  15. Weeds

The Core Modules in Detail

The 15 lessons are divided into the following 6 areas:

1. Introduction to Plants

The purpose of this study area is to explain the binomial system of plant classification and demonstrate identification of plant species through the ability of using botanical descriptions for leaf shapes and flowers.

2. Plant Culture

The purpose of this study area is to demonstrate the ability to care for plants so as to maintain optimum growth and health while considering pruning, planting, and irrigation.

3. Soils and Plant Nutrition

The purpose of this study area is to provide students with the skills and knowledge to identify, work with and improve the soil condition and potting mixes, and to evaluate fertilisers for use in landscape jobs to maximise plant growth.

4. Introductory Plant Propagation

The purpose of this study area is to improve the student's understanding of propagation techniques with particular emphasis on cuttings and seeds. Other industry techniques such as grafting and budding are also explained.

5. Identification and Use of Plants

The purpose of this study area is to improve the student's range of plant knowledge and the plant use in landscaping and the ornamental garden, and the realisation that plants have optimum and preferred growing conditions.

6. Pests, Diseases and Weeds

The purpose of this study area is to introduce and help the student in identifying, describing and controlling a variety of pests, diseases and weeds in ornamental situations and safety procedures when using agricultural chemicals are explained.

STREAM MODULES

After completing the core modules, stream modules cover more specific niche subjects:-

THE SCOPE AND NATURE OF CROPS

The range of things grown as crops is huge, and the ways in which crops might be grown is also very diverse. Crops can include:

Vegetable Crops
Vegetables are mostly small plants frown for edible roots, stems, leaves and/or fruits. They may be eaten fresh or processed and preserved to produce marketable products.

Fruit and Nut Crops
These include a wide range of fruits and nuts, mostly grown on trees, but also shrubs, vines and some other types of plants. Like vegetables, these may be sold fresh or processed. Nuts can produce not only the fresh or dried nuts, but also nut meal (a flour substitute) and nut oils.

Fruits are processed and sold as dried, frozen or juiced products; made into wines, jams and other types of preserves. 

Cereal Crops
Cereal crops are grasses that produce edible starchy seeds. Cereals can be utilised as human food or as animal feed that is eventually converted into dairy, poultry or meat products for human consumption. The most common examples of cereal crops are wheat, barley, rice, and corn.

Oil Crops
These include oilseeds (e.g. Sunflower), herbs (e.g. Lavender) and other plants (e.g. Olive trees) that are grown for the extraction of oil from the harvested seed.

Fibre Crops
Fibre crops are grown for fibres, used to make cloth, paper, rope, twine, and other such materials. Single celled short fibres come from the seeds of cotton plants, which are mostly used in fabrics. Long hard multiple celled fibres crops such as hemp are used as ropes or cords, whereas soft multiple celled fibre crops such as flax is used to make linen, and some softer hemp fibres can be used in the manufacture of canvas. Cotton is the most common crop used for textile fibre. It is also an oilseed crop as cotton seed oil has a number of uses, such as cooking oil, is used to manufacture cotton seed oil soap and is also used as a high protein stockfeed.

Legume Crops
Legumes are particularly valuable crops. Legume crops are a broadleaf crop (not a grass crop) that is grown for grain, grain products and oilseeds. They are also grown as fodder crops and hay for stock. Legumes are unique in that they have a symbiotic relationship with rhizobia (a nitrogen fixing bacteria that forms on the plants roots) that allows them to fix atmospheric nitrogen. That is, through their symbiotic relationship with the rhizobia, they are able to fulfil their nitrogen requirements through atmospheric nitrogen rather than extracting nitrogen from the soil profile, which over time depletes soil nitrogen reserves. Legume seed and foliage is higher in protein than non-legume seed and foliage, which makes legume crops highly desirable in agriculture. Chickpeas and lentils are a common example of a grain legume used for human consumption, Lucerne and cowpeas are an example of a legume fodder crop, and soybeans and peanuts are an example of an oilseed legume.

Fodder Crops
Fodder crops are grown specifically for animal food, They may be cereal crops (e.g. oats and forage sorghum) or they can be legumes (for example lucerne and cowpeas). They can be any combination of these types of plants, but are specifically grown for the purpose of stock feed. Fodder crops can be fed directly to livestock as green chop or they can be cut and stored into a longer shelf life form of feed such as hay and silage.

Forage crops and fodder crops can be the same type of crop but the pertinent difference is that forage crops are usually standing in the field where the onus is on the animal to forage for their feed (grazing), whereas fodder crops refer to the collection of green leaf material transported to the animal for consumption by the animal.
