Grower experiences have proven milled pine bark to be an excellent growing substrate for southern highbush blueberries. Although milled pine bark shares many characteristics with good blueberry soil, fundamental differences exist and need to be understood for rapid growth of young plants and high blueberry yields.

Sprayer Nozzle Selection
Nozzle selection is one of the most important decisions to be made related to pesticide applications. The type of nozzle affects not only the amount of spray applied to a particular area, but also the uniformity of the applied spray, the coverage obtained on the sprayed surfaces, and the amount of drift that can occur. Each nozzle type has specific characteristics and capabilities and is designed for use under certain application conditions. This publication describes the types that are commonly used for ground application of agricultural chemicals, including flat-fan, even flat-fan and cone nozzle.

This publication covers a procedure for applying wood ash as a lime substitute on agricultural lands. This method can be used by manufacturers and dealers who wish to supply wood ash or by landowners who wish to receive wood ash. If the practices in this publication are followed, there should be no adverse environmental effects or regulatory consequence from the land application of wood ash.

Lime mud is a by-product produced in pulp mills as part of the process that turns wood chips into pulp for paper. The pulp mill cooks wood chips with sodium hydroxide to extract the wood fiber used to make paper from the lignin that binds the wood together. During this process, sodium hydroxide is converted to sodium carbonate. The pulp mill than adds calcium oxide, also known as quicklime, to convert the sodium carbonate back to sodium hydroxide in order to use it again. In the process, calcium carbonate is formed.

A soil test is a chemical technique used to determine the status of available nutrients in a soil sample. It is a common method used to predict how soils will react to the addition of lime or fertilizer and calculate how much of each is required for crop production.

Spinner-disc spreaders are commonly used for applying lime and fertilizer to
agricultural fields. Uniform and accurate application of lime and fertilizer is essential. The
performance failures of agricultural materials can be directly related to improper and uneven
application, careless equipment operation, and the separation of blended material due to size
and density differences. The uneven distribution of lime and fertilizer can reduce yields. Effects
of uneven lime or fertilizer distribution are most notable in fields that are low in soil fertility,
because the response to applied nutrients is greatest on these soils.
Proper setup and calibration of application equipment is important to assess its performance and
attain satisfactory results. Even new and well-maintained equipment needs calibration checks
regularly before and during the growing season. This is especially important when changing
from one type of material or blends to another, when changing application rates, and when
altering speeds or other operating conditions.|

Fertilizer injectors are devices used to apply water-soluble fertilizers, pesticides, plant growth regulators, wetting agents and mineral acids during crop production. They are a vital part of modern greenhouse or nursery operations. Despite the advantages, many growers have had at least one experience with a compromised, damaged or even ruined crop where the cause was traced to a malfunctioning injector. Just like other mechanical devices, proper and frequent maintenance and calibration are crucial steps to ensure optimal injector performance and, thus, healthy crops.
