Product Notes:

Granular format

» Download (PDF)

Uses

  • A good source of readily-available potassium, magnesium, and sulfur
  • Recommended source of magnesium when calcium/pH is too high to allow for use of dolomitic lime and/or when magnesium levels are below crop requirements (Mg from dolomite releases gradually over 3 years)
  • Not recommended as a potassium source when magnesium levels are already sufficient (use SOP instead)

Application rates

  • Soil testing is the best way to determine potassium and magnesium requirements
  • Long-term goal should be to maintain potassium at 2 to 5% base saturation, and magnesium between 11 and 20% base saturation, depending on soil CEC
  • Magnesium should be a minimum of 100ppm (200lbs/ac)
  • 300lbs/ac is considered a “maintenance level” when soil tests indicate a Mg deficiency
  • 500lbs/ac will gradually build Mg/K levels in the soil
  • Maximum recommended rate is 2200lbs/ac per year – not usually economical
  • Readily-available nature of this product makes it feasible to apply for current crop requirements

Comments

  • Other common names/brands are Sul-Po-Mag and K-Mag
  • Magnesium sulphate can be used to supply magnesium in cases where potassium levels are high/excessive

Uses

  • A rock powder with a broad range of minerals
  • Some evidence of increased microbial activity & nitrogen availability, particularly in combination with compost
  • Has a liming effect on soils: 52% CaCO3 equivalence (neutralizing value)
  • Lower total phosphorus and available phosphorus content than CalPhos but competitively-priced on a per unit basis
  • Clay content can improve nutrient-holding capacity on light soils
  • Large spectrum of trace minerals may help address “hidden hungers”

Application rates

  • Soil testing is the best way to determine mineral requirements.
  • Usually broadcast at rates of 0.5 to 2mt/ac

Comments

  • Other common names/brands are Sul-Po-Mag and K-Mag
  • Magnesium sulphate can be used to supply magnesium in cases where potassium levels are high/excessive

OMRI-Listed Sulphate of Potash (“Organic SOP”)

Product Notes:

Granular format

» Download (PDF)

Uses

  • A good source of readily-available potassium, sulfur

Application rates

  • Soil testing is the best way to determine potassium requirements
  • Long-term goal should be a 2% to 5% base saturation of K; woody perennials/vines will benefit from higher levels, even up to 7.5%.
  • The readily-available nature of SOP makes it feasible to apply for current crop requirements

Comments

  • Much lower salt index than muriate of potash (MOP), so considered better for soil life/biological activity
  • MOP a more economical choice where soil test levels/crop requirements indicate high application rates
  • Consider MOP for fall applications and SOP for spring/in-season applications to mitigate potential negative impacts of MOP on soil health

  • Can be broadcast at 1500-2000lbs/ac when economically viable

Comments

  • Much higher in nitrogen and other available macro-nutrients than most other organically-approved products.
  • Some organic corn producers report optimal economic yield gain at rates of 300lbs/ac as a banded starter fertilizer.
  • Company plot data has shown 39 bu/ac yield increases in corn; 7-12bu/ac in winter wheat; 5-6 bu/ac in soybeans when used as a starter.

» Download (PDF)

Uses

  • Very good option for liquid starter and foliar applications
  • Can also be applied through irrigation systems (including drip)
  • Supplies nutrients but more importantly feeds and stimulates soil microbial activity
  • Fish oils are fungal food sources

Application rates

  • Recommended to apply 4-5 gallons per acre per application (up to 3 applications per season)
  • Dilute 1:10 ratio for soil application, 1:50 for foliar application

Comments

  • A good way to supply nutrients and stimulate microbial activity early in the season (e.g. on winter cereals, as a starter fertilizer for corn and beans)

CalPhos

  • 20% total P2O5
  • 3% available P2O5
  • 20% Ca

Product Notes:

Spread with lime spreader or similar equipment

» Download (PDF)

Uses

  • A good option to build long-term phosphorus reserves, particularly when manure or compost sources of P are limited or unavailable
  • Not suited for soils already high in calcium

Application rates

  • Typical soil tests (P1/Olsen) measure available P, but not total P reserves, and what can be made available via biological activity over the growing season; consider P2 analysis, crop monitoring/tissue sampling for a more complete assessment
  • General recommendations based on experience:
    • 500lbs/ac for soils below 12ppm P1 phosphorus

