The plants to help them grow.
A gritty compost which promotes drainage is the type of compost which an olive tree needs. The woody plant in question prefers a soil whose pH is in the neutral or slightly alkaline ranges. It requires proper infiltration and percolation of water and therefore needs grittiness to prevent waterlogging.
Adding nutrients and altering the pH are reasons for adding fertilizer and limestone to a compost pile. But if proper procedure is being followed under appropriate conditions, the compost pile needs no such supplements.
A compost bin needs air holes to allow oxygen to enter the compost pile. Oxygen is necessary for the decomposition process carried out by microorganisms in the compost, helping to break down organic materials effectively and prevent the pile from becoming smelly or anaerobic.
A compost pile is compost in a pile or heap. a compost pit is compost in a pit or hole in the ground.
The heat stays mostly inside the compost, that's why it is important to turn the compost inside out regularly, so that every part of the compost gets sterilized from bad germs. In open air compost heaps, the heat will evaporate as vapor, especially visible in cold weather. That water loss needs to be compensated. There is probably not much residual heat at the surface of a compost bin. Heat usually goes up, but in that case, the heat is not in air or water, but in the mass of the compost itself, so it radiates in all directions. A small container such as a compost bin would see most of the heat exchanged from every side.
Aged garden is the kind of compost mix to buy (or make) for roses in a tub. Gravel needs to be on the bottom, which then is topped with a mix of one-third each of clay, decomposed compost, and sand for proper aeration, drainage, moisture, nutrients, and weed control.
The decay process needs oxygen for it to happen. The surface of the compost heap will decay faster than the material 'buried' deeper in the pile. Regular mixing of the compost ensures air gets right into the heap - speeding up the decay process.
Yes, a compost bin needs holes for proper aeration and drainage to ensure that the composting process is efficient and successful. These holes allow oxygen to enter the compost pile and excess water to drain out, creating the ideal conditions for decomposition.
Compost.
Compost produces compost, a light top soil super rich in nutrients and in humus. The compost comes from decomposed vegetal and usually animal material. Basically, the vegetal material provides the carbon that the decomposing bacteria need, and the animal material provides the nitrogen it also needs to build cells, although in a much smaller ratio. Once all the organic material is fully decomposed and transformed into humus, the bacteria die and add their own dead bodies to the amount of nutrients available to the plants when the compost is finally spread on the soil.
Locations convenient for access but secluded from neighbors, traffic, and winds are places where compost manure can be set up. Compost manure particularly must be monitored for being employed timely before going stale. Its location needs to be one that will not attract pathogens or pests.
Cedar Grove offers several kinds of compost. They sell landscape mulch, organic compost, compost with manure and compost mixed with sand. One can order the compost online.
