Fertilisation

The coming together (fusion) of male and female cells to create the start of new life; they form a zygote which is the name of the combined cell. Sometimes this term is incorrectly used to refer to fertiliser application.

  Fibrous Thatch

A dark brown, relatively coarse textured organic layer which is associated with drier, acidic soil conditions on which Fescue and Common Bent grass grow. This can also be referred to as Fibre.

  Field Survey Techniques

Specific survey sampling techniques and designs that can be used for sampling the subjects of interest, especially plants and animals, include: 1. Sampling of plants: • Quadrat. • Transect - line/belt. • Plotless. 2. Sampling designs: • Random sampling. • Systematic. • Stratified random. 3. Sampling of animals: • Small mammals (live traps). • Birds (observational count) - line transect. • Invertebrates: Tree beatings; Sweep netting; Malaise trap; Pitfall traps. • Large mammals (including people): Observational count. Advan

  Field Survey: Impacts of Site Work

The environmental impact of any site work on a field area may range from negative (insignificant to severe), to positive where beneficial improvements are carried out. During the survey stage it is important to consider any negative impact you may have from being on site, for example: Don't drive vehicles off roads or tracks, park around the edge or off site, if practicable. Be careful walking around the site, taking care not to disturb nests, dens or frighten animals. Don't pick vegetation - take photographs. Do not leave any equipment or tools, for example stakes or rope, onsite, and

  Field Survey: Purpose and Planning

Firstly consider the question, ‘What is a Survey'? This is a method of collecting data which aims to be representative of the subject of interest. Survey techniques can include: • Questionnaires. • Interviews - structured (from a set of prepared questions) or unstructured (discussion and prompting). • Field Survey Techniques (i.e. physical assessments). • Observation (including measuring). • Analysis of secondary material including official records. • Panel/focus group. Surveys can be used for a wide range of purposes, including: • As par

  Flaccid

Plant cells are short of water and have become weakened. Leaves have difficulty supporting themselves and often flop over as they start to Wilt.

  Foaming Agent

A substance which creates a foam when mixed in a substance and helps to reduce the surface tension of a liquid making it potentially provide more contact with vegetation it is being applied to. Foaming agents may sometimes be part of a pesticide mixture.

  Foliar Burn

Damage to leaves, often leading to their death. This is typically seen through overapplication of a fertiliser, fertiliser spillage, waiting too long to water in some types of fertiliser, incorrect pesticide application, engine oil or hydraulic oil leakage.

  Form

A reference to either 'Fertiliser Form' or 'Plant Form'.

  Forma

The smallest classification grouping which may have an isolated or infrequent minor variation from the standard species and is used to identify minor variations of sub-species or varieties. The term is often abbreviated to f. and being written in italics.
