So, how do Coastal Redwoods get so big? Well it’s not the N-P-K that you’re putting on!
First of all, these monsters are so big that they need a ton of water. Water is the medium for photosynthesis, nutrient transfer, germination (redwoods are conifers – they produce cones) and transpiration. Transpiration is the movement of water and nutrients from the soil via the roots.
Trees move water from the soil to their branches and leaves via small capillaries, called xylem channels, which for these giants require some major suction. This is accomplished by the stomata (tiny pores on the underside of a leaf) which open to take in carbon dioxide, allowing water to evaporate from the leaf. The evaporation creates negative pressure within the xylem, and thus water is pulled up the tree. Nature can be pretty darn cool.
How do these giant trees continue to grow without all the inputs of modern farming? Well, it’s the biology in the soil that helps the trees convert carbon to sugars to feed the expansive world beneath your feet which, in turn, mineralizes the nutrients the trees need to survive and be healthy.
Andaman Ag is constantly working with growers to supplement their conventional practices with products and practices that will enhance soil health. Healthy soil improves nutrient mineralization and stimulates maximum photosynthesis, which leads to better crop yield and quality. As Gary Zimmer notes, it’s management, balance and efficiency that makes farming profitable. Over time, as soils improve and are more efficient, less costly inputs are required as crop quality and yields naturally increase.
There is no question that regulation will continue to encumber our lives, and restrictions on the use of certain materials and on water access will always be of the highest concern. Incorporating biological farming practices will help farms continue to improve and utilize less water, as it’s a simple fact that organic matter holds more water right where in needs to be located. Adding biologicals to your conventional mixes will magnify their results whether that’s CAN17 or UAN-32. For example, applying these products in conjunction with Pacific Gro oceanic hydrolysate and MetaGrow ST compost tea will deliver improved performance.
Redwood trees live in an ecosystem that supports life. Ultimately, that’s the objective of any farm – supporting a robust ecosystem that promotes pollinators and other beneficial insects, and suppresses disease and pest pressure. Our magnificent redwood soldiers have taught us that soil biology can have a tremendous impact.
