Soil Amendments
N-P-K

OTHER AMENDMENTS


Soil amendments are usually single purpose products that address a specific soil problem. They are normally used when there is a major soil deficiency or imbalance to be overcome or to address a specific problem during the growing season. Fertrell carries an outstanding selection of these soil amendments. Some of them are used in our blended fertilizers. Fertrell has the expertise to consult with you on the use of these products and make recommendations for their use.
 

Nitrogen (N) Sources

ALFALFA MEAL is a reasonable alternative to blood meal as a source of nitrogen and is nicely balanced with phosphorous and potassium. Its carbohydrates and pro­tein make it an excellent soil conditioner by encouraging microbial activity in the soil. Micronutrients are plentiful because its extensive root system provides them to the plant from deep below the earth's surface. Typical Analysis: 2.5-3% N based on protein. 3 lb, 50 lb Bag

BLOOD MEAL is a fast release source of organic nitro­gen. It should only be used on plants that have a high nitrogen requirement. It may also be used in compost piles to increase the speed of the decomposition process. Tends to act as a deer repellent. Typical Analysis: 12-0-0.  50 lb Bag

CHILEAN NITRATE is a mined natural source of ni­trogen from Chile. It is quite water soluble and therefore readily available. Typical Analysis: 16-0-0.  50 Lb Bag

COTTONSEED MEAL is an excellent slow release or­ganic source of nitrogen for acid loving plants because of its low pH. Typical Analysis: 6-2-1. 50 Lb Bag

FISH MEAL is an excellent source of organic nitrogen and phosphorous. It is high in carbohydrates and protein which will stimulate biological activity in the soil and increase tilth. The nutrients are released through micro­bial activity in the soil. Thus it is long lasting and does not leach. Typical Analysis: 9-3-1. 50 Lb Bag

FEATHER MEAL is an ideal source of nitrogen for all crops requiring a steady long lasting supply of that ele­ment. The product is not very water soluble, therefore leaching away from crops is almost nonexistent. The ni­trogen is made plant available through microbial activity. Typical Analysis: 13-0-0. 50 Lb Bag

Phosphorous (P) Sources

BONE MEAL, STEAMED is an excellent source of plant available phosphorous. It also contains a minor amount of nitrogen and a large amount of calcium. This product can be used for general application or as a starter fertilizer for new plantings or transplants. Typical Analy­sis: 1-11-0. 50 Lb Bag

FLORIDA ROCK PHOSPHATE is an excellent source of phosphorous, calcium and essential trace elements. Florida Rock Phosphate is a high carbon rock phosphate that has approximately one fifth the neutralizing power of lime. It releases best at a lower pH so apply before liming. 50 Lb Bag

CAL PHOS is a valuable tool when soils show deficien­cies of calcium and phosphate. It is available in granular as well as pulverized form. Also Available In Granular Form OMRI 50 Lb Bag

TOP

Potassium (K) Sources

JERSEY GREENSAND is mined from naturally occur­ring deposits in New Jersey. It is an iron-potassium sili­cate that is excellent at loosening clay soils. Known for its moisture holding capacity (10 x), and the 30+ trace minerals it contains, it becomes a premiere soil condi­tioner for all agricultural and horticultural applications. OMRI 10 lb, 50 lb Bag

SULFATE OF POTASH is a potassium and sulfur product used in potassium deficient soils. Typical Analysis: 0­0-50-20S. 50 Lb Bag

SUL-PO-MAG is a soluble sulfate of potash-magnesia. It is a crushed mineral that will not alter the soil pH. Ap­ply where magnesium and potassium are deficient and calcium is abundant. Typical Analysis: 0-0-22- 22S-18 Mg   50 lb Bag

Other Soil Amendments

ARAGONITE is a sea calcium that is exceptionally high in calcium and low in magnesium. Many soils have had dolomite lime added for years and the magnesium may be tying up other nutrients in the soil. Gypsum and ara­gonite should be used to off set a high mag content soil. Typical Analysis: 0-0-0-39 Ca.  50 lb Bag

