Organic growers now have access to an ancient sunken treasure of nutrients that can improve their food and fiber fortune.

Buried 1,000 feet below the surface of New Mexico where an ocean once existed 200 million years ago, a naturally-occurring, nutrient-rich mineral source... langbeinite... is now available as K-MAG NATURAL.

K-MAG NATURAL Delivers 3-in-1 Fertilizer to Organic Farmers
Organic Crops Need Balanced Fertility Soil fertility is one of the most important factors in organic and low-input farming.

Returning vital nutrients to the soil via composts, cover crops and manures has long been recognized as an effective and sustainable practice. However, achieving soil fertility levels necessary for optimal growth, quality and yield can be difficult when using these traditional organic crop amendments. It is very difficult to predict the rate of nutrient release from these materials and most do not contain nutrients in the correct ratios that plants require.

Recently listed by the Organic Materials Review Institute (OMRI) for use in organic production, K-MAG NATURAL is a unique, naturally-occurring combination of three essential nutrients — potassium (22% K20), magnesium (11% Mg) and sulfur (22% S). Because these nutrients are in the water-soluble, sulfate form, they are readily available to the crop.

Safe for Sensitive Crops
Many crops have a low tolerance for chlorides in the soil or from fertilizers. When excessive chloride is present, sensitive crops such as many fruits and vegetables, can have lower quality and shorter shelf life.

K-MAG NATURAL is a low chloride fertilizer source. Also, K-MAG NATURAL’s low salt index helps to minimize the risk of fertilizer “burn.”

Organic growers know that quality is a critical determinant of price premiums. Top quality crops require an adequate supply of all essential nutrients. If nutrient shortages exist, growth will be limited by the nutrient in shortest supply.

K-MAG NATURAL Helps Provide K, Mg and S in the Right Balance
Many organic crops must rely on their natural defense mechanisms to tolerate disease, insects and environmental stress. Maintaining proper soil fertility levels helps promote vigorous plants and healthy root systems that can better resist disease and pests, thereby improving crop yield and quality.

K-MAG NATURAL — Where it Comes From
K-MAG NATURAL comes from the world's largest and purest deposits of langbeinite ore, one of the most soluble salts deposited in an ancient ocean. Millions of years ago, part of what is now eastern New Mexico was a large, isolated lake of ocean water. As the water evaporated, langbeinite was deposited, and is now located 1,000 feet below the earth's surface.

Available Grades
To make this nutrient source of K, Mg and S available to organic agriculture, K-MAG NATURAL is extracted, crushed, washed and made available in two grades — Granular and Standard (smaller granules than Granular grade).

	Potassium is essential for protein synthesis and starch formation. It improves the flavor and color of fruits and vegetables, and promotes quality factors in growing crops. K promotes drought tolerance, winter hardiness, and disease and insect resistance.
	Magnesium is at the heart of the pigment-containing molecule, chlorophyll. As rates of photosynthesis decline, so do quality and yield.
	Sulfur remains a key element in crop proteins. It is a requirement for nitrogen fixation in legumes and vital to vitamin synthesis in all plants, important determinants of crop quality. Without sulfur, onions, garlic and mustard would not have their unique tastes.

	Immediate Nutrient Availability — K-MAG NATURAL is in the water-soluble, sulfate form, so its nutrients are readily available. K-MAG NATURAL Granular dissolves slower than Standard grade due to its larger granule size.
	Low Chloride — Many fruits and vegetables suffer from lowered quality and shorter shelf life when exposed to high chloride levels in the soil or from fertilizer. K-MAG NATURAL is low in chloride.
	Low Salt Index — K-MAG NATURAL’s low salt index helps to minimize the risk of fertilizer “burn.”
	Does Not Affect Soil pH — K-MAG NATURAL is a neutral salt and does not affect the soil pH. Many fertilizer materials do contribute to the acidity of the soil. Since most crops grow best in soils that are slightly acidic to slightly alkaline, a neutral salt such as K-MAG NATURAL does not contribute to reducing the soil pH below the desired range.
	Three Nutrients in One — All natural product of potassium (22% K2O), magnesium (11% Mg) and sulfur (22% S).
	OMRI Listed — Listed by the Organic Materials Review Institute (OMRI) for use in organic production, K-MAG NATURAL fits into organic soil fertility programs.
