BFA Mineral Depot

2017 list of amendments

We are now actively taking orders for Spring 2017.

Note: amendments are for BFA members only, and not available to the public.


About the BFA Mineral Depot
How it works

Our Mineral Depot Program helps connect members with sources of hard-to-find amendments bought in bulk at reduced prices.

Mineral orders are processed twice a year:  Spring orders are due April 1Fall orders are due September 1.

Liquid and inoculant orders will be processed throughout the year on a rolling basis.

Members must work with their local chapters to combine orders using the "Foodclub" ordering system. This helps us get everyone better pricing and much better shipping rates. You can request an account on foodclub here: https://foodclub.org/bfa/login

If there is no chapter in your area, please consider starting one! Or select the closest chapter and arrange to pickup your materials there.

Grower Members can participate in the group ordering directly through us by contacting agronomy@bionutrient.org, but you are still encouraged to go through your local chapter to get the best rates on shipping.

Note: As we are transitioning to the new schedule in Spring 2017, we will work to fulfill all orders submitted before May 15, but note that we are limited to current inventory on hand.

Descriptions and staff agronomist notes

Listed below are further details about the amendments we offer, with a few notes from our staff agronomist on usage and application rates.

Note that you should always check with your organic certifier before using any product.

Boron 10%

Recommended method of application: Broadcast spreader
Material: Granular

This is a granular calcium borate product with 10% boron. It is released slower in the soil than sodium borate, making it less prone to leaching and causing excesses.

The yearly application limit is 20 lbs per acre/year. (2 lbs actual boron)

Organic use requires a soil test showing deficient boron. Always check with your organic certifier before using any product.


Copper Sulfate 15% Cu 6% S Granular

Recommended method of application: Broadcast spreader
Material: Granular

This is a granular copper sulfate product with 15% copper. It is released slower in the soil than the water-soluble copper sulfates, making it less prone to leaching and far less harsh on soil microbiology.

The yearly application limit is 53 lbs per acre/year. (8 lbs actual copper)

Organic use requires a soil test showing deficient copper. Always check with your organic certifier before using any product.


Gypsum – Pelletized 21% Ca 16% S

Recommended method of application: Broadcast spreader
Material: Granular (pelletized)

This is a pelletized calcium sulfate (gypsum) product with 21% calcium. Calcium sulfate is a great form of plant-available calcium and sulfate, but note 2 caveats: 1) the calcium is only available once calcium base saturation rises above 60% (perhaps giving you some benefit as low as 50%), and 2) the sulfate in calcium sulfate, as with all sulfates, will NOT increase the sulfur levels on subsequent soil tests (for that, use elemental sulfur), it will only feed the crop and perhaps some the next year.

The yearly application limit is 2,000 lbs per acre/year.

May be allowed for use in organic production – pellets are made with 2% lignosulfonates. Always check with your organic certifier before using any product.


Iron 50% Fe 5% S

Recommended method of application: Broadcast spreader
Material: Granular

This is a granular iron sulfate product with 50% iron. Most soils have lots of iron and deficiencies are usually only seen in high pH soils with poor biological function. Generally, when iron is showing up as deficient, the recommendation is to add a small amount of iron sulfate, 50-100 lbs or so per acre, to feed the crop, until you can get your soil system working better (bring sulfur up to 50-100ppm and increase soil biological activity).

The yearly application limit is 200 lbs per acre/year. (100 lbs actual iron)

Organic use requires a soil test showing deficient iron. Always check with your organic certifier before using any product.


Manganese 28% 6% S (Granular)

Recommended method of application: Broadcast spreader
Material: Granular

This is a granular manganese sulfate product with 28% manganese. While the application limit for this product is 200 lbs per acre/year, it is usually best to apply it more slowly; 50-100 lbs per acre/year being a normal recommended amount.

The yearly application limit is 200 lbs per acre/year. (56 lbs actual manganese)

Organic use requires a soil test showing deficient manganese. Always check with your organic certifier before using any product.


