Soil Amendments

  • About 16% of the world's farmland is free of fertility problems, or "constraints", such as chemical contamination, acidity, salinity or poor drainage.
  • In parts of Asia, as little as 6% of farmland is free of such problems. North America has the largest share of the best land at 29%.
  • Agriculture is being pretty successful at keeping the world in food. It's been somewhat less successful in nuturing the natural resourses that underpin that production capacity.
  • Aluminum contamination is high enough on 17% of the farmland worldwide that it's toxic to plants.
  • Salt deposits are a significant problem on irrigated land. Nearly 4 million acres of farmland is lost to excessive salt every year, or about 1% of irrigated area worldwide.
  • Rhizobia bacteria which live in nodules on the roots of legumes and fix nitrogen from the atmosphere, and the mycorrhizae, small fungal threats which penetrate plant roots and allow nutrients to be transferred directly from the soil into the plant's root system.
  • The use of readily available, soluble mineral fertilizers bypasses or short circuits the biological processes to which the plants have become adapted and makes the nutrients directly available to the growing crop. This can result in luxury uptake of nutrients by the plant, and has consequences not only in terms of the health of the growing crop and its susceptibility to pests and diseases, but also in terms of the quality of the end product.
  • Depletion of organic matter in soil also is widespread, reducing fertility and moisture retention and increasing emissions of carbon dioxide into the air, which is believed a factor in global warming.
  • Chemical fertilizers aren't effective unless sufficient organic matter remains in the ground.
The Strutt report, 'Modern Farming and the Soil', published by the Ministry of Agriculture, Fisheries and Food (MAFF-Great Britain) in 1970, concluded that 'some soils are now suffering from dangerously low organic matter levels and could not be expected to sustain the farming systems which have been imposed on them.' The biological activity of the soil, which depends on the availability of nutrients and energy supplied by soil organic matter and crop and livestock residues, has declined correspondingly. Given that much of the chemical weathering which takes place in soils is the result of the activity of soil microorganisms, then the ability of the soil to supply nutrients to the growing crop from its own reserves is going to be diminished by a reduction in soil biological activity.

CalPhos™ is a naturally occurring combination of phosphorus, calcium and trace minerals.

CalPhos™ has been used for over 40 years as a major nutrient source in some of the finest natural fertilizers. When soil testing shows deficiencies of calcium and phosphate, CalPhos™ is a valuable tool to increase these minerals. Technically, it is known as colloidal phosphate which means that the particles are small and readily available for the plant to use. CalPhos™ is guaranteed to contain not less than 20% total phosphoric acid and 20% calcium with available phosphoric acid of 3%.

CalPhos™ is available in 50 lb bags or 2000 totes.
Bulk shipments by special order [23 Ton-46000 lbs].

  • Bio-Ag Lawn & Garden Mix 0-4-1
  • Bio-Ag’s own specialty, non-burning fertilizer mix composed of all natural ingredients, which can be used on lawn or garden.
Ingredients: CalPhos™, Kelp Meal, Carbonatite, gypsum, Green Rock, Boron, Black Earth, Chelated Trace Minerals and Marl.

Available in 25kg bags
This product is custom formulated to use outside on lawns, vegetable and flower gardens. It contains molasses, nitrogen, phosphorus, minerals, vitamins and micronutrients. These nutrients feed the soil life. With the soil life fed an active, domestic plant growth will excel. GMO free. Minimum analysis 2-2-1 and 3% water-soluble calcium.

Benefits: Less watering. As nutrients are replaced in the soil, particularly carbon, the moisture needs will be reduced. Less cutting of lawns (compared to high nitrogen fertilizers). Less prone to insects, disease, molds, fungus, droughts, etc. The soil microbes will consume more of the thatch layer. Results increase in successive years Fertilizer requirements are reduced or eliminated.

Directions: One 13 kg (10L) container is designed to supply 2,000 to 3,000 square feet of lawn/garden area per year. It is best to use this product after the ground has been worked up. Use half in early spring and the remainder in late spring or early summer.
Bio-Ag offers two foliar spray product options, both manufactured by Acadian Seaplants.  Both products are derived from 100% pure ascophyllum nodosum, which is rich in both micro and macro elements.  They are used most frequently as a foliar spray for agricultural and horticultural crops. 1. Stella Maris Aquatic Plant Extract , 1L or 10L jug
Acadian Organic Liquid Seaweed [0.5-0.2-17] 9.54L jug. Contact your organic certifier prior to using to verify it is acceptable.  Why we recommend these foliar seaweed products:
·       Dissolve in water and will not clog nozzles
·       Increased uptake of trace minerals resulting from foliar feeding
·       Increased marketable yields
·       Improved frost resistance for sensitive plants
·       Enhanced germination and emergence when used as a seed soak
·       Reduced insect damage and prevents fungal diseases
·       Promotes better root growth
·       Is compatible with most herbicides, fungicides and insecticides
·       Increases shelf life for fruits and vegetables
·       Improves plant appearance and colour
What is different about the organic version of this product?
·        No preservatives or sodium hydroxide
·        Must be kept cool and used within a few months
