What is the nitrogen cycle?
Nitrogen is a gas produced from animal, plant, wood ash, and human waste. Plants need the nitrogen which supplies energy to grow and bear fruit. It is the primary chemical needed in photosynthesis, so, it is pretty important for good growth.
Generally, plants and animals eliminate waste (nitrogen) and it seeps into the earth. Bacteria break down the wasteand it creates nitrates. When nitites are created, they are absorbed and used by plants to help create food and energy for the plant (photosynthesis). Further, excess nitrites in the form of gas are released into the atomosphere. The gas particles are held in the atmosphere until rain in the atmosphere washes the nitrites into the ground, encouraging more rapid growth in plants and trees.
So, if you are having a drought, or your climate is dry and arid, you may need to add nitrogen along with your extra watering. Watering alone will not suffice to help your garden grow.
What can you add to your garden to encourage the nitrogen cycle?
Cottonseed meal (usually needs to be purchased)
Allow animals such as chickens and/or cows or goats to wanter in your garden during the off-seasons of growth
Add additional manure from outside sources
Add a layer of grass clippings or leaves
Plant legumes, which naturally add nitrogen back into the soil.
Spread out coffee grounds
Spread out compost