Nitrate of Soda 16-0-0

Recommended method of application: Broadcast, or localized to the root zone
Material: Granular

This is a granular nitrate of soda (sodium nitrate) product with 16% nitrogen. This product is allowed for organic production in some places, by some certifiers. It should be used sparingly (or not at all if you have high sodium levels, or are still using potassium chloride fertilizer). It does give plants a nice growth boost early season, but be careful about using it too late in the season with fruiting crops (as opposed to leaf crops) as it can delay fruiting and maturity.

Check with your certifier about any potential restrictions on the use of sodium nitrate fertilizer. Always check with your organic certifier before using any product.


Sulfate of Potash Granular Organic 0-0-50 17%S

Recommended method of application: Broadcast spreader
Material: Granular

This is an organic, granular sulfate of potash (potassium sulfate) product with 50% potassium. The organic potassium sulfate we have is the only one produced in the U.S.A.

Always check with your organic certifier before using any product.


Sulfur 90% Granular Organic

Recommended method of application: Broadcast spreader
Material: Granular

This is an organic, granular elemental sulfur product with 90% sulfur. If you have deficient sulfur levels on your soil test, this is the product to fix it (sulfate fertilizers will not increase the stable sulfur levels in your soil, only feed your crops sulfate and eliminate excessive cations).

The yearly application limit is 100 lbs per acre/year. (90 lbs actual sulfur)

Always check with your organic certifier before using any product.


Trio Sul-Po-Mag 0-0-22 22% S 11% Mg

Recommended method of application: Broadcast spreader
Material: Granular

This is an organic, granular sulfate of potash-magnesia, sul-po-mag (also known as Kmag, or by the mineral name langbeinite) product with 22% potassium, 22% sulfur (as sulfate), and 11% magnesium. This is a great product if you need potassium and magnesium. It is a more readily available form of potassium than potassium sulfate and slower acting form of magnesium than magnesium sulfate (epsom salt). This product should be used mainly to feed the crop over a season and should be thought of less as a soil mineral balancer (it will add a bit to the potassium and magnesium on a soil test, but is not the most efficient way to build those levels).

Always check with your organic certifier before using any product.


Zinc 36% 5% S (Oxysulfate) (Granular)

Recommended method of application: Broadcast spreader
Material: Granular

This is a granular zinc sulfate product with 36% zinc. Zinc levels should match phosphates levels on a soil test... if you are deficient phosphate, zinc should be on the low side. High phosphates necessitates high zinc levels to keep the system balanced.

The yearly application limit is 35 lbs per acre/year. (12.6 lbs actual zinc)

Organic use requires a soil test showing deficient zinc. Always check with your organic certifier before using any product.


Greensand

Recommended method of application: Drop spreader, or Broadcast
Material: a dusty sand

Please note, we have a limited supply of Greensand and the only quarry that was producing it has permanently shut down. Until a new quarry comes online (possibly in Texas in 2017), Greensand will be unavailable once sold out.

This is a natural, mined mineral from New Jersey that contains over 30 elements, including around 7% potassium and 12% iron. Greensand has a mineral in it called glauconite, which slowly becomes a form of high-energy clay as soil biology breaks down the greensand. This is how it is possible that greensand is known to both loosen up clay soils and also help to aggregate light, sandy soils. This is a great product for boosting biological function, as that is the only explanation for the increase in nutrient availability post-application... you actually get more minerals showing up on tests of available plant nutrients than there are in the bag. Use anywhere from a few hundred pounds per acre up to 4,000 or more if you need the potassium. Generalized recommendations would be for 200-800 lbs per acre, with smaller annual maintenance applications.

Always check with your organic certifier before using any product.


TN Brown Rock Phosphate

Recommended method of application: Drop spreader, or some Broadcast spreaders
Material: medium-course powder

This is a mined rock phosphate that looks and feels a lot like soil. It contains around 3% available phosphate (but 27% total phosphate that your microbes can work on unlocking for your plants). Use where phosphate is needed at the rate of 300-500 lbs per acre, or more in soils very deficient in phosphate.

