Excellent source of calcium and sulphur

Catalis®, Agro-100’s newest nutriliming agent, is an excellent source of calcium and sulphur. Composed of 31% calcium and 9.7% sulphur in the form of sulphates for rapid absorption, Catalis® is designed to favour optimal crop production. Its dual capacity of liming and fertilizing makes it an ideal soil amendment agent for any fertilization program aimed toward reaching the full yield potential of many crops. Catalis® establishes optimal conditions for producing high yields. It is certified by the Bureau de normalisation du Québec (BNQ 3264).

Since most plants perform better in a pH ranging from slightly acidic to slightly alkaline, lime application on acidic soil is a prerequisite for the optimal use of nutrients. Catalis® is composed of calcium hydroxide (Ca[OH]2) and calcium carbonate. Calcium hydroxide offers a kick-start effect with its rapid action on pH. The calcium carbonate will take over and stabilize the pH for a long-lasting effect. Catalis® surpasses calcitic lime (calcium carbonate [CaCO3]) by elevating soil pH much more quickly. Its agricultural index of 72% (dry matter) and its rapid action on the pH make it highly recommended for acidic soils (recovery liming). By maintaining an optimal pH, Catalis® improves nutrient availability. It intensifies the biological activity of soils, since it creates favourable conditions to soil-life development (worms, bacteria). At the same time, structure is improved, which provides rapid water infiltration, reduces run-off and prevents the risk of erosion.

Catalis® is more than a liming agent. Calcium plays an essential role in the composition and growth of plant tissues as well as improving resistance to diseases and shocks. With its high calcium content, the nutriliming agent Catalis® limits physiological disorders associated with calcium deficiency (bitter pit in apples, blossom-end rot in tomatoes and peppers, tip burn in lettuce, etc.) and helps to produce fruits and vegetables that are better able to withstand preservation without any loss of quality that may be experienced at harvest. With Catalis®, food is richer in calcium and proteins (sulphur effect). In combination with regular fertilization, Catalis® activates and supports robust plant growth.

Sulphur is the other major component of Catalis®®. Today, sulphur is considered the fourth macronutrient with NPK for all cultivated plants. Sulphur is indispensable for the synthesis of proteins and chlorophylls and for the assimilation of nutritional elements, especially nitrogen coming from fertilizers or symbiotic fixation. Plants thus have a vital need in sulphur throughout their cycle including building up seed reserves. Sulphur is essential to reach the crop’s objectives in quality and organoleptic properties (rate of proteins, forage energy value, glucosinolates content in cruciferous crops, cysteine sulfoxides content in onions/garlic, etc.). Sulphur improves resistance and self-defense ability against stress. Furthermore, sulphur input helps to maintain the right nitrogen-sulphur ratio in the soil for matter to decompose. The reduction of atmospheric sulphur emissions and the use of sulphur-poor fertilizers contribute to a deficiency of this element in many crops. A sulphur deficiency in the soil leads to stunted growth and a loss in yield and quality at harvest, translating into a loss in revenue. Since atmospheric sulphur is no longer available, fertilization needs to be complemented with regular inputs of sulphur to ensure crop yield and quality. Catalis® is the cost-effective solution to address all crop needs in sulphur. The sulphur contained in Catalis® can be completely assimilated by the plant and is readily available in the form of sulphates. Indeed, about 80% of Catalis®‘s sulphur is in the form of sulphates (CaSO4), and the rest is in the form of sulphites (CaSO3). In the soil, calcium sulphite quickly transforms into calcium sulphate (CaSO4), making this element also available to the plant. Catalis® is particularly adapted to the needs of sulphur-intensive crops such as cruciferous crops, soybean, corn, potato, beet, alfalfa, clover, forage grass, etc. Catalis® can be applied in pre-plant in the spring, at growth start-up or following each cutting in forage crops or in the fall after harvest.

  • BNQ-certified fertilizing residual material (FRM)
  • Rapid and sustained action on soil pH
  • Immediate input of calcium and sulphur, both essential elements for plant growth
  • Stimulation of root establishment, plant growth and health, and chlorophyll formation (sulphur effect)
  • Stimulation of soil microbial activity
  • Value enhancement of fertilizers
  • Stimulation of nitrogen fixation by the nodules (sulphur effect)
  • Improvement of tolerance to biotic and abiotic stress
  • Recommended for all crops, but particularly in sulphur-intensive crops (cabbage, canola, alfalfa, soybean, corn, etc.)

In conclusion, Catalis® offers the dual capacity of liming and fertilizing in a single operation. On top of its positive impact on soil pH and providing precious essential nutrients to the plant, Catalis® improves soil health and optimizes yields. The high agronomic value and “nutriliming” synergy found in Catalis® make fertilization more profitable and promote an increase in productivity.