    • 400lbs/ac for soils 12 to 15 ppm P1 phosphorus

    • 300lbs/ac for soils 15 to 18 ppm P1 phosphorus

  • Relatively low percentage of available P makes this product impractical/uneconomical to apply to meet current crop requirements; needs to be part of a long-term soil-building plan

Comments

  • CalPhos is also recommended as an addition to manure (in the bedding or during the composting process) to help stabilize nitrogen; it also increases available phosphorus from the CalPhos
  • Research indicates that it can take 4 to 8 weeks for phosphate rock to reach maximum solubility
  • P availability from phosphate rock fertilizers is positively correlated with AMF and green manure incorporation

Product notes

Eco-Tea™ is a 3-part system:

Inoculum – earthworm castings and plant-based compost “brewed” on-site into a concentrated liquid

Microbial foods – humic, fulvic, and long-chain amino acids, kelp extract, simple and complex carbohydrates, and enzymes designed to feed the specific bacteria, fungi, and protozoa in the tea. (this food is customized to different end uses (e.g. foliar vs soil vs seed)

Catalyst – used just before application to activate the specific disease suppressive groups of microbes in the tea. (foliar catalyst also contains natural wetting agents and surfactants)

  • Eco-Tea™ “Foliar” concentrate is “brewed” in Dorchester and shipped to the producer in 2 parts: Part 1 is a blended inoculum with microbial foods, aerated 24 hours prior to delivery. Part 2 is the catalyst. The producer adds the catalyst immediately prior to application, along with de-chlorinated water, tank mix well.
  • Greenhouse, high value ag crops, horticultural and viticultural operations with their own aerating equipment can also purchase the 3-part system and brew their own foliar product for regular applications. We can also sell a brewer system for this continual foliar use.
  • Eco-Tea™ “Foliar” is diluted with at least 3 parts water prior to application (e.g. 250ga of concentrate + 750ga water). It can be further diluted if more water needs to go down specific to farm/crop needs.
  • Chlorinated water needs to be aerated for minimum of 1 hour or sit for 24 hours before mixing with the Eco-Tea™ Foliar concentrate
  • Chloraminated water needs to aerated for a minimum of 48 hours before mixing
  • Eco-Tea™ “Foliar” is an active, aerobic product. Store out of direct sunlight. It should be used within 24-48 hours of delivery. With aeration equipment the product is good for 7 days if continually aerated. Once no longer aerating and the catalyst is added (tank mix) must be used within 8 hours.

Uses

  • Eco-Tea™ “Foliar” is ecologically engineered to reduce and suppress pest and disease pressure, including fungal and bacterial pathogens and some insects
  • Certain microbes consume pathogens, others produce small amounts of antibiotics in the presence of pathogens
  • Beneficial microorganisms in Eco-Tea™ foliar colonize the leaf surface, decreasing plant stress and out-competing pathogens for space and resources (competitive exclusion)

Application rates and timing

  • Approx. 2 gallons per acre of concentrate; a 250 gallon tote of concentrate will cover approx. 125 acres
  • Timing is similar to conventional fungicide applications; early morning or evening only, never in full sunlight, very overcast is okay
  • Eco-Tea™ foliar works best if the beneficial microorganisms are present just before the pathogen has a chance to attack:
    • Wheat: at heading (T3)
    • Corn: 6-7 leaf stage and/or at tasseling
    • Soybean: just before or at flowering
    • Oats: at heading
    • Alfalfa & Hay: after first cut
    • Ginseng: 21 day program, starting early June to Sept
    • Cranberry/Blueberry/Strawberry: 5 apps, mid-May to mid-Sept
    • Sunflowers: at flower (late July/early Aug), could warrant 2 applications
    • Vegetables: 7-10 day program, depending on weather and disease pressure, starting mid-June to early Sept *All new foliage needs to get covered*
  • Eco-Tea™ “Foliar” is a relatively coarse product; some equipment modifications are necessary to maintain the integrity of the microbiology during application (nozzle setting, psi and taking out screens are vital to maintain integrity)
  • Remove all filters from the sprayer
  • Apply with coarse nozzles only, *take all screens out*, low pressure (50psi or lower)
    • TeeJet Nozzle/Floodjet 0.08 (white) or larger
    • Boomless Nozzle 0.10 or larger
    • Liquid Kit Seeding (Discs) 30 or larger
    • Drip Tape, Compatible
    • GreenHouse Emitters 300 microns or larger
    • For berries with foliar applications high pressure is not recommended (blast sprayers), can also have the option of using catalyst as a biostimulant

Overton Environmental stocks these nozzles and other specialized application accessories and can ship to producers who cannot source parts locally

Clean up

  • Make sure to wash out equipment with clean water, take nozzles off and let flow. Citric Acid, Acetic Acid, Ammonium solution is best as cleaning medium.
  • DO NOT let sit in sprayer after application, clean immediately.

