Salix Production for the Floral Industry in the USA Who Grow Willows
Salix production for the floral industry in the USA Who grow willows • Plant nurseries (ornamental and erosion control) • Biomass growers • Basket makers • Floral cut-stem production The USDA Specialty Crop Initiative • the production of woody ornamental cut stems, representing a specialty niche in cut flower production, has risen in popularity • dogwood (Cornus), Forsythia, Hydrangea, lilac (Syringa), and Viburnum • potential as an off-season production option, or third crop enterprise Objectives • to characterize the extent of Salix cultivation as a floral crop in the USA by identifying the active willow growers and their profiles, production acreage and gross sales • to identify if the production practices are well defined and consistent to support crop expansion • the potential the crop’s expansion Distribution and concentration of Salix survey recipients in the United States 52 growers The Association of Specialty Cut Flower Growers (ASCFG) Grower profile • Small scale specialty cut flower producers (58.6%) • Large scale specialty cut flower producers (24.1%) • 24.1% considered Salix as “major crop” –Total gross sales for 80.0% was less than $25,000; 17.0% grossed $25,000- 50,000 and 3% grossed $50,000- 100,000 • good cash return, up to $1.25 to $1.75 per stem of common pussy willow • annual gross financial returns for willow plants, up to $24.94, is much higher than for many other woody florals Taxa in cultivation • For catkins •For Stems The seasonality of the crop Willow harvest for ornamental value by number of growers reporting -
23 a CROP ROTATION PLANNING PROCEDURE Note
23 A CROP ROTATION PLANNING PROCEDURE Note: this chapter is modified from Chapter 5 of Crop Rotation on Organic Farms: a Planning Manual by Charles L. Mohler and Sue Ellen Johnson, NRAES Press. It is intended to be used in conjunction with that manual, not as a substitute for it. General instructions This chapter provides a step –by-step procedure for planning crop rotations on an individual farm. The procedure is based on methods used by the panel of expert farmers discussed in Chapter 2 supplemented with other sources. The procedure distills what experienced growers do based on experience, knowledge and intuition into a systematic method. For the sake of simplicity, the instructions are written as if the person doing the planning is the manager of the farm. The crop rotation planning procedure works through a series of steps. You will (i) organize your information, (ii) develop a general rotation plan (optional), (iii) construct a crop rotation planning map, (iv) plan future crop sequences for each section of the farm, and (v) refine your crop sequence plan. The procedure is easiest for a farm that produces only a few crops and has uniform field conditions. Examples include cash grain farms and some wholesale vegetable operations where all of the crops can be grown on all of the fields. The procedure can be used to plan rotations with more crops and multiple soil types, but the process is time consuming. The rewards of systematic crop rotation planning increase, however, with the number of crops and complexity of the fields. On farms that grow only a few crops, reasonable rotations can be maintained using a few rules of thumb. -

SQL08 – Intercropping to Improve Soil Quality and Increase Biodiversity
United States Department of Agriculture Natural Resources Conservation Service 2012 Ranking Period 1 Soil Quality Enhancement Activity – SQL08 – Intercropping to improve soil quality and increase biodiversity Enhancement Description This enhancement involves the use of intercropping principles, growing two or more crops in close proximity to each other, to promote interaction resulting in improved soil and water quality while increasing biodiversity. Land Use Applicability Cropland Benefits Incorporating intercropping principles into an agricultural operation increases diversity and interaction between plants, arthropods, mammals, birds and microorganisms resulting in a more stable crop-ecosystem. This collaboration that mimics nature is subject to fewer pest outbreaks; improved nutrient cycling and crop uptake; and increased water infiltration and moisture retention. Soil quality, water quality and wildlife habitat all benefit. Conditions Where Enhancement Applies This enhancement applies to all crop land use acres. Criteria One or more of the following intercropping systems will be used; systems can be mixed during the contract period allowing for a different system to be used each year on the same field. 1. Relay inter-cropping – the growing of two or more crops on the same field with the planting of the second crop after the first one, e.g. over seeding of a clover cover crop into cotton during defoliation, or planting of clover at lay by time of corn. 2. Row inter-cropping – the growing of two or more crops simultaneously on the same field with at least one crop planted in rows, e.g. planting corn in the rows and inter-seeding sorghum between the rows, harvesting all as silage or planting clover in between orchard tree rows. -