Always check with your organic certifier before using any product.


Montmorillonite Clay (PANAK-ITE Trace Minerals)

Recommended method of application: some Broadcast spreaders
Material: dusty 1/8" screened “quarry-run”

This is a natural, mined clay with lots of trace elements (likely all naturally occurring ones, actually). Montmorillonite clays are very “high-energy clays” and have extremely high exchange capacities, so they can hold onto lots of cations. Unlike most “montmorillonite” clays on the market, this one is actual montmorillonite, as opposed to the bentonite clays with relatively less sodium and elevated calcium levels compared to typical bentonite. This would make an excellent additive (in small amounts, 5-10% max) to seed starting mixes, potting soils, compost, or any garden soil (especially sandy ones).

Always check with your organic certifier before using any product.


Humates (screened)

Recommended method of application: Broadcast spreader
Material: dusty 1/8" screened

This is a natural, mined humate. Humates are stable organic compounds that provide a physical home to soil microbiology, as well as providing mineral exchange capacity for both cation and anion elements. Furthermore, they likely have some electro-chemical effects that lead to their ability to stimulate biological activity. Humates, as well as a form of biology-feeding carbon (like sugar or molasses) should always be applied when applying nitrogen, and is a good idea when applying trace element fertilizers (or any fertilizers), as the humates can help to buffer the harsh effects of fertilizers on soil biology. Apply 25-150 lbs per acre/per year.

Always check with your organic certifier before using any product.


Wollastonite Tailings

Recommended method of application: Drop spreader, or some Broadcast spreaders
Material: dusty 10-mesh, course powder

This is a natural, mined calcium silicate material. It is a tailings product from a calcium silicate mine so the wollastonite content will vary but should be around 20% (but no guarantees). The other minerals in the wollastonite tailings are also potentially valuable though, as generic “rock dust” materials (calcium-rich rock dust). Calcium silicate provides both calcium and plant-available silica. There is increasing evidence that silicon-deficiency is an under-appreciated issue in farming today. Amending with calcium silicate has been shown to help prevent powdery mildew, so it's worth giving this material a try. Apply 500-2000 lbs per acre (assuming you need the calcium), with smaller maintenance applications thereafter, but make sure you don't apply too much calcium.

Always check with your organic certifier before using any product.


Carbonatite

Recommended method of application: Drop spreader, or some Broadcast spreaders
Material: a dusty sand

This is a natural, mined volcanic calcium mineral. It is reactive (available) and contains many different minerals and trace elements in a non-leachable, but biologically available material. It is roughly 33% calcium carbonate, 7.5% clay compounds like biotite, vermiculite, greensand, etc, 6% rock phosphate, and 4% trace elements. Unless you have excessive Calcium, this is a great product to use. Contains about 19.5% Calcium, 1.3% Magnesium, 0.8% Potassium, 3.8% Iron, and 3.2% Phosphate. When you need calcium, this is a fantastic product to use. Apply 500-2000 lbs per acre (assuming you need the calcium).

Always check with your organic certifier before using any product.


Dynamin

Recommended method of application: Drop spreader
Material: powdery clay

This is a natural, mined clay material. Containing a wide variety of available elements, including excellent levels of trace elements, Desert Dynamin stimulates soil microbiology and helps to trap ammonia and nitrate nitrogen. Contains roughly 3.8% Calcium, 2.4% Magnesium, 1% Potassium, and 2.7% Iron. Apply 100-1000 lbs per acre, use as a livestock supplement free-choice, or add to compost or manure.

Always check with your organic certifier before using any product.


Florida soft rock phosphate (Calphos)

Recommended method of application: Drop spreader, or some Broadcast spreaders
Material: medium-course powder

This is a mined rock phosphate from Florida. It contains around 3% available phosphate (but 20% total phosphate that your microbes can work on unlocking for your plants). Also contains 20% calcium as calcium oxide. Use where phosphate is needed at the rate of 250-1000 lbs per acre, or more in soils very deficient in phosphate.