AZOMITE. Trace mineral fertilizer is a complex of natu­rally occurring minerals which contains essential elements (micro-nutrients) for plant growth. Azomite can improve soils that have been depleted of important minerals and micronutrients. It is 100% natural with no additives, syn­thetics or fillers. It is also an excellent anticaking agent for feeds. Available in micronized and granular form. OMRI 44 lb Bag

DEHYDRATED CHICKEN MANURE (LAYER) An excellent source of nitrogen, phosphorous and potas­sium and trace elements. It is an extremely good source of organic matter. Typical Analysis: 3-5-4.   50 lb Bag

CRAB MEAL. A potent organic fertilizer derived from the Blue Crab after 40% of the crab meat has been re­moved. Shells are kiln dried and pulverized into a beige colored meal. NPK averages 5-2-5 with over 13% natu­ral calcium, which virtually eliminates blossom-end rot in tomatoes and peppers. Over 30 trace elements and vi­tamins. Apply 5 Ibs. per 45-60 feet of garden row or 2 tablespoons per 1 gallon pot.  50 lb Bag

GreatGrow VERMICOMPOST TEA GRANULES. An all-natural, dry application of vermicompost's beneficial microbes. Designed for the sustainable, long-term enhancement of plants and soil. 5 lb, 50 lb Bag

GYPSUM (CALCIUM SULFATE) is an outstanding soil supplement for soil lacking calcium, but the pH is adequate or high. Gypsum will loosen the soil, encourage soil life, and add the needed calcium. Calcium also acts as a weed deterrent as most weeds prefer acid soils. The sulfur when combined with water will form a weak sul­furic acid which will release calcium that is tied up in the soil solution. This is quick reaction product. Typical Analysis: 0-0-0-23 Ca. -17 S.  50 Lb Bag

MENEFEE HUMATE is a natural humic acid based granular soil conditioner that acts as an organic chelator and microbial stimulator. Menefee Humate will signifi­cantly improve poor soils when used in combination with a balanced fertilization program.  50 Lb Bag

HI-CAL LIME (PULVERIZED) Use to raise the pH of the soil and increase the release of phosphorous and potassium from their insoluble compounds, making them plant available. Use in conjunction with gypsum on soils where the magnesium is out of balance (high). It loosens clay soil and binds the soil particles together in sandy soils. In order to be of immediate use and continue to break down gradually, the pulverized form should be used. Hi-Cal lime has less than 5% magnesium oxide. 50 Lb Bag

KELP MEAL It has often been said that if you do nothing else to your soil, apply kelp meal. Kelp meal contains all the nutrients from A to Z. It conditions the soil, builds soil life, stimulates root development and plant growth, and retains moisture in the soil. Our kelp meal is dehydrated and chopped seaweed of the Ascophylum nodosum variety (tidal water seaweed). Increases yields. Reduces effect of drought, and frost. It's not water soluble and has to be released to the plants by microbial activity. Takes about two (2) weeks to become plant available. Request OMRI if needed 4 Lb and 50 Lb Bag

MAGNESIUM SULFATE (EPSOM SALT) Magnesium is a key element in the plants production of chlorophyll and the photosynthesis process required for plant life. If soil tests reveal a deficiency in magnesium, this product should be considered. 50 Lb Bag

VITAZYME The Natural Soil Fertility Booster for healthier, more productive crops and soils. Vitazyme can be used in both conventional and organic production systems. It can benefit you: it's inexpensive, very cost-effective; easy to use; safe and nontoxic; it can be seed applied; it can be mixed with liquid fertilizers and pesticides. Expect better tilth and permeability in your soil with Vitazyme use. 2 1/2 Gal Jug

WORM CASTINGS A well balanced soil amendment providing a rich mixture of micronutrients, microbial organisms and organic matter. They contain an almost equal percentage of nitrogen, phosphorous and potassium plus calcium, and magnesium. An excellent top dressing for plants. Can be added to potting mix, houseplants and raised beds. 30 Lb Plastic Bag
