This publication provides direction on estimating soil moisture by the "feel and appearance" method; taking a some soil and rolling it up in a ball then squeezing it between your thumb and forefinger to form a ribbon and noting how it appears and feels. Compare what you see with photographs and/or charts to estimate percent water available and the inches depleted below field capacity.
Independent of which system or mix of systems a grower uses, irrigation management can be challenging. An irrigation program must match the changing demands of the crop with the water supplied.
Stormwater runoff from impervious surfaces has been routed directly to streams through stormwater pipes and ditches with little infiltration or treatment.
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.
Gardeners in the Willamette Valley can successfully grow succulent plants by creating conditions that allow them to thrive. That includes well-drained soil and proper watering. Here's a guide.
Collection of forage resources, mostly for Coastal Oregon regions. Includes studies on fiber digestibility, phosphoric soil, rations, and cost/benefit of growing and buying locally grown forages.
Cool-season perennial and annual forages often struggle during the heat of summer. Fortunately, there are some strategies to consider — including planting drought-tolerant forages, warm-season grasses and annual legumes.
When a heatwave hits, plants may show the impact. Learn the signs of heat stress in plants and how to help them weather a heatwave with best practices for watering, mulching, shading, providing humidity and weeding.
