What is Salinity? Salinity – Salinity can be defined as the condition where the quantity of salt causes problems in the soil and impacts in the landscape. The term salinity can be classified in numerous diverse ways: irrigation salinity‚ dryland salinity‚ urban salinity‚ river salinity and industrial salinity. These contrasting types of salinity are arranged to how and where the salt has been located and what the effects are. An example of salinity is the amount of salt that is measured in a fish

The study presented in this thesis form a relationship between soil chemical properties throughout the years within Giant Miscanthus soil. Miscanthus is a perennial‚ rhizomatous‚ giant grass that was originated from East Asia and now distributed worldwide. This subtropical plant has C4 photosynthetic pathway and can be grown in warm seasonal weather. These perennial rhizomatous grasses are promising energy crops due to their high productivity‚ low nutrient requirements‚ ecosystem services and great

-How plants get liquid and minerals- Flowers absorb liquid through their roots‚ which are attached to xylem vessels. Xylem vessels are tubes that can expand through several feet of tissue and be .7mm in diameter. Their walls are thickened with cellulose deposits. Xylem bring water up to the leaves and petals of the plant. Even without contact with the roots‚ the xylem can still absorb water. Because of this‚ a cut flower usually doesn’t die for a couple days (as long as it is placed in water of

discovered in the 18th century that plants absorb mineral nutrients as inorganic ions in water. Normally soil is thought to be required for plant growth‚ but in actuality‚ soil is not needed at all. When the mineral nutrients in the soil dissolve in water‚ plant roots have the ability to absorb them. When the required mineral nutrients are introduced into a plant’s water supply artificially‚ soil is no longer required for the plant to thrive. Almost any terrestrial plant will grow with hydroponics

Study Questions: 1.) Why is sub-soiling needed in soils with hard pans? Sub-soiling is essential especially to hard pan layer because it will help the roots penetrate deep and be able to explore and obtain water and nutrients from larger volume of soil. Hard span obstructs root’s downward proliferation and restricts root growth of crops (of crops that have vertical root growth). With sub-soiling‚ the needed soil depth‚ at least 80cm will be met . With sub-soiling‚ we can break hard pan without

earthworm casting is a better planting medium than garden soil. Five set-ups were prepared including one control‚ with the same amount of water given and exposure to sunlight and temperature. However‚ they differ in the proportion of earthworm casting in every pot. The earthworm casting and garden soil were weighed and then thoroughly mixed (according to the proportion of earthworm castings‚ 0%‚ 25%‚ 50%‚ 75% & 100%). Each mixture of soil had a total of two kilograms. The mixtures were placed in
