Insufficient soil is one of the main reasons why fruits, vegetables and flowers struggle to grow to their full potential. Land areas of all sizes, from large gardens to gardens in the garden, will need fertile soil to provide healthy yields. Organic fertilizers and can provide a need for boost, but they can be expensive, especially in large quantities. Fortunately, growing the right plants with the right technology can enrich soil by drawing elements and nutrients directly into the dirt.
What does healthy soil do?
Organic materials are the most important ingredients for healthy soils, which in turn make healthy plants. Farmers and gardeners will focus on the "N-P-K" (nitrogen-phosphorus-potassium) ratio for plants and fertilizers to increase some crop growth. Nitrogen must be replenished most, making it one of the more important elements to consistently add to your soil.
Nitrogen fixation plants
Nitrogen fixation plants are important for working gardens and farms. Many are used in the form as cover crops. When decomposed, they increase the amount of available nitrogen in the soil for other plants to use. These "nitrogen fixers" have a symbiotic relationship with bacteria that other plants do not, making them very useful for depleted soil.
Types of cover crops  Cover crops are specific plants grown between planting seasons to provide depleted soil much needed rest, nutrients increase and to improve their structure. Cover crops differ from food crops in that they are cut or killed before going to seed so that their useful energy is recycled in the country. Some cover crops fix nitrogen, while others are good ways to add bulk organic matter via biomass (leaves and leaves), and others do both. Cover crops can also act as a layer of nutritious mulch to spread over crops (hence their name), which not only controls weeds but will continuously release nutrients into the soil as they decompose.
Clover is generally a well-known and frequently used cover crop, since their leaves leave a particularly high amount of nitrogen compared to other plants when they are decomposed. Clover is usually planted in the fall and chopped up to spring soil a few weeks before planting. Crimson clover and red clover are the most popular varieties depending on the region to help with nitrogen fixation, moisture retention and weed prevention.
Other legumes such as cowpeas, soybeans and alfalfa are also nitrogen-fixing and can be planted at different times of the season to keep a garden or yard continuously active. They often grow in shade and are hardy plants that can be used in crop rotation, as soil builders or as fodder crops.
These plants are known to grow well in poor soil and help revive soil quality as they grow year after year. Most will have deep taproots that provide nutrients buried too far down for most plants to come back to the surface. You can also cut them often and use the biomass to return organic matter and nutrients back into the soil as they decompose.
Known as a groundhorse workhorse, comfrey is one of the most common plants for rapidly rejuvenating the soil. Its root system can extend over six meters underground and collect deeply buried nutrients and call them back to the surface of its foliage. It also provides a large amount of biomass in just months, as it regenerates its leaves quickly after it has been cut.
These perennials are also food hunters, but as their names suggest, they can sting your naked skin. If you are willing to take on the challenge, be sure to dress appropriately as you reduce them. The effort will be worth the nutritious organic material that goes back to your garden.
This edible plant is often regarded as a weed, but has many virtues skilled gardeners honor. Its deep root system pulls nutrients up to the surface and can be chopped or torn back into smaller gardens.
This "nitrogen fixer" acts like clover and legume, and it is very hardy. Mature plants will grow to eight meters tall which means that they also provide a high amount of biomass – you can cut them several times during the growing season.
Crop rotation and forage cultivation
Farmers use crop rotation by then planting different crops in the same area to help replenish nutrients. A very common example is planting soybeans after a season of growing corn, because soybeans are a nitrogen-producing plant while maize is a heavy nitrogen user. Crop rotation also helps reduce erosion and improve soil structure.
Feed crops are plants left for nature to use, primarily through feed such as livestock and other wildlife, instead of being processed or used as mulch. When forage crops are used in crop rotation methods, the soil can be improved by enriching and adding fertility, breaking up clay and preventing soil erosion.
Depending on what your garden or yard needs most, the right kind of forage crops can either fix nitrogen or add the required organic material. Legumes such as peas and beans are nitrogen fixers that will enrich the soil. Cereals such as rye, wheat, barley, buckwheat and oats add organic bulk. Daikon radishes grow well in clay soils and break them up when they decompose – this adds much needed pathways for water and nutrients to enrich the soil structure. Many gardeners and farmers try a mix and match strategy to find a balance between the benefits between cereals and legumes.
Think about how much biomass you can handle and how much nitrogen the soil needs, and plant only what you can handle with your tillers and space requirements. Soil testing can be a useful tool to find out what new plots and overworked farmland may require. Once you have figured out what your land needs, you can develop a rhythm to plant the right things every year to make sure your soil is always healthy.