Comments

  • Foliar Eco-Tea™ is biologically engineered to stimulate or ‘wake up’ specific functional groups of disease suppressive microorganisms in the tea, when catalyst is added. The foliar catalyst is formulated differently than the soil amendment catalyst, with more seaweed extract and yucca, but with less humic and molasses.
  • This amendment is biologically engineered to provide specific beneficial disease suppressing microbes to the foodweb/biome.
  • No molasses is in the foliar catalyst
  • Yucca (spreading action ‘non-toxic’ soap) = surfactant in foliar tea
  • Bacteria focused to colonize leaf surface; it takes 20 minutes for microbes to colonize the leaf zone
  • In conventional systems Eco-Tea™ Foliar must have a 5-7 days window between fungicide applications (before and/or after Eco-Tea™ use)
  • Thompsons is conducting side-by-side field trials in wheat and other crops and will be tracking the crop response over the course of the 2017 growing season
  • Eco-Tea™ “Foliar” pricing is dependent on the volume ordered and shipping costs
  • Eco-Tea™ products are approved for organic production by Pro-Cert

Product notes

Eco-Tea™ is a 3-part system:

Inoculum – earthworm castings and plant-based compost “brewed” on-site into a concentrated liquid (“HDI”)

Microbial foods – humic, fulvic, and long-chain amino acids, kelp extract, simple and complex carbohydrates, and enzymes designed to feed the array of beneficial bacteria, fungi, and protozoa (this food is customized to different end uses–e.g. foliar vs soil vs seed).

Catalyst – used just before application to activate the biodiverse populations of plant beneficial microbes in the tea.

  • Eco-Tea™ “HDI” inoculum concentrate is “brewed” in Dorchester and shipped to the producer in 3 parts: 1) HDI (liquid inoculum) 2) microbial food, and 3) catalyst. A typical “HDI unit” is a 250Ga tote of HDI, a 20kg bag of microbial foods, and a 20L bucket of catalyst. The producer tank mixes the microbial foods and catalyst prior to application to “activate” the microorganisms, along with de-chlorinated water.
  • Eco-Tea™ “HDI” is diluted with 3 parts water prior to application (e.g. 250ga of concentrate + 750ga water + 20kg microbial food + 20L catalyst)
  • Chlorinated water needs to be aerated for minimum of 1 hour or sit for 24 hours before mixing with the EcoTea Foliar concentrate
  • Chloraminated water needs to aerated for a minimum of 48 hours before mixing
  • Eco-Tea™ “HDI”concentrate has a shelf life of 60 days (undiluted and before the addition of the microbial foods and catalyst) given it is stored out of direct sunlight.
  • Eco-Tea™ “HDI” is screened to 50 mesh/300 microns; foods and catalyst are water-soluble. (Greenhouse applicable)

Uses

  • Eco-Tea™ “HDI” is an abundant source of biodiversity for your soil. (billions of microbes of 129,000 different bacteria alone) These are plant growth promoting and ecologically functional microbes, including bacteria, fungi, and protozoa that give your root system a competitive advantage
  • EcoTea restores biodiversity to soils, increases nutrient availability, makes for better nutrient use efficiency, stimulates plant growth (especially at the root level), improves soil nutrient retention, and increases pest resistance and disease suppression
  • Eco-Tea™ “HDI” can be applied in-furrow or as a soil drench at seeding
  • Eco-Tea™ “HDI” can also be applied after forage cuttings to improve re-growth of both shoots and roots
  • Eco-Tea™ “HDI” can be applied post-harvest to aid in the fungal decomposition of residue, reducing pest and disease carry-over and improving nutrient retention; spray and incorporate so that organisms are not exposed to sun and can populate the residue and topsoil. Incorporation by a light harrow is best. Full till works as well

Application rates and timing

  • Typically 2.5 gallons per acre of concentrate diluted 3:1 with water; a 250 gallon tote of concentrate will cover 100 acres

Apply:

Apply with a coarse nozzle at low pressure (50 psi or lower)

  • TeeJet Nozzle/Floodjet 0.08 (white) or larger
  • Boomless Nozzle 0.10 or larger
  • Liquid Kit Seeding (Discs) 30 or larger
  • Drip Tape, Compatible
  • GreenHouse Emitters 300 microns or larger
  • Disc Seeder: ¼” line is best (e.g. Alpine kit – b/w 20-60 orifice)

Overton Environmental stocks these nozzles and other specialized application accessories and can ship to producers who cannot source parts locally.

