The answer is oil.
The United States' fossil shortage of oil makes the country dependent on outside sources. Mineral oil such as crude oil or commonly known as petroleum came from the ancient fossilized organic materials. This resource is limited. The US is now facing a shortage in oil and becoming dependent to some countries such as middle-east countries.
The gardener should address the measurements he needs to make so that planting information is clear, and that the roots are spaced to grow.
<h3>How to calculate amount of landscaping plants?</h3>
just divide the area of the bed by the area occupied by the seedling and we will have the total amount of seedlings to be used. In this way, we also understand that the area occupied by the seedling is equal to the spacing between seedlings raised to the square.
<h3>How to calculate the spacing between plants?</h3>
If we plant with a spacing of 0.60 meters, the number of seeds per meter will be calculated as follows: Being 1 hectare = 10,000 square meters and the spacing between rows of 0.60 m, we have the equivalent of a range of 0, 60 meters by 16,667 linear meters (10,000 divided by 0.60).
With this information, we can conclude that the area occupied by the seedling is equal to the spacing between seedlings raised to the square.
