Triple Super Phosphate

Short Description:

TSP is a multi-element fertilizer mainly containing high-concentration water-soluble phosphate fertilizer. The product is gray and off-white loose powder and granular, slightly hygroscopic, and the powder is easy to agglomerate after being damp. The main ingredient is water-soluble monocalcium phosphate [ca(h2po4)2.h2o]. The total p2o5 content is 46%, the effective p2o5≥42%, and the water-soluble p2o5≥37%. It can also be produced and supplied according to users' different content requirements.
Uses: Heavy calcium is suitable for various soils and crops, and can be used as raw material for base fertilizer, top dressing and compound (mixed) fertilizer.
Packing: plastic woven bag, net content of each bag is 50kg (±1.0). Users can also determine the packaging mode and specifications according to their needs.
(1) Powder: gray and off-white loose powder;
(2) Granular: The particle size is 1-4.75mm or 3.35-5.6mm, 90% pass.

Application: An efficient high analysis compound fertilizer. Suitable as a seeding fertilizer, base fertilizer or for top dressing.

The appearance of heavy superphosphate is similar to that of ordinary calcium, usually grayish white, dark gray or grayish black. The granulated fertilizer is usually a 1-5 granule with a bulk density of about 1100 kg / m. The main component of heavy superphosphate is monocalcium phosphate monohydrate.

Since the raw material phosphoric acid and phosphate rock contain impurities, the product also contains a small amount of other components. The general grade of international heavy-duty calcium phosphate is N-P2o5-K2O: 0-46-0. China’s industry standard for heavy superphosphate products, HG2219-9l, stipulates that: effective P2O5 ≥ 38% in heavy superphosphate is qualified, and P2 ≥ 46% is superior.

Granular heavy superphosphate can be used directly or as a phosphorus raw material for admixing fertilizers. Powdered granular super-superphosphate can be used as an intermediate product and other nitrogen or potassium-based basic fertilizers or trace element raw materials to be processed into a compound fertilizer containing various nutrients to meet the needs of different soils and crops. .

The advantage of heavy superphosphate is the high concentration of nutrients, and most of them are water-soluble phosphorus, which saves packaging and transportation costs and reduces field costs. Therefore, the construction of a heavy superphosphate device in the phosphate rock producing area is more economical and reasonable.

The other advantage of the product is that the P2O5 contained in the product is directly converted from low-cost phosphate rock. That is, more effective P2O5 can be obtained by producing a certain amount of phosphoric acid to produce heavy superphosphate than to produce ammonium phosphate.

Heavy calcium has obvious yield-increasing effects on most crops such as wheat, rice, soybean, corn, talented, etc., such as: can promote early maturity of rice, increase tillering, vigorous growth, thick stems, early heading, and reduce openness; Promote the growth and early maturity of maize seedlings, and promote the plant height, ear weight, grain number per spike, and 1000-grain weight; promote wheat growth in the flood season, robust plants, promote tillering, and have obvious yield-increasing effects; Not only does it maintain good nutrients in the soil, it also enhances root development, increases root numbers, and increases nitrogen supply. Yes, 1, centralized use, 2, mixed with organic fertilizer application, 3, layered application, 4, root external application.

It is a slightly acidic fast-acting phosphate fertilizer, which is single water-soluble phosphate fertilizer with the highest concentration at the time being.It mainly supplies plant phosphorus and calcium to promote germination, root growth, plant development, branching, fruiting and maturation.

It can be used as the raw material of base fertilizer, seed fertilizer, top dressing fertilizer, leaf spraying as well as compound fertilizer production.It can be applied alone or mixed with other nutrients. If mixed with nitrogen fertilizer, it can fix nitrogen.

It is widely applicable to rice, wheat, corn, sorghum, cotton, flowers, fruits, vegetables and other food crops and economic crops.

Low cost source of P and S in a wide range of pasture and cropping situations. SSP is a traditional product for supplying P and S to pastures, the main two nutrients required for pasture production. Source of P in mixes with N and K for a range of crop and pasture needs. Generally mixed with Sulphate of Ammonia and Muriate of Potash, but can be blended with other fertilisers.

-  TSP  has the highest P content of dry fertilizers without N. For over 80% of the total P is water soluble, it becomes rapidly available for plant uptaking, to promotes flower and fruit production and enhance the vegetable yields

-  TSP also contains 15% Calcium (Ca), providing an additional plant nutrient.

-  TSP belongs to acid fertilizer, used in alkaline soil and neutral soil, best to mix with farmyard manure, to improve the soil composition and increase soil nutrients.

Triple superphosphate (Total P2O5:46%)

Fertilizer represented as 0-46-0, is normally applied where plants are grown in soils with low or average levels of phosphorus. Its importance can be measured by the fact that in absence or it, the root development is weak, growth is stunted, productivity drops, the leaves or the edges of the leaves turn purple and in plants like tobacco and cotton, the leaves turn an abnormal color of dark green; potato tubers develop brown spots etc.

Because it is a fertilizer with slightly acidic composition, its effect is limited in neutral or alkali soils. Because the phosphorus in its composition dissolved easily in water, it shows its effects rapidly. TSP is used as a base fertilizer.

If it’s applied too early, the phosphorus in it combines with the lime and other elements in the soil and loses its effectiveness. If it is applied after the planting or seeding, it remains on the surface and has little effect. For these reasons, it should be applied either during or immediately after planting, seeding for maximum effect.

A kind of quick water-soluble phosphate fertilizer.

Mainly used as the raw material of Blending NPK fertilizers.

TSP is of high concentration of Water soluble phosphate which can powerfully improve the growth of plants or corps, enhance root development and the anti-pest ability.

TSP can be used as basal dressing, top dressing, seeding fertilizer or compound fertilizer, but it performs better when used as base fertilizer.

TSP is widely used for the cereals and cash crops as wheat, corn, sorghum, cotton, fruits, vegetables and so on.