Clean up

  • Make sure to wash out equipment with clean water, take nozzles off and let flow. Citric Acid, Acetic Acid, Ammonium solution is best as cleaning medium.
  • DO NOT let sit in sprayer after application, clean immediately.

Comments

  • Soil “HDI” Eco-Tea™ Program consists of three parts, 1) liquid inoculum 2) Microbial Food 3) Liquid Catalyst + de-chlorinated water (3:1)
  • Soil-applied Eco-Tea™ is biologically engineered to activate a more diverse functionality of beneficial microbial groups. For example, siderophore producers, phosphorous solubilizers, acetic acid producers, phytohormone production, iron scavenging etc.
  • This type of a diverse population of microbes stimulates tertiary and quaternary root systems and gives the plant a head start in growth, supplying your plant with vigor.
  • Soil “HDI” Tea adds “Tilth” to soil overtime, reducing crusting and creating stable soil aggregates.
  • ‘Bombarding’ soil system with as many biodiverse beneficial microbes as possible is the biologically engineered success of Eco-Tea™.
  • With seed treatment, good results so far, still in the testing phase.
  • Eco-Tea™ “HDI” pricing is dependent on the volume ordered and shipping costs
  • Eco-Tea™ products are approved for organic production by Pro-Cert

Product notes

Eco-Tea™ is a 3-part system:

Inoculum – earthworm castings and plant-based compost “brewed” on-site into a super-concentrated liquid (much more concentrated than soil or foliar products)

Microbial foods – humic, fulvic, and long-chain amino acids, kelp extract, simple and complex carbohydrates, and enzymes designed to feed the array of beneficial bacteria, fungi, and protozoa (this food is customized to different end uses–e.g. foliar vs soil vs seed).

Catalyst – used just before application to activate the biodiverse populations of plant beneficial microbes in the tea.

  • Eco-Tea Liquid Seed Treatment is shipped to the producer in 3 parts: 1) concentrated liquid inoculum 2) microbial food, and 3) catalyst. The producer tank mixes the microbial foods and catalyst prior to application to “activate” the microorganisms.

  • Eco-Tea concentrated inoculum has a shelf life of 60 days (before the addition of the microbial foods and catalyst) given it is stored out of direct sunlight.

  • Eco-Tea Liquid Seed Treatment must be used within 3 days of mixing.

  • Treated seed must be planted within 3 days of treatment (the sooner the better).

Uses

  • Eco-Tea Liquid Seed Treatment inoculates seeds with abundant populations of diverse plant growth promoting and ecologically functional microbes, including bacteria, fungi, and protozoa.

  • These microbes improve root development, nutrient use efficiency, and disease tolerance.

Application rates and timing

  • Cereals: 500ml treats 70-115 lbs of seed (i.e. 250ml/unit)

  • Beans: 500ml treats 50-70 lbs of seed (i.e. 500ml/unit)

  • Forage & Small-Seeded Crops (alfalfa, canola, etc.): use EcoTea HDI in-furrow

  • Mix the 3 components and apply to seed within 3 days.

  • Plant treated seed as soon as possible, no later than 3 days after treatment

  • Beans do require some time after inoculation to dry or else seed may bridge or become challenging to work with. Treating the seed one step before making the final transfer to the seeder will help eliminate bridging potential. Use “HDI” in-furrow treatment for best results with beans.

Comments

  • Compared to EcoTea “HDI” soil treatment, the liquid seed treatment is more economical but will have less of a beneficial impact on overall soil health: this product inoculates the seed rather than the soil
  • ‘Bombarding’ the developing root system with as many biodiverse beneficial microbes as possible is the biologically engineered success of Eco-Tea.
  • Experience has shown a positive impact on root development even in seeds that are also treated with conventional fungicides and insecticides
  • EcoTea products are approved for organic production by Pro-Cert
