Envirotree - Plant-Soil Nutrient Exchange

on Wednesday, 23 October 2013.

Photosynthesis draws water & nutrients up from the roots to interact with sunlight and atmospheric gases, producing carbohydrates & certain energy-laden biochemicals.

Sulfur builds chloroplasts used in photosynthesis.

Nitrogen is used throughout the plant & greens up foliage as a component of chlorophyll.

Potassium aids in-plant water flow & reduces water loss from leaves.

Carbohydrates & biochemicals support growth in stem, leaves, roots, fruits, & seeds.

Phosphorus is part of the energy-laden biochemicals used in flower & seed formation.

Carbon increases root zone bioactivity, helping make soil nutrients more plant-accessible.

Organic substances help form aggregate colloids in the soil. Macro & micro pores around the colloids improve mass flow; they also enhance gas exchange, improve moisture penetration & retention, reduce runoff of applied fertility, & foster a favorable environment for increased microorganism activity, furthering the symbiotic plant- bacterial-microbe relationship.

Water moves toward salt (the osmotic effect). It is absorbed by roots when the salt concentration inside the root is greater than the salt concentration of surrounding soil. Unfortunately, irrigation increases soil salts, decreasing the osmotic effect & inhibiting water and nutrient uptake. Fortunately, microbial activity can reduce soil salts & improve the osmotic effect, making soil moisture & dissolved nutrients more readily available to plant roots.

Root exudates feed soil bacteria and microbes, which, in turn, exude plant nutrients in a symbiotic relationship.

Nutrient-rich, nutrient-available soils need lateral movement of water through soil – mass flow - to bring nutrients into contact with root hairs. Under these conditions, aggressive root growth & mass are possible.

Root mass provides anchoring, makes possible the uptake of nutrients & water, & reduces the effect of various stressors by improving disease, pest, & drought resistance.
