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

Organisms are open systems that interact continuously with their environment. The study of the interaction between organisms and the environment; the connectedness between living systems and non-living systems on the Earth is called ecology. The term “ecology” which was coined by Ernst Haeckel comes from the Greek root words oikos logos literally meaning “the study of household”. Haeckel was referring to the interactions within the house of nature and we have used the word ecology (translated from

gathered 25 lima beans and made 5 groups for different calcium concentrations (0 mg‚ 100 mg‚ 200 mg‚ 300 mg‚ 400 mg). I used constant variables such as the amount of water‚ soil‚ and light to ensure the accuracy of the results. The growth of the lima beans was recorded over a period of 5 days. Hypothesis: If calcium is added to the soil in greater amounts (0mg‚ 100mg‚ 200mg‚ 300mg‚ 400mg)‚ then the lima beans will grow healthier and taller because calcium aids in the uptake of nutrients in plants. Rationale:

Organic Mulch for Tomato Plants Abstract Mulching in agricultural provides a safe yet equally profitable method of enriching and fertilizing the soil planted with crops. Most often-used mulches are of organic composition‚ such as dry leaves and barks. Unlike synthetic fertilizers and herbicides‚ these organic mulches pose no or little damage to the soil and crops. In this study‚ the effectiveness of dried papaya leaves as organic mulch for tomato was tested. Papaya mulches in different thickness

As part of a five-state region affected by severe drought and soil erosion‚ the "Dust Bowl" as it was called was result of several factors. Cyclical drought and farming of marginally productive acreage was exacerbated by a lack of soil conservation methods. Because the disaster lasted throughout the 1930’s‚ the lives of every Plains resident and expectations of farming the region changed forever. The settlement and development of the Southern Plains came relatively late. Not recognizing the problems
