Producers have questioned the conventional advice to apply lime to change the pH of coastal soils. We look at one set of data on ryegrass pastures that shows the return on investment may indeed be modest.
The study showed that the crop performed equally well with and without gypsum and nutritional samples of the hemp flowers did not indicate any problems by discontinuing applications.
Drought has become a fact of life for farmers throughout the West. For hemp growers, careful planning for where, when and what to plant can result in a crop that will thrive despite dry conditions.
This fact sheet describes recent discrepancies between SMP and Sikora buffer pH lime requirement tests for western Oregon soils and provides recommendations for what to do. Many soil testing labs in the U.S. are switching from ...

Hemp plants are susceptible to disease, especially at the early stages of development. Hemp growers can promote healthy plants by using high-quality seed and avoiding soil that is wet, dense or poorly drained.
The plants in the field trials were chosen by an advisory group of nursery growers and landscape designers and were evaluated on growth, visual appeal, timing of flowering, density of flowers, physiology and heat tolerance.