Always check with your organic certifier before using any product.


Basalt fines

Recommended method of application: Drop spreader, or some Broadcast spreaders
Material: dusty course powder

Natural, mined paramagnetic rock powder stimulates soil microbiology and supplies minerals and trace elements. Apply 500-20,000lbs per acre.

Always check with your organic certifier before using any product.


Aragonite

Recommended method of application: Drop spreader, or some Broadcast spreaders
Material: dusty course powder

Aragonite is a natural, mined mineral that is made of ancient shellfish and ocean precipitates. It is roughly 37% calcium as calcium carbonate and has very low levels of magnesium. It also has very good levels of trace elements. Apply as needed for proper calcium soil levels and up to a few hundred pounds as a yearly maintenance application.

Always check with your organic certifier before using any product.


Coal screenings

Recommended method of application: Drop spreader, or some Broadcast spreaders
Material: dusty course powder

This is a natural, mined form of concentrated carbon. This is a new product and as such, we would treat it as an experiment. This will have many of the same benefits of other sources of carbon like humates and compost, but much cheaper (concentrated humates are extracted from forms of coal). Use sparingly due to the possibility of some heavy metal contaminants, but levels should be low and not pose a risk (as with all dust, don't breath it). Apply up to a couple hundred pounds per acre.

Always check with your organic certifier before using any product.


Humus Compost

Recommended method of application: Some broadcast spreaders, manure spreader
Material: Sifted compost

Humus compost is a compost product that is produced under controlled conditions over a period of time allowing for the growth of a wide array of microbiology, especially fungi, that works to “humify” a portion of the organic matter. This is a high quality compost and we recommend it as a potting soil additive or soil top dress. Apply 500-4000 lbs per acre, or more.

Always check with your organic certifier before using any product.


KS Plus (also called super sulfur potash)

Recommended method of application: Drop spreader, or some Broadcast spreaders
Material: Course powder

Potassium Sulfate Plus (KS Plus) is a natural, mined mineral that contains high levels of Potassium, Sulfur, Calcium, and trace elements. It is excellent at bringing energy into the soil system and massively increases biological activity in soil. Because it is a naturally mined product, levels of the various minerals can vary depending on the particular “batch”. The level of elemental sulfur ranges from 3-35% mostly because of the activity of the bacteria naturally present that oxidizes the sulfur. Sulfate forms range from 10-70%. There are many different oxidative states of sulfur in this product at any given time and this encourages a wider range of microbiology. Also present in the material is 5-35% calcium sulfate in a readily available form (much more than mined gypsum). Potassium is present (2.5-8.5%) in potassium sulfate as well as potassium silicate forms (potassium silicate has been shown to be a great source of available silica).

When KS Plus is mixed with compost and manure, it can convert volatile ammonia into ammonium sulfate, which is an excellent nitrogen source, and dramatically reduce odor and nitrogen losses. Apply 100-500 lbs per acre (assuming you need the sulfur and potassium), with smaller maintenance applications thereafter.

Always check with your organic certifier before using any product.


Sea Salt

Recommended method of application: Drop spreader, Broadcast spreaders, Soluble
Material: Small granular

This is a natural, mined sea salt. It has excellent levels of trace elements and will stimulate soil microbiology. In many places in North America, sodium can actually be deficient and plants will benefit from an application of sea salt. Apply 50-100 lbs per acre (assuming you don't have excessive sodium).

Always check with your organic certifier before using any product.


Humus Compost w/ Cobalt, Molybdenum, and Selenium

Recommended method of application: Some broadcast spreaders, manure spreader
Material: Sifted compost

This is our Humus compost product mixed with Cobalt Carbonate, Sodium Molybdate, and Sodium Selenate. Apply NO MORE THAN 250 lbs per acre, for the maximum yearly application of Cobalt, Molybdenum, and Selenium. 250 lbs of product contains approximately 6.3oz Molybdenum, 15oz Cobalt, and 1.6oz Selenium.

Always check with your organic certifier before using any product.
