Phytoremediation & Bioremediation

Phytoremediation and bioremediation are quickly gaining ground in the reclamation and remediation industry as being a simple, hassle-free way of dealing with site contamination. If a consultant can get carefully chosen plants or microbes to do the work for him, it cuts down on manpower and increases efficiency.

Alfalfa Green has several properties that make it ideal for phytoremediation and bioremediation  projects, icnluding:

1) A neutral pH- Alfalfa Green helps maintain a neutral soil pH, making the soil conditions the perfect environment for microbial interactions, chemical reactions, and plant nutrient uptake. A neutral pH means the ideal balance of minerals and nutrients are in their bioavailable forms, and microbes flourish Chemical reactions such as the cation exchange complex also function best at neutral pH.

2) Organic matter- The addition of heat-processed plant fibers boosts microbe activity by providing a food source for the soil microorganisms. As they digest the Alfalfa Green, their other functions increase in tandem. Processes such as hydrocarbon degradation or nitrogen fixation get a kick-start. As organic matter increases in the soil, overall soil structure improves and allows for increased chemical, biological, and physical reactions. In clay soils, soil aggregates become smaller in size which allows for more surfaces for cation exchange. Sandy soils see an increase in the size of the soil aggregates which allows for increased cation exchange and the creation of a variety of pore sizes. The soil pores are where the many components of the soil ecosystem interact. Increasing pores improves soil science, making the perfect environment for root growth and expansion. Improving the soil structure also enhances the moisture retention and moisture adsorption.

3) Nutrients- Alfalfa Green delivers over 20 macro and micro nutrients, including amino acids and plant-available forms. Aside from the usual N-P-K, Alfalfa Green slowly releases a broad range of nutrients such as calcium, selenium, and magnesium.
