Standard 4 Objective 2Slide2

Soilless Media

When raising plants there are many different options for a growing media

Most of the time think all plants grow in soil

This is not the case

Does anyone know the kind of growing media we commonly use in our greenhouse?

Is is soil? or a Soilless media?Slide3

Composition of Potting Mixes

Soil (loamy, good structure, pesticide-free)

Coarse aggregates for drainage (sand,

perlite

, vermiculite, shredded plastics)

Organic amendments to hold water (sphagnum peat moss, tree bark, sawdust, rice hulls, shredded coconut hulls, wood chip/sludge compost

)

Most contain no soil Slide4

Advantages of Soilless Mixes

sterile

lightweight

good moisture retention and drainage

free of weed seedsSlide5

Disadvantages of Soilless Mixes

minor

elements are missing

light

weight - pots tip in strong

wind

transplants may not adjust well to new mediaSlide6

Content of mixes

Soilless mixes contain various combinations of the following materials.Slide7

Perlite

improves aeration

of volcanic originSlide8

Spahgnum Moss

Dehydrated remains of acid bog plants

Used to cover seeds because it is lightweight, controls disease, and holds moisture.Slide9

Peat Moss

Partially decomposed underwater vegetation.

Holds moisture well

Low in nutrientsSlide10

Vermiculite

Exploded Mica

Improves aeration

Holds moisture very wellSlide11

Limestone

Raises pHSlide12

Hydroponics
