soil and minerals nutrients
soil
minerals
major source of nutrient needed by plant for growth
major elements
phosphorous
potassium
nitrogen
calcium
magnesium
sulphur
nitrate is the form that plant use.
helps foliage grow strong by affecting the plant leaf growth development
it helps plant by giving green color by producing chlorophyll
helps plant withstand the environmental stress and harsh winters
phosphorous is responsible for assisting with the growth of root and flowers
it also affects the plant disease and insects suppression.
strength plant, contribute the early growth and retain the water
it contributes in green coloring of plant
it aids in the growth and development of the cell walls
this is key because well developed cell wall help resist disease
it is necessary for the metabolism and "uptake of nitrate"
helps plant resist disease grow and from seeds.
they also aid in the production of amino acids, proteins, enzymes and vitamins
helps plant carry oxygen around the all of the cells.
absorbs minerals by osmosis
it works in concert with others minerals to produce chlorophyll and aids in the metabolism of sugar and other carbohydrate.
slit
clay
sand
function
the best soil for most of the plants to ensure optimum growth is rich is loam
soil is even better when 3 types of soil mixed, which is called loam soils.
regulator of water supplies
recycler for raw materails
habitat for soil organisms
landscaping and engineering medium
full of minerals, this soil is fertile but quickly gets cold and water logged in winter
in summer, bakes to a crust
sticky mud that we can roll to a sausage is clay soil
slit is fertile and holds water and is easy to compact
slit soils have silky consistency
sandy soil is warmer
it is free draining and air trapped within it.
has much higher minerals grains than slit and clay.
low in nutrient and dries quickly and often acidic
sandy soil is gritty and crumbly in texture.
peat soil
chalky soil
full of dark organic matter and
holds a lot of water
consistency of these soil varies considerably is the precise makeup some are heavy, light but chalky soils tends towards alkalinity
loam
Combines elements of sandy, clay, and silt soils to produce the best of all worlds, a soil that’s moist, fertile and drains well.
acid and alkaline soils
acid
alkaline
Soils which contain significant quantities of chalk or limestone have a higher pH value – they’re alkaline soils.
And while adding organic matter will help balance the soil over time
If there’s a lot of organic matter breaking down in your soil, it will tend to have a lower pH value.
just because your soil is a little on the acidic side doesn’t mean there’s nothing you can grow in it.
examples magnolias, heather, rhododendron
examples lavender, honeysuckle, liac
