General Information


CaTs contains 6% calcium and 10% sulfur. Each gallon of CaTs contains 0.63 pounds of calcium (Ca) and 1.04 pounds of sulfur (S). CaTs may be applied by drip, sprinkler, or flood irrigation. It may be blended with other fertilizers or applied as a foliar treatment on selected crops. When used as a foliar nutrient, CaTs should first be diluted with water before applying. Blends of CaTs should not be acidified below a pH of 6.0. CaTs may be used as a nutrient for the correction of Ca deficiency and as a soil amendment. CaTs is an efficient source of soluble calcium and sulfur to aid in the correction of these nutrient deficiencies in fruit and vegetable crops.

CaTs is compatible with most fertilizer solutions. CaTs is not compatible with phosphate fertilizers. In absence of specific recommendations and data, a jar test is recommended before mixing large quantities. The addition of water to the mixture may be helpful to maintain blend stability.

When blending with micronutrients and pesticides, trial blends should be conducted before beginning large scale mixing. When mixing other liquid fertilizers and/or pesticides with CaTs, the blend sequence should be as follows: water, pesticide, CaTs and/or other fertilizer.

CaTs may be applied to a wide variety of ornamental, turf, greenhouse, and other agricultural crops. Calcium requirements for most crops increase dramatically during periods of rapid growth and fruit development. Application of CaTs should be made based on soil and/or plant tissue analysis for calcium.

DO NOT apply to foliage of crops sensitive (foliar burn) to sulfur. DO NOT apply to foliage of any crop when temperatures are above 90° F. Apply CaTs in the early morning or late evening.

Pop-Up Fertilizers Many crops are sensitive to salts during germination. When soil moisture is low, delayed crop emergence and/or phytotoxicity may occur when fertilizer is placed too close to the seed. Do Not use CaTs in pop-up fertilizer when soil moisture is limited, soil salinity is above an electrical conductivity of 2 or when irrigation is delayed such that germination may be affected.

Limitations, Restrictions, and Exceptions


For band application: apply at the rate of one gallon per acre per inch of band width. (An eight inch band would require an 8 gallon per acre rate.) CaTs may be applied to a wide variety of agriculture crops, turf, ornamentals and greenhouse plants. CaTs may be broadcast, banded or knife injected as a source of calcium and sulfur. Rates may vary between 10 to 40 gallons per acre (GPA). Broadcast application rates are dependent on soil type, water quality and method of irrigation.
