Irrigation Water Guidelines - Noble
crops, use of water with an appreciable liming potential is not of concern and may lower the need for agricultural lime additions. However, some crops such as pecans can be adversely affected as increasing the pH will make micronutrients such as zinc less available. Boron – an anion element that is usually not a problem in most crops. High ...
