YaraVera AMIDAS 40-0-0

YaraVera® Amidas™ (40-0-0 5.5 S) is a homogeneous granular fertilizer containing urea and ammonium sulfate. Its 7.3:1 N to S ratio is optimal for grain crop fertilization. By combining urea and ammonium sulfate into one particle, N and S uptake by plant roots is increased compared to physical blends.

Product and safety information

Product application advice

Alfalfa / Lucerne

Alfalfa: 100-200 lbs YaraVera® Amidas® 40-0-0/acre at planting according to soil test. YaraVera® Amidas® is an excellent source of readily available sulfate sulfur. It is delivered in a 7.3:1 N to S ratio which is ideal for amino acid and protein production. Consult your agronomist for local recommendations.

Beans

Beans: 50-300# YaraVera® Amidas® 40-0-0/acre applied in split applications according to soil test; 50# pre-plant, followed by applications 20 days after emergence and prior to flowering. Cease applications of nitrogen prior to pod fill in order to preserve seed quality. YaraVera® Amidas® is also an excellent source of readily available sulfate sulfur. It is delivered in a 7.3:1 N to S ratio which is ideal for amino acid and protein production. Consult your agronomist for local recommendations.

Carrots

Carrot: 200-400 lbs YaraVera® Amidas® 40-0-0/acre in split applications. Approximately 25 % N applied at planting , the balance applied at 3-4 leaf stage. YaraVera® Amidas™ is an excellent source of readily available sulfate sulfur. It is delivered in a 7.3:1 N to S ratio which is ideal for amino acid and protein production. Consult your agronomist for local recommendations.

Cereals

Cereals: 250-425 lbs YaraVera® Amidas® 40-0-0/acre in split applications depending upon yield expectations and soil test. For winter grains, spring top dress applications are most efficient. YaraVera® Amidas™ is an excellent source of readily available sulfate sulfur. It is delivered in a 7.3:1 N to S ratio which is ideal for amino acid and protein production. Consult your agronomist for local recommendations.

Canola

Oilseed rape: 200-375 lbs YaraVera® Amidas® 40-0-0/acre depending upon yield expectations and soil test. Apply in the spring for most efficient results. YaraVera® Amidas™ is an excellent source of readily available sulfate sulfur. It is delivered in a 7.3:1 N to S ratio which is ideal for amino acid and protein production. Consult your agronomist for local recommendations.

Sorghum

Sorghum: 200-400 lbs YaraVera® Amidas® 40-0-0/acre depending upon yield expectations and soil test. Approximately 30% applied at planting, with the balance applied at the 3-4 leaf stage. YaraVera® Amidas™ is an excellent source of readily available sulfate sulfur. It is delivered in a 7.3:1 N to S ratio which is ideal for amino acid and protein production. Consult your agronomist for local recommendations.

Sunflower

Sunflower: Apply 200-450 lbs YaraVera® Amidas® 40-0-0/acre depending upon yield expectations, previous crop (nitrogen credit) and soil test. Depending upon cultural practices, apply 50-70% pre-plant with the remainder side dressed. YaraVera® Amidas™ is an excellent source of readily available sulfate sulfur. It is delivered in a 7.3:1 N to S ratio which is ideal for amino acid and protein production. Readily available sulfur is also beneficial to oil production. Consult your agronomist for local recommendations.

N:S ratio

No Segregation

YaraVera AMIDAS' unique homogeneous composition will not segregate

YaraVera AMIDAS has 40% nitrogen and 5.5% sulphur in the same granule. It's totally water soluble and very uniform in granule size. It is a truly homogeneous product that ensures uniformity of application. The ammonium nitrogen and sulphate sulphur are immediately available to plants. AMIDAS's N:S ratio of 7.3:1 is ideal for most crops.

Homogeneous

Optimal plant uptake of both N and S

YaraVera AMIDAS is a unique granular homogeneous fertilizer that contains nitrogen and sulphate sulphur readily available to the crops in an ideal N:S ratio of 7.3:1 - optimal for amino acid and protein synthesis. 

The presence of ammonium sulphate in the same granule as urea promotes optimal plant uptake of both N and S.

N and S are essential for plant structural and functional protein development. Applying these nutrients together with the AMIDAS homogeneous product helps assure top yields by supplying N and S in the forms the plant needs.

Even Distribution

YaraVera AMIDAS produces an even distribution pattern

Each granule of YaraVera AMIDAS is a homogeneous chemical mixture of N and S in the form of urea and ammonium sulphate. It cannot segregate. Fertilizer blends can segregate during handling and storage in the bag, pile, in the spreader hopper and during spreading. Once segregated, an uneven application of nutrients results.

Another consideration is that the spreading width of small, light particles is less than that of a larger, heavier particles in a blended mixture. The result is uneven nutrient application causing striped fields and reduced yields. Also, nitrogen and sulphur in the same granule enhances root uptake compared to blends, resulting in balanced nutrition for optimal plant growth.

Hardness

YaraVera AMIDAS is harder than many other fertilizers

Storing and handling of fertilizers can result in a breakdown of particles due to crushing. Harder fertilizers, such as YaraVera AMIDAS, have fewer broken granules, produce less dust and provide more uniform spreading.

In a demonstration, non-Yara urea crushed at just 4.5 kilograms of pressure. AMIDAS is much stronger, withstanding 7 kilograms of pressure before crushing. The result is a product that maintains a more uniform particle size all the way through to spreading on the crop. Fertilizer granules with a crushing strength of <3 should not even be used with spinner speeds > 700 rpm.
