Soil health in orchards
No full textOrchard soil health, or soil quality, is the capacity of soil to support productive trees over time without negatively affecting the surrounding environment. Soil health is influenced by interacting biological, physical, and chemical properties of soil. Active soil biological communities mineralize nitrogen, create soil structure, and compete with plant pathogens. Physical properties of soil determine its ability to store and release nutrients; accommodate water entry, storage and movement; provide sufficient oxygen for roots and microbes; and moderate environmental stress. Chemical aspects of soil health include nutrient presence and availability, pH, cation exchange capacity (CEC), salinity, and the presence of any contaminants, such as heavy metals or persistent pesticide residues. By increasing our understanding of the biological and physical as well as chemical properties of soil we may be able to increase root health, moderate nutrient and water stress, and increase the yield potential of our orchards
Foliage Canopy of Apple Trees in Formal Architecture
No full textAuthor: XIN ZHANG (questions of how to use this branch, please contact [email protected] or please refer to Xin Zhang's PhD dissertation at WSU).
This is a set of image/label (MATLAB-based gTruth) data of foliage canopy of apple trees in formal architecture. Images/labels could be used for (semantic segmentation-based) deep learning for objects indentification (e.g., trunks, branches, apples, etc.) Images were acquired in 2018 apple harvesting season near Prosser, WA (USA) using Kinect V2 sensor (with background removed). The apple cultivars include: Fuji (674 images), Envy (58 images), Scifresh (38 images), and Pink Lady (15 images)
2019 cost estimates of producing fresh and processing potatoes in Washington
No full textThe results presented in this WSU publication serve as a general guide for evaluating the feasibility of producing potatoes in the Columbia Basin as of 2019, with a capital and machinery endowment suited to a 1,000-acre potato enterprise. This publication is not intended to be a definitive guide to production practices, but is helpful in estimating the physical and financial requirements of comparable plantings. Costs can also be calculated differently depending on the intended use of the budget. To avoid unwarranted conclusions for any particular farm, readers must closely examine the assumptions made in this study, and then adjust the costs and returns as appropriate for their operation
Best management practices for managing herbicide resistance
No full textHerbicide resistance is a problem that has quickly spread throughout the wheat growing regions of the inland Pacific Northwest. Overreliance on herbicides for the management of weeds is a major cause of herbicide resistance. Integrated weed management relies on a wide range of practices to manage weeds and slow the development and spread of herbicide resistance. This publication presents growers and farm managers with best management practices (BMPs) that can be incorporated into farming systems to manage herbicide resistance
