Optimizing Plant Health with Foliar Feeding: A Regenerative Approach at Brow Farm Ltd

Foliar Feeding: Enhancing Plant Health and Photosynthesis at Brow Farm Ltd


Foliar feeding is a method of providing essential nutrients to plants by applying liquid fertilizers directly to their leaves. This technique is particularly effective for quickly addressing nutrient deficiencies and optimizing plant health. At Brow Farm Ltd, we integrate foliar feeding into our regenerative farming practices to keep our plants working at their best and to maximize photosynthesis.

What is Foliar Feeding?

Foliar feeding involves spraying a nutrient solution onto plant leaves, allowing them to absorb nutrients directly through their stomata and cuticles. While roots are the primary means for nutrient uptake, foliar feeding serves as a supplemental method, especially useful for rapid correction of deficiencies.

Interaction with Soil Life

Adding foliar feeds to plants does not stop the plants from interacting with soil life for nutrients. Foliar feeding provides a supplemental source of nutrients. While plants can absorb some nutrients through their leaves, they primarily rely on their roots for nutrient uptake. Soil microorganisms, such as bacteria, fungi, and other organisms, play a crucial role in making nutrients available to plants through processes like decomposition and nutrient cycling. Plants and soil microorganisms have evolved a symbiotic relationship where plants exude certain compounds from their roots to attract beneficial microbes that help with nutrient uptake. Foliar feeding can be beneficial for providing a quick boost of nutrients, particularly if a plant is experiencing a deficiency that needs to be addressed rapidly. However, it doesn’t replace the comprehensive nutrient uptake system that plants have developed through their roots in collaboration with soil life. Thus, the application of foliar feeds can complement soil nutrition but does not negate the plant’s need for healthy soil and its microbial interactions.

Our Regenerative Approach at Brow Farm Ltd

At Brow Farm Ltd, we believe that foliar feeds are an important part of our regenerative approach to farming and growing crops. Regenerative farming focuses on restoring and enhancing the health of our soil, plants, and ecosystems. By integrating foliar feeding into our practices, we ensure that our crops receive the nutrients they need to maintain optimal photosynthesis and overall plant health.

Foliar Feeding for Optimal Photosynthesis

Maintaining high levels of photosynthesis is crucial for plant growth and productivity. Foliar feeding helps us achieve this by providing plants with readily available nutrients that support their metabolic processes. This method is particularly useful during key growth stages or when environmental conditions might limit nutrient uptake through the roots.

Strategic Use of Nitrates and Urea

While we primarily use foliar applications to keep our plants working at their best, we recognize that nitrates and urea can play a role in specific situations:

  • Nitrates: We do not advocate for the continuous use of nitrates to boost plant growth over time. However, nitrates can be applied through foliar feeding to produce a growth reaction within the plant or at a specific time during its growth cycle when a quick nitrogen boost is needed.
  • Urea: Similar to nitrates, urea can be used strategically to address immediate nitrogen deficiencies or to support specific growth phases. When applied as a foliar feed, urea must be carefully managed to avoid leaf burn and ensure effective nutrient absorption.


Foliar feeding is a valuable tool in our regenerative farming toolkit at Brow Farm Ltd. It allows us to provide essential nutrients directly to our plants, supporting their health and maximizing photosynthesis. While nitrates and urea have their place in specific, targeted applications, our focus remains on using foliar feeding to enhance overall plant vitality and maintain sustainable farming practices.
