Good drainage

For water spray protection over tlie entire surface area of tlie tank designed witli a density of 0.25 gpni/ft or more F=0.3. For an approved fire resistant installation, F=0.3. For an underground or buried tank, F=0.3. For water spray witli good drainage F=0.15. 

These are the basic formulas for the usual installation, with good drainage and available fire-fighting equipment. These formulas are plotted on Figure 7-30 showing curv es for Q for various values of factor F. The approximate amount of insulation corresponding to the factors is indicated. 

Control valves for deluge Manual fire protection Separate units Place shutoffs well away from process areas. Install hydrants, monitors, and deluge systems. Add good drainage. Separate (space) plants on a site, and separate units within plants. Provide access from two sides. 

Worm bins can be purchased, or you can make your own—or adapt existing containers such as wooden crates or boxes, or a plastic storage bin. As worms like to feed near the surface, the most effective bins have a relatively large surface area. There is no need for the container to be "wormproof" the worms will stay put if the conditions are right for them. Good drainage is vital, as kitchen waste can produce... 

Good drainage is essential, but otherwise plums and their close relatives are not unduly fussy about soil. Japanese and American cultivars prefer sandy or loamy soil, while European cultivars do well in clay soil. 

Raspberries are hardy in Zones 3-9 and fruit in sites that only get sun for half the day. They prefer fertile, free-draining soil with a pH of 6.5 or below. Raspberries are not happy in alkaline soil. Good drainage is vital raspberries are prone to a root rot that thrives in wet soils. 

Sorption is the dominant process controlling partitioning in water and movement in soil. Silver may leach from soil into groundwater acidic conditions and good drainage increase the leaching rate. Silver is bioconcentrated to a moderate extent in fish and invertebrates. 

For earliest color, transplant or seed in full sun. In hot climates plants appreciate some afternoon shade. While calendulas tolerate poor soil, they prefer average soil and must have good drainage. Water regularly, keeping soil slightly moist. When first buds appear, pineh back the main stem to promote maximum flowering. In adverse conditions, such as excess heat, calendulas may still flower, but stems will be shorter. 

To avoid root damage, keep the soil evenly moist. Plant in raised beds to ensure good drainage.
