Watermelons need A LOT of space—up to 20 square feet per plant. Their vines need room to sprawl, so plant them in a place where they won't crowd out other crops. Growing the vines in raised rows, known as hills, ensures good drainage and will hold the sun's heat longer. Plan to space the plants 2-3 feet apart in a 5-foot-wide hill.

Weather systems are simply the movement of warm and cold air across the globe. These movements are known as low-pressure systems and high-pressure systems. High-pressure systems are rotating masses of cool, dry air. High-pressure systems keep moisture from rising into the atmosphere and forming clouds.

A crystalline mineral commonly forms under conditions that do not permit it to become a well-shaped crystal. Although the mineral may show a few crystal faces, it does not have a complete crystal shape and so is described as massive, or is said to occur in masses. Some of the minerals that make up rocks occur as crystalline masses.

Earth's most important iron ore deposits are found in sedimentary rocks. They formed from chemical reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides: hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). These iron ores have been mined to produce almost every iron …

Most of the time, we test for runoff pH to gauge fertilizer building up in the soil, which causes it to get very acidic as well as exert osmotic pressure on the plant. Measuring the input and runoff EC is a much better way to tell. If the runoff has a higher EC than the input, you have fertilizer buildup. Check the runoff pH to see how bad it ...
