Hemp is a crop that has been cultivated since many centuries for its fiber and seeds. Being a cannabis plant, hemp is a rich source of various cannabinoids including CBD. After the US government has legalized the production and sale of hemp-derived CBD products, the farmlands growing hemp expanded rapidly.
Here, we are discussing the ways in which hemp cultivation benefits the soil.
Hemp has long been used for killing weeds on the farms. Due to its high planting density, height and dense foliage, the crop proves very effective in checking the growth of weeds in the soil. Even thistles cannot survive in an area with a dense growth of hemp. Because hemp itself is capable of checking weed growth, herbicides are not really needed and the reduced use of herbicides will have a positive impact on soil fertility.
Loosens The Soil Compatibility And Enhance Nutrient Distribution
A mature hemp plant grows up to a height of 5 meters and its main tap root system grows down to a depth of up to 1 feet. Due to its deep roots, hemp plants can draw nutrients that are buried deep inside the soil and distribute them to other crops on the farm, especially when the hemp leaves are shed on the soil. Its extensive root system also solves the issue of soil compaction.
Do Not Alter The Soil Features Much
Hemp requires little or no fertilizer for its growth. The crop encourages less runoff into the waterways and groundwater. Thereby hemp can be grown on the same land for a long time without experiencing any decrease in yield. Hemp is known to be resistant to increased UV radiation and thus its yield does not decrease due to exposure to UV light unlike crops like corn and soybeans.
Easy To Grow
As hemp does not require any pesticides for its growth, it is regarded as an economical crop. Hemp when dried in the soil returns about 60% of the nutrients it drew from the soil. The crop has been very useful in circumstances of drought-induced famine because it has appreciable drought-resistance and produces nutritious seeds.
Hemp is also known as a crop that is ideal for crop rotation because it aerates the growing soil and deposits carbon dioxide in it. The high demand for hemp-derived CBD products has encouraged many people to grow hemp on their lands.
