Foliar Spraying of Cannabis Plants: Absorption of Essential Nutrients
Cannabis is a versatile plant that can be grown for its medicinal and recreational properties. Its growth and health are highly dependent on various factors, including soil composition, temperature, light, and nutrients. In this article, we will focus on the importance of foliar spraying in cannabis cultivation and its ability to absorb essential nutrients.
Foliar spraying is a common cultivation technique that involves applying liquid nutrient solutions directly to the leaves of the plant. This method is known to provide faster and more efficient nutrient uptake than traditional soil-based fertilization. Foliar spraying provides an alternative for plants to absorb essential nutrients, particularly in instances where soil fertility is low or when plant roots are damaged.
A study conducted by the University of California, Davis, found that foliar spraying can increase the absorption of certain essential elements, including nitrogen, phosphorus, and potassium, by as much as 50%. The study also showed that foliar spraying can significantly improve plant growth and development, resulting in larger, healthier plants with increased yields (Levine et al., 1991).
Another study conducted by the Humboldt State University in California found that foliar spraying can be an effective method of delivering calcium and magnesium to cannabis plants. These two essential elements are critical for cell division and overall plant health, but they are often difficult to absorb through soil-based fertilization methods (Garten et al., 2017).
In conclusion, foliar spraying is an effective method for delivering essential nutrients to cannabis plants. It can improve plant growth, health, and yields, particularly when soil fertility is low or when roots are damaged. Foliar spraying can increase the absorption of essential elements, such as nitrogen, phosphorus, potassium, calcium, and magnesium, resulting in healthier plants and higher yields.
