has been in use for more than 70 years, but has almost exclusively been used with root cuttings and associated applications to enhance root regeneration.
IBA increases the rate of growth in young plants while simultaneously reducing the mortality rate in seedlings by up to 60 percent.
Crops retain between 30 and 70 percent of fertilizers applied, but it has been assumed that the remainder has been lost to leaching, denitrification, N2O gas emissions, runoff and erosion.
There are six primary nutrients that plants require. Plants get the first three—carbon, hydrogen and oxygen—from air and water. The other three are nitrogen, phosphorus and potassium.
To absorb phosphorus, most plants require a soil pH of 6.5 to 6.8.
Fertilizers enhance the growth of plants. This goal is met in two ways, the traditional one being additives that provide nutrients. The second mode by which some fertilizers act is to enhance the effectiveness of the soil by modifying its water retention and aeration.
Agricultural and chemical minerals are very important in industrial use of fertilizers, which is valued at approximately $200 billion.
Conservative estimates report 30 to 50 percent of crop yields are attributed to natural or synthetic commercial fertilizer.