Section Five
SECTION FIVE irrigation Water ManageMent Planning Georgia’s agriculture industry utilizes millions of gallons of water each year for irrigation purposes. Ir- rigated agriculture ranges from row crop farming to plant nurseries to orchards. Much of the concern with irrigation is with regard to efficiency, runoff and the capture and collection of runoff. Many irrigation systems are inefficient and essentially waste water during the irrigating process. Ir- rigation efficiency may seem complicated; many producers may feel that their systems are simply too old to modify. In today’s agricultural industry, producers have numerous opportunities to improve the efficiency of their system in a cost efficient way. Improved nozzles, metering, and computer software are all readily available to provide producers with a more efficient means of irrigating their cropland and monitoring plant water use. Planning an irrigation schedule that best utilizes available water can reduce waste and runoff. Irrigation systems need to be routinely checked to ensure that water is being distributed uniformly and that there are no damaged pipes, sprinklers or nozzles. Irrigation meters provide producers with an accurate measurement of the amount of water that is applied to their crops and can also help identify pumping problems within their system. More information on the benefits of metering can be found in the UGA CES document, Water Meters as a Water Management Tool on Georgia Farms. An efficient system should range between 80 and 92% efficient. If a system is less than 80% efficient, producers should consider a system upgrade. There are several government sponsored irrigation system audit programs available and most system manufacturers can assist with an audit program. -

Classification of Botany and Use of Plants
SECTION 1: CLASSIFICATION OF BOTANY AND USE OF PLANTS 1. Introduction Botany refers to the scientific study of the plant kingdom. As a branch of biology, it mainly accounts for the science of plants or ‘phytobiology’. The main objective of the this section is for participants, having completed their training, to be able to: 1. Identify and classify various types of herbs 2. Choose the appropriate categories and types of herbs for breeding and planting 1 2. Botany 2.1 Branches – Objectives – Usability Botany covers a wide range of scientific sub-disciplines that study the growth, reproduction, metabolism, morphogenesis, diseases, and evolution of plants. Subsequently, many subordinate fields are to appear, such as: Systematic Botany: its main purpose the classification of plants Plant morphology or phytomorphology, which can be further divided into the distinctive branches of Plant cytology, Plant histology, and Plant and Crop organography Botanical physiology, which examines the functions of the various organs of plants A more modern but equally significant field is Phytogeography, which associates with many complex objects of research and study. Similarly, other branches of applied botany have made their appearance, some of which are Phytopathology, Phytopharmacognosy, Forest Botany, and Agronomy Botany, among others. 2 Like all other life forms in biology, plant life can be studied at different levels, from the molecular, to the genetic and biochemical, through to the study of cellular organelles, cells, tissues, organs, individual plants, populations and communities of plants. At each of these levels a botanist can deal with the classification (taxonomy), structure (anatomy), or function (physiology) of plant life. -

Carman is an emeritus professor in the Department of California’s agricultural output, accounting for 7.5 of Agricultural and Resource Economics at the University percent of the state's farm sales. Annual sales of $3.5 of California, Davis, and a member of the Giannini billion mean that California accounts for 20 percent of U.S. Foundation of Agricultural Economics. Hoy can be sales of nursery and floral products. Nursery and flower contacted by email at [email protected]. production occurs throughout California, but is mostly concentrated in Central Coast and South Coast counties near the largest population centers; a third of sales are in San Diego County. Nursery and floral production is an important component of California’s overall agricultural output and annual farm income. California’s nursery and flower crops returned average cash revenues of over $3.73 billion annually for the five crop years 2013 through 2017.
